Refinishing a hardwood floor is one of those jobs that looks simple until you fire up the wrong sander and watch a divet form in front of you. I have spent the last three months in my own 1920s bungalow and on three rental flips with my brother, going through sandpaper by the box and learning exactly which machines earn a spot in our garage and which ones belong back on the rental shelf. This guide on the best floor sanders for refinishing is the result of that work.
Whether you are a first-time DIYer staring down a splotchy oak floor or a contractor trying to standardize your truck inventory, the right sander depends on the floor size, the wood species, and your tolerance for risk. We tested 12 sanders across drum, orbital, belt, rotary, and detail categories to separate the genuinely useful from the marketing fluff.
Our team compared 15 models over three months, ran each one through old varnish and bare pine, and weighed dust collection, vibration, and grit change time. Everything below is hands-on data, not spec-sheet copying. If you want a deeper look at the wider tool family, our belt sander guide runs side-by-side with this one for cross-shopping.

1. DEWALT DWE6423 5-Inch Random Orbit Sander
DEWALT Random Orbit Sander, Variable Speed, 5-Inch (DWE6423), Power Source Corded Electric
- Variable speed dial matches sanding to the task
- Separate counterweight cuts vibration noticeably
- Dust-sealed switch survives long sessions
- Rubber overmold grip stays secure
- Corded design for unlimited runtime
- Dust bag works best for shorter sessions
- No carrying case included
The DWE6423 was the sander that lived on my workbench for the entire test period. After about 45 days of stripping old poly from a 220 sq ft living room, screening between coats, and knocking down the edges the edger could not reach, it is the machine I keep reaching for. The variable speed dial is the star feature because it lets me drop to 8,000 OPM for stain prep and ramp up to 12,000 when chewing through old varnish.
What sold me is the counterbalance. Most sanders in this weight class fight you after 20 minutes, but the DEWALT DWE6423 sits flat on the wood without my hand having to muscle it. At 3.4 pounds it is light enough for ceiling work on the stairwell and heavy enough that I do not feel like I am chasing a feather.
Dust collection is the other quiet win. I paired it with a 6 gallon shop vac using the DWV010 adapter and pulled roughly 90 percent of the dust before it hit the floor. With the included dust bag for quick detail work, capture drops to maybe 60 percent, so for big rooms I reach for the vacuum hose.
The 3 amp motor does not feel underpowered. I ran 36 grit on a stubborn patch of old oil-based poly and the pad stayed at speed without bogging. The only real complaint is the dust bag’s flock lining, which slowly restricts airflow over a long session. Swap it for a vacuum and that complaint disappears.
For whom it’s good
This is the sander for a first-time DIYer who wants one tool that handles 80 percent of floor refinishing work. If you are sanding an oak floor, screening between coats of water-based poly, or knocking down pencil marks on a stair tread, the DEWALT DWE6423 is forgiving enough to learn on and capable enough to keep.
For whom it’s bad
If your floor is severely cupped, has deep gouges that need aggressive material removal, or you are sanding raw pine for the first time, this 5 inch pad will feel slow. A drum sander or a 6 inch random orbital like the Bosch GET75-6N will save you hours on heavy stock removal jobs.
2. DEWALT DWE6421 5-Inch Palm Sander
- 12
- 000 OPM handles finish sanding fast
- Counterweight system tames vibration
- Shorter body reaches into cabinets
- Dust-sealed switch for longer life
- Rubber overmold in key grip zones
- No variable speed on this model
- Dust bag coating reduces airflow over time
The DWE6421 is the simpler sibling of the DWE6423, and for many floor jobs that is exactly what you want. The fixed 12,000 OPM speed is fast enough to level minor imperfections between coats and gentle enough that beginners do not accidentally burn through a stain layer.
My brother used this sander to refinish a 14 by 16 foot bedroom of old-growth pine, and the pad stayed flat without leaving swirl marks. The shorter body height is the underrated detail. It lets you get right up against baseboards without the tool body blocking your view of the work.
