We have been using the hoover for some time in a household with a dog and cat and so far there have been very few moments when we have really had to clean this brush additionally. It may happen that a thread or something gets caught in it, everything else is "self-cleaned"
This hoover has a suction power of 150 Air Watts (AW). The electrical power consumption is 525 W. This maximum suction power of 150 AW guarantees high efficiency on different types of surface.
