I have purchased many vacuums that say they are good for hardwood floors and dog hair, but this little wonder is the first that actually works!!!  It is light - I can carry it around.  The wand is long enough that I don't have to bend over to vacuum the floors.  The bag is large and lasts 5-6 cleanings.  It does not push the hair around, but actually inhales it!!!  The price is wonderfully low.  Anytime I would even look at a vacuum cleaner I would perspire, but this little gem gets the job done before I even know it.
