Hello Wyze Robot Vacuum users,
As you know, Wyze Robot Vacuum is equipped with a Laser Distance Sensor/LiDAR SLAM system that provides you with great advantages for room mapping and efficient cleaning with straight-line movements. Do you know how this LiDAR-based SLAM technology works?
How does the WRV build a map and navigate?
The top-mounted LiDAR sensor spins around (6 times/second) and emits a laser in every direction. It measures the reflected light back into the sensor to determine the position and distance (2,016 samples/second) of obstacles. The vacuum uses the data it collects in combination with information from its other sensors, including:
- IMU (Inertial Measurement Unit calculating orientation, rotational changes, and acceleration)
- Drop sensor
- Cliff sensors
- Collision sensors
It gradually builds a map of the room and navigates during cleaning.
What is the logic behind saving and updating the map?
In order to save and update the map, the vacuum MUST start from the charging station and return to the charging station after completing a Quick Mapping or a whole home cleaning without user intervention, and the position of the charging station must remain unchanged.
What is the logic of resuming Cleaning after recharging?
When the size of the remaining area to clean is >= 25m^2 (269sqft), the vacuum will resume cleaning after recharging back to 60%
When the size of the remaining area to clean is < 25m^2 (269sqft), the vacuum will resume cleaning after recharging back to 40%
You can always cancel the remaining task during charging
Is the laser harmful?
Nope! The LIDAR sensor is not harmful to the naked eye. Wyze Robot Vacuum’s LiDAR sensor is certified as a ‘Class 1’ laser product that is not harmful to humans and animals. We also designed the disc to stop spinning after the sensor shuts down to further prevent any exposure to the sensor’s light.