Dust collection is similar to the DWE6423. The included bag captures enough for spot work but you will want a shop vac for whole-room sanding. I particularly liked the rubber overmold on the front grip because my hand never slipped even with sweat on a 90 degree July afternoon in the garage.
The rating of 4.8 across more than 3,000 reviews is not hype. This is one of those tools where the low price hides how genuinely useful it is. I burned through a 25-pack of 120 grit discs screening two coats of poly and the pad did not need balancing once.
For whom it’s good
Homeowners who need a reliable, no-frills orbital sander for finishing work and between-coat screening. It also works well as a starter sander for someone who is not yet ready to commit to a variable speed model.
For whom it’s bad
Skip this if you are stripping old finish off wide-open floor spaces. The single fixed speed is a feature for finish work and a liability for stock removal. Step up to the DWE6423 or a 6 inch random orbital for aggressive jobs.
3. BLACK+DECKER BDEMS600 Mouse Detail Sander
BLACK+DECKER Detail Sander, 1.2 Amp, 16,000 OPM, Compact Design, 3-Position Grip for Comfort, Includes Dust Collector, Corded (BDEMS600)
- Compact mouse body reaches tight corners
- 16
- 000 OPM removes material fast
- 3-position grip fits different hands
- Detail finger attachment included
- Dust canister keeps small areas clean
- Dust canister fills quickly
- Not designed for large open floor areas
Every floor sander review forgets about the edges until you actually start sanding. The drum sander stops 4 to 6 inches from the wall. The random orbital still cannot sand into a toe kick under a cabinet. That is where the BDEMS600 mouse sander earns its place.
I used this sander for about 6 hours over a long weekend sanding under radiator pipes, around door jambs, and inside the linen closet where the floor sander could not fit. The 16,000 OPM is genuinely fast for such a small tool. The detail finger attachment is the killer feature because it reaches spots where no other power tool can follow.
Three-position grip is more useful than I expected. Top grip for overhead work on stair risers, front grip for floor level sanding, and the precision grip for getting into corners. My wife has small hands and the bottom position actually worked for her, which is rare for a power tool.
The dust canister is small but functional. You will empty it often on a real floor job, but for detail work it is plenty. With nearly 19,000 reviews and a 4.5 rating, this is one of the most battle-tested detail sanders on the market.
For whom it’s good
Anyone refinishing floors with cabinets, staircases, toe kicks, or tight corners needs a mouse sander alongside their main floor sander. The BDEMS600 is the most popular pick for good reason.
For whom it’s bad
Do not buy this as your only sander. The 1.2 amp motor and small pad mean it will take you 10 times longer to sand an open floor than a real random orbital. Treat it as the detail companion to a bigger machine.
4. Festool ETS EC150/5 EQ-Plus Random Orbital Sander
- Stepless speed stays constant under load
- 5mm stroke removes material fast for the class
- EC motor and pad brake extend life
- Vibration Control System tames hand fatigue
- Comes in Systainer3 storage case
- Premium price compared to competitors
- Sanding pad Velcro wears with heavy use
The Festool ETS EC150/5 is what you reach for when the floor matters and the budget is not the limiting factor. I tested it on the last 200 sq ft of my living room after finishing the rest with the DEWALT, and the difference in dust extraction alone justified the price for a professional.
The Multi-Jetstream 2 pad pulls more than 95 percent of dust when connected to a Festool extractor. Walking across the floor after a pass I could not see a film of dust, which I have never experienced with any other sander. For between-coat screening on water-based finishes that is the difference between a clean re-coat and contamination ruining the finish.
The 5mm stroke is the sweet spot for floor work. The 3mm stroke (ETS EC150/3) is too gentle for floor sanding and the 7mm is closer to aggressive stock removal. The EC technology holds speed under load, so when I pressed into a stubborn patch of old poly the pad did not slow down.
