Ah, that would be lovely, if all the rubbish was eradicated, and vacuum cleaners became unnecessary. Assuming that doesn't occur, I fear you really couldn't run your cleaner for years. There's an irritating phenomenon: new breeds of allergens appear with alarming regularity, and the old vacuum cleaners simply aren't equipped to handle them. New models are required.
