Its amazing how different people get different results with the same hoover. We've had Dysons since the DC01, then theDC04 and now the DC07 I think.., the wife woukdnt have anything else. In 20 years ish we've had to replace a hose once, switch maybe twice and wheels once, motors and everything else have never failed.
Being in maintenance we get to repair the works hoovers, either Sebos or Henrys. Sebo, only ever touched one once, but Henrys..ive done at least 2 motors, innumerable cord rewind mechanisms (the contacts break in them) and switches.
We aquired a small Vax which we keep upstairs...,continually blocks and the hoses are too soft, plus we had a Vax shampooer, it lost suction becaise a gasket perished...can you buy one, a £1 gasket...no. Entire things useless because of a little piece of rubber.
