For those of you that are no-so-skint, next Thursday the 22nd Aldi are selling Petrol powered jet washers for £199.
Not cheap, but its cheaper than most and you get the back up of Aldi too.
They're even doing a suction pipe that can be used to draw water from water butts for £12.99
Very handy for the sailor that is hauling out and needs to jetwash the summer crud off the bottom of their boat.
Just right for the haul-out season.
