Possible reasons for not being able to enter the network configuration mode on the RS2 may include:

1. The RS2 is currently engaged in a mapping or cleaning task.

2. There might be an internal error within the RS2's system.

To resolve this issue, we recommend following these steps:

1. If you have attempted to enter the network configuration mode multiple times without success, try restarting the RS2.

2. Wait for the indicator light on the RS2 to rotate and change to a light yellow color before attempting any further operations.

If the problem persists or if you encounter any further difficulties, please don't hesitate to reach out to our customer support for additional assistance.

Please follow the steps below:

1. Check if the RS2 is turned on: Press and hold the start button for 2 seconds. After 30 seconds, observe if the four-color indicator light of the device rotates and changes to a light yellow color, indicating that the device is turned on and functioning properly.

2. Verify if the RS2 lost contact during cleaning: If the robot loses contact with the docking station during cleaning, it may be due to the distance between them being too far. This temporary loss of connection does not affect the robot's normal operation. Once the connection to the docking station is restored, the RS2 will continue operating as usual.

3. Address internal errors: If the indicator light on the RS2 flashes red, it indicates an internal error in the robot's system. In such cases, press and hold the power button to restart the device. This can help resolve the internal error and restore normal functionality.

4. Address network fluctuations: If you experience network fluctuations, it may be helpful to restart the docking station. To do this, unplug the power supply, wait until the station screen is completely turned off, and then reconnect the power supply. This can help stabilize the network connection and ensure proper communication between the RS2 and the docking station.

If you continue to encounter issues or have any further concerns, please don't hesitate to reach out to our customer support for further assistance.

RS2 has four cleaning modes: [Vacuum Before Mop], [Vacuum While Mop], [Vacuum Only], and [Mop Only].

The RS2 can identify and avoid obstacles such as power cords, scales, trash cans, socks, shoes, slippers, and so forth.

After sweeping has accumulated for more than 30 minutes, reverse entangled hair cleaning will be triggered at the end of the task to reduce the entanglement.

Please follow the steps below:

1. If you are using the device for the first time or if it hasn't been used for a long time, switch on the power mode for about 3 minutes.

2. Remove the clean water bucket and clean the pipe under the bucket in case of blockage. 

3. After clearing the blockage, fill the pipe with water and switch on the self-cleaning mode to see if the water goes down.

4. If it does and the problem persists, the clean water sensor may be broken.
