How we picked

We did not run tests of our own. Grades come from documentation, warranty statements and retailer prices read on October 21, 2026. Five criteria carried the weight.

Weight and height before anything else. A random orbit sander is held in one hand, often at arm's length on a vertical surface or above shoulder height on a door frame.

Published weight therefore outranks published power here, which is the reverse of how we grade a saw.

Speed range, not top speed. All three reach at least 10,000 orbits per minute, which is plenty for stock removal. The useful difference is the low end, because finish coats, veneer and edges need a slower pad.

Only two of the three publish a range at all.

Dust collection as the box ships. A sander makes the finest dust of any common power tool. We counted what arrives with the tool, not what the maker sells separately, and we noted every adapter you still have to buy.

Consumables and the pad. Paper and the hook-and-loop backing pad are the recurring costs. We checked that each maker publishes a replacement pad part number and sells paper that matches its hole pattern.

Warranty terms as a timeline. Years matter, but so do free-service periods and money-back windows. We read the terms printed on each product page rather than the headline number.

The same rubric runs through our first power tools for homeowners guide and our cordless circular saw guide.

Best overall: DeWalt DCW210B

The lightest and lowest body here, with the only brushless motor the three makers claim.

Quick specs: 5 in. 8-hole hook-and-loop pad, 8,000 to 12,000 OPM variable-speed dial, brushless motor, 1.9 lb, 8.8 x 6.4 x 5.8 in., locking dust bag, dust-sealed switch, 20V MAX bare tool.

Warranty is 3 years limited with 1 year free service and a 90-day satisfaction guarantee, per DeWalt's product page checked October 21, 2026.

Strengths: at 1.9 lb and 5.8 in. high it is the lightest and lowest of the three on listed figures, and DeWalt markets the low profile as keeping your hand close to the work. The dust bag locks on with one hand.

The port fits DeWalt's DWV010 and DWV012 extractors directly. DeWalt links its own 8-hole paper, DW4310 at 100 grit and DW4309 at 80 grit, as related accessories.

Limits: DeWalt publishes no price, no orbit diameter and no runtime figure for this tool. We checked the specification block and the opening pages of the manual and did not find them.

A generic 1-1/4 in. shop-vac hose needs the DWV9000 Universal Quick Connector, sold separately. The tool ships without a battery or charger.

Why it sits at #1: it costs the same $149.00 bare as the Milwaukee at Zoro while weighing 0.8 lb less, and weight is what your forearm reports after an hour of sanding a tabletop.

Best dust collection and warranty: Milwaukee 2648-20

The most completely documented sander of the three, and the only one that arrives ready to meet a shop vac.

Quick specs: 5 in. hook-and-loop pad, 3/32 in. orbit, 7,000 to 12,000 OPM variable-speed dial, up to 35 minutes on an M18 REDLITHIUM XC3.0 pack, 2.7 lb, 10.5 x 4.92 x 5.74 in.

In the box are a dust canister with filter, universal and extension hose adapters and two 80-grit sheets, under a 5-year limited warranty, per Milwaukee's product page checked October 21, 2026.

Strengths: the 7,000 OPM floor is the lowest here, which is the setting that matters for scuffing between coats and for veneer. It is the only one of the three with a published runtime and the only one whose box includes a hose adapter.

Five years is two more than either rival. Milwaukee publishes the operator's manual and the parts list on the product page.

Limits: 2.7 lb and 10.5 in. long make it the biggest tool here. Milwaukee's specification table reads FUEL: No and Motor Type: Not Applicable, so we do not describe it as brushless even though its rival is.

Milwaukee's page shows no price, and the runtime claim is tied to a pack sold separately.

Why it sits at #2: it wins on paper in four places and loses on the one number you feel. For a buyer who sands indoors with a generic vacuum, or who keeps tools a decade, the order flips and this is #1.

Best value starting from zero: Ryobi PCL406B

A kit with a battery and charger for less than either rival's bare tool.

Quick specs: 5 in. hook-and-loop pad, 3/32 in. orbit, single listed speed of 10,000 OPM, dust port for 1-1/4 and 1-7/8 in. hoses, a claimed 40 percent vibration reduction, 3-year limited warranty.

Prices are $59.97 bare and $124.00 for the PCL406K1 kit with a 4Ah battery and charger, per ryobitools.com checked October 21, 2026.

Strengths: the price is the whole argument, and it is a strong one. By our arithmetic the bare tool is $89.03 cheaper than either pro-brand rival at Zoro, and the kit with a battery and charger still undercuts both bare tools by $25.00.

The dust port takes two common hose sizes with no adapter to buy. The published orbit of 3/32 in. matches Milwaukee's. Ryobi sells a replacement backer pad, A21BP01, at $16.97 and a seven-piece paper pack, A21701, at $6.47.

Limits: one speed, so no slow setting for finish work. Ryobi publishes no weight or dimensions, so you cannot compare hand feel on paper. The 40 percent vibration claim has no stated baseline.

