I bought one of them cheap petrol power washers a few years ago only lasted about 2 years.
Absolute rubbish.

Works fine when it does but burns 5ltrs of petrol an hour and will break your heart cutting out and stalling. Cheap construction. I was working for Musgrave at the time we got about 20 in and about 15 were returned. I would have returned mine if I wasn't so lazy. We did not get them in again. A kickass electric one can be got for the same beans.
