Hi, my dyson dc07 won't pick up properly, it seems the air doesn't circulate in the cylinder anymore and when you take the cylinder off to empty what little it did manage to lift the bottom of the cylinder is very hot. Can anyone tell me what I need to do to fix this problem.

Go and have a look at the Dyson site (Dyson UK - Dyson homepage (http://www.dyson.co.uk/)) as they have a trouble shooting section.
