True. Every body part is beaten up on it so realistically I'll dismantle it and keep:
Wand
Hose
Motor
brushroll motor
brushroll pcb
cord
possibly the brushroll baseplate
cyclone
ball
other little twiddly bits
It shows how finicky these can be though, I've seen them blow the PCB/motor with a perfectly fine brushroll and nothing else wrong. This vibrates and flails about all over the place, probably has done for years and yet still works fine!
