1. Introduction
The iRobot Roomba 770 Robotic Vacuum Cleaner is designed to provide automated cleaning for your home. It effectively removes dirt, dust, pollen, allergens, and pet hair from various floor types, including carpets, hardwood, tile, and linoleum. Featuring iAdapt Navigation, a 3-Stage Cleaning System, and Dirt Detect Series II technology, the Roomba 770 adapts to your home environment to maximize cleaning efficiency.
This manual provides detailed instructions for setting up, operating, and maintaining your Roomba 770 to ensure optimal performance and longevity.
2. Setup
2.1 Unpacking and Initial Charge
Carefully remove all components from the packaging. Place the Home Base charging station against a wall in an open, uncluttered area. Ensure there is at least 1.5 feet (0.5 meters) of clear space on either side of the Home Base and 4 feet (1.2 meters) in front of it. Plug the Home Base into a power outlet. Place your Roomba 770 onto the Home Base to begin its initial charge. The robot will automatically return to its Home Base to recharge after each cleaning cycle.

2.2 Virtual Wall Technology
The Roomba 770 utilizes Virtual Wall technology to define cleaning boundaries. Virtual Walls create an invisible barrier that the robot will not cross, allowing you to restrict cleaning to specific rooms or areas. Place Virtual Wall units in doorways or other areas you wish to block off. Ensure the Virtual Wall is powered on and positioned correctly to create the desired barrier.

3. Operating Instructions
3.1 Starting a Cleaning Cycle
To start a cleaning cycle, simply press the 'CLEAN' button located on the top of your Roomba 770. The robot will begin cleaning and automatically adjust its cleaning patterns based on your home's layout and floor types. The self-adjusting cleaning head ensures effective cleaning across carpets, hardwood, tile, and linoleum floors.

3.2 Scheduling Cleaning
The Roomba 770 features on-board scheduling, allowing you to program cleaning sessions up to seven times per week. This ensures your home is cleaned even when you are not present. Refer to the detailed scheduling instructions in the full manual for setting specific times and days.
3.3 Spot Cleaning Mode
For smaller, concentrated messes, use the Spot Cleaning mode. Place the Roomba 770 directly on the soiled area and press the 'SPOT' button. The robot will perform a focused, spiral cleaning pattern to thoroughly clean the localized mess.
3.4 Remote Control Operation
The included remote control allows you to manually steer the Roomba 770, turn it on or off, and initiate regular or spot cleaning cycles. This provides convenient control over the robot's movement and functions.

3.5 Navigation and Obstacle Avoidance
The Roomba 770 uses iAdapt Responsive Cleaning Technology, monitoring its environment over 60 times per second with multiple sensors. This allows it to navigate around furniture, clean under beds and other hard-to-reach areas, and follow walls and baseboards for comprehensive coverage. Cliff-detection sensors prevent the robot from falling down stairs or other drop-offs.

4. Maintenance
4.1 Emptying the AeroVac Bin
The Roomba 770 features an AeroVac 2 bin designed to hold large quantities of hair, lint, and other debris. The robot is equipped with a full-bin indicator light that illuminates when the bin needs to be emptied. Regularly empty the bin to maintain optimal cleaning performance.
4.2 Cleaning HEPA Filters
The two HEPA filters in your Roomba 770 capture fine dust particles, minimizing dust recirculation in your home. These filters should be cleaned regularly and replaced periodically to ensure efficient air filtration. Refer to the full manual for instructions on how to remove, clean, and replace the HEPA filters.
4.3 Brush Maintenance
The 3-Stage Cleaning System relies on a spinning side brush and two counter-rotating brushes to agitate, brush, and suction debris. Periodically inspect and clean these brushes to remove tangled hair or debris that may reduce cleaning effectiveness. Instructions for brush removal and cleaning are provided in the comprehensive manual.
5. Troubleshooting
If your Roomba 770 is not performing as expected, consider the following common troubleshooting steps:
- Check the Dust Bin: Ensure the AeroVac bin is not full. Empty it if necessary.
- Inspect Brushes: Remove and clean the main brushes and side brush for any tangled hair or debris.
- Clean Sensors: Wipe down the cliff sensors and bumper sensors to ensure they are free of dust and debris.
- Verify Charging: Ensure the robot is properly docked on the Home Base and the charging indicator is active.
- Battery Life: If the robot's run time is significantly reduced, the battery may need replacement.
