The Karcher K090 has been in the family for a few years now but I have never really had need to use it until this year when I decided to give the little bit of patio a clean for the summer.

The unit itself is very compact being about 9 inches high and about 18 inches long although it is deceptively weighty which thinking about it isn't surprising as it contains a compressor.

Assembling it all is a quick and simple process. First put the nozzle on the gun by pushing it against the spring in the main handle of the gun and twisting 90 degrees. The attached the gun to the pressure washer by pushing the connector on the threaded 'blot' and then tightening up the cover over the threaded bolt. Then all that remain is to attach the hose pipe (a hose with a 'hoselock' style connector is required) and plug into the mains and turn on the large switch on the main pressure washer unit - that's it process complete.

When not in use, even if turned on, the unit makes no noise. It is only when the 'trigger' on the gun is pressed does the compressor start up and it gets a little noisy. The first time the amount of pressure generated comes as a bit of a shock but you soon get used it, the jet produced is quite flat and wide in shape. To clean the patio the head needs to be held a few inches from the slabs which means the jet is only a few inches wide, thus cleaning just a small area takes several hours after which the hands and arms do ache a little especially as there is no way to lock the trigger open, so it has to held.

It is amazing how clean the patio comes but the downside is that all of the grim is thrown up over the person doing the cleaning, so old jeans or shorts are a must. The K090 has the option to use detergent, all you heed to do is pop the feeder line which is at the back of the pressure washer unit into the detergent of choice, which could be anything from the official Karcher detergent to a home brew of diluted washing up liquid.

All in all the Karcher K090 is superb, it is very reasonably priced at about £50, it cleans very well even though has 100 bar of pressure. It is also efficient to run as it requires 1400 watts and uses 330 litres per hour which is not much more than a standard hose pipe.

Using the Karcher detergent is one of the most expensive things you can do with your pressure washer - it goes through VAST quantities and it's not cheap - far better to stick with a home-brew washing-up liquid based thing. Sam.
