Ensure there is adequate lighting and that your robot's camera is not obstructed by debris/dust. If none of the above is successful, try starting a cleaning job for a specific room.

Roomba® uses Dirt Detect™ Technology that allows it to focus its cleaning effort in dirtier areas. When your robot finds more dirt than usual concentrated in one (1) area, it will activate Dirt Detect™ and work harder to clean the same area until the sensors detect fewer dirt particles in that particular area.

Imprint™ Smart Mapping Technology allows your robot vacuum to learn and map your home, adapting to your needs. After just one run, you can customize the map by creating rooms and zones so that you can tell your robot to clean or avoid specific areas.

If you get a more affordable model, like Roomba 675 you can expect a lifespan of up to two years. Go to the higher-end, like the iRobot j7+, and our research and testing suggest you can get five years plus of cleaning with proper maintenance.

To start a mapping run, click the Map button on the home screen. The Map button will take you to the Maps list screen where you can start a mapping run by selecting the “+” at the top right corner of the screen or the “Create New Map” card.

How they clean. Robots that use iAdapt® 2.0 Navigation Technology with Visual Localization can systematically navigate your cleaning area, utilizing the camera to identify landmarks to help Roomba® understand its location.

Made by iRobot, these robotic vacuum cleaners use sensors to detect walls and items in a room, becoming smarter the more frequently they clean.

It typically takes three (3) to five (5) cleaning missions or Mapping Runs to generate a fully developed Imprint™ Smart Map that you can then customize and use. Simply select Clean All in the iRobot® HOME APP to have Roomba clean and learn an entire level of your home during the cleaning cycle.

Smart Maps give you the ability to make a selection in the iRobot® HOME App to “Clean All” rooms or to select only specific rooms to clean. If you want Roomba® to clean the entire level of your home as laid out on your Smart Map, please ensure you are selecting “Clean All”.

iRobot says the device can remember up to 10 floorplans, meaning you can “kidnap” it, take it to a new place, and it will learn that one, too. (It will also work with Alexa and the Google Assistant, so you should be able to shout at an Echo Dot for the Roomba to clean a specific room you've just sullied.)

FANUC tells us that a robot in a typical duty cycle application will run 80,000 to 100,000 hours without any failures. This is extraordinary given the amount of work a robot can perform in that amount of time. As with all equipment, there are the usual caveats concerning proper maintenance during the life of the robot.

Most owners believe that running their robot vacuums four times per week is sufficient to keep the floors dust-free. However, if you have children or pets, you should use your robot vacuum more frequently. Daily vacuuming is recommended if you suffer from seasonal allergies.
