Important Information
1. Tidy cables and loose items from the
ground and move any unstable, fragile,
precious, or dangerous items to prevent
personal injury or property damage due
to items becoming tangled in, struck by,
or knocked over by the robot.
2. When using the robot in a raised area,
always use a secure physical barrier to
prevent accidental falls that may result in
personal injury or property damage.
Wipe the floor of the area where the charging
dock will be placed with a dry cloth, then
secure the dock in place using double-sided
tape at the bottom of the dock.
Note: When necessary, remove the double-sided adhesive
tape slowly to reduce residue glue.
Press and hold the button to power on
the robot. When the power light goes on,
place the robot on the dock to charge. Make
sure the charging dock power indicator
turns off and a “charging” voice alert sounds.
To maintain the performance of the high-
performance lithium-ion rechargeable battery
pack, keep the robot charged.
The robot may not turn on when the battery is low. In
this case, place the robot directly onto the dock to charge.
Note:
Power on and charge
the robot
Note: When using the robot for the first time, follow it
throughout its whole cleaning route and watch for potential
problems. The robot will be able to clean by itself in future uses.
Keep the Charging Dock on a level surface,
flat against a wall. Connect the power cable
to the Charging Dock and tidy cables from
the floor. To ensure a better user experience
of the mobile app, place the Charging Dock
in an area with good WiFi coverage.
B1-1 More than 0.5m (1.6ft)
B1-2 More than 1.5m (4.9ft)
After fixing the Charging Dock in place, use a
dry cloth to clean the area where the Moisture-
Proof Mat will be located. Peel off the outer
layer of the double-sided tape attached to the
bottom of the Moisture-Proof Mat, and stick
the mat to the ground as shown.
Notes:
• Always place the Moisture-Proof Mat on wooden floors.
• Peel the double-sided tape slowly to minimize residual adhesive.
• The Moisture-Proof mat attaches best to smooth surfaces.
• Allow at least 0.5m (1.6ft) of clearance on each side, and
more than 1.5m (4.9ft) in front of the Charging Dock.
• If the power cable hangs vertical to the ground, it may
be caught by the robot, causing the Charging Dock to be
disconnected.
• The Charging Dock indicator is on when the Charging Dock
is electrified, and off when the robot is charging.
• Do not place the Charging Dock in places that are directly
exposed to sunlight, or block the Location Beacon. Otherwise
the robot may not be able to automatically return to the
Charging Dock.
Notes:

• Wash the VibraRise mop cloth after each use, and regularly
empty the water tank of unused water.
• Remove the VibraRise mop cloth mount when not mopping.
The water tank can stay in place.
When the robot returns to the dock after
cleaning, press the latches on both sides,
and slide the VibraRise mop cloth mount
backwards to remove it.

• Do not use hot water as this may cause the tank to deform.
Slide the water tank into the robot until you
hear it lock with a click.
B4-3—Reinstall the water tank
Slide the VibraRise mop cloth mount
forwards under the water tank. A click
indicates that it is locked in place.

stops dripping. Insert it into the bottom
along the attachment slot and stick it firmly
in place.

Press the button to start cleaning. The
robot will plan its cleaning route according
to its scan of the room. It splits a room into
zones, first draws out zone edges, and then
fills the zone in a zigzag pattern. In so
doing, the robot cleans all zones one by
one, efficiently cleaning the house.

to the starting point and enter Standby mode.
Press the button to start spot cleaning.
Cleaning range: The robot cleans a 1.5 m
(4.9 ft) x 1.5 m (4.9 ft) square area centered
on itself.
Spot Cleaning
Note: Placing a paused robot on the dock manually will end
the current cleanup.
When the robot is running, press any
button to pause it, press the
button to
resume cleaning, and press the
button to
send it back to the dock.
Pause
Notes:
• To allow the robot to automatically vacuum and return to
the dock, start the robot from the dock. Do not move the
dock during cleaning.

robot to charge before starting the cleanup.
• If cleaning is completed in less than 10 minutes, the area
will be cleaned twice.
• If the battery runs low during the cleaning cycle, the robot
will automatically return to the dock. After charging, the
robot will resume where it left off.
• When the VibraRise mop cloth mount is attached, the robot
will retract it when cleaning the carpet. You can also set the
carpet as a no-go zone in the app to avoid it.
• Before starting each mopping task, make sure that the
VibraRise mop has been properly installed.
If the robot is paused for over 10 minutes, it
will go to sleep, and the power indicator will
flash every few seconds. Press any button
to wake the robot up.

Common Issues
Unable to power on
• The battery level is low. Put the robot on the charging dock and charge it before use.
• The battery temperature is too low or too high. Only use the robot within the range of 4-40°C (39-104°F).
Unable to charge
• Check the power indicator light turns on and that both ends of the power cable are properly connected.
• If contact is poor, clean the contact areas on the charging dock and the robot.
Slow charging
• When used at high or low temperatures, the robot will automatically reduce its charging speed to extend battery life.
• The charging contacts may be dirty. Wipe them with a dry cloth.
Unable to dock
• There are too many obstacles near the charging dock. Move it to an open area.
• The robot is too far from the charging dock. Place it closer and retry.
Abnormal behavior • Restart the robot.
Noise during
cleaning
• The main brush, side brush, main wheels, or omnidirectional wheel may be jammed. Turn off the robot and clean them.
• VibraRise system abnormal. Check for jammed objects.
Unable to
connect to WiFi
• WiFi is disabled. Reset the WiFi and try again.
• The WiFi signal is poor. Move the robot to an area with good WiFi reception.
• Abnormal WiFi connection. Reset the WiFi, download the latest mobile app, and retry.
• The current Roborock robot is not supported. You can find supported models in the app.
• Unable to connect to WiFi abruptly. There may be an error with your router settings. Contact Roborock customer
service for additional support.
Problem Solution
Scheduled cleaning
is not working
• Keep the robot charged. Scheduled cleaning can only begin when the battery level is above 20%.
Poor cleaning ability
or dust falling out
• The dustbin is full and needs emptying.
• The filter is blocked and needs cleaning.
• The main brush is jammed and needs cleaning.
13
Common Issues
Is power always being drawn when the
robot is on the charging dock?
• The robot will draw power while it is docked to maintain battery performance, but power
consumption is minimal.
Does the robot need to be charged
for at least 16 hours the first three
times it is used?
• No, the robot can be used any time after it has been fully charged.
Problem
Solution
No or little water during
mopping
Cleaning does not
resume after recharging
• Check whether there is water in the water tank and use the mobile app to set the scrub
intensity or check the manual for full instructions on how to correctly install the mop cloth
and mop cloth mount.
• Make sure that the robot is not in DND mode. DND mode will prevent cleanup. When cleaning a
space requiring a top-up charge, if the robot was placed manually on the charging dock before it
returned to the dock automatically, it will not be able to continue cleanup.
The robot has begun to
miss certain spots
It takes a long time to fill the water tank
• The wall sensor or cliff sensors may be dirty. Wipe them with a soft dry cloth.
• The filter may be blocked and need cleaning.
The robot cannot return to the
charging dock after spot cleaning or
when it has been moved manually
• After spot cleaning or a significant position change, the robot will re-generate the map. If the
charging dock is too far away, it may not be able to return to recharge and must be placed
on the charging dock manually.
