Rated 5 out of 5 by from WHAT would i have spent elsware , who knows I Bought this machine on Sunday 24th at Wicks store Hove, as it had already been recommended to me by my Brother, so i was not spending time looking for any other make and i believe for the price it is a great buy to enable me to get done quickly what would normally have taken me hours to do , so i am a happy Guy.

Rated 4 out of 5 by from Good all round pressure washer I am very pleased with the K4 and especially the rotary washer for cleaning patio and slabs. Very impressive result. I have purchased and extended lance to reach some places that the standard couldn't. Worth purchasing as is the pressure brush which I have used on my wood decking. The plug in cleaning solutions are good but quite pricey. My RR Sport used up nearly the whole bottle.

Rated 5 out of 5 by from Powerful, Portable, Professional Have used this on several different surfaces (block paving, pebbles in concrete, slate patio slabs, patio, drain pipes and on cars) and have been pleased with the results. Changing the accessories is straightforward and quick. On the patio and paving I mostly used the High Pressure gun, the T350 Patio cleaner wasn't as effective.

Rated 5 out of 5 by from Great for cleaning paving slabs, not so for cars. I bought this k4 3 weeks ago and would comment as follows: Assembly: no problem simple instructions. Plug and clean liquid bottles: watched many You Tube videos still haven't used them as the plastic pin on the body of the k4 looks to fragile to force the bottle down on to it. Concrete cleaning fluid: waste of time just use water and the T350 head provided. Car shampoo and nozzle: very poor result reverted to washing my car by my old method of shampoo and brush. Also consumption of shampoo with nozzle excessive and uncontroable. Variable lance great for alloy wheels, plus I bought the wheel brush as an accessory which was really good. T350 head: brilliant paving slabs look like new after 40 years without cleaning. Variable Lance: good but pressure settings difficult to set due to small changes in rotation leading sudden changes in the pressure. Needs a better control of the head adjustment. Dirt Blaster Lance: Brilliant On board pocket for the 2 Lances: too small lances get stuck in the pocket a bit of a nusence. Overall :- I still give this k4 unit a 5 star rating as the results of the paving cleaning warrant it. Perhaps I can get a lesson on how to clean my car properly from my next door neighbour who uses a Karcher machine albeit an industrial type unit.

Rated 5 out of 5 by from Fantastic I selected this model because of reputation and of course the reviews. I think the K4 full control car & home model is a fantastic power washer, does everything you want a power washer to do with ease. My only gripe is the length of hose to gun is too short so you have to physically lift & move the washer to get nearer or around the thing you are washing, but an extension of an extra 6 metres is available for an extra few quid which is worth purchasing.A quite expensive power washer but it is still an excellent, enjoyable and easy to use to use washer.

Rated 5 out of 5 by from Amazing Just moved home and have a patio in the back garden which was a mess. Not anymore thanks to the karcher car and home cleaner. Cant believe how clean it brought it up, looks totally amazing. Hardly any effort required either. Have used it to clean my car too, again simple and easy to use and my car has never been cleaner. Would 100% recommend this cleaner, no hesitation at all

Rated 5 out of 5 by from Making light work of tough jobs Great product, especially if you have different surfaces to clean. We have paving, brick, concrete and a large decked area. Being able to control the force of the water (and be able to see the setting from the handle) is perfect for the deck where a power washer can sometimes be a little strong and damage the wood. The patio cleaner makes cleaning the paved patio and concrete steps so much quicker, I couldn't believe how much quicker it was compared to just using the spray lance as we've done previously. The kit takes a few minutes to put together and a screwdriver is required to put the handle and trigger gun holder in place but within a few minutes you are ready to go. I did need to give the instructions a quick read through as it was a bit different to my older, more basic model. I think this is a bit quieter than my old power washer and I don't think the trigger gun vibrates as much as I didn't get the tingling in my hand as I have done previously, but this could also be down to spending less time using it! The time it took for me to do two sets of steps, a block paved patio and a large deck was probably halved. I used for the first time on the car this morning and the plug and clean detergent is great, it clicks in to place incredibly easily and provides a great lather. It removed a lot of effort in cleaning the car, rinsing and soaping takes minutes, a little rub over with a sponge, another rinse and your done! The only trouble is I don't think the car shampoo will go very far. We watched two cars this morning, a large and a medium car and nearly used all of it. We may have gone overboard being the first time used so will have to see next time. There are only two downsides I have found to this power washer. The hose is wound around a reel for storage which means when unravelled for use, it tends to curl and wind itself in places, so every so often you need to stop and unravel the hose. That may just be because its still new and needs a bit more use. The only other downside is that you can easily get carried away using it, anything around me when I have it out gets power washed! I only got it out this morning to clean the cars and ended up cleaning the rattan furniture and all the plant pots! Once you start, you really can't stop! Great product as it makes those tough outdoor cleaning jobs quicker and easier.
