Does anyone know if wheel replacements are available for the S4? My left wheel is very difficult to move compared to the right one and I'm getting an internal error when it tries to clean. I see there are replacements for several other models but none of them list the S4 specifically.
Please try the method below:
1. Put the device on the ground, push it aggressively forward&backward for around 10 sec (like using an eraser). You can push it with some force like in the video below:

2. When you feel there's less resistance in the wheels, start cleaning again to see if it works.
Notice:
Manually pushing the device would cause an overheat of the motor. If the resistance is still high after erasing the wheel for 10 seconds, please wait for a while until the motor cools down, and then try it again.
For wheel replacement, would you please reach out to our support team at support@roborock.com(if you are in EU, contact support@roborock-eu.com) so that we can better assist?
