My Karcher suddenly raced and the water stopped although the pump was still running. dismantled the outer case and the works are all sealed up in a nylon case, so no way of getting in, so binned it and bought a new one at a third off at Wickes, well, it's rubbish, no power to the spray, should have returned it but will not buy Karcher again. Why did the old one have more power than the latest model.

Johnno, March 2017

Their web site shows 20 models ranging in price from £570 down to £80. The specifications of each will differ.

Your question...

Why did the old one have more power than the latest model.

Is difficult to answer because you do not describe the two models - the 2020B has a 1300W motor.

Perhaps you paid more for the old one...

Good Luck..., March 2017
