I bought a cheap pressure washer from Tesco (£25)
It was predicted that it would not last. That was true. The second time I used it, it started sounding like a bag of bolts and the pressure went right down. Took it back and got a refund.
So, given that I still need one (a half cleaned patio will not do), and that I've just moved house (read skint) can anyone recommend a reasonably priced washer?
