Upgraded from a K2 which was awful and glad I did. This is so much better quality than the K2 and weirdly easier to put together. But the real test of course was using it. So much more powerful than the K2. Definitely recommend this model – worth paying more for the better quality.
Worth paying for a quality washer. it replaced a cheap halfords one i had which was cheap quality and soon broke. Lots of additional accessories available too for various cleaning needs.
Bought it for my patio which it did clean but it took a long time and used an incredible amount of water. Wasn’t as quick or effective as what the professionals use. That being said, it did do the job which is better than many power washers.
I’ve had a K2 for years but finally needed something with a higher pressure and flow rate. The k4 is excellent value – Amazon’s deal was much, much cheaper than other retailers and the ‘Home Kit’ also includes the patio/decking/wall cleaning attachment that retails separately for around 80, making this deal exceptional value. Used with a foam cannon for applying pre-wash on my car the performance was much better than the K2 due to the updated performance. Assembly instructions aren’t great, but there is minimal assembly required (wheels, handle, attachment cradle) but there are plenty of online / YouTube guides of you are unsure. Definitely recommended.
This is my second Karcher jet washer in ten years upgraded to a more power full unit and quit satisfied so far, find the jet hose a bit cumbersome each time i us it, but overall its a good produc
The best pressure washer in my option does every thing that I want it to do but I have a patio cleaner as an extra. Replaced my old K4 which was over 20 years old. Lets hope this one lasts as long a 5 year warranty helps.
The choice of models allowed me to pick out which one suited me most. Not disappointed and does everything I expected. Even the wife can operate it thanks to the extending handle etc. (joy can take a tea break)
Granted I’m in my 70’s but have always been good at self assembly! This one was a pig to put together. The pictures & the app were a bit of help but it took me about 30 minutes to realise the base had to slide down & not just fit against the thing. All the bits were there though & eventually it was ready to use. Just a dribble of water coming out! Exasperated I turned to YouTube. Oops. I didn’t realise you had to switch it on I thought it was like the lawn mower – just squeeze the handle. Got it going with the brush attachment & wow our patio never looked as good! Was it worth the angst? Eventually yes it was!!
Bought this to replace an old Karcher K2 that had finally failed. This is much more powerful and easy to use. Requires a bit of simple assembly. The variable pressure lance is very useful. It cleans very well. Only minor complaint is storage of hose is a bit of a pain as it doesn’t coil easily.
Our patio was really dirty, it was laid in 2020 and it was really mucky, we decided to get this one and it has brought the patio up like new, really pleased with the results. really happy with this item and feel that it was a really good buy
