Despite saying I'd rather cut off my arm than by another one, SWMBO bought me one for Christmas having seen me pitch my old one in to the council skip. So today being a bank holiday, what better time to clean all the patio !! However, the whole time I was using it, it sort of hunted as it was running, like stop start stop start, even though I had the trigger firmly held on. Any one know why ?

Low water pressure?

Mine sometimes does that when I first start - and I put it down to low pressure until it's built up a flow

The last one I had did that all the time. It still worked ok but I think there was a problem with the pump. It could be low wster pressure, as said, but if you rule that out I would be inclined to pursue the warranty. John

This used to happen on my old one. My hozelock end on my hose had a valve in it to stop water coming out, except when you had an attachment on or it was plugged it to the jet wash.Called a Hozelock WaterStop. Very handy except the valve inside pushed slightly on the inlet for the jet washer so didn't get 100% flow of water. Replaced with a straight through hose end and worked fine after that. Jordan

I'm on my first Karcher which I bought 23 years ago. Never been the slightest problem.

Forget Kärcher and go for Kränzle. Hot water, foam spray, high/low pressure everything you want and they last for (almost) for ever. 2017 Range Rover Vogue TDV8 silicon silver

I have a nilfisk, which is ok, but yearn for a kränzle.

Kärcher are krap. Had one once - didn't last anytime. Friend of mine is on his second - bought against my advice.

Gerni used to be the go to brand. In fact, we use "Gerni" to denote pressure washers much like the British use "hoover"
for a vacuum cleaner. I bought a Karcher after my Gerni died. I've had it for some years.

The pulsating mentioned earlier I only get when the washer is connected to my rain water tank, not the mains water. The low head of water in the tank means low pressure to the pump.

Does that mean good or bad? In Oz, "the ant's pants" means very good - much like this