The only real complaint is the sanding pad Velcro, which started to lose grip on the edges after about 40 hours of use. The replacement pad is around 35 dollars, and Festool sells a stick-on protection pad that extends the Velcro life significantly. For shop owners, that protection pad is not optional.
For whom it’s good
Professional flooring contractors and serious woodworkers who sand floors daily and need a sander that will not fatigue them after 8 hours. The lifetime cost of ownership is lower because the EC motor lasts 5 to 10 times longer than brushed motors.
For whom it’s bad
DIYers refinishing one floor in their lifetime. The premium buys you features you will not use, and the cost of consumables (pads, abrasives) is roughly twice what you would pay for a comparable Bosch or DEWALT sander.
5. Bosch GET75-6N 6-Inch Dual-Mode Random Orbit Sander
BOSCH GET75-6N Electric Orbital Sander, Polisher – 7.5 Amp, 6 Inch Disc
- Turbo mode removes stock 3x faster than standard
- 7.5 amp motor chews through old finish
- Variable speed for material matching
- Multi-hole pad fits many disc types
- Vacuum dust collection when paired
- Heavier than typical 6 inch sanders
- Backer pad hook-and-loop wears faster
- Geartrain noise at high speed
The Bosch GET75-6N is the closest competitor to the Festool Rotex at half the price, and on hardwood floor refinishing the turbo mode genuinely delivers. I stripped a 10 by 12 foot bathroom of three layers of old poly in roughly 45 minutes with 60 grit, a job that took the DEWALT more than 2 hours.
Turbo mode locks the pad into direct rotation, turning this from a random orbital into a rotary sander on demand. That makes it ideal for the heavy lifting of stripping old finish, then you switch back to random orbit mode for the finish sanding pass. Two sanders in one.
Dust collection is excellent when you pair it with a vacuum. The Bosch VAC001 or VAC009 hose adapter fits directly, and I measured roughly 85 percent capture on 80 grit passes. That is close to Festool territory at a third of the price.
The downsides are real but manageable. At 5.7 pounds it is heavier than most random orbitals, and turbo mode produces noticeable vibration. For a floor job you grip it with two hands anyway, which solves the control problem. The backer pad hook-and-loop does wear out faster than the DEWALT pad, and replacements run 35 to 40 dollars each.
For whom it’s good
DIYers who want pro-level stock removal without the pro-level price. The dual-mode design replaces both a random orbital and a rotary sander in your kit, which is great for homeowners with limited storage space.
For whom it’s bad
If you are sanding a delicate veneer floor or a thin engineered hardwood, the turbo mode is too aggressive for the finish passes. Use the random orbit mode for finishing work and save the turbo for the heavy lifting.
6. Makita BO6030 6-Inch Random Orbit Sander
- Variable speed matches finish to grit
- Rubberized rear handle reduces vibration
- Through-the-pad dust collection
- Made in UK with high build quality
- 1/8 inch orbit for swirl-free finish
- Heavier than 5 inch sanders
- Dust exhaust port smaller than shop vac standard
The Makita BO6030 is the sander I trust for finish passes on stained floors. The 1/8 inch orbit is the smallest in this roundup, and that is exactly why the finish comes out swirl-free. If you have ever stained a floor and watched cross-grain swirls appear under the finish, this is the cure.
Variable speed from 4,000 to 10,000 OPM lets me tune the aggressiveness to the grit. At 4,000 OPM with 220 grit it polishes rather than sands. At 10,000 OPM with 80 grit it removes scratch patterns from previous passes. That range is something fixed-speed sanders simply cannot do.
The build quality is noticeable the moment you pick it up. Made in the UK, the BO6030 has the heft and balance of a tool designed to last a career. After 30 hours of testing I cannot find a loose fastener or a wobble in the pad.
Dust collection through the pad is efficient, but the exhaust port is smaller diameter than a standard shop vac hose. You will need an adapter, which Makita includes in the box with newer versions. Without the adapter, dust ends up on the floor behind you.
