Setup
1. Unpacking and Placement
Carefully remove all components from the packaging. Select a suitable location for the AutoWash charging station. Ensure it is placed against a wall, with adequate clear space around it for the robot to dock and maneuver. Avoid placing it near stairs or heat sources.

2. Initial Charging
Place the Roomba robot onto the AutoWash charging station. Ensure the charging contacts align. The robot will begin charging automatically. Allow for a full charge before the first use, which may take several hours.

The Roomba robot automatically returns to its charging station to recharge after completing a cleaning cycle or when its battery is low.
3. App Download and Connection
Download the iRobot Home App from your device's app store. Follow the in-app instructions to connect your Roomba Plus 405 Combo to your home Wi-Fi network and pair it with the app. This will unlock advanced features and control options.

The Roomba Home App provides an intuitive interface for managing your robot vacuum and mop.
Operating Instructions
1. Starting a Cleaning Cycle
You can initiate a cleaning cycle using one of three methods:
- iRobot Home App: Tap the 'Clean' button within the app.
- Voice Assistant: Use a compatible voice assistant (e.g., Alexa, Siri, Google Assistant) with a command like "Hey Google, tell Roomba to start cleaning."
- Robot Button: Press the 'Clean' button located on the top of the robot.
2. Selecting Cleaning Modes
The Roomba Plus 405 Combo offers four distinct cleaning modes, selectable via the iRobot Home App:
- Vacuuming Only: For dry debris removal.
- Mopping Only: For wet cleaning of hard floors.
- Combined Vacuuming + Mopping: Performs both functions simultaneously.
- Mopping After Vacuuming: Completes a vacuuming cycle before initiating mopping.

The iRobot Home App allows users to select from four different cleaning modes to suit their specific needs.
3. Scheduling and Customization
Utilize the iRobot Home App to set cleaning schedules, define specific cleaning areas, and establish no-go zones. The robot's LiDAR navigation system creates a detailed map of your home, allowing for precise and efficient cleaning.

The Roomba Home App enables users to customize cleaning schedules for specific days and rooms, adapting to individual lifestyles.

The app allows users to pinpoint specific areas for cleaning or designate no-go zones on a digital map of their home.
Maintenance
Regular maintenance ensures your Roomba Plus 405 Combo continues to operate effectively. The AutoWash station significantly reduces manual cleaning tasks.
1. AutoWash Station Maintenance
- Emptying Debris: The station automatically collects debris into a sealed bag. Replace the bag when indicated by the app or station light.
- Water Tanks: Periodically check the clean water tank and refill as needed. Empty and clean the dirty water tank to prevent odors and maintain hygiene.
- Mop Pad Cleaning: The station automatically washes and dries the mop pads. Ensure the mop pads are properly attached for effective cleaning and drying.

The transparent design of the water tanks allows for easy visual inspection of water levels, indicating when refilling or emptying is required.
2. Robot Component Cleaning
- Rubber Brushes: The rubber brushes are designed to minimize hair tangles. Regularly inspect and clean them to remove any accumulated hair or debris.
- Edge-Cleaning Brush: Remove and clean the edge-cleaning brush periodically.
- Sensors: Wipe the robot's sensors with a clean, dry cloth to ensure proper navigation.
- Filter: The app will indicate when the filter needs to be checked or replaced.

The rubber brush is engineered to resist hair tangles, simplifying maintenance.
Troubleshooting
If you encounter issues with your Roomba Plus 405 Combo, refer to the following common solutions:
- Robot Not Charging: Ensure the charging contacts on both the robot and the station are clean and free of debris. Verify the power cord is securely plugged into the station and a working outlet. If the issue persists, contact customer support.
- Excessive Noise During Operation: The automatic debris disposal and mop washing functions can generate noise. This is normal. If the robot itself is unusually loud during cleaning, check for obstructions in the brushes or wheels.
- Mop Pads Getting Caught: Ensure there are no loose rugs or obstacles that could interfere with the mop pads. If the mop pads frequently detach, verify they are securely fastened.
- Navigation Errors: Clean all sensors on the robot. Ensure the home environment is well-lit for initial mapping. Remove any temporary obstacles that might confuse the robot.
- App Connectivity Issues: Ensure your Wi-Fi network is stable and the robot is within range. Restart both the robot and your router if necessary.
For persistent issues or error messages not covered here, consult the iRobot Home App for specific troubleshooting steps or contact iRobot customer support.
