Before buying, I read the reviews, resigned myself to the insufficient length of the cord and the fact that it cannot be parked vertically and bought it. I've been using for about a year. As I use it, I realize that I did not make the best choice. He vacuums poorly! I read the reviews of others (for whom he vacuums like a beast) and I don’t understand, am I so unlucky with my particular vacuum cleaner? Or - as you use it - its suction abilities deteriorate so much on their own, in principle? To be honest, right after the purchase I didn’t pay attention to the dust suction power, but now it’s not enough, I always want to turn the power up a little more. But there is just nothing to twist! There is no such button! But there is a hole for adjusting the air stream - to decrease, which I constantly, in the process of cleaning, accidentally touch and thereby worsen dust collection even more. So, even with all due respect to the Karcher company, I do not recommend this vacuum cleaner.
