Here is the thing I know ALL dry vacuums (bag or filtered) loose air flow and never loose suction. What I noticed with dyson is, the quot;never loose suctionis more a copy right than technology patent. Why any vacuum company cannot claim no lose off air flow? Which what does the cleaning, not suction. the little shark vacuum (shaped like a football) never looses suction too. So can you show me a vacuum that looses suction?
Yes I can! Eureka is number one, Hoover is the other. Both of mine lost both air flow and suction. Along with that they lost their light, their wheels, the brushes on the beater bar, and anything else attached to them. I would like to say they sucked, but that was the first thing they lost! Trash.
Yup it's nothing but a gimmick Dysons lose airflow much faster than some of my bagged vacuums but as for losing actual suction...i suppose an abused rainbow could in theory if it's not emptied properly you could have a build up in the fans causing a loss of suction but that's only if it's not taken care of
You're right. Vacuum cleaners don't lose suction due to general usage and failure to clean filters. The only way it could happen is if the cleaner in question has a malfunction which causes the fans to turn at a reduced velocity, if a seal has developed a leak, broken fan blades etc. So to answer your question... No I can't.
