3-Stage Cleaning with AeroVac – Roomba 650 uses a powerful 3-stage cleaning system to pick up an amazing amount of dirt, pet hair, and other debris. A spinning side brush cleans along wall edges to loosen dirt and dust. Then, Roomba’s counter-rotating brushes act like a broom and dustpan to pull debris from the floor. Finally, the powerful AeroVac vacuum sucks the dirt, hair, and debris from the brushes into the back of the large-chamber bin.
Dirt Detect – Roomba uses acoustic sensors to locate dirt so Roomba can perform a concentrated cleaning on the areas of your home that need it most.
iAdapt Responsive Cleaning Technology – iAdapt is iRobot’s advanced system of software and sensors that allows Roomba to clean more of your room, more thoroughly. Roomba covers every section of your floor multiple times, cleaning areas you can’t easily reach including under furniture, around everyday obstacles, along walls and under cabinets. It automatically adjusts to different floor types and avoids stairs, drop-offs, and tangles from loose cords.
