Cleaning the carpet with a pressure washer

The range of carpet is wide. It ranges from insensitive carpeting with a short pile to high-quality and sensitive woven fabric. Some types of carpet should not come into contact with a pressure washer. In some cases, with a measured approach and possible steam function, cleaning can be done without damage.

Dosed pressure and consideration for materials

Carpet can generally be cleaned with a pressure washer in the low pressure range. As an upper limit, the working pressure of eighty bar should not be exceeded for any carpet, be it carpeting or loose carpeting. Sensitive fibres such as high pile and materials such as silk and wool should not be treated with a pressure washer.

Quality of knotted and looped carpet

Whether and at what pressure a carpet can withstand the jet of a pressure washer depends decisively on the quality. The knotting density of a woven carpet ranges from 15,000 to over 200,000 knots per square metre. Fine silk carpets reach over one million knots. Mechanically, the resistance increases with the knot density. However, sensitive yarns can be damaged by too much water pressure.

In the case of carpeting, the embedding of the pile in the backing determines the stability. The fibres can be attached as a looped fabric by so-called tufting, also with cut loops, or simply “tucked in”. A needlefelt is made by piercing several times in different directions. It can withstand strong water pressure, while tufted carpeting can withstand different loads individually.

Drying of central importance

Carpeting brings with it the characteristic of not being able to be moved from its place. The carpet substance is deeply soaked with a high-pressure cleaner. After cleaning, extensive and thorough ventilation must be ensured.

Alternatives to the pressure washer

Wet/wash vacuum cleaner

The device creates suction and vacuum. In this way it pulls the dirt out of the gaps and the pile. However, suction is also exerted on the fabric of a knotted carpet or, in the case of carpeting, on the backing.

Steam cleaner

Similar to the function of a pressure washer, a steam cleaner applies pressure to the carpet. In addition to heat resistance, mechanical stability must also be assessed here.

If you can hang a loose carpet on a carpet pole, working with high pressure is easier. Carpet beaters in earlier times exert a similarly strong load.
