Roomba Not Picking Up Dirt? Here’s What to Check
Work through the mode, bin, filter and brushes when dry debris stays on the floor.
Poor pickup and missed coverage are different problems. First check whether the robot passed over the debris. If it never reached the area, start with the map and access rather than suction.
These instructions focus on newer Roombas that use the Roomba Home app. Older robots using iRobot Home (Classic) have different controls and care instructions.
Is the Robot Performing the Right Task?
Check the robot’s bin even if it has an AutoEmpty dock. Where the robot uses paired rollers, fit each roller in its correct position and inspect the roller ends for trapped hair.
Select a dry vacuuming task for a simple test. A mop-only job is not a reliable way to judge the vacuum’s pickup.
Is the Robot’s Dust Storage Clear?
Stop the task and inspect the robot’s dustbin or debris container. Empty it using the prescribed method and check the accessible inlet for a clump of hair.
A larger dock container can still have room while the robot’s smaller container is blocked. If debris repeatedly stays in the robot after docking, investigate collection separately.

Does the Filter Need Attention?
Do not wash a Roomba filter unless your exact model’s instructions expressly allow it. Remove loose dust using the prescribed dry method, and replace a damaged filter.
Check for damage as well as dust. Never operate the robot with a required filter missing, and do not reinstall a washed component while it is damp.
Are the Brushes Installed Correctly?
Turn the robot off and prepare it for underside inspection according to the manual. Remove hair from the main brush ends and check the side brush.
Reinstall bearings, end caps and the brush cover correctly. A loose cover or worn brush can affect pickup even when the motor sounds normal.

Should You Change the Settings?
After maintenance, try a stronger suction setting or another pass if offered. Test the same small area so the result is easy to compare.
If the robot avoids the area, review no-go zones, carpet handling and obstacles instead. Extra suction will not fix a blocked doorway or an excluded zone.
When Is Support the Next Step?
Contact iRobot support if the same fault remains after accessible parts are clear and correctly installed. Include the model, floor type, cleaning mode and any error message or unusual sound.
