I wanted a lightweight, cordless vac for in-between vacuumings and for stairs. After looking at the reviews, I selected this one and am glad I did. It works great on wood and lineoleum floors, is easy to empty, and gets up enough of the lint etc. from carpets that I don't have to drag out the big, heavy vacuum cleaner nearly as often. The battery stays charged long enough to do two sets of carpeted stairs, kitchen and dining room floors, a once-over on living room and two bedroom carpets, and four or five throw rugs. Then if I need more time (I -never- need more time for vacumming) I can very easily swap in the extra battery. It's easy to empty (it's essentially a Dustbuster on a stick). It won't replace a big vacuum cleaner -- doesn't deep-clean the carpets -- but if you don't like vacuuming, this little tool lets you do the big jobs less often, which to me is a godsend.
