Understanding Cleaning Modes

The Roomba Combo offers versatile cleaning modes:

Vacuum Only: The robot will only vacuum.
Mop Only: The robot will only mop.
Vacuum & Mop: The robot will perform both functions simultaneously.
Vacuum then Mop: The robot will first vacuum the entire area, then return to mop.

The DualClean rotating mop pads and SmartScrub system provide enhanced cleaning. The mop pads automatically lift when the robot detects carpets or rugs, ensuring seamless multi-surface cleaning without wetting carpets.

Customizing Cleaning Preferences

Through the iRobot Home app, you can fine-tune your cleaning experience:

Suction Levels: Adjust between 4 levels of suction power to suit different floor types and cleaning needs.
Cleaning Zones: Define specific areas for targeted cleaning or set up 'Keep Out Zones' to restrict the robot from certain areas.
SmartScrub: Activate SmartScrub for a deeper clean on stubborn messes, applying downward pressure and repeated passes.

4. Maintenance

Regular maintenance ensures optimal performance and longevity of your iRobot Roomba Combo. Always power off the robot and unplug the AutoWash Dock before performing any maintenance.

AutoWash Dock Maintenance

Auto-Empty Bin: The dock automatically empties the robot's dustbin for up to 75 days. Periodically check the dock's disposable bag and replace it when full.
Water Tanks: The dock features clean and dirty water tanks. The clean water tank needs to be refilled regularly (approximately every 4 weeks based on typical usage), and the dirty water tank should be emptied and rinsed.
Mop Pad Refreshing & Drying: The dock automatically washes and dries the mop pads. Ensure the pad washing area on the dock is clean and free of debris.

Robot Component Cleaning

Dustbin and Filter: Even with auto-empty, it's recommended to manually clean the robot's dustbin and tap out the filter periodically. Replace the filter every 2-3 months, or as needed.
Brushes: Remove and clean the multi-surface rubber brushes and the side brush regularly. Remove any hair or debris wrapped around them.
Sensors and Charging Contacts: Wipe the robot's sensors (cliff sensors, wall-following sensor) and charging contacts with a clean, dry cloth to ensure proper operation.
Mop Pads: While the dock washes them, it's good practice to occasionally hand-wash or machine-wash the mop pads for a deeper clean.
