I used this as soon as I received it. Having 3 kids in the home with their same-age cousins that frequently visit, let's just say stuff says on the floor. Our lower level is hardwood and our top level is carpet with stairs. I LOVE that I can detach this to use on the stairs. Although it is already lightweight. It has 3 power levels which is perfect. Shockingly, we never had to use the highest suction level, despite our carpet upstairs being plush and thick. With our old vacuum we had to use a higher suction level. It is SO easy to empty the canister. It charges quickly. It says a 40 minute run time and my husband was concerned about that, but we could vacuum the entire home (4 bedrooms and kitchen and dining room) before the battery ran out. It was easy to clean the filter in the sink. I love that I do not have to replace the filter frequently. The brush isn't a true "tangle free" but it is removable to wash, and that is AMAZING!
