Absolutely null and useless

If you feel like something is useless, I highly recommend. I am a regular customer of Amazon and this was my worst purchase. I wish the other reviews make me more alert. A single crumb of bread weighs too heavy for the suction capacity of the so-called vacuum. But the number one issue, and if your room is but an empty space without furniture, the race changes vacuum whenever it encounters an obstacle. In the end, after a few hours you will have a corner of the room with a little less dust, and that's all.
