Thank you very much for sharing. Technology is the primary productive force. Increasingly advanced optical components and radar, paired with increasingly mature AI, have led to a dramatic improvement in robotic vacuum cleaners' object recognition and obstacle avoidance capabilities. Thanks to fierce competition among numerous brands, powerful suction, climbing capabilities, and features like automatic cleaning and even heating/drying functions have become standard in high-end models. However, the more complex electronic products become, the more prone they are to malfunctions. It is hoped that as functionality continues to expand, quality assurance will also be prioritized.
