LEGEE-668's cleaning process is named as Fastbrush 4-stage cleaning means all-in vacuum, dry mopping, self-watering and wet mopping. The power vacuum can suck dust and hair and the reciprocating cleaning mechanism at 600 times/min imitates the human behavior to remove the stubborn dust off the floor. The smart self-watering is as the third stage to dissolve stains, which cannot be vacuumed or cleaned dryly. The rear cleaning cloth not only wipes water and clean the melted stains but also polishes the floor.

EGEE-668 uses Laser, Encoder, Gyro, E-compass and Position Estimation to detect and measure the space around it. LEGEE is an advanced navigation system that allows it to avoid furniture and other objects. It also can precisely plan the cleaning path to clean an entire level of your home.
