Installation

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.

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.

Position the charging dock

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)

Notes:

• 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.

Secure the charging dock with the adhesive tape

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.

Attach the Moisture-Proof Mat

After fixing the Charging Dock in place, use a dry cloth to clean the area where the MoistureProof 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.

Power on and charge the robot

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.

Note: The robot may not turn on when the battery is low. In this case, place the robot directly onto the dock to charge.

Mopping

Note: To prevent excessive dirt buildup during first-time use, floors should be vacuumed at least three times before mopping.

B4-1—Remove the water tank

Press the water tank latch and slide the tank backwards.

B4-2—Fill the water tank

Remove the water tank stopper, fill the tank with water, and close it tightly.

Notes:

• To prevent corrosion or damage, only use the Roborock branded floor cleaner in the water tank.
• Do not use hot water as this may cause the tank to deform.

B4-3—Reinstall the water tank

Slide the water tank into the robot until you hear it lock with a click.

B4-4—Install the VibraRise mop cloth

Dampen the mop cloth and wring it until it stops dripping. Insert it into the bottom along the attachment slot and stick it firmly in place.

B4-5—Install the VibraRise mop cloth mount

Slide the VibraRise mop cloth mount forwards under the water tank. A click indicates that it is locked in place.

B4-6—Remove the VibraRise mop cloth mount

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.

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.

B4-7— Risk of injury.

Do not place your finger between VibraRise mop cloth mount and water tank.

Common Issues

Problem	Solution
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.
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.
Scheduled cleaning is not working	Keep the robot charged. Scheduled cleaning can only begin when the battery level is above 20%.
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.
No or little water during mopping	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.
Cleaning does not resume after recharging	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 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.
The robot has begun to miss certain spots	The wall sensor or cliff sensors may be dirty. Wipe them with a soft dry cloth.
It takes a long time to fill the water tank	The filter may be blocked and need cleaning.
