How to identify parts of your robot

Assembling and charging robot

Remove excess clutter and cables on the floor before cleaning.

Quick Assembly

1. Installation of side brushes
   Turn the main unit over. Attach the side brush to its color-matched post and press down until they fit into place.
   
2. Filter installation
   Robot comes with filter installed. Before use, remove dustbin from robot, pull up lid of dustbin and make sure filter is installed well. Ensure dustbin lid is securely closed and place back dustbin onto robot. When using the mopping function, open the tank lid, fill the water tank with cool tap water, and securely close the lid.
   
   Please do not add any detergent into the water tank to prevent potential clog.
3. Setting up self-emptying base
   1. Place the self-emptying base flat against the wall on a level surface. If there is any charging base for other robot vacuum cleaners in the room, please put it away before use of our self-emptying base to avoid mismatching.
   2. Place the self-emptying base in an area covered with wireless network signal to ensure stable network connection of the robot and proper function of the App. Store the excess cables into the slot at the back of the charging base to avoid affecting the proper function of the robot vacuum.
   3. Plug the power plug into a power outlet.
