We keep two of these, one upstairs and one downstairs for quick clean-up jobs. It saves us the task of using our house vacuum proper which is the size of a small car engine but barely picks up bird seed, so here's a tip, if you want a vacuum to actually suck then get rid of all the filters, including Hepa and the like.  On the Flair there are two filters, one each side of the main body, remove the plastic filter grills, unhook the foam filters, throw them away and replace the grills. Do this with all your vacuum's and they will then perform as anyone would expect. The Flair's don't last forever but for the money, ease of use and for having a power head, which is perfect for cleaning stair carpet, they are indispensable.
