Rotex vs random orbital sander: which one do you need?
In this guide
The verdict by job
| The job | Pick | Why |
|---|---|---|
| Sanding furniture, cabinets and trim between coats | Random orbital | Light, fine finish |
| Stripping old paint or varnish off a big surface | Rotex (geared mode) | Forced rotation cuts faster |
| Flattening a glued-up tabletop or rough panel | Rotex (geared mode) | Aggressive stock removal |
| Final sanding before stain or paint | Either, in random orbit mode | Random orbit gives the finer scratch |
| Polishing paint or a clear coat | Rotex (geared mode) with a polishing pad | Built to polish as well as sand |
| Tight spots and small parts | Small random orbital or a Rotex RO 90 with the delta pad | A big pad won't reach |

What makes a Rotex different?
A random orbital sander's pad spins freely while it also moves in tiny loops. That mix keeps the scratches from lining up, which is why it leaves a fine finish.
A Rotex adds a second mode. Festool says its RO 150 does coarse sanding in ROTEX mode, fine sanding in random orbit (eccentric) mode, and polishing with the ROTEX rotary motion. In ROTEX mode, gears force the pad to turn instead of letting it spin freely.
Bosch makes a similar tool. Its GET65-5N has a standard random orbit mode for normal removal and fine finishing, plus a Turbo mode with direct-drive rotation. Bosch says Turbo removes 3x the stock of the standard mode.
Spec comparison
| Model | Type | Pad | Stroke or orbit | Power | Speed |
|---|---|---|---|---|---|
| Festool RO 150 FEQ-Plus | Gear-driven (Rotex) | 6 in (150 mm) | 3/16 in (5 mm) | 720 W | 320–660 rpm geared; 3,300–6,800 rpm random orbit |
| Festool RO 125 FEQ-Plus | Gear-driven (Rotex) | 125 mm (about 5 in) | 3.6 mm | 500 W | 300–600 geared; 3,000–6,000 random orbit |
| Festool RO 90 DX FEQ-Plus | Gear-driven (Rotex), delta pad option | 90 mm | 3 mm | 400 W | 260–520 geared; 3,500–7,000 random orbit |
| Bosch GET65-5N | Dual mode (Turbo) | 5 in | 0.09 in (2.25 mm) orbit radius | 6.5 A | 3,300–7,800 OPM |
| Bosch ROS20VSC | Random orbital | 5 in | 3/32 in (2.5 mm) orbit | 2.5 A | 7,500–12,000 OPM |
| Makita BO5041 | Random orbital | 4-7/8 in pad, 5 in discs | 1/8 in orbit | 3 A | 4,000–12,000 OPM |
| DeWalt DWE6423 | Random orbital | 5 in | Not listed | 3 A | 8,000–12,000 OPM |
Makers measure stroke and orbit in different ways, so compare within a brand when you can. Weight matters too: Festool lists the RO 150 FEQ-Plus at 5.95 lb (2.7 kg), while Bosch lists the ROS20VSC at 3.5 lb and Makita lists the BO5041 at 3.1 lb.
The differences in depth
Finish quality
For the last grit before stain or paint, use random orbit mode on either tool. Festool itself assigns fine sanding to the random orbit mode. If you see little loops after sanding, see orbital sander swirl marks.
Polishing
None of the random orbital sanders in our table list polishing as a mode. A Rotex does. Festool lists polishing as one of the RO 150's three jobs and sells polishing pads for it.
Motor and power source
The Rotex models in our table are corded; Festool lists the RO 150 for 120 V with a 13 ft (4 m) cable. Random orbital sanders also come in battery versions, such as DeWalt's 20V DCW210.
The trade-offs are like those for saws: see corded vs cordless miter saw. The DCW210 uses a brushless motor. Our guide to brushed vs brushless tools explains what that changes.
Discs and pads
The random orbital sanders in our table take 5-in discs, and the Rotex RO 150 takes 6-in (150 mm) discs. The hole pattern has to match your pad for dust pickup to work. See sanding disc hole patterns, and pick grits with the sandpaper grit chart.
Dust extraction: not optional
Every sander in the table has a dust port. Bosch's ROS20VSC has a filter canister and a hose adapter.
DeWalt's DWE6423 has a dust bag and a port that fits its extractors. Makita's BO5041 has through-the-pad dust pickup. Festool's RO 150 has a 1-1/16 in (27 mm) extraction port.
Who should buy which
Buy a random orbital sander if:
- You sand furniture, cabinets, doors and trim.
- You want one light sander that's easy to use with one hand.
- You mostly sand between coats, not strip old finishes.
Buy a Rotex (or another gear-driven sander) if:
- You strip old finishes off big surfaces often.
- You flatten tabletops, panels or boat parts.
- You polish paint or clear coats and want one tool for both jobs.

