Cleaning the

Main Brushes

It is important that you regularly remove and clean the Main Cleaning Brushes of your Roomba. Debris can accumulate around the Brushes and the Brush ends, or axles, causing a decrease in cleaning ability and poten- tially damaging the unit. If the Main Brushes are not

Reassembling the Brushes

1.Put the Self-Adjusting Cleaning Deck back together by inserting the square ends of the two Brushes into the square sockets in the Cleaning Deck.

2.Insert the other ends of the Brushes into the small holes in the Brush Coupler.

3.Lower the Brush Coupler into its slot and screw it into place.

4.Swing the Wire Guards back in place and snap them down into their slots in front of the Release Tabs.

cleaned regularly your Roomba may seriously mal- function.

In most households it’s a good idea to clean the Main Cleaning Brushes after every ten floor cleanings. In houses with pets or long hair, clean the Brushes after every five floor cleanings. The Main Cleaning Brush axles cannot be checked without removing the Brushes from Roomba. It is a simple process that you will master quickly with a little practice.

1.	If Roomba’s power is on, turn it off. Empty the
	Particle Bin and place Roomba upside down
	(cleaning surface up) on a flat, padded surface
	such as a towel, with the Front Bumper facing
	away from you.
2.	Unlatch the Wire Guards that cover the Main
	Cleaning Brushes from the two Release Tabs
	(Figure 22): Push down on the Wire Guards to
	flatten and elongate them, and pull the front edge
	of the Wire Guard (the edge nearest you) toward
	you to swing it up and over both Release Tabs to
	expose Brushes. (see Figure 23a-b).
3.	Using a Phillips-head screwdriver, completely
	loosen the screw in the Brush Coupler, the compo-
	nent that holds the Brushes in place on the right
	side of the unit (Figure 23c). Note that the screw
	will not come all the way out of the Brush Coupler
	so you cannot lose it. Pull up the Brush Coupler
	(see inset in Figure 23d.) The Main Cleaning
	Brushes will come up with the Brush Coupler.
4.	Pull the Brush Coupler off the end of the Brushes,

Figure 23a-b: Unlatch the Wire Guards from the two Release Tabs by pushing down on the Wire Guards to flatten and elongate them, and pulling the front edge of the Wire Guard toward you to swing it up and over each Release Tab. Once the Wire Guards have been freed from the Release Tabs, they can be swung up and away, exposing the Main Cleaning Brushes.

Figure 23c-d: Completely loosen the screw on the Self-Adjusting Cleaning Deck with a #2 Phillips screwdriver, then pull out the plastic Brush Coupler and the two Main Cleaning Brushes. If there is a thumbscrew on the Brush Coupler, you may be able to loosen the screw by turning the thumb- screw with your fingers.

Cleaning the Vacuum Inlet

Over time, debris will accumulate in the Vacuum Inlet. Empty the Vacuum Inlet every 10 floor cleanings or so to keep air flowing freely, especially if you notice a decline in Roomba’s cleaning performance.

1.If Roomba is on, turn it off and empty the Particle Bin.

2.Place Roomba upside down (cleaning surface up) on a flat, padded surface with the front Bumper facing away from you.

3.Press in the white rectangular Release Tab on the Vacuum Inlet Lid to release the latch (Figure 25a), and pull upward to remove the Lid.

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 (Figure 25b).

6.Guide the hinge tabs on the Vacuum Inlet Lid back into their holes (Figure 25c), and press in and down on the white rectangular Release Tab to snap the Lid securely back in place.

5.	Clean any hair or other debris off the Brushes.
6.	Completely clean any debris from around the
