Verdict

The BPMIO B20 is a 2-in-1 robot vacuum and mop combo featuring a strong 5500Pa maximum suction power, advanced SLAM-based LiDAR navigation capable of mapping up to 5 floors, and a 120-minute battery runtime. Its key characteristics include a 260ml dustbin with a HEPA filter that captures 99.69% of particles, a 290ml electronically controlled water tank with 3 adjustment levels, and integration with Alexa, Google Assistant, and a 2.4GHz Wi-Fi app. Pro highlights include its strong suction for handling pet hair, precise no-go zone management for up to 34 restricted areas, custom scheduling, and automatic carpet-boost capability. However, notable cons include its limitation to only 2.4GHz Wi-Fi networks and the lack of a self-emptying base station, requiring manual emptying of its relatively small 260ml dust container.
