The K4 Silent Home is the quietest power cleaner we make. The innovative silent function reduces noise level by 50%. This makes this power cleaner much more pleasant to use. This model also comes with an anti-twist high-pressure hose, making using your high-powered cleaner even easier. Twists in the high-pressure hose simply un-twist themselves. This means when working you have the full use of your high-pressure hose. The elastic strap at the front of the machine makes storage of your high-pressure hose and electric cable. This pressure power cleaner is perfect for cleaning any surface around your home, from fencing to garden furniture, to your patios and decking. The additional home kit makes cleaning your smooth surfaces even easier. The T350 patio cleaner can help you clean up to five times faster, with the handy pressure dial on the top, means it is suitable for use on both soft and hard surfaces. The additional handles mean you can also use it on vertical surfaces, for example your stone walls. The 1L bottle of stone detergent not only helps to clean your stone surfaces, but also to care and protect them. The long-life water-cooled motor gives you a three year warranty.

K4 Silent Home is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from Fantastic!! I purchased this pressure washer 3 weeks ago and can't rate it enough. When I switched it on I didn’t realise it was on as it was so quiet. I love how compact it is so it doesn’t take too much room in the shed. I have 3 cars to clean and this washer takes it in its stride as it’s more than powerful enough and very well made and so are all the accessories that came with it. The best feature of all is the Premium Anti Twist hose, now all the kinks just drop out on their own.

Rated 5 out of 5 by from Great all-round washer. I purchased a K4 Home Silent washer about three months ago and I have to say it is so quiet. I already own a K2 and have had it some years now and is still going strong, the reason I purchased another, was for washing my static holiday caravan down so I bought the silent one so as not to annoy nearby caravanners, it's brilliant and I can recommend this particular model.

Rated 5 out of 5 by from Quiet and small yet powerful The title says it all really, started using my k4 silent today and I just had to saw how awesome it is. I kept blowing up k2s so I invested a little more this time and you can really tell. Everything, down to the hose and trigger are better quality and you can barely hear the pump, it's drowned out by the sound of the water! Brilliant!
