The workshop vacuum that also cleans spills
A workshop wet & dry vacuum handles site dust, concrete sludge, workshop shavings, water leaks, and the weekly car interior. For UK trade use, it has to pair with power tools for dust extraction as well as stand on its own for cleanup.
This guide covers the best wet and dry vacuums for UK trade and DIY use in 2026: M-class dust-extractor rated models for regulated work, plus general-purpose wet/dry vacs for workshop and site.
What to look for
- M-class vs L-class vs domestic: M-class is required for HSE-regulated fine dust (silica, hardwood). L-class is coarser dust. Domestic vacs are neither and won't handle trade fines safely.
- Auto power tool linking: A vacuum that turns on when the connected tool's trigger is pulled saves battery, extends life, and stops you forgetting.
- Capacity: 20–30 l for most site use. 40 l+ for regular water extraction or workshop use.
- Suction (CFM / airflow): 200–250 CFM is the trade sweet spot. Higher = better dust capture from high-volume tools (routers, tile saws).
- Filter cleaning: Self-cleaning filters (Festool CT, Bosch GAS-35) save hours of maintenance. Manual-clean filters clog in heavy dust.

~£140–£185Best for: Workshop / DIY / occasional trade
Karcher's WD6 is a domestic-plus wet/dry vac for workshop and light trade use. 30 l, 1300 W, auto filter-cleaning. Not M-class or L-class, so not for regulated dust, but excellent value for garage, workshop, and car-cleaning use. Auto-start socket for power tools.
View on Amazon →Buying advice
For regulated fine-dust work (silica, MDF, hardwood), M-class is not optional — HSE rules require it and workers have won compensation claims against employers who skipped it. Buy the Festool CT 36 AC or Bosch GAS 35 M AFC.
For general site cleanup without regulatory dust concerns, Karcher WD6 or Makita DVC155LZ cordless is enough.
Pair the vacuum with an antistatic dust-extraction hose matched to your power tools' dust ports. Festool's 27/32 mm hoses fit most sander/router ports; Bosch has equivalent. A loose-fit hose is 80% effective at best.
Frequently asked questions
What is M-class and do I need it?
M-class is an EU dust-class rating for fine dust (silica from cutting concrete/brick, MDF particles, hardwood). HSE regulations require M-class extractors when working with these materials. For general site cleanup, an L-class or unrated vacuum is acceptable.
Can I use a wet/dry vac as a power-tool dust extractor?
Technically yes, but an unrated workshop vac won't capture enough of the fines to protect your lungs during long use. For pairing with sanders, routers, and saws, use an L-class minimum — ideally M-class with auto-start.
How often should I replace the filter?
Manual-clean filters clog fast in dust — check every 20–30 minutes of heavy use. Self-cleaning filter vacs (Festool CT, Bosch AFC) back-pulse automatically every 15–30 seconds and can go months between replacements. Budget one or two replacement filters per year for daily trade use.
