The Brushes are not spinning properly, or there looks like there may be a
problem with the Brush Coupler.
The counter-rotating Main Cleaning Brushes should spin towards each other and
offer some resistance as they are spun by hand. If the Brushes spin too freely or
are very hard to spin, try the following steps:
1. Remove a nd clean the Brushes. Make sure there is not a lot of hair wound
around the ends (or Axles) of the Brushes. If there is, clean it off.
2. While the Brushes are out of Roomba, inspect and clean the Brush
Coupler. Are the two brass bushings still in place? If they are not, please
contact Customer Service.
3. Inspect the square sockets in Roomba that hold in the Brushes. Are they
still square or have they been rounded out? If they have been rounded
out, please contact Customer Service.
4. Reinstall the Brushes. Instructions can be found under Procedures.
Roomba is not sensing stairs properly.
Although Roomba senses stairs on the vast majority of floor surfaces, there is the
possibility that rounded edges, particularly slippery surfaces, or light colored
floors can contribute to the sensors working less effectively.
If Roomba is not sensing stairs, first empty the Particle Bin and then check for
any dirt or fuzz obstructing the Cliff Sensors (the four small pits located
underneath Roomba, just inside the edge of the Front Bumper). Alternatively, you
can use the Virtual Wall Unit to block stairs off.
Roomba won't run right out of the box.
Roomba will not run right out of the box, as its Battery Pack needs to be installed
and charged overnight before it will run. Also:
1. Ensure that the Battery Pack is properly seated and charged. See
Procedures (below) for detailed instructions.
2. Check all possible performance-related issues by checking the brushes
and ensuring the Debris bin is empty.
3. Roomba will not run if it isn't flat on the ground.
Roomba beeps in a flat tone when turned on.
You can only select a Room Size Button when Roomba is flat on the floor. Turn
off Roomba's Main Power Switch. Turn it on again and select a Room Size
Button, making sure that Roomba is flat on the floor.
