iRobot Roomba Robotic FloorVac - Manual (Page 10)

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.
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.

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
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,
then pull the Brushes to the right and up, out of
Roomba (Figure 23d).
5. Clean any hair or other debris off the Brushes.
6. Completely clean any debris from around the
Brush Axles (Figure 2
4
).
Figure 24: Clean and
remove any debris
built up or wound
around the ends and
metal axles of both
Cleaning 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.
