Brushless Random Orbital Sanders: 5 Things to Know
The short answer: a brushless random orbital sander gives you more power, longer battery life and a motor that won't wear out, and it's worth the premium if you sand more than a couple of times a month. The catch is price: brushless cordless sanders run from about £75 bare up to £300 with a battery. Before you spend, these five things decide whether the upgrade actually pays off for the work you do.
1. Brushless means no carbon brushes, and that changes everything
A brushed motor pushes current through carbon blocks that press against a spinning commutator. Those blocks wear down, shed dust and generate heat the harder you work the tool. A brushless motor drops the mechanical contact entirely: an electronic controller drives the coils, so there's nothing to wear and far less heat to manage.
In practice that means a brushless sander holds its speed better under load, runs cooler on long sessions and lasts several times longer between failures. It's the same reason every serious brand has moved its professional line over. The Makita DBO180Z is a textbook example: the brushless LXT motor keeps an 11,000 OPM orbit steady even when you lean into oak, and the pad brake stops it skating when you set it down.
2. You pay a real premium, so decide if you'll actually use it
The cheapest way into brushless is a bare tool on a platform you already own. The Einhell TP-RS 18/32 Li BL-Solo sits at about £75 with its 3.2mm orbit and 24,000 strokes per minute, which makes it the budget brushless pick for Power X-Change owners. The DeWalt DCW210N-XJ is the step up at roughly £116, adding variable speed and noticeably lower vibration.
If you sand once a month to refresh a shelf or a tabletop, a decent brushed sander still does the job and costs less. If you're prepping furniture, doors or multiple projects a year, the brushless premium buys real time back, because it removes material faster and doesn't fade when the work gets tough.
3. The battery is half the price, so count it before comparing
Bare tool prices look attractive until you remember you need a battery and charger. That's why the kits matter. The Makita DBO180Z with a 5Ah battery lands around £170 complete, and the Bosch GEX18V-5B15 kit bundles the brushless sander with a 4Ah CORE18V battery for about £296.
Here's the honest comparison: the DeWalt DCW210N-XJ at £116 bare only makes sense if you already own XR batteries. If you're starting from nothing, the Makita kit at £170 is the cheaper complete solution, and the Bosch kit buys the pro-grade speed control and CORE battery tech. Work out your platform first, then the sander price.
4. Cordless sanders are battery hogs, and brushless helps
Sanding is continuous load, which is the worst case for any battery. A brushed sander can flatten a 2Ah pack in well under twenty minutes of real work. A brushless motor runs more efficiently across its speed range, which is why the same size battery goes noticeably further.
That efficiency is also why the brushless models keep their power as the battery drains. A brushed tool fades as voltage drops; a brushless controller keeps output flat until the pack is nearly empty, so your final passes match your first. For bigger jobs, grab a second battery or hook the sander to dust extraction and plan around charge cycles.
5. Match the orbit and speed to the job, not the badge
Not all brushless sanders feel the same. Orbit size controls how aggressive the cut: a 2.8mm orbit like the Makita DBO180Z is a fine all-rounder for stock removal and finishing, while a 3.2mm orbit like the Einhell TP-RS 18/32 leans toward faster material removal. Variable speed, which the DeWalt DCW210N-XJ and Bosch GEX18V-5B15 both have, lets you slow down for plastics, fillers and final finishing without leaving swirl marks.
For most UK home workshops, a 125mm pad with a brushless motor and variable speed is the sweet spot. It handles paint stripping, edge work and fine finishing with one pad size, and 125mm discs are cheap everywhere.

Final Verdict
Buy brushless if you sand more than a couple of times a month, because the motor efficiency and longevity pay for the premium quickly. The DeWalt DCW210N-XJ at £116 is the pick for most home workshops, the Einhell TP-RS 18/32 Li BL-Solo at £75 is the value entry, the Makita DBO180Z kit at £170 is the best complete package, and the Bosch GEX18V-5B15 kit at £296 is the one for pros. Check your battery platform first, and you'll buy the right one the first time.
