Troubleshooting Tips
My Roomba turns on, beeps and shuts off.
Roomba’s Main Cleaning Brush axles may be clogged with hair or other debris.
1. Make sure Roomba is fully charged and the Battery is properly seated.
2. If Roomba is charged, then empty the Particle Bin (see Emptying the Particle Bin on page 16) and follow the instruc-
tions for removing and cleaning the Main Brushes (see Cleaning the Main Brushes on page 18). Pay special attention to
the Brush ends, or axles.
My Roomba is not working or there has been a decrease in the cleaning performance.
1. Ensure that the Battery is properly seated and charged.
2. Check that the Particle Bin (including the Filter Chamber) and Vacuum Inlet are empty, and that the Vacuum Impeller,
(the fan-shaped mechanism on the left side of the Vacuum Inlet) spins freely. (See the entire section entitled Caring for
Your Roomba Pro, beginning on page 16 for more information.)
3. While you are examining the Filter Chamber, check the Air Filter (attached to the Filter Door) to make sure it is not
clogged or damaged.
4. Remove and examine all Brushes and their axles to make sure there is nothing wound around them (see Cleaning the
Main Brushes on page 18 as well as Maintaining the Edge-Cleaning Side Brush on page 20). Also check to see there is
nothing wound around the Wheels or Wheel Axles.
My Roomba Gets Stuck.
Your Roomba may occasionally get stuck, especially in rooms that it has not cleaned before. If it does get stuck, Roomba
will try to free itself by turning in different directions. If it cannot free itself, Roomba will pause its cleaning cycle, flash its
Room Size Buttons and beep periodically for five minutes to let you know it’s stuck, before shutting off to conserve power.
Your Roomba might get stuck for several reasons:
1. It is wedged or pinned between or under narrowly spaced objects.
2. A cord, string, long rug fringe or carpet tassel is wound around its Brushes or Wheels.
3. One of the Wheels is no longer in contact with the ground.
4. Roomba bumps into objects and repositions them in such a way that an exit path no longer exists.
Move or block any object that Roomba gets stuck on or under. See the illustration entitled “Roomba Care Hints” on the
back cover of the Quick Start Guide to help identify and easily fix these problem areas. Once the problem areas have been
fixed, press the flashing Cleaning Cycle Button to continue Roomba’s cleaning cycle. If you wish to begin a new cleaning
cycle, press Roomba’s Power Button to turn it off, then turn it on again. Make sure the Particle Bin is empty and select the
desired Cleaning Cycle Button to start a new cleaning cycle
My Roomba Remote doesn’t work.
1. Make sure the Roomba Remote has new batteries.
2. Make sure that Roomba is operational by turning it on and off with the Main Power Button on Roomba. If Roomba
won’t turn on, check that Roomba’s Battery is charged and completely installed.
2. Check that Roomba’s Beam Receiver (see Figure 3A) is clean by wiping it with a soft, dry cloth. Clean the Roomba
Remote’s transmitter area (on the front end of the Remote) by wiping it with a soft, dry cloth.
3. Make sure you are close enough to Roomba for the Remote to work. Try pointing the Roomba Remote at your Roomba
from less than 20 feet away, press the Power Button on the Roomba Remote and wait to hear Roomba’s Start-Up beep .
Ensure you are pointing the correct end at Roomba.
Maintaining the
Edge-Cleaning Side Brush
Periodically check the Edge-Cleaning Side Brush by
spinning it to ensure debris has not built up underneath it.
If it seems to be obstructed, remove and clean the Edge-
Cleaning Side Brush as follows:
1. If Roomba is on, turn it off and empty the Particle
Bin. Turn Roomba over so the cleaning surface is up.
Place it on a flat, padded surface.
2. Turn the Edge-Cleaning Side Brush so the Screw Head
can be accessed (see Figure 26). Point the screw head
towards Roomba’s Front Bumper, as shown below.
3. Using a small Phillips-head screwdriver, unscrew the
holding screw.
4. Pull the Edge-Cleaning Side Brush up and off of
Roomba.
5. Clean out any hair or other debris that may have
been caught under the Side Brush or on the Side
Brush Shaft.
6. Push the Side Brush back onto the Side Brush Shaft.
Screw the holding screw securely into the Edge-
Cleaning Side Brush, being careful not to over-tighten.
Keeping Roomba’s
Sensors Clean
Occasionally, lint or other debris will collect in Roomba’s
key sensor areas, which may cause Roomba to exhibit
unexpected movement behavior. If this happens, clean
these areas as follows:
1. If Roomba is on, turn it off and empty the Particle
Bin. Turn Roomba over so the cleaning surface is up.
Place it on a flat, padded surface.
2. Using a cotton swab, check and clean out any lint or
other debris from the four recessed sensor areas
located under the Front Bumper (Figure 27).
