L40 vacuuming in circles

My robot is not vacuuming properly. It goes in circles and random patterns.  I have done a hard reset and the firmware is up to date.  Any help on fixing this would be great!

Help This is frustrating!  My robot is not old and I just want it to vacuum a room properly.

Hi,


Below is a detailed explanation of the first mapping behavior and targeted troubleshooting steps for daily route confusion to help resolve the problem:

1. First Mapping Process (Explanation)
During the first mapping, the robot needs to explore the indoor terrain comprehensively. To cover more areas, it will take a more tortuous route. Once the map is successfully built and saved, the subsequent cleaning routes will return to normal and become more efficient—this is a normal initial adaptation process.

2. Troubleshooting for Daily Route Confusion
If the robot experiences route confusion during everyday use, please check it according to the following steps:
a. **Preparation before cleaning**:
- Before cleaning, please tidy up any scattered items on the floor, such as drag strips, toys, slippers, etc. This helps the robot avoid frequent collisions during cleaning, thus reducing the likelihood of route confusion.

b. **Checking in Cleaning**:
- Inspect the drive wheels at the bottom to make sure there are no foreign objects stuck, dirty, or greased. This situation will cause the robot to move abnormally, affecting the cleaning effect.

c. **Collision during cleaning**:
- If the robot collides frequently during cleaning, it may briefly move along the edges and then resume bow-shaped cleaning. This is to readjust its sweeping mode to ensure more efficient cleaning.

d. **Frequent Confusion**:
- If the robot often has chaotic routes, it is recommended to update the robot's firmware to the latest version. In addition, consider resetting the map and restarting the map to improve the accuracy and efficiency of the cleanup.
