I recently purchased a Shark Roadster bagless canister vacuum on ebay for my mother intending for it to be an "everyday" house vac, the only vac she would need for all her carpet and floor cleaning. IT IS NOT INTENDED FOR THIS PURPOSE.

It is kind of like a canister equivalent of the old dustbuster hand vacs that are intended for touch up spot vacuuming, or for use in cars or campers. This is obvious by the size of the dust cup/dirt chamber. It's so small that I had to empty it three times just to vacuum out my car. It has many attachment heads for carpet, drapes, barefloors, etc., which is deceiving and leads one to believe that the Roadster can be used as an everyday vacuum. I didn't put two-and-two together until after the fact but I guess this is why they call it the "Roadster." It's  a car or portable vacuum.

I will say that the suction on this vac is great, and it is very handy for cleaning out your car. The furniture attachment is great on couches because it has a felt-type edge to grab pet hair, but once again, you'll be emptying the dirt chamber more than once to clean your couch. Besides, it's really nothing the attachments on your upright vac can't do. It's just easier to carry outside for use in autos.

Bottom line: DO NOT BUY THIS AS YOUR MAIN VACUUM unless you want to stop and empty the dirt chamber every two seconds. You will be disappointed.
