This value measures the dust absorption on the highest suction setting on a defined test carpet. It is rated in classes from A to G. A vacuum cleaner rated carpet cleaning performance class A has to be able to suck up 91% of the dust from the carpet. The dust absorption for each classification reduces by 4%, which means that a class C vacuum cleaner will only reliably absorb 83% of the dust, and a class G less than 71%.

In Germany, carpet adhesives must have EC1 approval (building approval for harmful emissions in living and other rooms; the “Blue Angel” signet, for instance, is issued with an EC1 rating). A number of adhesives with EC1+ certification are available, and their emissions are significantly lower than the legal specifications.

Vorwerk flooring does not offer a direct laying service. The specialist company where you purchase your carpet will usually also be able to lay your carpet flooring or tiles. Specialist companies include, for instance, decorating companies, interior decorators and flooring and laying companies. When purchasing a carpet through the Internet, find a suitable laying company first that will lay your carpeting for you professionally once it has arrived.

When laying woven and tufted carpets, it is important to use the correct tools and equipment. These may vary depending on the particular substrate, the type and place of use, and the purpose of the floor covering. It is also important to observe the direction when laying carpets on stairs or landings. The same applies when a number of carpet sheets are being laid in the same area. As a general rule, the appropriate tools must be used when laying carpet.
