We use our "Kärcher" since longer to clean our warehouse. In terms of wet eyes, I can only say positive. Although the volume of the collecting vessel could be bigger in my opinion, but my boss says that arrived. Until about 8-10 liters it works hervoragend. (For home use, absolutely sufficient.) In dry eye the Kärcher eats just about anything. The only drawback is the dust filter. For a very fine dust you have him beat the öffteren, but he keeps even our most extreme terrain a good year. All in all a real workhorse that I bought privately for car, home and garden. For those who evaluate the volume of the Kärcher suction negative: Buy yourself a broom. The makes no noise. PS: Had previously a no-name vacuum cleaner. Absolutely no comparison.
