while charging is enough for 2 times to vacuum an apartment of 80 square meters (this is about 20 minutes) with an interval of a couple of days can stand on a brush without support, but I don't use it Pros below: The first vacuum cleaner I have is Polaris PVCS 0822HD, so in comparison with Polaris Wessgauf: - VERY powerful - picks up small Lego pieces, watermelon seeds, cat food - the pipe is shorter than that of Polaris, with my height of 156 cm this is a plus - all parts are very easy to detach - the brush is made somehow so that it is easier to clean it - Removable filter that can be pulled out and washed - due to the fact that the main pipe is shorter, it is not clogged with debris - nothing comes out of the brush when held vertically - vacuums the carpet Some cons: these are rather non-critical features: - due to the large wheels, the brush does not go into narrow spaces between cabinets - harder (a six-year-old cub vacuums only one room, with a polaris it vacuumed two) - louder
