Remote Control

The Remote Control lets you conveniently control Roomba’s functions. You can use it to turn Roomba on and off and steer it around your room without bending down. It also gives you remote access to these commands:

iRobot Vacuum Cleaner Remote Control

  • SPOT Roomba spirals approximately 1 metre in diameter and then spirals back to where it started, intensely cleaning a local area.
  • CLEAN Roomba automatically calculates the room size and adjusts its cleaning time appropriately.
  • Dock Roomba attempts to dock on the Home Base™, if present.

How to use the Lighthouse mode?

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

You can use Lighthouses and Virtual Walls at the same time. However, please avoid placing them too close to each other, to the Home Base or to furniture that could block the invisible beams. Otherwise, Roomba might not recognise the Lighthouses or be able to return to its Home Base
