Home Base

Place the Home Base in an open, uncluttered area leaving the following distances around the Home Base:
Always keep the Home Base plugged in and make sure it is in an area with consistent Wi-Fi® coverage to allow Roomba to receive information via the iRobot HOME App.
Note: Roomba ships with a partial battery charge. If you start a cleaning cycle before charging the battery fully, Roomba may return to the Home Base to recharge sooner than it will during future cleaning cycles. To fully charge the battery before the first cleaning cycle, allow Roomba to charge on the Home Base for 3 hours.
Note: Remove excess clutter from floors before cleaning (e.g. clothing, toys, etc.). Use Roomba frequently to maintain well-conditioned floors.

illuminate.
(SPOT) on the robot. Roomba will intensely clean the area by spiraling outward about 3 feet (1meter) in diameter and then spiraling inward to where it started.
, it is programed to complete its cleaning cycle by default. You can adjust this setting under Cleaning Preferences
in the iRobot HOME App.Note: After each use, empty the bin and clean the filter.

The Dual Mode Virtual Wall barrier keeps Roomba in the places you want to be cleaned — and out of the ones you don’t. In between cleaning cycles, you can leave the device operating in its position on the floor. You can set your device to one of two modes to fit your home’s cleaning needs:
Note: Under normal use, batteries will last 8-10 months. If you are not planning on using your Virtual Wall device for an extended period of time and you would like to store it, be sure to switch it to the “Off ” (middle) position.
Virtual Wall Mode: When the switch is in the “up” position (
), the device functions as a Virtual Wall. This means that you can set it to block openings of up to 10 feet (3 meters). It creates an invisible, cone-shaped barrier that only Roomba can see.
Note: This barrier gets wider as it gets further from the device (refer to illustration).

Halo Mode: When the switch is in the “down” position (
), the device creates a protective zone that Roomba will not enter. This prevents Roomba from bumping into items you want to protect (e.g. a dog bowl or vase) or crossing into undesired areas (e.g. a corner or under a desk). The Halo is invisible and reaches approximately 24 inches (60 centimeters) from the center of the device.

To keep Roomba running at peak performance, perform the following care procedures. If you notice Roomba picking up less debris from your floor, then empty the bin, clean the filter and clean the extractors.
| Robot Part | Care Frequency | Replacement Frequency |
| Bin | After each use - | - |
| Filter | Once per week (twice per week in homes with pets) | Every 2 months |
| Full Bin Sensors | Once every 2 weeks | - |
| Front Caster Wheel | Once every 2 weeks | Every 12 months |
| Side Brush Cliff Sensors Charging Contacts iAdapt Localization Camera Floor Tracking Sensor | Once per month | |
| Extractors | Once every 4 months (once every 3 months in homes with pets) | Every 6-12 months |
Note: iRobot manufactures various replacement parts and assemblies. If you think you need a replacement part, please contact iRobot Customer Care for more information.

Roomba will tell you something is wrong with a two-tone distress sound followed by a spoken message. The troubleshooting indicator (
) will also blink. More detailed support and videos, are available through the iRobot HOME App as well as online. If the problem is not resolved, visit www.irobot.com/Roomba900.
Rebooting Instructions
For some errors, rebooting Roomba may resolve the problem. To reboot Roomba, press and hold CLEAN for 10 seconds until all indicators illuminate, then release. When you release the CLEAN button, you will hear an audible tone signifying a successful reboot.
Note: If you use Roomba’s scheduling feature, open the iRobot HOME App after rebooting to confirm that Roomba’s schedule remains intact.
Reduced Power Standby Mode
Roomba consumes a small amount of power any time it is on the Home Base to ensure that it is ready for its next cleaning job as well as to maintain Wi-Fi connectivity. It is possible to put Roomba in a further-reduced power state when not in use. For instructions and more details on this Reduced Power Standby Mode, refer to the iRobot HOME App
Lithium Ion Battery
For best results, only use the iRobot Lithium Ion Battery that comes with Roomba. While Roomba will operate with older-model batteries, its performance will be limited.
Important: Lithium ion batteries and products that contain lithium ion batteries are subject to stringent transportation regulations. If you need to ship this product (with the battery included) for service, travel or any other reason, you MUST comply with the following shipping instructions:
