Important – Read This First
The Litter-Robot™ has been designed to be used as
a self cleaning litter box for cats between 5 and 15
lbs. It is not intended for any other use.
The Litter-Robot is not recommended for kittens, or
small cats that weigh 5 lbs or less.
Always be sure that each cat in your household is
heavy enough to activate the Cat Sensor before you

Setting Up Your Litter-Robot
1. Place the Litter-Robot in the same location as the
old litter box, if possible. Make sure the Litter-
Robot is placed on a level, firm surface.
2. Put the Globe on the Base with the Cat Entry
opening facing the front as shown in the picture
below. Make sure that the track on the Globe
engages with the gear in the Base unit
.
3. Plug the small connector from the AC adapter into
the socket in the back of the Base unit. Next, plug
the main power cord into a wall outlet. Press the
ON/OFF Switch - the Litter-Robot will perform an
initialization cycle (this takes about 3 minutes).
After completing the cycle, the Globe should be in
the “home” position with the green light on.

4. Now fill the Globe with litter. The Litter-Robot litter
sifting system requires a clumping type litter to
work properly. The Litter-Robot is also compatible
with corn based
World’s Best Cat Litter . Litter
beads, and crystals can also be used with the Litter
Robot as long as the beads and crystals are small
enough to pass through the screen – periodic
changing of this type of litter is required. Litters
that DO NOT work in the Litter-Robot are the
strictly absorbent, non-clumping litters, newspaper
based litters, and Feline Pine Absorbent Pellets. If
you are using a litter alternative not listed here, you
can contact us at [email protected] to make
sure you are using a compatible litter.
If you are filling the Litter-Robot for the first time
we recommend that you do not switch litter brands
at this time. Your cats need to get used to this new
litter box and introducing a new kind of litter may
increase their level of apprehension. However, if
you are currently using a non-clumping litter you
will need to switch to a clumping style litter.
Litter can be added to the Globe in two ways:
Filling through the entry/exit opening (A)
Filling through the square waste ports (B)
A. Filling through the entry/exit opening
To facilitate filling the globe through the entry/exit
opening, disengage the globe from the gear and
simply rotate the globe back and away from you

Toll Free: 877-250-7729 www.Litter-Robot.com

such that the opening is in a more upward
orientation making it easier to pour or scoop litter
into the Globe.
For the initial charge of litter we recommend
starting with 9 to 10 lbs. of standard clumping litter
or approximately 1 ½ gallons of volume, whichever
is less.
With the Globe set back in the home position and
the litter spread evenly, the level should not be
higher than the ‘Fill Line’ ring (see figure below).
After adding litter to the Litter-Robot you can start
a cleaning cycle by pressing the “Cycle” button on
the Control Panel or by turning the unit OFF then
ON with the switch on the back of the Base. If you
accidentally over-fill the globe, excess litter will be
expelled into the waste drawer. At the end of the
cycle, the litter bed will be leveled.

B. Filling through the waste ports (square holes)
First, make sure that the Globe is in the home
position. Look through the Cat Entry opening and
locate the ribbed handle of the Internal Guard
inside the Globe, on the right. Grab this handle and
rotate it upward (clockwise) until it snaps into a
horizontal and locked position (see figure). Note
that the pin on the opposite side of the globe
should be locked behind the spring as shown below.
Next, make sure the Green light is on. Note that if
the Green light is not on, turn the unit OFF then ON
again and wait for the initialization cycle to
complete - you can leave Guard in its locked
position. If the Red light is on you can simply press
any of the three buttons to reset the unit and the
Green light should then be illuminated. Now press
the ‘Fill’ button. This starts the Globe’s rotation,
bringing the waste ports to the top - a position
convenient for filling.

