The 10 Best Cordless Random Orbital Sanders
Battery-powered 5-inch random orbit sanders ranked from live Amazon data — swirl-free finishes with no cord to drag around.
A cordless random orbital sander trades a little runtime for the freedom to sand a car hood, a stair rail, or a ladder-top window frame without hunting for an outlet. This list covers bare tools for buyers already on a battery platform (DeWalt, Milwaukee, Makita, Craftsman, Metabo HPT) alongside complete kits that include a battery and charger, sorted by what varies most: variable speed, dust collection, and whether it ships ready to use.
Where the deals are
The tools ranked here come from DEWALT, Milwaukee, Makita, BLACK+DECKER, CRAFTSMAN, AVID POWER, WORKPRO, Metabo HPT, and RYOBI. Prices on these brands move week to

4.7
13,908 reviews
Score 92/100
The best-selling cordless sander on Amazon by a wide margin — nearly 14,000 reviews at 4.7 stars. It's the bare-tool version of the kit above: same brushless motor, same 8,000–12,000 OPM dial, same dust-sealed switch. The obvious buy if you already own a DEWALT 20V battery.

Best Overall
DEWALT
DEWALT 20V MAX Random Orbital Sander Kit (DCW210P1)
4.7
472 reviews
Score 85/100
The most complete package on this list. It's the same brushless DCW210B tool below, but sold with a 5.0Ah battery and charger so it's ready to sand out of the box. The variable-speed dial runs 8,000 to 12,000 OPM, and the sander attaches directly to a DEWALT dust collector or the included locking dust bag.

Milwaukee
Milwaukee Electric Tools 2648-20 M18 Random Orbit Sander
4.7
3,591 reviews
Score 77/100
The pick for anyone already on Milwaukee's M18 platform. A powerful motor and a 7,000–12,000 OPM variable-speed dial let it remove more material per battery charge, with up to 35 minutes of runtime on a 3.0Ah pack.

4.8
2,842 reviews
Score 77/100
The highest-rated sander on this list at 4.8 stars across 2,842 reviews. Three fixed speed settings (7,000/9,500/11,000 OPM) switch with a one-touch control, a pad brake cuts down free-spin for a cleaner finish, and Makita rates it for up to 40 minutes of runtime per charge.

BLACK+DECKER 20V MAX Orbital Sander, Cordless, 12,000 OPM, Battery and Charger Included (BDCRO20C)
4.4
2,599 reviews
Score 73/100
A complete kit — sander, 1.5Ah battery, charger, and two sandpaper sheets — for under $90. A fixed 12,000 OPM and a compact body keep muscle fatigue down on longer jobs, and the battery works across BLACK+DECKER's 20V MAX lineup.

CRAFTSMAN V20 Orbital Sander, Cordless, 12,000 OPM, Bare Tool Only (CMCW220B)
4.7
1,489 reviews
Score 73/100
The cheapest bare tool from a major brand here, and a fair trade if you don't need a speed dial. A fixed 12,000 OPM, a low-profile body, and a dust-sealed switch cover most sanding jobs, with a port that connects to a 1-1/4" shop-vac hose.

- Dust port fits a 1-1/4" shop-vac hose, not just the bag
Cons

- Tool only — battery and charger sold separately

Ties Makita for the highest rating here at 4.8 stars, with the longest warranty on the list — 5 years. Six speed settings plus an electric brake for faster stops, at 2.6 lb it's also the lightest tool in this lineup, and it ships with two sanding pads and a vacuum adaptor.

RYOBI 18V ONE+ 5" Random Orbit Sander Cordless
4.5
131 reviews
Score 62/100
The pick for anyone already invested in RYOBI's ONE+ battery system, which spans hundreds of tools. Multiple grip zones and a rubber-membrane rocker switch keep it comfortable to hold, and the dust port accepts both 1-1/4" and 1-7/8" shop-vac hoses.

Buyer's guide
Bare tool or a complete kit?
If you already own batteries and a charger for a brand — DeWalt, Milwaukee, Makita, RYOBI, CRAFTSMAN, Metabo HPT — buy the bare tool; it's cheaper and adds one more tool to a battery system you already have. If you're starting from scratch, a kit like the AVID POWER or BLACK+DECKER that bundles a battery and charger is the better value than buying a bare tool and a battery separately.
Do I need variable speed?
Variable speed lets you slow the pad down for delicate work like veneer or paint prep, where full speed can burn or gouge, and speed it up for fast material removal. A single-speed tool like the CRAFTSMAN or BLACK+DECKER is fine for general use; if you sand a mix of materials, pay for the dial.
How much runtime should I expect?
A cordless random orbital sander typically runs 20 to 40 minutes on a mid-size battery (2.0–3.0Ah), depending on speed and pressure. If you're sanding all day, keep a second battery charging, or consider a corded sander instead — see our corded random orbital sander picks.
Dust bag or vacuum port?
A cloth dust bag is convenient but fills fast and lets fine dust through. A tool with a hose port — like the DEWALT, CRAFTSMAN, RYOBI, or Metabo HPT picks here — connects to a shop vac for far better dust collection, which matters more indoors than outside.
Does battery voltage (18V vs 20V) matter?
Not directly for sanding power. "20V MAX" and "18V" are largely marketing conventions — DeWalt and Craftsman rate their packs at their maximum unloaded voltage (20V), while Makita and Milwaukee use the nominal voltage (18V) for the same class of battery. What matters is staying within one brand's battery platform, not comparing the number on the box across brands.
Is a 5-inch pad standard on cordless sanders too?
Yes. Every sander on this list uses a 5-inch, 8-hole hook-and-loop pad, the same size and hole pattern as corded random orbital sanders, so sandpaper is interchangeable between the two.
