I've just used my vax platinum power max for the first time. I did one pass on quick clean setting and the carpet felt quite dry(but no water in the dirty tank). So I did the rest of the carpet on deep clean mode and the carpet remained soaked -poor pickup rate. On finishing I noticed the perspex brush bar housing was clogged so I followed the brush bar removal. What a performance! I had to undo 10 screws and then could not see how to free the drive belt. As you know there are a limited number of times a screw can be removed and replaced in perspex before the screws won't hold, then we'd have to buy a new housing. The pick up rate of this model was not as good as my old vax machine, which I threw away after six uses because it was nothing but trouble. The drive belt rusted after one use and the belt broke. I suggest a redesign of the perspex brush bar housing with a hinged flap so it can be more easily cleaned without the need to dismantle the whole machine. Perhaps clearer instructions how to free the drive belt from the spindle NOT IMPRESSED!