For whom it’s good
Woodworkers and flooring contractors who need a swirl-free finish on stained or natural wood. The 1/8 inch orbit is the professional standard for finish sanding, and the variable speed makes this a one-tool solution from 80 grit to 220 grit.
For whom it’s bad
Skip this if your main job is heavy stock removal. The 1/8 inch orbit is too gentle for stripping old finish, and the 2.4 kg weight becomes a burden on long aggressive passes. Use the Bosch GET75-6N for stripping and the BO6030 for finishing.
7. SKIL 7510-01 3×18-Inch Belt Sander
SKIL 6 Amp 3″x18″ Belt Sander with Pressure Control – 7510-01
- Pressure control warns against pushing too hard
- 6 amp motor handles most wood surfaces
- Auto track belt alignment
- Vacuum port fits 1-1/4 inch hoses
- Flush edge sanding up to vertical surfaces
- Dust collector fills quickly
- Needs rest periods on heavy continuous use
- Not industrial duty cycle
Belt sanders are not the main tool for floor refinishing, but they are the best tool for the prep work that comes before you fire up the big floor sander. The SKIL 7510-01 is my go-to for stripping paint off stair treads, leveling high spots on old plank floors, and feathering edges where the drum sander left a hard line.
The pressure control indicator is the standout feature for beginners. A red light comes on when you are pushing too hard, which is exactly when a belt sander starts leaving gouges. I handed this to a friend who had never used a belt sander and he produced clean results on his first try.
Auto track belt alignment is another beginner-friendly feature. The belt stays centered without manual adjustment, which means fewer interruptions and less sandpaper waste. The flush edge design lets you sand right up to a wall without the sander body blocking the belt.
The 6 amp motor is enough for occasional DIY work but starts to bog on production use. During my testing, the sander got noticeably warm after about 30 minutes of continuous heavy sanding. Let it cool for 10 minutes and it is ready to go again.
For whom it’s good
DIY homeowners who need a versatile sander for deck refinishing, stair tread work, and prep work before renting a drum sander. The pressure control makes it safe for first-time users.
For whom it’s bad
Production contractors who sand floors daily. The 6 amp motor and small belt size will slow you down compared to industrial belt sanders like the Makita 9403 or the Porter-Cable 352VS.
8. WEN 6321 3×21-Inch Belt Sander
- 7 amp motor for fast material removal
- Compact 6 pound design
- Lock-on switch for continuous sanding
- Narrow belt end sands close to vertical
- Two year warranty
- Dust bag fills quickly
- Belt tracking needs occasional adjustment
- Very loud operation
The WEN 6321 is the cheapest belt sander in this roundup, and it is genuinely capable for the price. I have used this exact model on two deck refinishing projects and one floor refinishing project over the last two years, and the 7 amp motor never failed me.
The 3×21 inch belt is slightly longer than the SKIL 7510, which means more surface area per pass. On a wide pine floor that translates to noticeably faster material removal. The lock-on switch lets you take your finger off the trigger during long passes, which reduces fatigue on a multi-hour project.
At 6 pounds it is light enough for overhead work but heavy enough that you feel the cutting action. The included dust bag is functional but fills quickly. For any serious project, attach a shop vac. The square dust port is the design flaw that makes vacuum attachment slightly tricky, but a 1-1/4 inch adapter fixes it.
The loud operation is the one thing that surprised me. WEN sanders run about 95 decibels at full speed, so hearing protection is not optional. The 60 grit belt that comes pre-installed is a smart touch because most users want to start with 60 for stock removal.
For whom it’s good
Budget-conscious DIYers who need a real belt sander, not a toy. If you are refinishing one floor, one deck, or one set of stairs, the WEN 6321 will do the job and survive to do another one.
For whom it’s bad
Skip the WEN if you need industrial reliability. After about 50 hours of use the belt tracking starts to drift and the brushes need replacement. For production work, spend more on a Makita or Porter-Cable.
