I have the really cheap two turny knob Bosch, the panel that hides the filter knob has broken off, it is a bit bashed where I threw a marrow bone through the door from the living room and hit it, and it is still going strong 8 years later.
I wash all the dog towels and vetbed from hairy fluffy Elkhounds five at one point and yet the filter hardly clogs.
Having said al that it will break down now, but at £180 that it cost I ahve had good value.
