dh dismantled our dyson one day and laid it out in pieces on the patio
it had been making an unpleasant smell for a while and we couldn't seem to find out why....
once the dyson was fully dismantled we discovered the whole of the insides were splattered with decaying flesh - I think my aged mother had hoovered up one of the cat's sacrificial offerings.
After scrubbing and blasting the whole thing with the garden hose we left it to dry and dh reassembled it.
now that's what I call fixing the hoover
