Common problem with these-see many of them at the Vacuum Cleaner hospital in town waiting for surgery to get their wheels reattached-now its to the point the whole machine is replaced if its still under warranty.If not,the owner has to buy a new one-poor design.-flimsy plastic construction.Not your Mothers or Grandmothers Electrolux!Many times the owners buy a better machine at he Vacuum Cleaner Hospital in town-they take the broken 'Lux back to Lowes or whatever for refund to pay for the new machine.also to reattach the wheel the WHOLE rear part of the chassis has to be replaced.Its a major job.Many vac repair techs don't want to have to do the job.Thats why they try to have the machine replaced.
