How long are these supposed to last? I use one for about 4 or 5 days every spring cleaning my garden decking, my sister's garden and my neighbour's garden. On the third year, so after about 50 - 60 hours total use, my last 3 have stopped working. Out of warranty, cost about £80 quid so not worth trying to get repaired. Sitting in coffee shop next to B&Q in Charlton contemplating a Macallaster (spelling?) pressure washer for £120. Anyone with experience of these?
