How to use the Lighthouse mode

Simply place a Lighthouse in the doorway with the logo facing forward. When it has completed the first room the Lighthouse will help Roomba navigate around your home allowing it to clean room-to-room. When Roomba has completed cleaning, the Lighthouse will direct Roomba back to its Home Base for recharging.

You can use Lighthouses and Virtual Walls at the same time, but avoid placing them

too close to each other, to the Home Base, or to furniture that could block the invisible beams. Otherwise your Roomba might not recognize the Lighthouses or be able to return to Home Base.

How to use the Virtual Wall mode

In Virtual Wall mode, the Lighthouse creates an invisible barrier that your Roomba won’t cross. It automatically turns off when your Roomba is turned off.

Simply place the Virtual Wall Lighthouse in the center of the doorframe. Unlike a Virtual Wall, a Virtual Wall Lighthouse features a range selector that you can use to adjust the length of the barrier – up to 8 feet (2 meters) – (a longer range will drain the

battery faster).

Battery storage and charging

Your Roomba is powered by a rechargeable battery. Before using your Roomba for the first time, you’ll need to charge the battery overnight.

•Make sure your Roomba is fully charged before each cleaning cycle.

•For maximum battery life, always store your Roomba plugged in.

•When your Roomba is on the Home Base, make sure the Home Base power light is on.

•If you return your Roomba to the Home Base / battery charger after leaving

it off for a long time, it will start a special Refresh Charge mode and the battery indicator will pulse quickly. If possible, don’t interrupt the Refresh Charge mode.

•For long-term storage, fully charge the battery, remove, and store it in a cool, dry place.

How to remove your battery

If you won’t be using your Roomba for an extended period, we recommend that you remove the battery. To access the battery, turn Roomba over and remove the two screws that hold Roomba’s battery cover in place.

78002, 770 specifications

The iRobot 770 and 780 series represent a significant advancement in robotic vacuum technology, combining intelligent design with powerful performance to provide an effective cleaning solution for modern households. These models are equipped with a variety of features that enhance their functionality and ease of use, making them a popular choice among consumers seeking efficient home maintenance.

One of the hallmark features of the iRobot 770 and 780 is the advanced iAdapt navigation system. This technology allows the robot to effectively map its surroundings, enabling it to clean every corner of a room while avoiding obstacles. The robot uses a series of sensors to detect dirt and debris, adapting its cleaning path as necessary to ensure maximum coverage. This intelligent navigation system also helps the robot to efficiently navigate around furniture and other obstacles, ensuring a thorough clean without getting stuck.

Both models boast a powerful three-stage cleaning system that includes agitation, extraction, and suction. This robust cleaning system is designed to tackle a variety of surfaces, from hardwood floors to carpets, ensuring a deep clean on both types of flooring. Equipped with dual rotating side brushes, the iRobot 770 and 780 effectively capture dirt and debris along edges and corners where traditional vacuums may struggle.

Another impressive feature is the dirt detect technology. This enables the robot to identify areas that require more intensive cleaning, such as high-traffic zones. When the robot senses a particularly dirty area, it automatically increases its cleaning effort, ensuring that your home is maintained to the highest standards.

The iRobot 770 and 780 series also offer convenient scheduling capabilities, allowing users to set cleaning times according to their schedules. This makes it easy to ensure that your home is cleaned regularly without needing to manually operate the robot each time. Users can also control the vacuum via a remote, facilitating easy operation from anywhere in the home.

Battery life is another critical characteristic of the iRobot 770 and 780. Both models come with a reliable lithium-ion battery, providing ample runtime for cleaning sessions. When the battery runs low, the robot returns to its charging dock autonomously, ensuring that it is always ready for the next cleaning task.

In summary, the iRobot 770 and 780 represent the pinnacle of robotic vacuum technology, offering a combination of smart navigation, powerful cleaning capabilities, and user-friendly features. These innovations make them indispensable tools for maintaining a clean and tidy home with minimal effort.
