The Black & Decker PSV1800, sometimes called the Black & Decker Pivot Vac, is a bagless and cordless stick vacuum that is effective on both bare floors and carpets.  It lasts a fairly long time on a single charge and comes with a 2-year warranty.  There are some consumer comments that it is awkward emptying the dirt canister however.  [REF Black & Decker Vacuum Cleaner Reviews 2009]
