iRobot Roomba Virtual Wall Lighthouse Instruction Manual

1. Introduction

The iRobot Roomba Virtual Wall Lighthouse is an accessory designed to enhance the cleaning capabilities of your Roomba robotic vacuum cleaner. It serves two primary functions: creating invisible barriers to restrict Roomba's movement (Virtual Wall mode) and guiding Roomba through multiple rooms for sequential cleaning (Lighthouse mode).

This device is compatible with specific Roomba models: 885, 880, 780, 577, and 570. Please ensure your Roomba model is listed as compatible. Note that some Roomba models, even within the specified series, may not support the Lighthouse function if they were not originally equipped with the necessary wireless communication capabilities.

2. Important Safety Information

• This device is for indoor use only.
• Do not expose the device to liquids or moisture.
• Use only the specified battery type (2 C-size dry cell batteries).
• Do not mix old and new batteries, or different types of batteries.
• Dispose of used batteries properly according to local regulations.
• Keep out of reach of children and pets. This is not a toy.
• Do not attempt to disassemble or repair the device yourself. Contact iRobot support if service is required.

3. Setup

3.1 Battery Installation

1. Locate the battery compartment on the bottom of the Virtual Wall Lighthouse.
2. Open the battery compartment cover.
3. Insert two (2) C-size dry cell batteries, ensuring correct polarity (+/-). Batteries are not included and must be purchased separately.
4. Close the battery compartment cover securely.

3.2 Device Placement

Place the Virtual Wall Lighthouse on a flat surface in the area where you want to control Roomba's movement. Ensure the device is upright and the signal is not obstructed by furniture or walls. For optimal performance, place it near a doorway or at the boundary of the area you wish to restrict.

4. Operating Instructions

The Virtual Wall Lighthouse has a switch to select between two modes: Virtual Wall and Lighthouse.

4.1 Virtual Wall Mode

In Virtual Wall mode, the device creates an invisible barrier that Roomba will not cross. This is useful for confining Roomba to a specific room or blocking off areas you do not want cleaned.

1. Set the switch on the Virtual Wall Lighthouse to the Virtual Wall icon (usually a wall symbol).
2. Place the device at the entrance of the area you want to block. The signal can extend up to 2.4 meters (8 feet).
3. When Roomba approaches the barrier, it will detect the signal and turn away.

4.2 Lighthouse Mode

In Lighthouse mode, the device guides Roomba through multiple rooms, allowing it to clean one room completely before moving to the next. It also prevents Roomba from leaving a room until it has finished cleaning.

1. Set the switch on the Virtual Wall Lighthouse to the Lighthouse icon (often a lighthouse beam symbol).
2. Place the device in a doorway between two rooms you want Roomba to clean sequentially.
3. Roomba will clean the first room, then the Lighthouse will open the barrier, allowing Roomba to proceed to the next room. Once the second room is cleaned, Roomba will return to its Home Base, guided by the Lighthouse.

5. Maintenance

5.1 Cleaning the Device

Wipe the exterior of the Virtual Wall Lighthouse with a clean, dry cloth as needed. Do not use abrasive cleaners or spray liquids directly onto the device.

5.2 Battery Replacement

When the batteries are low, the indicator light on the Virtual Wall Lighthouse may flash or turn off. Replace the batteries promptly to ensure continuous operation.

1. Turn off the device.
2. Open the battery compartment on the bottom.
3. Remove the old C-size batteries.
4. Insert two new C-size batteries, observing correct polarity.
5. Close the battery compartment cover.

6. Troubleshooting

• Device not turning on: Ensure batteries are correctly installed and are not depleted. Replace batteries if necessary.
• Roomba ignoring the barrier/not navigating rooms:
  • Verify that the Virtual Wall Lighthouse is set to the correct mode (Virtual Wall or Lighthouse).
  • Check that the batteries are fresh and properly installed.
  • Ensure there are no obstructions between the device and Roomba.
  • Confirm your Roomba model is compatible and supports the specific function (Virtual Wall or Lighthouse). As noted in the introduction, some models may not have the necessary internal communication hardware for Lighthouse functionality even if they are in the compatible series.
  • Try repositioning the device.
• Short battery life: Use high-quality alkaline batteries. Ensure the device is turned off when not in use.

If problems persist, refer to your Roomba's main instruction manual or contact iRobot customer support.
