I received this Shark Clean & Empty Cordless Stick Vacuum & Auto-Empty System as a compliment from Influenster for testing purposes.  This Shark is lighter with hyper velocity accelerated suction power and its performance like a full-size cordless. It includes duster crevice tool and pet multi tool. It charges and empty after every clean. The auto-empty system is a plus for this vacuum however I gave it a 4 stars due to not practical and the power button location is not convenient to turn on. Otherwise it is a very good vacuum.
