IMPORTANT SAFETY INSTRUCTIONS
READ AND FOLLOW ALL THE INSTRUCTIONS
CAUTION: Do not plug the power supply into a grounded outlet or do not switch
the pool cleaner “ON” if it is not fully immersed in water.
Operating the cleaner out of waterwill cause severe damage immediately and will
result in loss of warranty.
Allow the cleaner to remain in the pool for 15 to 20 minutes following the end of its
cleaning cycle. This will allow the motors to cool adequately. Do not leave the cleaner
in the pool all the time. Always remember to turn the power supply “OFF” and unplug
it from the power outlet before removing the cleaner from the pool.
WARNING: The cleaner must not be used when people are in the water.
For use with swimming pool only.
Safety Note
• The unit must be supplied through a residual current device (RCD or GFCI) having
a rated residual operating current not exceeding 30 mA
• The connection to the branch circuit should be consistent with the local and
national wiring rules (electrical code).
• Mishandling of the unit can result in leakage of lubricants.
• If the supply cord is damaged, it must be replaced by the manufacturer’s
service agent or a qualified and trained person in order to avoid hazards.

Mirra is designed to help keep your pool clean so that you can do more enjoyable things. However, there
are a few things we would like to explain in more detail so that you know your Mirra is working correctly.
1.) Mirra will spend a few moments calibrating the size and shape of your pool at the start of each
cleaning cycle. It will do this by making a few passes in a straight line and then turning and making
a few passes in the perpendicular direction. This will happen at the beginning of every cycle and will
take a few minutes.
2.) Mirra does not make perfect 90 degree turns. It will do its best to make a 90-degree turn but due to
its four-wheel base and the resistance of the water the turns are not perfect. Not to worry, over the full
cleaning cycle Mirra should turn enough to cover your entire pool for a thorough cleaning.
3.) Mirra turns by alternating its pump and drive motors. This behavior may cause the front wheels to lift
off of the pool floor periodically. This is normal.
4.) Mirra is programmed to spend more time cleaning the pool floor, where the majority of dirt, leaves
and other debris settle. Mirra will also clean the pool walls periodically, at predetermined intervals.
Therfore, Mirra will not always climb all the way to the water line when it hits the pool wall.
5.) After descending from a pool wall, Mirra may pause momentarily to recalibrate its gyro and position.
This will take a few seconds. This is normal.
6.) If Mirra does not seem to cover your entire pool, try starting a new cleaning cycle from the other end
of the pool.

Intake Valve Adjustment:
• The intake valves have a
plastic neck that can be
adjusted up and down.
• Try adjusting the intake neck
down to get better suction
for cleaning up fine debris off
the pool floor.
• Conversely, try adjusting
the intake neck up if Mirra is
getting stuck on your pool
floor filters. Adjusting the
intake neck up will give Mirra
better ground clearance.

Maintenance and Adjustment (Continued)
PVA Wheel Soaking:
• The PVA sponge wheels can
dry out and become hard
after long periods of storage.
• The PVA sponge wheels must
be wet and soft in order to
provide traction for driving
around the pool and up the
pool walls.
• Allow the robot to rest at the
bottom of the pool and let
the PVA sponge wheels soak
for at least 15 minutes before
starting a cleaning cycle. This
will ensure Mirra has optimal
traction and you get best
performance out of the robot.

Maintenance and Adjustment (Continued)
Float Blocks
• Mirra has a gyro that helps it navigate and turn in the pool.
• Mirra also uses a “Float to Turn” technique to make turns
which causes Mirra to do “wheelies” and drive on 2 wheels
when it turns. This is normal.
• Sometimes due to slippery pool surfaces or steep pool wall
slopes Mirra can still have hard times making turns. If this
behavior is noticed it is recommended to adjust the number
of float blocks inside the Mirra.
• The float blocks are located in a plastic holding rack inside
the body of the Mirra (seen in the picture to the right).
• To access the float blocks first remove the filter canisters.
Then find the float block holder located inside the body of
the robot and mounted on the side wall.

