6 reviews for Karcher K4 Power Control Home Pressure Washer

Great item
Just tried it on my block paving area. Looks like its working brilliantly
I was delighted with the service and advice
The K4 seems to be able to cope with the jobs that I have tried it on and is more flexible than my old K2. What stood out was the helpfulness of the staff, for advice and guidance so far very happy
Karcher K4 pressure Washer
Purchase experience was positive overall. The first one delivered had a crack in the case. This was returned and quickly replaced with a minimum of fuss. Not used this one yet but have used one before and it was excellent. All parts were well packaged in the box. It was easy to put together. I am looking forward to attacking my patio next weekend.
