I've repaired a few at work, you can get all the spares you need for them. although I have has to bin a couple, think vacuuming plaster/cement with no bag, all the hose was solid, filter shot, motor caked up, just not worth the time/cost compared to a new one. I do prefer the vacuums with large filter cartridges, think shopvac or equivalent, but this comes from a rubble/dust DIY perspective.
