The evolution of navigation technology and the revolution of cleaning efficiency for household floor cleaning robots

From random collisions to laser mapping, the navigation technology of robotic vacuum cleaners is undergoing a qualitative change from "blind cleaning" to "precise planning".

Limitations of Early Navigation Technologies

Inertial navigation robots rely on gyroscopes and accelerometers, with a cleaning path repetition rate of up to 40%, and are prone to getting stuck at the bottom of furniture. Although visual navigation robots can recognize obstacles, their misjudgment rate can reach up to 35% in low light environments.

Breakthrough in navigation through multi-sensor fusion

LDS LiDAR: By rotating the laser head 360 ° to scan the environment, a centimeter level accuracy map is constructed, and the cleaning coverage is increased to 98%. A certain brand model can complete the entire house construction plan in 20 minutes in a 100 square meter space.

DToF time-of-flight sensor: using pulsed laser ranging, the detection distance reaches 10 meters, which is three times higher than infrared sensors and is not affected by strong light interference.

AI visual recognition: By using a front camera and convolutional neural network, it can identify small obstacles such as wires and toys to avoid entanglement. Actual testing shows that its recognition accuracy for obstacles over 5cm is 99%.

Innovative Practice of Clean Technology

Rotating pressure mopping: Using a high-speed rotating mop that rotates 180 revolutions per minute, combined with downward pressure (10N), to remove stubborn stains on the ground. Actual testing shows that its cleaning rate for coffee stains is 40% higher than that of ordinary floor mopping robots.

Automatic dust collection system: The dust box garbage is sucked into the base station dust collection bag through a large suction fan, reducing the frequency of users dumping garbage. A certain brand's dust collection bag has a capacity of 2.5L, which can meet the demand for 30 days of use.

Electrolytic water sterilization: By electrolyzing tap water with electrodes, hypochlorous acid and hydroxyl radicals are produced, with a killing rate of 99.9% against Staphylococcus aureus and Escherichia coli. Actual testing shows that the number of bacteria on the ground decreased by 97% after mopping.

Intelligent upgrade of user interaction

Voice control ecosystem: Supports mainstream voice assistants (such as Xiao Ai and Tmall Genie), and users can specify cleaning areas (such as "cleaning the kitchen") through voice commands.

3D map editing: Through the app, users can customize the cleaning of restricted areas, virtual walls, and cleaning sequence to meet the needs of complex apartment layouts.

Automatic cleaning base station: The base station has mop self-cleaning, drying, and water replenishment functions, achieving a "fully automatic cleaning closed-loop". Actual testing shows that the moisture content of the mop decreases from 85% to 15% after self-cleaning, avoiding the generation of odors.

Every breakthrough in household appliance technology stems from a deep understanding of user needs. From improving energy efficiency to ensuring health, from convenient operation to intelligent interaction, technological innovation is continuously reshaping the quality of life in modern households.
