Well curiosity got the better of me & I went out and picked one up from the local M/C dealer. Verdict ...well its certainly not a replacement for a mains pressure & a 130psi equates to around 9 bar & my mains pressure washer is 100 bar so thats around 10% of the power. It has it use's though & I found it handy for cleaning around the inside of the door seals on the 4x4 as the low volume of water means you can get into those tricky spots without dreanching the inside of the vehicle. I think it will be useful on a camping trip for cleaning the dust off the back of a vehicle etc, also good for engine bays & motorcycles where a higher pressure washer can push dirt behind oil seals.
Says in the manual that you should only put cold water in but the blokes at the M/C shop reckon they put warm water in & use them as shower after a day of dirt bike riding, could be handy on Stockton beach for a quick rinse at the end of the day & same goes for the surf rods & reels. Well I'm sounding like a salesman, simple setup though with a marine type pump & pressure switch, wish i'd of though of it though as the bike shop said they are selling quite a few, story of my life.......

I bought a normal pressure washer for $79 and connected it to tank water - if I want to run it off 12 volt I'll use my Inverter.