Example sanders
The details below are from the makers' own spec pages. Our removal test above used the RO 150 and the Bosch ROS20VSC; we haven't tested the others.
- Festool RO 150 FEQ-Plus. 6-in Rotex: geared and random orbit modes, 5 mm stroke, polishing.
- Festool RO 90 DX FEQ-Plus. Small Rotex with a tool-free swap to a triangular delta pad.
- Bosch GET65-5N. 5-in dual-mode sander with Turbo.
- Makita BO5041. 5-in random orbital with a 1/8-in orbit. More from the brand on our Makita page.
- DeWalt DWE6423. 5-in variable-speed random orbital. See our DeWalt page.

What you'll need
- Sander with a dust port: Random orbital or gear-driven
- Discs that match your pad size and hole pattern: 5 in or 6 in, check the holes
- Shop vacuum or dust extractor with a hose adapter: Better than the bag alone
- Respirator or dust mask, safety glasses, hearing protection: For any power sanding
- Polishing pads: Only for a sander with a polishing mode
Key takeaways
- A Rotex is Festool's gear-driven sander. It switches between a geared rotary mode and a normal random orbit mode.
- Festool's RO 150 has a 5 mm (3/16 in) stroke and draws 720 W. Bosch's 5-in ROS20VSC random orbital has a 3/32 in orbit and draws 2.5 A.
- Use the geared mode for coarse sanding and polishing, and the random orbit mode for fine sanding.
- Bosch's GET65-5N is another gear-driven option; Bosch says its Turbo mode removes 3x the stock of its standard mode.
- Hook up dust extraction either way. Wood dust can cause respiratory problems, and old paint may contain lead.
Questions people ask
What is a Rotex sander?
Rotex is Festool's name for its gear-driven sanders. The pad can be driven by gears in a forced rotary motion for coarse sanding and polishing, or left free to spin in a random orbit for fine sanding. You switch modes on the tool.
Is a rotary sander the same as an orbital sander?
No. A rotary tool spins the pad in a circle, which cuts fast but can leave swirls. A random orbital sander spins and orbits at the same time for a finer finish. A Rotex can do both.
Is a Rotex worth it for a DIYer?
Only if you remove a lot of finish or polish often. For sanding furniture, trim or cabinets, a random orbital sander does the job and weighs less.
What's the difference between an orbital and a random orbital sander?
An orbital (sheet or palm) sander moves a square pad in small circles and takes cut-up sheets. A random orbital sander uses a round pad that also spins, so its scratches don't line up in a pattern. Our random orbital vs palm sander guide covers it in full.
Can I polish a car with a Rotex?
Festool sells the Rotex as a sander and polisher, with polishing pads for it. Use the rotary mode with a polishing pad and follow the paint and polish maker's directions.

Change log: Nov 6, 2026: Rewritten from the 2024 archive post. Added Festool, Bosch, Makita and DeWalt spec data, a mode-by-job verdict, dust and lead safety. Removed unsupported claims (orbital sanders leave no swirl marks; Rotex moves in an 'elliptical' motion).
