K4 Premium Ecologic Home is rated 4.5745 out of 5 by 47.
Rated 4 out of 5 by from Very good and very solid I bought this mainly for cleaning patio areas. It is excellent for this and the work is completed in a fraction of the time it used to take. I'm not convinced that the soap dispenser is doing everything it should; it's hard to tell. Overall, it is an excellent washer. However, as with just about all products today, the assembly instructions and operating instructions are not very impressive. In this day and age, why is there not a video on a DVD or on the company website for both assembly and operation of every single product in the range? Still, it's a very good washer.

Rated 4 out of 5 by from Powerful This is a good piece of kit. For areas that are very flat the patio cleaner is excellent, not if you have any gravel around the edges though. For very dirty areas the high pressure hose is superb but it may have to be used very close to the surface. Not impressed with the detergent dispenser, low power use only so its a bit of a waste of time. On a couple of occasions the washer unit itself has almost fallen over so be careful on areas that are not flat

Rated 5 out of 5 by from So glad I bought this! Always fancied one & but the bullet about a month ago. Have used it on our cars, driveway & neighbours path & the results have been fantastic! Our drive looks brand new & our neighbour couldn't believe the difference it made to her path!

Rated 5 out of 5 by from Worth every penny I bought this a few months ago I didn't think it would work as well as it does but when I tested it I was really amazed at my dirty looking slabs they now look like new ones I also have the window vac which is truly amazing.

Rated 5 out of 5 by from Easy to use, brilliant results Took a while to assemble all the parts. Used the washer to clean my drive and patio. Could not believe how dirty my patio was, the dirt blaster just blew the dirt away. Nine years dirt, one wash, now looks like new.

Rated 4 out of 5 by from Not a bad machine BUT Bought this earlier in the year detergent dispnser was damaged and had missing component, very quickly replaced by Karcher BUT have yet to get the detergent dispenser to work at all. In terms of cleaning off decking, driveway and pathways its very good and works well. Excellent on the car removong brake dust round wheels etc cant fault it.Very poor design regarding the power cable stowage..it doesnt have any and the detergent diepnser is useless aaside from that it does what ot meant to do.

Rated 4 out of 5 by from Purchased in 2014 Really pleased with the performance in the first year. This year when I used it the motor was pulsating which I understand now was possibly an air lock/ blockage. Tried to clear it as per instructions from Help line but it didn't work. Customer services arranged for the washer to be collected by courier and the washer as returned in one week operational again. Excellent after sales service. With a 5 yr warranty I have peace of mind.

Rated 3 out of 5 by from For the Money its ok the atachments let it down The unit is Good but the vari lance is a joke on min to get the soap out its a joke were on all there videos it shows a fine mist i have had the lance changed a engineer out who confirmed its the bad design of the vari lance, so i bought a K2 Vari lance and bingo as this changes the jet at the end as well as reducing the power. the vario lance on max tho is fine and the eco idea is cool as i have now used this to wash my canal boat using canal water
