Query: I'm glad I kept my old windtunnel...

The HEPA filter quits cleaning itself and you have to have a second vacuum to clean it....It is really a messy proposition to empty the bagless container....This is a truly poorly designed machine that Hoover has not given me any satisfaction on. I spend more time cleaning the wintunnel 2, after I vacuum, than I do in the actual vacuuming.
