We had a dyson when they first come out , I was dissapointed with it , yes amazed at how much dirt it sucked up but dissapointed at its tacky build quality , We got a bagless panasonic for down stairs and a vax cyclone for up stairs, both have been brill and really beat the carpet , but I have got to agree, the filters are messy when they need cleaning out ....... it still mazes me how much molecular dirt there is to be sucked up ....kids eh!!! who'd have them ...... give me the dog anyday .....woof !!
