Cleaning pattern strange and miss areas

Its cleanjng in circular pattern and missing areas within a room

Hi,

Please follow the steps below to troubleshoot:

1. **Narrow area is inaccessible**:
- If the robot encounters a confined space, it may not be able to enter for cleaning. Please make sure to enter the cleaned space at least 2 cm larger than the width of the robot so that the robot can pass smoothly.

2. **Ultrasonic Carpet Recognition**:
- In mopping mode, some robots equipped with ultrasonic carpet recognition may recognize the carpet and choose not to enter the area for cleaning. Please consider removing the carpet before performing a cleaning test.

3. **Map overlay causes abnormal positioning**:
- If the bot's maps overlap, it can lead to misalignment, which can lead to missed scans. In this case, try remapping or restoring a previously saved map to ensure that the bot correctly recognizes the environment.

4. **Entrance Ground Obstacles**:
- If there is an obstacle such as a woolly carpet or power lines at the entrance to the area, the robot will avoid the obstacle and will not be able to enter the area. Please remove these obstacles before cleaning so that the robot can enter the cleaning area smoothly.


If the above troubleshooting is ineffective, please contact support.na@dreame.tech, share the device with the  customer service, reproduce the problem and upload the sweeper log for troubleshooting.
