Rated 5 out of 5 by from K4 Silent Bought this amazing new K4 Karcher Compact Silent power washer for one reason and one reason only. Yes, you have guessed it, it is silent. I can clean my car for hours now knowing that the neighbors are not going to complain about any noise. Brilliant bit of kit, more powerful than my old K2. Every family member now wants to have ago on it. Have used it for the car, conservatory and all the house windows and guttering too. Best £199 I ever spent

Rated 5 out of 5 by from Many years ago I had one of the first 100 bar Karchers , when the lance needed replacing for a second time I thought I would replace it and get a new model bought a 160bar from another pressure washer supplier, that was cheaper but only lasted 16 months then went in a puff of smoke, the pressure never seemed and different to my old model, So I replaced it with this model and what a fantastic machine my paths patio and decking have never looked so good, thanks for a great bit of kit Regards Geoff

Rated 5 out of 5 by from I actually have the K4 Silent which is not shown I bought the Karcher K4 Silent washer although I have a Karcher which I have had for some years and is still going strong. I decided to buy a silent washer as I spend a lot of time at my static caravan and wanted something a little more quiet so as not to annoy other caravanners whilst washing down my caravan and it is just the job. It is so quiet, the water coming out of the hose is noisier! It's brilliant - well done Karcher.

Rated 4 out of 5 by from Very good Power washer pity about the Turbo Lance! The K4 is great but the Turbo Lance tends to seize up. A liberal squirt of WD-40 down the tube gets it going for a while. It has only been used three times over the last 18 months to clean my concrete yard and this is what happened the last time. The Bosch one I had before the Karcher lasted about 8 years before it seized up. Other than the Turbo Lance, every thing is great

Rated 4 out of 5 by from Wet and moderatly angry I have had this product about six months now, it works well, it has some great features, I purchased the patio cleaning head it works really well and does clean off dirt and stains, and is easy to use. The Lance's supplied both are very good, and the soap dispenser works well, and makes washing the car a breeze.

Rated 3 out of 5 by from I can't get excited by this. Like most "premium" products there seems to be a whiff of hysteria as customers get caught up in self-rationalisation of the purchase. The Washer is what it is; it washes. It will get used once a year on stonework. I refuse to get caught up in a system of high-prices accessories and even higher-priced chemicals. Washing the car is a complete faff and can be done in half the time with a bucket, sponge, chamois and old electric toothbrush for the intricate bits (eg, wire wheels). Underwhelmed sums it up.

Rated 4 out of 5 by from K4 water leek I bought this on 06/2013 but did not use it for about a year. We have been using it for about 15 months when it developed a water leek from somewhere in the inners. repairs under warranty were swift but I worry about the future reliability
