1. Using this product for several days (not even a week). Bought for the purpose of cleaning cat hair in hard-to-reach places for a robot vacuum cleaner and for a carpet in the hallway. He coped with all the tasks quite well. 2. Average speed is the golden mean. I assume that most buyers will use this mode. I like it. 3. The smallest nozzle (from bedbugs or whatever was in my mattress) cleaned the sofa well (not visually). The vacuum cleaner removed the dust, which we did not see inside the textile material of the furniture.
