Roomba 900 series has various settings which allow you to customize how Roomba cleans your home. These settings are available only through the iRobot HOME App.
Cleaning preferences can vary based on your Roomba series and model.
Notes for Cleaning Preferences
Carpet Boost*
Roomba automatically increases its vacuum power on carpet, to provide a deeper clean. On hard surfaces, Roomba reduces its vacuum power to decrease battery consumption while still delivering excellent cleaning performance. Carpet Boost is set to automatic mode by default.
Cleaning Pass**
In most cases, Roomba will remove dirt and debris with just one pass over each area of your home. Two cleaning passes may be particularly helpful in homes with pets or for periodic deep cleaning.
When automatic mode is active, Roomba intelligently chooses to use two or more passes for a single small room or one pass if cleaning a larger space. This setting can be helpful for varying sized spaces. When placed in a smaller room, Roomba can choose to do more cleaning passes without concern for battery depletion.
Automatic cleaning preference is available with the following software versions:
Edge Clean**
After Roomba finishes cleaning the open areas of your floor, it uses “Edge Clean” to ensure that it has cleaned along walls and around furniture legs. If you prefer a quicker clean, you can disable Edge Clean. Edge Clean is set to “On” by default.
If Edge Clean mode is disabled, Roomba may not cover your entire floor.
Behavior When Bin is Full+
Roomba senses when its dust bin is full. There are two options for what Roomba should do when the bin is full.
On: Even if the bin is full, Roomba will continue cleaning until it has covered the entire space. Once the bin is emptied, Roomba is ready for a new cleaning job. This is set to “On” by default.
Off: As soon as the bin is full, Roomba will pause its cleaning job and return to where it started. Once the bin is emptied, press CLEAN to resume.
Notes for Behavior When Bin is Full
If the 
full bin indicator illuminates at any time during a cleaning job, you can always pause the cleaning job to empty the bin and then continue cleaning.
If the full bin indicator is illuminated but the bin does not appear to be full, visit bin care procedure.
