Have the Karcher 120 with all the gadgets. Give it a couple of years & many of the 120 bars will be missing. Not good for hard use im afraid. Also have a Wickes 160 bar very good alround tool but extras are just that extra but its worth it. You wont get anything to last at that £100 price level its false ecconomy measured over 5 years.
Oops just realised im in the Concours area. Was thinking of a Power washer for the garden etc

. Mine would probably blow the car away.
I use a Bucket & Sponge on the car.
Sorry Rod
