Removing and Reinstalling Roomba's Brush Coupler
The Brush Coupler is a plastic piece with two metal bushings (see Figure below)
that holds the two Main Brushes in place on one side underneath Roomba. The
Brush Coupler needs periodic cleaning, which is usually is done when cleaning
the Main Brushes. However, if it looks like there is something wrong with the
Brush Coupler on your Roomba, please contact Customer Service for more
information.

If you need to replace the Brush Coupler, here's how to do it:
1. Simply follow the instructions for removing and cleaning the Main Brushes.
2. Once the Main Brushes have been removed, pull the Brush Coupler free
of the Brushes.
3. Clean off and examine the Brush Coupler (or replace a malfunctioning
Brush Coupler with a new one).
4. Follow the instructions for reinstalling the Main Brushes.
Cleaning the Vacuum Inlet
Over time, debris will accumulate in the Vacuum Inlet. Periodically remove the
Vacuum Inlet Lid and empty the Vacuum Inlet to keep air flowing through it,
especially if you notice a decline in the cleaning performance of Roomba. Here's
how to do it:
1. Turn Roomba's Main Power Switch to the Off position.
2. Place Roomba upside down (cleaning surface up) on a flat surface.
3. Insert a finger into the Release Tab and pull upward to remove the Lid (See
Figure).
4. Shake the debris into a trash receptacle.
5. Turn the Vacuum Impeller, the fan-shaped mechanism on the left side of the
Vacuum Inlet, with your finger to make sure that it spins freely.
6. Replace the Vacuum Inlet lid, pressing down on all four white circles on the lid
to ensure complete re-installation.