19 iRobot Mirra 500 Series Owner’s Manual
Maintenance and Adjustment (Continued)
Float Block Adjustment:
• Mirra comes with 2 float blocks already installed into the float block
holder (#1 & #2 seen in the picture). Mirra also comes with 2 additional
float blocks for manual adjustment (#3 & #4 seen in the picture).
• When the ideal number of float blocks are installed, Mirra should
perform a “Float and turn” maneuver and make approximately a 90°
turn. The 90° is soft and will occur in the shape of an arch but when
Mirra has finished its turning maneuver it should be traveling in a
perpendicular direction.
• If Mirra completes its turning maneuver and has turned less than 90°
then the robot is too heavy and not buoyant enough (Picture A1). This
is wrong. Add one float block and test the robot again (picture A2).
Continue to add float blocks (picture A3) until Mirra performs a soft
arching 90° turn (picture A4).
• If Mirra completes its turning maneuver and has turned more than 90°
then the robot is too light and too buoyant (picture B1). This is wrong.
Remove one float block and test the robot again (picture B2). Continue
to remove float blocks (picture B3) until Mirra performs a soft arching
90° turn (picture B4).

PLEASE CHECK THE FOLLOWING BEFORE CALLING YOUR SERVICE CENTER
Before troubleshooting, the pool cleaner must be disconnected from the power supply and the power supply must be unplugged from the electrical outlet to
prevent damage to the unit and possible personal injury.
1. Unit does not pump water or move:
a) Check to see if electric outlet has power.
b) Check if transformer is plugged into a grounded outlet and the cable
assembly is plugged into the transformer.*
c) Switch the power supply “OFF” and “ON” a few times.
Allow 45 seconds between “ON” and “OFF”.
d) Check for and remove any debris such as hair, string, or leaves that may
be obstructing the free movement of the wheels.
2. Unit does not pump water at all, or pumps slowly but moves:
a) Check to see if propeller is seized due to accumulation of hair or debris
on the propellers. Remove the top screw on the outlet top and clean the
propeller. When reassembling the top cover, do not overtighten the screw.
b) Check to see if the filter canisters are thoroughly clean. Clean as necessary.
c) After following all of the above, if there is still a problem,
visit global.irobot.com or call 1-800-845-4856 or (973) 857-2700.
3. Unit does not move but does pump water:
a) Check to see if forward/reverse motion is obstructed by foreign
matter; hair, debris, etc. on wheels or there is an entanglement
with the power cord.
b) Check there is no debris stuck inside the wheel between gears
c) Verify if the rolling brush is properly positioned and not broken.
The brush is transferring the rotation to the wheels and - if broken- the robot
will not move properly.
d) After following all of the above, if there is still a problem,
visit global.irobot.com or call 1-800-845-4856 or (973) 857-2700.
4. Unit does not climb the wall:
a) Check to see if the filter canisters are thoroughly clean. Clean as necessary.
5. Unit does not pick up dirt and debris:
a) Check 2a and 2b of this guide.
b) Extend the water intake (see page 16)
c) Check the Filter Intake Valve Flaps on the underside of your unit
(see image below). The Flaps should move freely to open and close.
Clean and free the Valve Flaps if necessary.
6. Unit does not seem to cover the entire pool:
a) Most likely a thorough cleaning of the filter is needed.
b) Verify that the unit rotates by 90 degrees on the first turn of a new cycle.
If not - add or remove floats according to the instructions on page 18 & 19.
c) Check to see that the floating cable is properly spread out and is untangled.
d) Allow the unit to run in the pool for the entire cleaning cycle.
e) Check that the Motor is operating.
f) After following all of the above, if there is still a problem,
visit global.irobot.com or call 1-800-845-4856 or (973) 857-2700.
7. Debris Comes Out Of The Unit When Removing It From Pool
a) Filter lock handle (Top Access Lid Does Not Close Properly) -
Check that the Lock handle release mechanism is not damaged.
The lid edges should be aligned with the unit’s body and the top
filter is properly locked.
b) Intake Valves - Check that the Filter Intake Valve Flaps (see image above)
move freely to open and close. Clean flaps if necessary.
