I have just had to replace yet another hoover because the suction has dwindled to the point I’d be better off sucking the dirt off the floor myself. I’ve tried Shark, Seba, Miele, Dyson but nothing ever lasts more than two years either because it falls apart or the suction goes. Is this just normal? I have always had at least one dog, currently two. Not huge shedders but produce a lot of dirt/grass seeds etc all year round. Wooden floors downstairs, carpets upstairs. I’d love any tips for keeping a hoover in good condition!
