Ematek Self-Cleaning Pet Hair Removal Roller Reusable roller for removing pet hair from fabrics, without the need for batteries or replacement rollers. This roller works thanks to the electrostatic charge generated when it is rolled. For quick and easy cleaning, simply roll it back and forth to collect hair stuck on sofas, beds, carpets, car seats, and all other fabrics. The hair is automatically collected in the upper compartment so the roller always remains clean, and emptying the collected hair is extremely easy. Dimensions: 19.5 × 11.5 cm