Now pour 9 to 10 lbs. or 1½ gallons of litter
(whichever is less) through the square waste ports
in the Globe. If you over-fill the Globe, the excess
litter will be expelled into the Drawer during the
first few cleaning cycles.
Note that you may want to use a towel to cover the
cat entry/exit opening when filling through the
waste ports as it will help reduce dust kicked up
during the filling process.
After pouring litter in the Globe through the waste
ports, pressing any button on the Control Panel will
return the Globe to the home position.
Next, grab the handle of the Internal Guard and
rotate it downward (counter-clockwise). This closes
the Internal Guard. The square waste ports are
now covered by the Internal Guard.
When the Globe is in the home position, the litter
bed should be level and not higher than the fill line.
If you over-fill the Globe, the excess litter will be
expelled into the Drawer during the first few clean
cycles.
Tip
If this is the first time you have filled the Litter-
Robot and you are trying to get your cats
acclimated, you can pour a cup of used litter from
the old litter box on top of the new litter in the
Litter-Robot. This will provide a familiar scent for
your cat. See the section “Getting Your Cat to Use
the Litter-Robot” for more tips.

Note
During the first few days of operation the plastic
Globe may exhibit a high degree of static charge.
Litter may cling to all interior surfaces of the Globe.
Clinging litter will eventually be released, but this
may take several clean cycles.
Please also keep in mind that the Cat Re-entry
Protection is active during the initialization. If your
cat is eager to check out her new litter box, you
may want to prevent her from stepping on the
drawer during this phase to allow the initialization
cycle to be completed without interruption.
To ensure that your cats ease into this new litter
box experience, you can turn the Litter-Robot OFF
for a few days to give your cats sufficient time to
get accustomed to the Litter-Robot.
The next section contains some proven ideas to get
your cats to use their new self-cleaning litter box.

Getting Your Cat to Use the Litter-Robot
Most likely, your cat will quickly adapt to the Litter-
Robot. We recommend the following steps:
Place the Litter-Robot in the same location as the
current litter pan. Set up the Litter-Robot according
to the instructions (make sure you add litter to the
Globe) and make sure it is turned OFF. Give your
cats a day or two to explore the Litter-Robot. If
your cats show no interest, you can entice them to
approach the Litter-Robot by using some catnip or
their favorite treat.
Add a scoop of litter from the old litter pan. This
provides a familiar scent to the cat.
Once you notice that your cats have used the Litter-
Robot, you can cycle the unit manually by turning
the unit ON. If the cats are present, it will give
them a chance to observe the motion and become
familiar with the sound of the Litter-Robot while you
are present to reassure them. Turn the unit OFF
again after the cleaning cycle has completed (the
Litter-Robot should be in the home position). We
recommend that you no longer clean the old litter
pan once the Litter-Robot has been used by your
cats.
Toll Free: 877-250-7729 www.Litter-Robot.com
14
If your cats are not using the Litter-Robot within a
few days, continue using the old brand of litter in
the old litter box, and let it go as long as possible
without cleaning it. Cats prefer a clean litter box
and a dirty litter pan might persuade them to use
the clean Litter-Robot. You can also consider
replacing the litter in the Litter-Robot with a kind of
litter specifically formulated for litter box training.
Once your cats are consistently using the Litter-
Robot, you can turn the unit ON and leave it ON
letting it operate in automatic mode. You can now
remove the old litter box.
Congratulations, you have successfully introduced your
cats to the Litter-Robot. Enjoy your freedom from litter
box scooping!

How the Cat Sensor Works
The Litter-Robot Cat Sensor is a weight sensitive switch
that detects your cat entering or exiting the Globe.
Your cat must be at least five (5) lbs for the
sensor to work. Do not use the Litter-Robot with
kittens or cats that weigh less than five lbs.
Always be sure that each cat in your household is
heavy enough to activate the Cat Sensor before
you let the Litter-Robot operate in automatic
mode.
Make sure the Litter-Robot is placed on a level
firm surface. Placing the Litter-Robot on deep
carpet may require adjusting the cat sensor
(more sensitive).
A seven minute count-down is started when the cat
leaves the Globe. At the end of the count-down the
Litter-Robot will start its cleaning cycle. Any subsequent
tripping of the Cat Sensor starts a new seven minute
count-down, preventing the Globe from rotating with
your cat inside.
Caution:
Please make sure that your smallest cat weighs at
least 5 lbs before operating the Litter-Robot in
the unattended automatic mode. Your cat must
weigh at least 5 lbs to trip the Cat Sensor.

