this is a replacement for a Karcher in which the pump split, and the motor started to spark & smoke alarmingly. So far it seems a solid well-made product, all the parts fit together smoothly (better than the Karcher which was a pain) and it works well, with plenty of different nozzles. Nice design - connections are in sensible places and there is a built-in detergent tank which dispenses at low pressure only - clever. On-off switch sticks out and seems flimsy (see previous reviews) but no trouble so far.
November 2011. Still going well - just washed out the greenhouse, etc etc. I broke the brush attachment in the summer, don't lean on it - the stem is a bit thin and weak. Otherwise a good buy.
