I recently purchased this vacuum as an update to my older Shark model, and I am very pleased with it! The larger dust cup is a plus, and I like that the vacuum is lighter. The Zero-M ACTUALLY MAKES A DIFFERENCE. There is virtually no hair on my brushroll after a week of almost daily vacuuming (my wife and daughter have hair for days).
I love the Shark brand, and I would highly recommend it for any family.
