A cordless vacuum is one of those tools you resist buying for years, then wonder how you ever managed without. No lead to trip over, no hunting for a socket in a stripped-out room, and no more brushing dust into a pan while it drifts straight back onto the floor. For anyone who cares about leaving a clean job – and about their own lungs – a good cordless vac has quietly become as essential as the drill.
This guide is for UK trades choosing a cordless vacuum in 2026. Every price is an approximate UK street price including VAT and moves with battery deals and promotions, so treat them as a guide rather than gospel. We cover L-class site vacs, compact grab-and-go units, wet and dry options, and which one actually earns its place in the van.
Our quick verdict
If you are already on Makita LXT, the twin-18V DVC157L is the one to beat for serious dust – proper L-class filtration, AWS auto-start so it fires up when your saw does, and enough capacity for a real day of work. It is not cheap at around GBP 500-560 bare, but you are not buying into a new platform. Milwaukee users get the same story with the M18 Fuel 23L L-class vac, which brings VACLINK wireless start and a huge tank for bigger strip-outs.
For second-fix carpenters and anyone who wants a lighter unit for quick clean-downs, the Bosch GAS 18V-10 L is the sensible pick. And if you only need occasional site tidy-up and do not want to spend big, a compact single-battery vac or the mains-powered Numatic George (around GBP 269-289) still does the job for a fraction of the money.
How to choose a cordless vacuum
Dust class – L, M or H
This is the number that actually matters. L-class handles general nuisance dust – wood, plaster, most site muck. M-class is required for hardwood dust, MDF and concrete dust, which is where HSE takes an interest, and it filters far finer particles. H-class is for the nasty stuff – silica, lead, asbestos-adjacent work. Most cordless vacs are L-class; if you cut a lot of MDF or masonry, look specifically for an M-class rating rather than assuming L will do. Your lungs do not grow back.
Capacity and run-time
A 6-8 litre compact vac is fine for second fix and quick tidy-ups but fills fast on a strip-out. A 15-23 litre unit means fewer trips to the skip but is heavier and bulkier in the van. Run-time depends on your battery – a 5.0Ah pack will give you a solid stint, but if you run the vac hard all day, factor in a spare battery or a mains-capable model.
Auto-start and wireless triggering
The best feature on modern site vacs is auto-start: the vacuum senses when you pull the trigger on a connected tool and switches on automatically, then runs on for a second or two to clear the hose. Makita calls it AWS, Milwaukee calls it ONE-KEY / VACLINK. Once you have used it with a track saw or sander you will never go back to reaching for a switch with your hands full.
Corded, cordless or both
Cordless wins for freedom and speed – grab it, clean, done. But a big cordless vac drinks batteries, and if you are extracting off a sander for an hour it makes sense to have a mains option. Plenty of trades run a cordless for clean-downs and keep a corded M-class extractor for tool-connected work. Decide by how you actually work, not by what looks best on the shelf.

The picks in detail
Best overall for Makita users – Makita DVC157L
If your van runs on Makita LXT, the DVC157L is the obvious buy. It uses two 18V batteries in series for 36V of suction, carries a proper L-class filter, and includes AWS so it auto-starts off a compatible saw or sander. The 15-litre tank strikes a good balance between capacity and portability, and the build is the usual Makita tank. At roughly GBP 500-560 as a bare unit it is a serious spend, but you are not buying another platform – just add it to the batteries you already own. For a working chippy or shopfitter, it is the one that does everything.
Best for big strip-outs – Milwaukee M18 Fuel 23L L-class
Milwaukee users get a genuine rival in the M18 F2VC23L. The 23-litre tank swallows a serious amount before you need to empty it, VACLINK gives you wireless auto-start and remote control, and the brushless Fuel motor keeps the airflow up as the battery drains. It runs on dual M18 batteries for extended run-time. At around GBP 320-380 bare it undercuts the Makita on price while offering more capacity, so if you are already red it is a strong shout – especially for demolition and refit work where you are hoovering rubble all day.
Best for second fix – Bosch GAS 18V-10 L
Not everyone needs a 15-litre monster. For a second-fix carpenter or a kitchen fitter doing clean-downs between rooms, the Bosch GAS 18V-10 L is light, quick to grab and still L-class rated. It takes a standard Bosch Professional 18V battery, has a rotational airflow design that keeps suction consistent, and is small enough to live in the van without eating space. At around GBP 150-190 bare it is the sensible pick if you want tidy clean-ups rather than heavy extraction.
Best for fine dust – DeWalt DCV586M
If you cut MDF, hardwood or masonry regularly, you want M-class, and the DeWalt DCV586M delivers it on the 54V FlexVolt platform. M-class filtration captures the fine particles that L-class lets through, which matters for both your health and HSE compliance. It runs the big FlexVolt batteries you may already own for your grinder or table saw, and the auto-start works with connected tools. Around GBP 300-360 bare, it is the one to buy if your dust is the dangerous kind rather than just untidy.
Best compact wet/dry – Milwaukee M18 Packout 7L
The M18FPOVCL Packout vac is a clever bit of kit: a 7-litre L-class wet and dry vacuum that clips straight onto a Packout stack, so it travels as part of your storage rather than as a separate lump. It handles spills and damp muck as well as dry dust, and from around GBP 216 bare it is the cheapest way into a proper brand cordless vac. Capacity is modest, so it is a clean-up tool rather than an all-day extractor, but for plumbers and sparks it is ideal.
Best budget all-rounder – Numatic George GVE370
Not cordless, but worth including because it is the vacuum a lot of trades actually reach for. The Numatic George is a wet, dry and carpet-extraction machine in one tub, built like the Henry it is related to, and at around GBP 269-289 it undercuts every cordless site vac here. There is a lead to manage, but the capacity, reliability and sheer versatility make it the value champion for anyone who does not need cordless freedom. Buy one for the workshop or the van and it will outlast several power tools.
Looking after your cordless vacuum
A vacuum is only as good as its filter. Tap it out or wash it (if the filter is washable) regularly – a clogged filter kills suction and makes the motor work harder. Empty the tank before it is completely full, especially with heavy plaster or brick dust that compacts and blocks airflow. Keep a spare filter in the van, check the hose for splits and blockages, and never run an L-class vac on M-class dust and assume you are covered. Look after it and a good vac will see out years of site abuse.
Frequently asked questions
Is a cordless vacuum powerful enough for site work?
For clean-up and tool-connected extraction, yes – modern 36V and 54V units pull plenty of air. For hours of continuous heavy extraction you may prefer a mains M-class extractor to avoid draining batteries, but for the way most trades work, a good cordless vac is more than capable.
Do I need L-class or M-class?
L-class covers general site dust – wood, plaster, general muck. If you regularly cut MDF, hardwood or masonry, you need M-class, which filters the fine particles that damage your lungs and which HSE expects you to control. When in doubt, spend the extra on M-class.
Can I use it as a dust extractor off my saw?
Yes, if it has an auto-start feature and the right hose adaptor. Makita AWS and Milwaukee VACLINK let the vac fire up automatically when you trigger a connected tool. Check hose diameter and cuff compatibility with your saw or sander before buying.
Wet and dry or dry only?
A wet-and-dry unit is more versatile – it deals with spills, damp cuts and site water as well as dust. If you only ever suck up dry dust, a dry-only vac is fine and often cheaper, but most trades find the wet capability earns its keep sooner or later.
