Installation

Important Information

• 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.
• 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.

Clearance Requirements:

• B1-1: More than 0.5m (1.6ft) clearance on each side.
• B1-2: More than 1.5m (4.9ft) clearance in front.

Notes:
• 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 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 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.

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 [power 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.

Remove the Water Tank

Press the water tank latch and slide the tank backwards.

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.

Reinstall the Water Tank

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

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.

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.

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.

WARNING

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

Instructions

On/Off

Press and hold the [power button] to turn on the robot. The power indicator will turn on and the robot will enter standby mode. Press and hold the [power button] to turn off the robot and complete the cleaning cycle.

Note: The robot cannot be turned off when it is being charged.

Starting Cleaning

Press the [start 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.

Visual representation of cleaning zones: Zone 1 - Cleaned, Zone 2 - Cleaned, Zone 4 - Next Zone, Zone 3 - In Progress.

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.
• Cleaning cannot start if the battery level is too low. Allow the 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.

Spot Cleaning

Press the [start 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.
