Don't vacuum the same spot twice. See your coverage in augmented reality. **THE PROBLEM** You vacuum a room and lose track of where you've been. Some spots get cleaned twice. Others get missed. **WHY YOUR MEMORY ISN'T ENOUGH** Trying to remember every spot wastes mental energy you could spend on things that matter. **THE SOLUTION** VacuumAR shows blue dust patches on your floor in augmented reality. Hold your phone in one hand, vacuum with the other. Aim at a patch and it disappears. A minimap shows your coverage at a glance. Simple. Visual. Free your mind for what matters.