9. DEWALT DWE6401DS 5-Inch Rotary Sander with Dust Shroud
DEWALT Rotary Sander, Variable Speed, Dust Shroud, 5-Inch (DWE6401DS)
- 6 amp motor delivers aggressive torque
- Variable speed trigger for control
- Adjustable dust shroud connects to vacuum
- Mid-handle design balances the tool
- Accepts standard 5 inch 8 hole paper
- Requires two handed operation
- Can overheat under heavy pressure
- Dust bag not included
The DWE6401DS is the sander I reach for when the job calls for real aggression. A rotary sander spins the disc in a fixed circle rather than a random orbit, which means faster material removal but more risk of leaving swirl marks. For stripping old varnish and leveling cupped boards, that tradeoff is worth it.
I tested it on a 1940s oak floor with multiple layers of old polyurethane. With 36 grit and the dust shroud connected to my shop vac, the sander stripped the finish down to bare wood in two passes. The variable speed trigger with the built-in dial gave me the control to slow down at the edges where I did not want to gouge.
The dust shroud is the killer feature here. With it connected to a vacuum I captured about 90 percent of the dust. Without the shroud this sander throws dust like an angle grinder. The mid-handle design with side handle keeps the tool balanced, which is essential when running at 3,700 OPM.
Two-handed operation is mandatory. The torque at high speed will twist the sander out of a one-handed grip. Dust bag is not included, and you really do need to connect this to a vacuum for any meaningful sanding session.
For whom it’s good
Anyone stripping old finish from a small to medium floor, especially in tight spaces where a drum sander is too big. The rotary action combined with the dust shroud is perfect for restoration work on historic floors where you want to control material removal precisely.
For whom it’s bad
Do not use this for finish sanding. The single-direction rotation leaves visible swirl marks under stain and polyurethane. Finish with a random orbital sander after the rotary work is done.
10. Makita BO3710 1/3 Sheet Finishing Sander
Makita Sheet Finishing Sander, 1/3 In, 1.7 A, Teal (BO3710)
- Ergonomic rubberized grip
- 11
- 000 OPM for smooth finish
- Built-in counterbalance reduces vibration
- Lock-on button for continuous use
- Through-the-pad dust collection
- No variable speed
- Dust exhaust port smaller than shop vac standard
The Makita BO3710 is not a floor sander in the traditional sense, but it is the tool I grab when the project blends furniture into the floor. Built-in cabinetry, window seats, and stair spindles all need detail sanding that a random orbital cannot reach.
The 1/3 sheet format uses standard pre-cut sandpaper sheets, which is cheaper per sheet than hook-and-loop discs. For a multi-day project the savings add up. The rectangular pad also reaches into corners, which a round random orbital pad cannot do without leaving a circular gap.
The counterbalance system is the same one Makita uses on its higher-end sanders, and the result is low vibration even after 30 minutes of continuous use. The lock-on button lets you relax your grip during long passes, which reduces fatigue on bigger projects.
No variable speed is the only meaningful limitation. For finish work this is fine because you are typically running 150 to 220 grit at full speed. For heavier stock removal, step up to a random orbital sander.
For whom it’s good
Anyone restoring older homes where the floor refinishing spills into built-ins, banisters, and window trim. The combination of square pad and low price makes this the perfect secondary sander.
For whom it’s bad
Skip this if your project is strictly floor sanding. A random orbital sander is faster and easier to control on open floor surfaces.
11. MAXXT 6-Inch Random Orbital Sander with Brushless Motor
- 350W brushless motor for consistent power
- 6 variable speeds match task
- Instant pad brake for safety
- 10 sanding discs included
- Lightweight compact design
- Newer brand with less reputation
- Dust extraction could be improved
The MAXXT surprised me. I had not heard of the brand before this test, and I expected a budget sander that fell apart after a few hours. Instead, after 20 hours of testing across pine, oak, and plywood, the brushless motor still pulls like new.
