This vacuum sucks up EVERYTHING. Before you vacuum you should get all cords and anything you don't want sucked up out of the way(I've learned from experience). Because it does have A LOT of sucking power. Maneuverability I will admit it is hard to get under some pieces of furniture and will go under a bed so far. in all it is a very good vacymn. Ease of Maintenance I usually empty my bag less container at least twice a week plus wash it out about the same amount of time. I just clean my filter once a week by running it under very warm water and using my hands to separate the the threads. They sell refills at WalMart,for not too much money. Suction Performance Excellent. Like I said earlier move cords,etc, that you don't want sucked up cause this vacuum will suck it up. Design The only complaint I have is they could have designed the container of dust you have to empty. Durability I don't know how many times I have banged this or accidentally dropped it and it still worked. And no dents or marks on it.
