WiFi operation. Long battery life. Simplified collection bin. Dirt Detect sensors alert the Roomba robot vacuum to clean more thoroughly on concentrated areas of dirt. The Auto-Adjust cleaning head automatically adapts its height to keep effectively cleaning carpets and hard floors.
No improvement in efficiency & space recognition.
3-step cleaning system with a strong suction provides thorough and concentrated cleaning. Automatically starts on its scheduling program and returns to docking station to recharge when battery runs low. Multiple smart sensors avoid bumping around or falling off stairs.
The robot can't work properly on the black carpet due to the low reflectance of black color will interfere the Cliff Sensor.
A combination of counter-rotating side brushes, a redesigned rolling brush – engineered to reduce trapping – paired with powerful suction cleans wherever RoboVac passes. When greater vacuuming strength is needed to get the best clean, BoostIQ technology automatically increases suction strength to 1000Pa.
It's best on bare floors.
