Improves cleaning efficiency: It addresses areas that traditional robots have difficulty cleaning due to terrain limitations, such as balconies and kitchens, allowing for coverage without manual relocation and enhancing cleaning efficiency and automation. Supports multi-scenario use: Can be applied to threshold transitions in balconies, kitchens, bathrooms, and other areas, and can also help robots cross low obstacles such as carpet edges. Completely solves the issue of robots getting stuck on thresholds, the elderly, and others who cannot constantly monitor the device. Facilitates smooth passage over thresholds: By creating a gentle slope that connects thresholds, sliding door tracks, and other height differences, the robot can move freely between rooms without getting stuck, enabling whole-house cleaning.
