Rank #6 in Best Orbital Sander 2026: 10 Models Ranked — and the Amp Figures That Don't Add Up
RYOBI 18V ONE+ 125 mm Random Orbit Sander, Bare
Price and rating as shown on Amazon when we collected them. Both change.
The RYOBI 18V ONE+ 125mm Random Orbit Sander sits at number six in this guide. It is £67.30 as a bare tool — the listing's own wording is "Battery & Charger Excluded" — and it carries 4.7 out of 5 from 834 ratings, with 80 of the 100 ratings shown in the breakdown at five stars.
Its odd number is "Amperage Capacity: 5 Amps". The same listing describes the sander as Battery Powered at 18 Volts and sells it without a battery or charger, so the 5 Amps sits in a box that, on a cordless tool, can only be describing a battery pack rather than anything the motor draws. There is no wattage figure anywhere on the listing to check it against, so unlike the Bosch entries in this guide the arithmetic is not even possible here: the only power number RYOBI gives is 18 Volts. Read "5 Amps" as a description of a battery that is not in the box. Everything below is taken from the Amazon listing, not from any testing of our own.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“The RYOBI 18V ONE+ 125mm Random Orbit Sander is fantastic. Super powerful for a cordless and gives a really smooth, swirl-free finish. Lightweight, comfortable grip and very low vibration. No cable getting in the way makes jobs so much quicker. Uses my existing ONE+ batteries too. Highly recommend!”
Verified purchase“I have used this sander for two large hardwood gates and some furniture.It's a great tool, the dust bag was not a problem and worked remarkably well at catching the dust. I shake out the dust spoil then hoover the bag regularly too keep goid air flow. This will stop the bag blowing off.The other thing I like is it's not as noisy as my old wired one”

Questions people ask
Does it come with a battery and charger?
No. The listing sells the RYOBI 18V ONE+ 125mm Random Orbit Sander as a bare tool — "Battery & Charger Excluded" — and the box contains 1x Random Orbit Sander, 3x sanding sheets (80/120/240 grit) and a dust bag.
What does the 5 Amps figure refer to?
It appears in the "Amperage Capacity" field of a sander the same listing calls Battery Powered at 18 Volts, sold without a battery. On a cordless tool that field can only describe a battery pack, and no wattage figure is given anywhere on the listing to compare it with.
How fast does the RYOBI sander run?
The listing gives a "Maximum Rotational Speed" of 20,000 RPM, while its item highlight reads "20000opm". With a 2.5 mm orbital motion and "random orbit action", the figure is orbits per minute rather than disc rotations.
What sanding sheets does it take?
The sander uses a 125 millimetre disc with quick fit hook and loop attachment. Three sheets are included, at 80, 120 and 240 grit, and the listing gives a Grit Rating of 240.
Does it collect dust?
Yes. RYOBI lists a built in dust extraction system and a dust bag among the included components.
What is the rating and how many people rated it?
The listing shows 4.7 out of 5 from 834 ratings. The breakdown displayed accounts for 100 ratings, of which 80 are five-star, 13 are four-star, 5 are three-star and one each at two and one star.