Testing the Cat Sensor
1. First, ensure that the Litter-Robot contains the right
amount of litter. Please refer to Fill Line on page 5.
2. Make sure that the green light on the Litter-Robot
Control Panel is on (“OK/Waiting”).
3. If the red light is on (“Sensor/Timing”), push any of
the buttons (Cycle, Fill, or Empty). This resets the
unit and the green light should come on
(“OK/Waiting”). Next, proceed to Step 4 of this
Testing procedure.
If the red light stays on (“Sensor/Timing”), the Cat
Sensor is too sensitive and needs to be adjusted.
To adjust the sensitivity of the Cat Sensor, see the
next section: “Adjusting the Cat Sensor Sensitivity”.

Toll Free: 877-250-7729 www.Litter-Robot.com
25
4. With the green light on (“OK/Waiting”), gently press
down on the step with your hand until you sense a
slight displacement or tilt, then release (see figures
below). The red light should come on. The applied
force represents your cat stepping on the Drawer. If
the effort required to trip the Cat Sensor is
considerable, or you have noticed the sensor is not
activating when your cat enters the Litter-Robot,
then the cat sensor is not sensitive enough and
needs to be adjusted. Skip Step 5 and go to the
section that explains how to make these
adjustments.
5. Now push any of the three buttons on the Control
Panel to reset the unit. If the green light comes
back on (“OK/Waiting”), the Cat Sensor is working
properly and you have successfully completed the
Sensor Test.
If the red light is still on (“Sensor/Timing”), the Cat
Sensor is too sensitive and needs to be adjusted.
The following section shows how to do this.

Adjusting the Cat Sensor Sensitivity
Note: The cat sensor is set at the factory for
optimal performance for most cats. Adjustment
should not normally be necessary.
1. Make sure that the Globe contains the desired
amount of litter before adjusting the sensor
sensitivity. The maximum litter level should not
substantially exceed the Fill Line in the liner.
2. Remove the Globe for easier access to the Cat
Sensor Switch. It may also help to remove the
waste drawer from the Base unit.
3. Slightly lift the Base unit and locate the Rotatable
Foot at the front and center of the Base (see figure).
More Sensitive – Turn Left
Less Sensitive – Turn Right

27
4. TO DECREASE THE SENSOR SENSITIVITY
To decrease the sensor sensitivity, lift the front of
the Base unit and turn the Rotatable Foot to the
right (about 2 full turns at a time – see figure).
5. TO INCREASE THE SENSOR SENSITIVITY
To increase the sensor sensitivity, lift the front of
the Base unit and turn the Rotatable Foot to the left
(about 2 full turns at a time – see figure).
Toll Free: 877-250-7729 www.Litter-Robot.com
28
6. Next, if it was removed earlier, slide the waste
drawer back into the Base unit and place the Globe
back on top of the Base. Now, test the function of
the Cat Sensor again.
If the red light stays on after attempting to reset the
unit, the Cat Sensor is too sensitive.
If red light does not come on when your cat enters
the Globe, the Cat Sensor is not sensitive enough.
7. The Cat Sensor may have to be re-adjusted several
times by rotating the Foot in increments of 1 to 2
full turns before the desired sensitivity is achieved.
Note: The cat sensor is set at the factory for
optimal performance for most cats. Adjustment
should not normally be necessary.
Make sure the Litter-Robot is placed on a level
firm surface. Placing the Litter-Robot on deep
carpet may require adjusting the cat sensor
(more sensitive).

Safety Features
Cat Re-Entry Protection Mode
If the Cat Sensor detects that your cat is trying to enter
the Litter-Robot during a cleaning cycle the Globe will
stop rotating. The Litter-Robot then waits for 15
seconds before attempting to resume the clean cycle.
Anti-Pinch Safety Feature
The Litter-Robot comes equipped with an anti-pinch
feature to make the Litter-Robot extra safe for your cat.
If a potential pinch condition is detected, the Globe
automatically stops and then reverses direction for
approximately 2 seconds.

