This is a wonderful vacuum! It’s so lightweight and powerful at the same time! The whole concept of returning it to a base to charge and the automatic emptying feature is genius!  It’s always charged and ready to go and I don’t have to mess with emptying it since the container it empties into holds a large amount of debris! It’s so convenient. 
It does well on my regular carpet and also on the hard floor but if you are constantly changing the type of floor through out your vacuuming the auto feature struggles a bit but it still gets the job done. When I take it off the base I have to tap the bottom down with my foot everytime but that’s not a big deal. It can be a bit loud on auto mode and when it empties but had a feature to silence the empty option til you are ready to use it. 
I really am a fan of this hardworking cleaning tool and I’m happy to make it a part of my daily home cleaning routine! Well done Shark!
