Everybot Inc is based in South Korea (Republic of Korea) and lists robotic cleaning devices on Global Trade Plaza. Several models use a dual-spinning mop system with two round mop pads that drive and clean simultaneously without wheels, applying the product's full weight to the floor. Automatic water-supply mop kits keep the mops wet during operation, and anti-collision and fall-prevention sensors are included. Smart vision mapping with a vision sensor and a single wide-range, long-distance laser enables autonomous navigation, while IoT convergence links the robots with smart devices for new concept IoT services.
