Dual-Layer Debris Collection Device for Autonomous Cleaning Robots

The debris collection system is divided into two distinct segments: a cleaning pad portion for collecting larger debris through contact with the floor surface, and a vacuum bag portion for trapping smaller debris through airflow. This segmentation allows each component to be optimized for its specific function, enabling efficient simultaneous collection of different debris sizes while maintaining manageable system complexity through modular design.

The collected debris is extracted from the cleaning environment and contained within sealed containers (cleaning pad and vacuum bag). The entire debris collection device can be removed as a unit from the autonomous cleaning robot, allowing users to dispose of debris without contacting it directly. This extraction principle eliminates user exposure to potentially harmful debris while maintaining simple operational procedures.

The debris collection device achieves multi-functionality by integrating two collection mechanisms: the cleaning pad portion contacts the floor surface to collect larger debris, while the vacuum bag portion uses airflow to trap smaller debris. Both portions work simultaneously within a single device, enabling the system to handle various debris sizes and types effectively. The universal design allows the same device structure to accommodate different cleaning needs without requiring multiple separate systems.
