Not recommended for purchase. Divide the battery or suction power by 2, since at maximum power it sits down in 4 minutes. And at low power it does not capture anything. Not recommended for purchase. I don't know of a good vacuum cleaner. It's better to take a wired one, I guess Some pros: The idea is good, the execution is so-so. 4 minutes working, 3 hours charging. Enough to vacuum 4 rugs in the car in fast mode. Cons below: Exaggerated specifications in the description. Discharges quickly. Does not capture all debris.
