The only good thing about this product is the 12 foot hose. I purchased this product due to the name Shark, thinking I would get a better vacuum than a Hoover or Dirt Devil.  We have a commercial grade area rug in our office on top hard wood.  The rug is black and you would be amazed the amount of debris which it left behind. We even switched the setting from carpet to hard surface due to the low pile.  No change.  This is also a  top heavy vacuum and will fall over time after time while using the attachment features. Was honestly shocked by the construction of the switch to change the floor settings.  Not happy with my purchase and would return it if I could. Also, what is up with have more attachments than areas to place the attachments on  the vacuum?
