Installation

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. If using this 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 major obstacles. The robot will be able to clean by itself in future uses.

Using the robot

1. Place the charging dock against the wall on a flat surface and plug it into the mains power.
   
   Note:
   • The charging dock should have more than 0.5m (1.6ft) of clearance on each side, and more than 1.5m (4.9ft) in the front.
   • If the power cable is 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.
2. 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 stick the enclosed double-sided tape to the floor. Place the dock onto the double-sided tape to secure it in place.
   
   Note:
   • Use of the double-sided tape to secure the charging dock is optional.
   • When necessary, remove the double-sided tape slowly to reduce residue glue.
3. Power on and charge.
   Press and hold the button to turn on the robot. When the power indicator lights up, place the robot onto the charging dock to begin charging. The robot uses a high-performance lithium-ion rechargeable battery. To maintain peak battery performance, always keep the robot charged.
   
   Note:
   The robot will not turn on when the battery is low. Place the robot directly onto the charging dock to begin charging.

Instructions for use

On/off

Press and hold the button to turn on the robot. The power indicator will turn on and the robot will enter Standby mode. If the robot is in Sleep mode, press and hold the button to turn it off and end the current cleanup.
Note:
The robot cannot be turned off when it is charging.

Start cleanup

Press the button to start cleaning. Once started, the robot will plan its cleaning route based on its scan of the area. It cleans along the edges of a zone first and then moves in a Z-shaped cleaning route to cover the internal area efficiently and thoroughly.

Note:

• Cleaning cannot start if the battery level is too low. Allow the robot to charge before restarting cleanup.
• Tidy away any cables on the ground (including the power cable of the charging dock) before cleaning to avoid losing power or damaging either the robot or the connected device.
• If a cleanup finishes within 10 minutes, cleaning repeats by default.
• If the battery runs low before cleanup is complete, the robot will carry out a top-up charge before resuming cleanup from where it left off.

Pause

When the robot is cleaning, press any button to pause it. Then press the button to continue cleaning or the button to return it to the charging dock and stop the cleaning cycle.
Note:
Placing a paused robot on the charging dock manually will end the current cleanup.

Sleep

If the robot is paused for over 10-minutes, it will go to sleep, and its power indicator will flash slowly. Press any button to wake it back up.
Note:

• The robot will not go to sleep when it is on the charging dock.
• The robot will automatically shut down if left in sleep mode for more than 12 hours.

Charging

Auto: After cleaning, the robot will automatically return to the charging dock to recharge.
Manual: In Pause mode, press the button to send the robot back to the charging dock.
The power indicator will flash slowly as the robot charges.
Note:
If the cleaning cycle was started away from the charging dock and the robot could not return to the dock after cleaning, it will instead return to its starting point. Place the robot directly on the dock to recharge it.

Error

If an error occurs while the robot is cleaning, the power indicator will flash red quickly, and you will hear a voice alert. See "Troubleshooting" for resolution options.
Note:

• The robot will go to sleep automatically if left in an Error state for over 10-minutes.
• Placing the robot on the charging dock in an error state will stop the current cleanup.

Reset WiFi

If your phone cannot connect to the robot because you have changed your router configuration, forgotten your password, or any other reason, open the top cover to see the WiFi indicator light, then press and hold the Spot Cleaning button and the Recharge button until you hear the "Resetting WiFi" voice alert. When the WiFi indicator light flashes slowly, the robot has entered network configuration mode.
Note:
If the robot is left connecting to the network for over an hour, its WiFi will be disabled. Reset WiFi before attempting reconnection.

Spot Cleaning

In Standby or Pause mode, press and hold the button to start spot cleaning. This mode is used to clean a 1.5m x 1.5m square area centered on the robot. After cleanup, the robot will return to the center of the square.

Note:
Starting spot cleaning in pause mode will stop the current cleaning cycle.

Selective Room Cleaning

Select specific rooms for cleaning in the app. In this mode, the robot will only clean the selected rooms.

Note:

• A full map must be created and Map Saving mode switched on before this function can be used.
• After cleaning starts, the robot may move beyond the defined areas. Make sure there are no obstacles preventing the robot's access to the target rooms.

Scheduled Cleaning

Use the app to set start times for scheduled cleanups.
The robot will return to the charging dock after each cleanup.

Zone Cleaning

Use the app to draw a specific zone for the robot to clean.
Note:
While cleaning the designated zone, the robot may move outside zone borders.
Make sure that there are no cables or obstacles placed close to the cleanup zone.

Pin n Go

Use the app to set a destination for the robot to go to.

Cleaning mode

Use the app to choose from Quiet, Balanced, Strong, or MAX modes. The Balanced mode is the default.

Do Not Disturb (DND) mode

In DND mode, no cleanups will start, no voice alerts will play, and the power indicator will dim. DND Mode is set from 22:00 to 08:00 by default and can be disabled or modified in the app.

Virtual No-go Zone and Invisible Wall

The app can be used to draw Virtual No-go Zone and Invisible Wall to keep the robot from entering the areas you define.
Note:

• "Map Saving Mode" must be turned on in the app to use virtual No-go Zone.
• Virtual No-go Zone and Invisible Wall should only be used to customize the cleaning area. They should not be used to isolate hazards.
• Moving the robot manually or making signifcant changes to the home environment may cause the loss of virtual No-go Zone and Invisible Wall.
