When my husband first bought this (wife writing review) I thought why do I need this....I have a vacuum.  After using it once, I was hooked.  For such a little thing it really does the job.  So many times when I need to just spot vacuum, this is so handy to use instead of pulling out the big vacuum and unwinding the cord.  Works great on our hardwood floors, easily goes way under dressers and shelves.  Like that it has the extra battery.  The battery life is only 15 mins or less so it is helpful to have your other battery charged and ready to use.  We bought several for our church to vacuum the pews.  I would repurchase this product again.
