Pros and cons

According to our construction vacuum expert
  • Thanks to the 5m power cord, you can work farther away from the socket.
  • You can collect the dirt in the dust bag or the boiler, so you can decide what's best for you.
  • The filter is washable, so it lasts longer.
  • You can't adjust the power suction of the construction vacuum to your job.

Description

The Kärcher WD 4 V-20/5/22 is part of the 4 series, so it has a larger dust container than the 3 series, namely 20L. This makes this vacuum more suitable for the regular handyman. You can use the model both with and without dust bag. Are you going to work with wet dirt? We recommend not using a bag, so you can clean the device more easily afterwards. Another advantage is that the cable of the 4 series is 1m longer than the 3-series. This gives you even more freedom of movement while working and you don't have to switch outlets as quickly. The included filter is washable and easy to clean after use. This way, you save on costs.

Perfect device for the hobby handyman

  • Strong suction power
  • Accessories always at hand on the device
  • Very manoeuvrable
  • No blower function

Before I bought this device I borrowed a multi-purpose vacuum cleaner from a friend of a much higher price range. The Karcher surprised me by delivering the same (perhaps even better) suction power for a third of the price of the more expensive unit. However, don't expect professional quality; for the heavier work you will have to invest more. Are you a hobby handyman like me? Then this Kärcher will do just fine. In fairness I have to add (so far) that I have not done any 'wet' jobs with the device yet.

  • long cord
  • great suction
  • very nice filter system
  • somewhat short suction rod

Really a very good powerful water and vacuum cleaner! With an acceptable noise level. I was immediately very happy with this purchase. Much better and much more solid than my old one. However, it had a long hose and that is very easy.

  • Excellent and fast extraction of water in the cellar with 3 mm of water daily
  • HOW happy am I with this
  • No downside

This Kärcher has an easy-to-attach dust bag, which does not have to take up too much space when vacuuming dry, like a Bosch. I only now have experience with wet vacuuming in the basement, and what a positive experience >>Great!!!