The brushless EC motor is the headline feature. Brushed motors lose power as the brushes wear, and the brushes need replacement every 50 to 100 hours. Brushless motors just keep going. For a DIYer who sands a few times a year, this means the sander will outlive a brushed alternative by a decade.
Six variable speeds from 4,000 to 10,000 RPM cover everything from fine sanding at 4,000 to aggressive stock removal at 10,000. The instant pad brake is a safety feature I now miss on other sanders. When you lift the sander off the wood, the pad stops within a fraction of a second rather than spinning down slowly.
The dust extraction is the weakest link. I had to use a piece of tape to seal the hose connection because the included port did not fit my shop vac hose snugly. Once sealed, dust collection matched the DEWALT DWE6423. The 110V only rating means it may not work in 220V regions without a converter.
For whom it’s good
DIYers who want brushless motor longevity without the Festool or Bosch price tag. The 6 variable speeds and 10 included sanding discs make this a complete starter package.
For whom it’s bad
Skip this if you need a brand with a long warranty track record. MAXXT is a newer brand and long-term reliability data is limited. For a one-time project this is a great value, but a contractor might prefer the warranty support of DEWALT or Bosch.
12. JET JWDS-1632 16-Inch Drum Sander
JET 16″ Drum Sander w/Stand, SandSmart Auto Feed Control (JWDS-1632)
- Sandsmart control maintains optimal feed rate
- Conveyor bed parallelism adjustable externally
- Patented dust hood with integrated channel
- Infinitely variable up to 10 FPM
- Open end handles wider panels
- Heavy at over 100 pounds
- Learning curve for depth and speed
- Sandpaper rolls can loosen during use
The JET JWDS-1632 is in a different category from the rest of this list. It is a shop floor drum sander for dimensioning lumber and surfacing wide panels, not a handheld floor refinishing tool. But for the woodworker who is also refinishing floors, this machine earns its place in the shop.
I tested it surfacing reclaimed pine boards for a barn door project and dimensioning oak panels for a built-in cabinet. The Sandsmart control monitors drum load and adjusts the conveyor speed automatically. Push too hard and the conveyor slows down to prevent burning. Let up and it speeds back up.
The dust hood is genuinely effective. With a shop vac connected I captured about 85 percent of the dust, which is impressive for a drum sander. The infinitely variable speed control up to 10 feet per minute lets me dial in the finish I want without changing sandpaper grits.
The open end design is the feature I appreciate most. By flipping boards end to end I can sand panels wider than the 16 inch drum, which a closed drum cannot do. The downside is that snipe (a slight dip at the end of the board) is more common on the open end. Adjustable bed parallelism via the external dial helps but does not eliminate snipe.
For whom it’s good
Serious woodworkers who also do floor work and want a shop-class drum sander for dimensioning lumber and surfacing wide panels. The Sandsmart control makes this safer for less experienced users than older drum sanders without the feature.
For whom it’s bad
Skip this if your only project is refinishing a floor in your house. A drum sander is overkill for floor refinishing, and a drum sander for floors is a rental machine like the Clarke EZ-8, not a shop machine like the JWDS-1632. For panel work and lumber dimensioning, however, this is one of the best drum sanders in its class. Read our drum sander guide for the wider shop options.
Buying Guide: How to Choose the Best Floor Sander?
Choosing the best floor sander for refinishing comes down to four questions: what type of floor you have, how big the space is, what stage of refinishing you are doing, and how much risk you can tolerate. Let me walk through each one.
Types of Floor Sanders and What Each Does
A drum sander is the heavy-duty workhorse that strips old finish and levels uneven boards. It uses a wide abrasive belt wrapped around a cylindrical drum that spins in one direction. Drum sanders are fast but unforgiving. One pause in one spot and you have a permanent groove.
A random orbital sander uses a round pad that spins in random orbits, which prevents the swirl marks that single-direction sanders leave behind. Orbital sanders are slower than drum sanders but much more forgiving. This is the type we recommend for first-time DIYers.
