When our last vacuum bite the dust we ended up getting a Sebo X4 Extra. Looked into the Dysons and it seemed like they work good at first but fade away after a while.
Found a local Sebo dealer, but they did not carry it in stock because of the price and that it is a little know brand here in the US. Because of this he just charged us $100 over his cost. So it actually turned out to be a good and so far we (by we I mean my wife) have been very happy with it.
