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.

After reset, the password will become “last 4 digits of SN” + ”verification code(6 upper case letters)”.

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.

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.