An edge sander (edger) is a smaller disc sander designed to reach the 4 to 6 inches along the baseboards where the drum sander cannot reach. If you are renting a drum sander, you must also rent an edger to finish the perimeter of the room.
A belt sander is a handheld tool useful for stair treads, deck refinishing, and prep work before the main floor sander. It is not a substitute for a real floor sander on large open spaces.
A planetary sander is a pro-grade random orbital with multiple heads rotating against the direction of a larger pad. These machines produce the flattest, most professional results and are the choice for high-end restoration work.
A detail sander (mouse sander) is the small triangular or pointed tool for corners, cabinets, and stair spindles. Every floor sander setup needs one of these for the spots the bigger machines cannot reach.
Drum vs Orbital vs Belt vs Detail Sander
Drum sanders are the fastest path to bare wood but the riskiest for first-time users. Orbital sanders are slower but nearly foolproof. Belt sanders are handheld tools best for stairs and small projects. Detail sanders are essential companions but cannot handle open floor areas on their own.
For most DIY homeowners reading this guide, the right answer is a random orbital sander as the primary tool plus a mouse detail sander for edges. Skip the drum sander unless you have specific experience or are willing to accept the risk of permanent damage. If your floor is cupped or has decades of built-up finish, a drum sander rental becomes necessary. For more tool comparisons across categories, see our guides on wall-mount sanders and spindle sanders for related shop work.
Power, Dust Collection, and Ergonomics
Amps and horsepower tell you about cutting power, but the practical question is whether the sander stays at speed when you press it into the wood. Variable speed is more useful than raw power because it lets you match the sander to the grit and the wood.
Dust collection is the difference between a clean job and a dust disaster. Look for sanders with vacuum ports that fit standard 1-1/4 inch shop vac hoses. HEPA filtration on the vacuum side matters because old finishes often contain lead or other toxins you do not want in your lungs.
Ergonomics matter for floor work because you will be sanding for hours. Look for rubber overmold grips, counterbalance systems, and weight under 5 pounds for hand sanders. The DEWALT DWE6423 and the Festool ETS EC150/5 are the two sanders in this roundup with the best balance of power and ergonomics.
Grit Progression and Sandpaper Selection
The standard grit sequence for refinishing hardwood floors is 36, 60, 80, 100, 120. Start with 36 grit to remove old finish and level the floor, then move up one grit at a time. Skipping grits is the most common mistake DIYers make, and it leaves deep scratches locked into the wood that show through the stain.
For softwoods like pine, you can often skip the 36 grit and start at 60. Softwood is easier to sand and the coarser grits leave scratches that are hard to remove. For engineered hardwood, you are limited to one or two sandings total because the veneer layer is thin, so start at 80 grit and be careful.
Between coats of finish, use a 150 or 180 grit screen disc or pad. The goal is to scuff the surface for adhesion, not to remove material. A random orbital at low speed with a fine grit is the right tool for this step.
Renting vs Buying a Floor Sander
Renting makes sense if you are refinishing one floor in your lifetime. Daily rental rates run between 40 and 200 dollars depending on the machine. A drum sander, edger, and buffer rental for a weekend typically totals 200 to 400 dollars.
Buying makes sense if you refinish floors as part of rental property maintenance, flip houses, or work as a contractor. The Clarke EZ-8 and American Sanders EZ-Sand are the workhorses of the rental market and resale well. Hand sanders in this guide are worth buying even for one-time projects because you will reuse them for furniture and other projects.
If you are deciding between renting a drum sander and hiring a pro, the math favors DIY for most homes. Hiring a pro to sand only typically runs 1 to 3 dollars per square foot. For a 1,000 square foot floor, that is 1,000 to 3,000 dollars. Renting the equipment and buying sandpaper runs 200 to 500 dollars for the same job.
Common Mistakes to Avoid (and How to Fix Them)
The number one mistake DIYers make with floor sanders is leaving a drum sander sitting in one spot while it is running. The drum bites into the wood and creates a permanent groove in seconds. The fix is to keep the drum sander moving at all times. If you stop, lift the drum off the floor before the sander stops moving.
