A turbine that "prevents hair, fluff and dust from winding up on the filter while maintaining suction power 2x longer" . In reality, everything is exactly the opposite. If someone with long hair is found in the house, if there are carpets in the house, then the use of this vacuum cleaner is contraindicated! Hair, combined with dust, and especially fluff from carpets, immediately winds up on the turbine, and the suction power drops sharply. And since there is no indicator of power or overload, and the noise of the vacuum cleaner is not particularly noticeable whether it or not, then another problem appears: the engine starts to overheat. And you begin to understand this only when it starts to smell like burnt. This is the first negative point. And the second, falling out the back cover. This cover, under which the filter is located, starts to fall out very quickly, first after 5 minutes, and then a minute after switching on. A clear design flaw, judging by the reviews, manifested on all similar models. Vacuuming is impossible, must be returned.
