Problem
Manufactured by: Foshan VIOMI Electrical Technology Co., Ltd. (a Mi Ecosystem company)
Address: 2nd Floor, No.1 Building And 4th Floor of No.7 Building, North of Four Xinxi Street, Lunjiao, Shunde, Foshan, Guangdong, P.R. China
Solution
As the Vacuum-Mop will re-generate a
map aer fixed-point cleaning or being
displaced by a long distance, it may fail to
locate charging dock for charging. In such
case, place the machine onto charging
dock manually.
Make sure there is sufficient spaces
around charging dock, and there is no dust
or blockage on the surface of electrode of
charging dock.
Make sure the machine has been
connected to the network, as disconnec-
tion from network will fail sync and
scheduled cleaning task.
Make sure the machine is connected to
network successfully, and always within
coverage of Wi-Fi.
Make sure both charging dock and main
machine are within coverage of Wi-Fi and
good signals, and then reset Wi-Fi
connection for pairing by following the
instructions in the manual.
