Boost mode is as good or strong as a corded floor vacuum and the charge only lasts 9 minutes. Mostly in medium mode, I used the Dyson and was able to clean dirt and long hair with no problem. I was also able to quickly gather gravel from the floor of the vehicle.
Dyson didn't shine. But when we were offered it I was grateful for the idea. Hopefully, soon enough, when this one no longer works, I'm going to go back to the bagged type of Hoover. Cheerful Vacuuming.
