I consider the shortcomings are not critical, for a handheld vacuum cleaner, for such a price. I advise you to buy if your requirements for a vacuum cleaner match mine. I am supplementing the review after 3 months of service: The traction is still powerful. The vacuum cleaner works properly, I will draw your attention to the fact that I use it about 2 times a week. The carpet with a small pile cleans well, the dust pulls out with dignity! But, when cleaning the carpet, it heats up more. Be careful, for those who need a vacuum cleaner specifically for cleaning carpets, look for a more powerful model! This one may not be able to handle heavy loads. Happy shopping everyone!
