I've had my shark rocket for around 15 months now. I was suckered into buying a heavy and huge rainbow vacuum years ago and it was a real pain getting up and down the stairs. But we believed it was cleaning well because the water was always dirty. One day after using it, my shark was delivered so I tested it out. There was still a ton of dirt stuck in my carpets and I filled the canister 3 times! We have since moved and live in a house with 90% hard wood floors and it works perfectly. I love the smaller attachments included too, though I only used those once. It will be great for the car. I love the rocket! Wish I went with one sooner!
