This is a Light duty carpet brush and is best used for sensitive carpets, upholstery & seats. This brush is designed for gentle scrubbing of sensitive carpet and fabrics like vintage mohair, wool, and cotton. The bristles are stiff enough to scrub away stains and dirt, but gentle enough to not harm delicate fabrics. The high speed rotation of the drill combined with premium soft bristles lifts and easily extracts spots from fabric, upholstery, and carpet. You can also use this brush on leather seats to quickly deep clean leather with a suitable leather cleaner.
