The vacuum cleaner sucks with its 7.2 V strong enough. The filter is washable and a replacement filter is attending. He should be able to serve for all small in the kitchen, and in front of my stove, he makes clean. The battery holds its 4-7 minutes, I guess. Charging him only when unreasonable empty, ie sucks anything. Charging Duration determined 10 hours. But that will be similar for all the sucker class, especially for 30 Euro. Therefore, a recommendation.
