Compare power, control, and cost to find the right hardwood floor sander for your refinishing job.
Refinishing a hardwood floor comes down to one big equipment decision: drum sander or orbital sander. Drum sanders cut fast and handle heavy stripping, but they punish mistakes with visible gouges. Orbital sanders move slower but forgive beginners and leave a smoother, more even finish. Both are available to rent by the day or week, so you don't need to buy a machine you'll use once or twice a year. Here's how to pick the right one for your floor, your skill level, and your budget.
Common Questions About Renting a Floor Sander
- Should I use a drum sander or orbital sander?
- Use a drum sander if you're stripping thick finish, deep scratches, or old varnish down to bare wood on a solid hardwood floor. Use an orbital sander if you're a first-time DIYer, refinishing engineered or softer wood, or doing a lighter maintenance sand between coats. Drum sanders remove material 3 to 4 times faster but leave gouges quickly if you hesitate or tilt the machine. Orbital sanders take longer per pass but almost never gouge, which makes them the safer rental for someone who hasn't run a floor sander before.
- What type of sander is best for sanding floors?
- For most whole-floor refinishing jobs, a drum sander like this 8 inch drum floor sander with dust bag gets the job done fastest on solid hardwood. For homeowners nervous about gouging or working on thinner wood veneers, an orbital sander such as this Clarke OBS-18DC orbital floor sander is the better rental. Professional flooring contractors often rent both: drum for the main field of the floor and an edger for the perimeter.
- Is a drum or orbital floor sander better for decks?
- Neither is really designed for decks, and this is a common point of confusion in forum discussions. Drum and orbital floor sanders are built for interior hardwood floors and struggle with the gaps, fasteners, and uneven boards typical of a deck. For deck refinishing, most rental customers do better with a belt sander, disc sander, or a dedicated deck sander rather than a drum or orbital floor unit. If you're set on using a floor sander outdoors, an orbital model is the lower-risk choice since it won't dig into soft, weathered deck boards the way a drum sander can.
- What is the difference between a floor sander and a drum sander?
- "Floor sander" is the general category, and a drum sander is one specific type of floor sander. The other main type is the orbital (or orbital/square-buff) floor sander. Both fall under the umbrella of floor refinishing equipment, but they use completely different mechanisms: a drum sander spins a cylindrical drum wrapped in sandpaper at high speed, while an orbital sander moves a flat sanding pad in small circular orbits across the floor. When people ask about "floor sander vs drum sander," they're usually really asking drum vs orbital.
- How much does it cost to rent a drum or orbital floor sander per day?
- Drum floor sanders typically rent for $50 to $75 per day or $150 to $220 per week, depending on the model and your local provider. Orbital floor sanders usually run slightly less, around $45 to $65 per day, since they're lighter and require less maintenance. Most listings on Rntr show local daily and weekly rates side by side, so you can compare pickup pricing in your area before booking.
- Do I need a deposit to rent a floor sander?
- Yes, most providers require a refundable deposit ranging from $50 to $200 for a drum or orbital floor sander, on top of the rental fee. The deposit is usually returned within a few days after the equipment is checked in undamaged. Some rental shops also require a valid ID and a credit card hold instead of a cash deposit, so it's worth confirming the specific policy on the listing before you drive over to pick up the machine.
- Should I rent an edger along with my floor sander?
- Almost always, yes. A drum or orbital floor sander can't reach tight corners, closets, or edges along baseboards, so most refinishing jobs pair the main sander with a smaller edging sander. A 7 inch hardwood floor edger handles that perimeter work and blends into the main floor's finish. Renting both together in one trip saves you a second visit to the rental counter.
Drum Floor Sanders: Fast, Aggressive, and Built for Bare Wood
The tradeoff for speed is control. Because the drum spins so aggressively, stopping or tilting it even briefly while it's running will gouge the wood, sometimes permanently. Drum sanders also require changing grit progressively (coarse to fine) across multiple passes, which takes practice to get an even result across an entire room. If you've never handled one, plan on a slower first day and consider practicing on a closet floor before tackling the main living room.
Orbital Floor Sanders: Safer, Smoother, and Easier to Control
A unit like this Clarke OBS-18DC orbital floor sander or this orbital floor sander available in Pelican Rapids is a common pick for homeowners tackling their first floor refinishing project. Expect to spend more time per pass than you would with a drum sander, and expect a slightly less dramatic transformation if the floor has heavy damage or thick old finish. For light-to-moderate refinishing, though, orbital sanders often produce a smoother final surface with fewer visible pass lines.
Matching the Sander to Your Project
For decks, patios, and outdoor wood surfaces, neither drum nor orbital floor sanders are the right tool category. those machines are built for flat interior hardwood and don't handle deck board gaps, screws, or weathered exterior wood well. If you're refinishing a deck, look for a dedicated deck or belt sander instead, and reserve your drum or orbital rental for indoor floor sanding guide projects. Whichever machine you choose, pair it with a 7 inch hardwood floor edger to finish the edges and corners the main sander can't reach.
Drum vs Orbital Floor Sander: Side-by-Side Comparison
Both machines fall under the same floor refinishing equipment category, but they perform very differently on the job. Here's how a typical rented drum floor sander stacks up against an orbital model.
| Feature | Drum Floor Sander | Orbital Floor Sander |
|---|---|---|
| Best for | Heavy stripping, thick old finish, deep scratches | Light refinishing, first-time users, veneer floors |
| Sanding speed | Fast, removes material quickly | Slower, more gradual removal |
| Learning curve | Steep, requires practice | Beginner-friendly |
| Gouging risk | High if the machine stops or tilts | Very low |
| Best surface | Solid hardwood, bare wood stripping | Engineered wood, light recoats |
| Typical daily rate | $50 to $75 per day | $45 to $65 per day |
| Typical weekly rate | $150 to $220 per week | $140 to $200 per week |
| Deposit range | $75 to $200 | $50 to $150 |
| Dust containment | Bag-attached, moderate control | Bag-attached, generally cleaner |
