Everyone's vacuum cleaner gets hair tangled around it. The RollaReleasa removes hair from your vacuum brush roller in seconds. It completely removes pet hair, synthetic hair, human hair, carpet fibers, cotton, dust, string and just about anything else that can get wrapped around your brush roller. It features a sharp point which is ideal picking at the hair to lift it and has strong but safe serrated teeth, designed to make it easy to tear hair and fibers and pull them out. Every RollaReleasa is 3D printed in a process called Laser Sintering - a technology normally used to make parts for Formula 1 cars and airplanes. We chose this technology to make RollaReleasa strong but not brittle, lightweight and designed for use over and over again. Vacuums performed up to 80% better at collecting dirt and debris after being 'untangled'
