A laser makes invisible dust visible on hard floors. A piezo sensor continuously sizes and counts dust particles – automatically increasing suction power when needed. LCD shows what’s been sucked up in real time. It has the Laser Slim Fluffy™ cleaner head. 25cm-wide cleaner head engineered with soft nylon and anti-static carbon fibre filaments to remove dust from hard floors and narrower gaps. With a low profile to reach further under furniture.
