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 Detergent Settinh Does Not Work I purchased this unit from B&Q approximately 2 years ago. The pressure washer works very well, but unfortunately the detergent setting worked once and then gave up and has not worked since. I believe this is a common fault with the machine, so am very disappointed.

Rated 5 out of 5 by from Top quality,well made. This is my second pressure washer. I still have the first one and it still works well. I've upgraded because i wanted a bit more power. Lovely piece of kit.

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 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

Rated 5 out of 5 by from very effective cleaning I've only used my pressure a couple of times, but I'm really pleased with the results. Initially I found it took me a while to get used to how best to hold the lance to get good cleaning results without soaking myself with the back-spray. Once I got the hang of it, though, I found it does a really good job.

Rated 4 out of 5 by from Excellent This is an excellent machine, the only problem is that one of the lugs on one wheel broke off as it was being put together. The problem now is that the wheel keeps falling off. If put in the other slot they don't turn so it has to be dragged rather than wheeled. Needs a new wheel
