I wish I would’ve had one of these babies sooner! I vacuumed the whole house in 20 mins! The connivence of not having to sweep and I can just run this over the floors once every couple days is life changing. The suction is very powerful and I LOVE the auto feature. I can easily go over a rug and not have to worry about it messing up. I did just a small little area and it picked up SO MUCH. Shark, you now have a lifelong customer. I receive the one without the auto emptying system and honestly, it’s not hard to manually empty the dust basket. I’m sure the convenience of the auto emptying thingie is wonderful, especially with dog hair, but it’s not a deciding factor if I were to purchase this. I will be repurchasing if this one ever dies. God bless me and my new Shark!
