The vacuum cleaner has a small dust collector, which, moreover, does not fit objects larger than a g, but this is a price for compactness, so I will not call it a disadvantage. As for suction power, the main problem is that there is no single metric for it, indicated by all manufacturers. Some manufacturers sculpt the electric power of the motor as an argument, others invent marketing "aerowatts", others, like Karcher, are generally silent and do not report anything. There are no unbiased tests either, and far from all showrooms will react to the client’s wish to turn on a dozen vacuum cleaners and evaluate the suction power, at least subjectively, with the palm of your hand. In fact, this vacuum cleaner more powerfully than the old Electrolux Cyclone Power and more powerfully than a couple of "penny-ing" cheap ones from Samsung and Midea, but noticeably weaker than the Karcher WD2, which does not have a HEPA filter. I would have preferred more suction, even at the cost of more volume, size, or price, but I couldn't find something that harder, has a HEPA filter, and costs a reasonable amount of money, rather than like a laptop.
