Kärcher WD 3 V-17/4/20 review

The entry workshop vacuum: seventeen litres, a cartridge filter, and nothing that will not be missed.

The bottom line The right first workshop vacuum: cheap, honest, and unremarkable in the way a tool should be.

The WD 3 is the machine most workshops start with: 17 litres, 1 000 W and a cartridge filter that handles dust and water without being swapped.

What a wet and dry vacuum is actually for

Not carpets. It is for what a household vacuum must never meet — standing water, plaster dust, sawdust, broken glass, the contents of a blocked sink trap, the gravel in a car footwell. A domestic vacuum bag turns to paste on the first litre of water; this machine is built around that fact.

The two metres of hose

The specification that shapes daily use is the hose, and two metres is short. In a car it is fine. Across a workshop floor it means the machine follows you every couple of minutes, which is exactly when tools get pulled over. The step up to a WD 4 P or WD 5 P buys hose, cable and a power socket for a sander — a bigger practical difference than the drum size.

The bag question

Fleece bags cost more than paper and hold several times as much before the suction fades, because they filter across their whole surface instead of clogging at the inlet. On plaster or ash — which this machine should not be used for anyway — the difference is not marginal.

Availability

One reference across all six Amazon stores, including the United States.

What we like, and what we don't

Strengths

  • Cartridge filter stays in place for wet pick-up on this generation — no filter swap for water
  • Seventeen litres is enough for a car interior, a workshop floor or a blocked sink
  • One reference on all six Amazon stores

Compromises

  • Two metres of hose: you move the machine constantly
  • No power take-off socket for tools, unlike the P models
  • Plastic drum — light, and less tolerant of being dropped than steel

Questions people actually ask

Do I need to remove the filter to vacuum water?

On this generation Kärcher's cartridge filter is designed to stay fitted for both wet and dry work, which removes the classic wet-vac mistake of soaking a paper element. Check the manual for your exact model before the first wet job — on older and cheaper machines a foam filter must be fitted instead, and getting that wrong destroys the filter in one use.

Is 1 000 W enough?

For a household machine, yes. Wattage describes what the motor consumes, not what the machine picks up — airflow and suction do that, and neither is published here. What actually limits this machine is the two-metre hose and the 17-litre drum, not its motor.
