Well FYI the DC05 has had a hard life, and. I used it for plaster dust and never washed the filter till it couldn't suck anymore, as long as it has enough suction to pick up plaster dust, and if it overheated, I don't care. Plus I was saying that the DC41 Mk2 would be suitable for this type of carpet. I do still like Dyson, but that's not to say I am bashing them.
