Washing carpets insufficient

The rotating nylon brushes are below the attachment of the vacuum cleaner, ie they do not touch while vacuuming the carpet. Thus, the carpet is cleaned only superficially, a deep cleansing impossible.

Manual height adjustment of the nylon brushes do not exist, they are firmly anchored.
For vacuuming smooth floors (tiles, laminate) this device is.

Sorry, we do (after 3 months) detected this deficiency until after the 14 day return option, since only the stair mats are provided with us with carpet flooring. Now the dealer asked in return a compensation for use, although this is prohibited by EU directives and the Federal Court. A rectification of defects is not offered.
