I really love Shark Matrix Robot Vacuum with Matrix clean.  The vacuum picks up every little speck of dirt and crumbs.  I was amazed with the amount of dog hair.  I have three dogs and they shed like crazy, but the Shark has no trouble picking up the fur.  The suction is amazing and the vacuum maneuvers around the house with no trouble.  The Shark is quiet considering the amount of suction the vacuum has.  The Shark really allows me to keep my floors clean.  I would definitely recommend Shark Matrix vacuum to everyone wanting a really great robot vacuum.  I really would miss this vacuum if I did not have it to help me keep my house clean.  I love SHARK!