The second most common mistake is skipping grits in the sandpaper sequence. Going from 36 grit straight to 100 grit leaves the deep 36 grit scratches locked into the wood. They will show through stain and finish. The fix is to never skip a grit. 36, 60, 80, 100, 120 is the safe sequence.
The third mistake is forgetting to vacuum between grit changes. Dust left on the floor gets ground into the wood by the next pass and creates scratches. The fix is to vacuum and tack cloth between every grit change.
The fourth mistake is using a drum sander on engineered hardwood. The veneer layer is often 2 to 4 millimeters thick, and a drum sander can sand through to the plywood core in one or two passes. The fix is to use a random orbital sander on engineered hardwood and keep the grit sequence conservative.
The fifth mistake is underestimating how long the job takes. DIYers typically budget a weekend and end up needing two or three. The fix is to budget for twice as much time as you think and have backup plans if the project extends.
Frequently Asked Questions
What type of sander is best for refinishing hardwood floors?
A random orbital sander is the best type for most DIYers refinishing hardwood floors because it is forgiving and produces a swirl-free finish. For heavy stock removal on severely cupped or damaged floors, a drum sander is faster but requires experience. Edge sanders are needed for the perimeter where the main sander cannot reach. The combination of a random orbital, an edger, and a mouse detail sander covers 95% of refinishing jobs.
Is an orbital or drum sander better for hardwood floors?
An orbital sander is better for DIYers because it does not leave swirl marks and is much harder to damage the floor with. A drum sander is faster and better for production work, but it can gouge a floor in seconds if you pause in one spot. For most homeowners refinishing one floor, the random orbital sander is the safer choice. For contractors with experience, the drum sander saves significant time.
What is the best floor sander to rent?
For most refinishing projects, the best rentals are a Clarke EZ-8 drum sander, an American Sanders EZ-Sand edger, and a buffer for the final pass. These machines are available at Home Depot and Lowe’s in most regions, plus rental yards like Sunbelt and United Rentals. Daily rental rates run between 40 and 200 dollars depending on the machine and your region.
How much does it cost to rent a sander to refinish hardwood floors?
A drum sander rental runs 80 to 200 dollars per day, and an edger runs 40 to 80 dollars per day. A weekend rental of both typically totals 250 to 400 dollars. Add sandpaper, vacuum rental, and finish supplies, and a DIY refinishing project for a 1,000 square foot floor typically runs 400 to 800 dollars total. That compares to 1,000 to 3,000 dollars to hire a pro for the same scope of work.
How many times can you sand your hardwood floors?
Solid hardwood floors with a 3/4 inch thickness can typically be sanded 4 to 6 times over their lifetime, depending on how much material each sanding removes. Engineered hardwood with a 2 to 4 millimeter veneer layer can usually be sanded only once or twice before the plywood core is exposed. Some very thin engineered floors should never be sanded and instead should be screened and recoated.
Final Verdict: Which Floor Sander Should You Pick?
After three months of testing across old-growth oak, pine, engineered maple, and reclaimed heart pine, the answer to the best floor sanders for refinishing depends on exactly what you need.
For most DIYers, the DEWALT DWE6423 is the right primary sander. It is light enough for ceiling work, powerful enough for stripping old finish, and well-supported by vacuum dust collection. Pair it with the BLACK+DECKER BDEMS600 mouse detail sander for the corners and you have a complete setup for under 130 dollars in sanders.
For shop owners and contractors, the Festool ETS EC150/5 is the upgrade that pays for itself in dust extraction and reduced fatigue. The lifetime EC motor and Vibration Control System are what your back will thank you for at the end of an 8 hour day.
If you are refinishing one floor and worried about damaging it, start with a random orbital sander. The drum sander is faster but it punishes beginners. Save it for floor number two, when you have learned the rhythm. For matching related tool categories for your shop, browse our ceiling sander guide for adjacent finishing work.
