i have had a dyson for a about 10 years now, and this is why i think i love it....
you can book a service call, and our dyson engineer, Steve who is just lovely anyway, totally and completely rebuilds it, its like having a brand new machine.
today he replaced the clutch, the brushes, the bin, the cleaner head, the filter pad, the hoses, the cyclone and the sole plate. ta da! brand new hoover! fraction of price of a brand new hoover! and im covered for a year if anything goes boom, it cost me £6 more to cover the entire machine for a year... it should be good for at least another 5 years, but i replace hoses and bits quite often, so im covered for those and dont have to pay again for a whole year.
i love dyson. and steve.
