No great expectations on the performance of this 'broom', but was quite surprised at what it could do.  We bought it to do quick cleanups of our rooms that have hard wood flooring, and keep on top of the fur that our husky leaves behind.  As these areas are actually quite large (probably totaling 800 sf), wasn't sure if the battery would hold up before the job was done.  Absolutely no problem.  There's no loss of power on completion, which includes using the 'rug' setting on our low pile throw rugs.  The rug setting doesn't work on shag rugs, but that's understandable.  But it can handle low pile rugs and carpet rather well --- again, for a quick cleanup between serious vacuuming.
