In fact, the vacuum cleaner gives out full power for 2-3 minutes of continuous operation, then it decreases by a noticeable percentage. In principle, it is enough to collect all the garbage well, but the feeling of cleaning efficiency is not very good. It seems that you choose how fast to vacuum, but in fact he chooses it for you) It seems to have such a system of protection against engine overheating, but very strangely implemented, because the power is always reduced by the same amount and remains so the rest of the cleaning time in continuous mode. If you turn it off and turn it on after a minute, it can work for another 2 minutes at a given speed, after which the power drops. Bottom line: there is really enough power for good cleaning, but it will not be possible to fully realize its full potential of power. Also, by reducing power, autonomy increases. In turbo mode, it can work for about 10 minutes. Also, it became possible to buy additional filters, a battery, and all spare parts for repairs
