I have had an expensive Kirby for 4 years. It was bulky, heavy and a pain to vacuum the rugs, the carpet then put on the attachment for the laminate and tile. I was excited to get this vacuum because I can switch from laminate to carpet with a switch of a button. When I got it I tried it out right away. I had just vacuumed the day before with the Kirby but you couldn’t tell. The canister on my new Shark got full quickly and had to be emptied before I even finished one room. I can’t believe how much my Kirby DIDN’T get. This vacuum is lightweight, quieter than the Kirby and so much easier to use. I have to say that I’m pretty impressed with it so far. I purchased this because my daughter has one. She has had hers for a year (different model but similar) and loves it.
