Some pros: The first day is very cool. There is nothing to compare with only a conventional hose vacuum cleaner. Comfortable in using. As they say, the power is on top, the wires from the laptop are sucked in and the curtains, so that cleanliness from dust is ensured. Cons below: No, except for the battery, although this is not a disadvantage of such dimensions. The whole apartment in 33kv / m2 was cleaned for 50%. this is a great indicator as for me, I don’t know about anyone .