No dust bag or canister is listed among the included items, which makes a vacuum hose effectively mandatory indoors.

Why it sits at #3: the missing dial and the missing figures cost it points, not the price. For a few projects a year it is the sensible buy, especially if you already own the Ryobi ONE+ drill or the ONE+ HP circular saw.

Also compared (did not make the cut)

Four more sanders were read and left off the list, each for a documented reason.

• Ryobi ONE+ HP PBLSD01B: Ryobi's brushless sander, listed at $129.00 bare in its search results on October 21, 2026, with a kit at the same figure. We have not reviewed it, and Ryobi's listing did not give us a speed range to compare, so we will not rank it
• Ryobi RS290G corded: $69.00 on ryobitools.com the same day. A cord never runs out of charge, which suits long bench sessions near an outlet, but it rules out ladder and yard work
• DeWalt DCW200B quarter-sheet sander: a sheet sander, not a random orbit sander, so it leaves straight-line scratches on cross grain. DeWalt's page showed 3.7 stars from 20 reviews on October 21, 2026
• DeWalt DCE800B drywall sander: a different tool for a different job, and the worst-rated sander on DeWalt's own listing at 2.8 stars from 13 reviews the same day

OPM, orbit diameter and what the numbers actually change

Two numbers decide how a random orbit sander behaves, and only one of them appears on every page.

Orbits per minute is how fast the pad moves. All three sanders reach at least 10,000 OPM, so none of them is slow. The difference is the floor: Milwaukee 7,000, DeWalt 8,000, Ryobi fixed at 10,000.

A slower pad removes less material per pass, which is what you want when you are scuffing a cured coat, sanding veneer thinner than 1/32 in., or working within an inch of a crisp edge you do not want rounded over.

Orbit diameter is how far off centre the pad swings. Milwaukee and Ryobi both publish 3/32 in. DeWalt publishes none, and we could not find one in the specification block or the opening pages of its manual, so the scratch pattern comparison stays incomplete.

A bigger orbit cuts faster and leaves a coarser pattern; a smaller one is slower and finer. Within this group the two published figures are identical, so grit choice will matter far more than the tool.

The practical sequence for most furniture is 80 grit to flatten, 120 to clean up, 180 or 220 before finish. Changing grit in order beats changing sanders.

How to choose a random orbit sander

Four questions settle almost every purchase.

Which batteries do you already own? All three tools here are sold bare, and a second platform for one $149 tool is never the better deal. If your charger holds yellow or red packs, buy the matching sander.

Our DeWalt 20V vs Ryobi ONE+ comparison and Milwaukee M18 vs DeWalt 20V comparison cover the platform decision itself.

Where will the dust go? This is the question most homeowners skip. Indoors, a sander needs a vacuum hose, not a bag.

The Milwaukee connects to a generic shop-vac hose out of the box, the Ryobi port fits two common hose sizes, and the DeWalt needs the DWV9000 connector unless you own a DeWalt extractor.

How long is a typical session? Twenty minutes on a shelf forgives a heavy tool. Four hours on a dining table does not, and that is where the DeWalt's 1.9 lb listing earns its place.

How often will you sand? A few projects a year points at the Ryobi kit at $124.00. Regular refinishing points at a variable-speed dial, which only the DeWalt and the Milwaukee have.

Whatever you buy, budget for paper. A sander with worn 120 grit is slower than a sharp 80, and you will go through more sheets than you expect.

For corners and profiles a 5 in. pad cannot reach, the Dremel 4300 rotary tool takes small sanding drums and flap wheels.

Dust is the part most homeowners underestimate

Sanding produces the finest airborne dust of any common DIY task, and a cloth bag catches only part of it.

Milwaukee's operator's manual for the 2648-20, read October 21, 2026, asks for eye protection marked to comply with ANSI Z87.1 and, in dusty situations, appropriate respiratory protection or an OSHA-compliant dust extraction solution. That advice applies to all three sanders.

The manual also says to remove the battery before changing paper or emptying the canister, which is worth making a habit on any cordless tool.

If the surface is painted and the house predates 1978, check for lead before you start and follow EPA lead-safe practices if it is present. A random orbit sander is one of the worst tools to use on lead paint without containment.

Download the manual for whichever sander you buy and read its safety section before the first use. Each maker publishes it on the product page.

Bottom line

Buy the DeWalt DCW210B if you want the best sander here on balance, or if your charger already holds 20V MAX packs. It is the lightest, the lowest and the only brushless one, at $149.00 bare at Zoro in October 2026.

Buy the Milwaukee 2648-20 if you own M18 packs, if you sand indoors with a generic shop vac, or if a 5-year warranty and a 7,000 OPM low setting are worth more to you than 0.8 lb.

Buy the Ryobi PCL406K1 kit at $124.00 if you own no cordless batteries and sand a few times a year. It gives up the dial and the published figures, not the job.

All three use 5 in. hook-and-loop paper, so none of them locks you into expensive consumables. The battery already on your shelf should outvote everything above.
