Hello Wyze Robot Vacuum users,
As you may know, Wyze Robot Vacuum has 4 cliff sensors on its bottom edge. Do you know how the cliff sensors work to avoid falling off the stairs?
Cliff sensors measure the distance between the robot base and the floor, usually by bouncing infrared light off the floor. If there is a sudden increase in the distance to the floor, the amount of reflected light off a surface changes. That means the robot is getting close to a stair edge or something similar, so it will back off to avoid falling over it (hence the “cliff sensor” name).
Why does my vacuum refuse to clean dark carpet?
Sometimes, Wyze Robot Vacuum may not run on certain dark or black-colored surfaces because they’re not reflective enough for the infrared. In this case, the cliff sensors are triggered in the same way as they would be if there were a drop.
Any workaround to disable the cliff sensors?
At present, there is no immediate solution to disable the cliff sensors as they are essential in many homes. It also involves complex underlying navigation algorithms and requires a lot of effort to make changes. A workaround is to tape over the 4 cliff sensors with white/light-colored paper to manually disable them if you have to. Please DO NOT use this workaround if there are any stairs/cliffs in your home.
Keep the cliff sensors clean
Remember to clean the cliff sensors once in a while to ensure optimal performance. To clean the cliff sensors:
- Start by turning your vacuum upside down
- Wipe each cliff sensor opening with a clean dry cloth
- Make sure to clean all four cliff sensors
