Looking for the impossible I think. Meduim size, portable. Flexible hose, hose that does not pull off vacuum if pulled on, filter that does not fall off into tank, the ability to roll and not tip over from being top heavy. Ok I can do with out wheels if needed. Some what quiet for a vacuum. My current one(Craftsman)fails at all of above. All just seem like terrible designs. General clean up use. Everything I have tried does well in one area at most. What are you using?
