Roborock Customer Service Center - Technical Support

A:
1. Please check that the machine is powered on as scheduled cleaning is ineffective when it is
powered off.
2. Please check that the battery capacity is higher than 20% as the scheduled cleaning is
ineffective when the battery capacity is lower than 20%. It is recommended to keep the machine
on the dock charger and work in standby mode.
3. Please check that the cleaning timer is correctly set; for example, if it is set to "Once", the
setting will not be effective after being executed once, or if it is set to "Workday" and the current
day is a weekend day, scheduled cleaning will also be ineffective.
23. Q: Why can't the firmware be updated to the latest version in one go?
A: The firmware update involves a key update package. It means that when updating from
version A to version C, version B cannot be neglected to check version C updates. Updates
should be carried out in the order of A->B->C, rather than A->C.
24. Q: Why can't the app map be updated? (Updated on August 10, 2018)
A: 1. An Internet connection is essential for obtaining the map of the Mi Home robotic vacuum
cleaner. The map may not be refreshed successfully in poor network environments.
2. The map of the Mi Home robotic vacuum cleaner can be obtained only when the cleaner
works within the Wi-Fi coverage. The map may not be refreshed successfully when the machine
itself is located underneath a sofa or far away from your router.
3. Domain name resolution of the map server is not well supported by some routers and
operators, meaning that refreshing the map always fails. Roborock will promptly offer a solution
to resolve this technical problem. The customer service center can try to help a user to change
the DNS of the router to 114.114.114.114 to test the effectiveness.
If the problem persists, the customer service center can refer the user to the technical support
team.
Exception
: The cleaner is connected via hotspots. The maps can be displayed correctly in the
Mi Home app, but occasionally the maps cannot be display when connected via a router.
Understand the broadband operator of the user. Typical broadband operators such as China
Unicom and China Telecom don't have such a problem. But some smaller operators such as
Great Wall, Broad Netcom, etc. are not very stable, so sometimes the map cannot be displayed.
It is recommended that the user adjusts the MTU in the router settings to 1300, because the
larger the MTU, the longer the delay to transmit a data packet. The larger the MTU, the greater
