Don't buy one if you want to use as in my case the power washer, it doesn't like to get wet, and the welding on the main unit is poor at best, we've had two of these on one job and both units wheels fell off, and before the job was completed they simply gave up working!

Nice bit of kit. Just bought the pressure washer attachment for now as it was half price with the engine.
Tiny bit of choke required to start even with a brief off period. Loads of welly to spin any attachment. As it puts out 6.5 hp that is more than you can ever expect from an electric jobby. (6.5hp = 4.85Kw)
And unlike an electric one the pump doesnât have a duty cycle so if like me you keep blasting for say 5 hours (totally knackered) the pressure is maintained.
Being on all the time, the engine is a little noisy for the environment but I always wear ear defenders. So as you hit the gun or put the engine under load the dBâs (noise) increase. Have run for about 10 hours so far and here are the findings.
Excellent maintained pressure from pressure washer pump (very dependent on water mains pressure as you would expect).
Depending on lance setting the water pressure WILL remove anything not fixed down but that is what you want from a jet wash although you can turn the motor down if required.
Going at full tilt it gets through 3L of gas in an hour + but you will have covered more mileage than an equivalent electric version.
On the negative side there are 2 plastic knobs with metal inserts that screw the handle to the frame. Not a good idea as they come loose with extended use and you have to tighten them hard if you donât want the handle to wobble. I fully expect these to break at some point being made of plastic. A better idea would perhaps be 2 metal pins with over centre levers or with pip pins.
As per other reviewer the plastic outer of the petrol tank cap mysteriously disappeared leaving just the inner metal bit, so worth sourcing a better cap from elsewhere. Itâs nothing elaborate so no need to worry.
The rubber compound from the wheels is coming off slowleeeeey :)
Have got through 3 electric versions from a Kew to a Karcher and what attracted me was the no nonsense design approach. What you see and get is all you need so you donât waste money on silly plastic drums that fall apart and inferior motors that die after a couple of years and if things do wear out they are replaceable and of course there are other attachments to boot with more in the pipe line. Iâll take a guess at a cement mixer drum :)
Go get one tomorrow you wonât be disappointed.

Â by Gibbon Excellent but QA poor!
I bought the engine and all the accessories in January and have tried out everything. The generator has powered a 2.2kW chainsaw without any problem at all. The power washer is worth it just by itself; I have been using it to clean off 25 years of muck off a patio and it has come up looking as if the patio has just been laid! The pump is great once you get it going: priming it can be a bit of a hit and miss affair and the amount of water it can shift is fantastic. However! The petrol cap has disintegrated and fallen off and I have found that the exhaust manifold was never screwed on properly and one of the bolts hasn't been screwed into the block fully so its being picked up by Evolution for assessment. Overall 5* as the whole package is excellent but I have marked the reliability down due to these problems and long term.....we shall see!

Rated 4 out of 5Â by OllyG Okay but flimsy
It works fine, just keep it level.
It always started almost first time and wasnt too hard to connect to the genny. Easy to move about, easy to refill.
But its really flimsy in important places. The start rope got caught on mine and sucked into the gizzards and snapped. The pull handle is flimsy plastic and disintegrated. When i took off the spring loaded cover, it was all made of really weak plastic inside. It had all come apart.
So now i have the cover off and just use a bit of para cord to start it, wrapped round the fast spinning wheel thing. Just hope my hand doesnt get caught.!
Id still get one, its cheap and good, just a pity some rubbish bits were included in an otherwise cool design.
