Ordered primarily for dog hair on hardwood and porcelain tiles. And I sweep crumbs off the kitchen floor on a daily basis (I have a sweeper that I love, but it's getting harder and harder to find XL nozzles for it. Not to mention it's hard to sweep up accumulated dog hair, blow it away), and I chase them around the room) I also have some low pile floor mats that I use them on. Most of the time, the power saving mode works fine. I only switch to high power when working with carpets or in placesโฆ
