Vacuum Cleaners 2 Go

me,myself, and I asked: Help! I have a Dirt Devil Swivil Upright vacuum cleaner, only had it for six mos. now and bought it brand new. I noticed yesterday that it wasn’t picking up at all. I pulled the hand held hose out to check and sure enough there is no suction what so ever! [...]

asked: I am planning to buy a vacuum cleaner for home. I came across some models. The one which are cheaper are CANISTER type and the others models which are BLOWER type are little expensive. What is the difference ? What are most important specs/feature to be observed while buying them.
Thanks in [...]
