1、THOROUGHLY CLEAN: Double disc twisting and wiping, alternating cycles. Double wheel twisting and wiping imitates manual hand wiping, to achieve a rubbing movement of 70 revolutions per minute, achieving twice the result with half the effort when cleaning the glass. 2、14.5CM HIGH CLEANLINESS WHEEL: Circular window cleaning machine adopts a more advanced sensor built in technology, which can better fit the window corners compared to models with sensors at the corners. The iconic 14.5cm diameter disc meets the dual requirements of cleaning speed and cleaning rate, better meeting the needs of comprehensive cleaning. 3、MULTIPLE PROTECTION FUNCTIONS: Single disc suction 2800Pa force, double disc suction safer, double suction double suction, combined with multiple safety protection measures, to ensure the safety of the body. Border detection, intelligent detection system sends an alarm to change the routine when encountering frameless, identifies obstacles, and adjusts the routine in real time to prevent collisions. 4、UPS POWER OUTAGE BACKUP SYSTEM: Even if there is a power outage at home, the robot will not fall. Accidental power outage can also adsorb for 20 minutes and continuously alarm, while being equipped with a climbing level safety rope lock to provide protection for high rise window cleaning. 5、AUTONOMOUS PLANNING ROUTINE FOR ARTIFICIAL INTELLIGENCE TECHNOLOGY: Equipped with artificial intelligence technology, automatic bowing pattern window cleaning reduces manual intervention in autonomous planning.
