Maintenance
The AutoWash Dock simplifies maintenance, ensuring your robot and home stay clean with minimal effort.
AutoWash Dock Functions
- Self-Emptying: The robot automatically empties its dustbin into a sealed bag in the dock, holding up to 75 days of debris.

Mop pads are kept clean and refreshed throughout the cleaning process by the dock.
Dustbin and Filter Care
While the dock handles most emptying, periodically check the robot's internal dustbin and filter for any remaining debris or hair. Clean or replace the filter as recommended by the app to maintain optimal suction.