Toll Free: 877-250-7729 www.Litter-Robot.com
30
Internal Guard
The Litter-Robot Globe has an Internal Guard that
covers the waste ports. The purpose of the Internal
Guard is to prevent cats from entering the Globe
through the waste ports. It also prevents litter from
getting kicked out.
During the cleaning cycle, just before the Globe reaches
the “dump” position, a mechanism moves the Internal
Guard out of the way to open the waste ports. When
the Litter-Robot Globe starts rotating back to the home
position, the Internal Guard automatically closes,
covering the waste ports again.
Automatic Shut-Off
If the Globe becomes jammed, the motor will stop and
all three lights on the Control Panel will start blinking at
a rate of twice per second. To reset the unit, follow
these steps:
1. Turn off unit and unplug the power cord
2. Remove the obstruction
3. Reposition the Globe in the home position
4. Plug the power cord back in and turn on. The Litter-
Robot will perform an initialization cycle. Please
keep in mind that the Cat Re-entry Protection is
active during the initialization.
If this condition persists, please call Customer Service,
toll-free, at 1-877-250-7729.

31
Cleaning and Maintenance
The Litter-Robot requires no special maintenance. We
recommend that you do not lubricate the four plastic
‘glide buttons’ on the Base unit. Lubricating these glide
buttons will cause dirt to build up.
Before you clean the Litter-Robot please make sure that
you remove all litter from the Globe - wet litter turns
into messy clay.
Emptying the Litter-Robot
Look through the Cat Entry opening and locate the
ribbed handle of the Internal Guard on the right, inside
the Globe. Rotate this handle upward (clockwise) to
lock the Internal Guard in the “open” position (see
figure). The Internal Guard is locked when the handle
snaps into a horizontal position. The waste ports on the
right side of the Globe are now open. Note that the pin
on the opposite side of the globe should be locked
behind the spring as shown below.

Press the "Empty" button to rotate the globe to the
discharge position, with the waste ports directed into the
drawer. After the litter has dumped into the waste
drawer, you can press any button on the Control Panel
to return the Globe to the home position.
If some litter remains in the Globe, you may want to
sweep the remainder out with a brush.
Cleaning the Globe
After removing all litter from the Globe, clean the Globe
with water and a mild soap. There are no electronic
components in the Globe which can be damaged by
soap and water. If the Globe has become extremely
dirty, it can be soaked or cleaned with a water hose. Be
sure that the Globe is completely dry before returning it
to the Base.
For a quick touchup, you can use a disposable towelette
to wipe the inside and upper half of the Globe. This can
be done without removing the litter. The Litter-Robot
can be used immediately after this touch-up because
drying is almost instantaneous.
Cleaning the Waste Drawer
The drawer can easily be removed and cleaned with
soap and water.
Cleaning the Base
Never submerge or soak the Base. The Base
contains the Cat Sensor and electronics. You can wipe
the surfaces of the Base with a cloth dampened with a
disinfectant.

Carbon Filter
The Litter-Robot comes equipped with a flexible carbon
filter pad for absorbing odors in the drawer. The carbon
filter can be easily removed and replaced when cleaning
the drawer. The carbon filter is not required and
replacement frequency is based on personal preference,
however one filter should last a few months under
normal use. Replacement filter kits (3 filters in a kit) can
be ordered from customer service at 1-877-250-7729 or

Frequently Asked Questions
Will my cat actually go inside the Globe?
Cats are generally curious and will investigate any new
object. Cats that are already used to a covered litter
box may be quicker to investigate. We recommend that
the Litter-Robot be placed in the same location where
the old litter box used to be. The old litter box can be
left near the Litter-Robot for a short time. Take a cup of
litter from the old litter box and add it to the clean litter
in the Litter-Robot. The scent will be familiar, and the
cat will be inclined to investigate. Once your cat has
ventured inside and feels the litter under its paws, it will
know what to do. Please read the section “Getting Your
Cat to Use Litter-Robot” in this manual.
Can kittens use the Litter-Robot?
We do not recommend that kittens or cats weighing 5
lbs or less use the Litter-Robot in the unattended
automatic mode. Their low weight may not activate the
Cat Sensor. Cats should be at least 5 lbs before using
the Litter-Robot in the automatic mode.
CAUTION: Leave the Litter-Robot turned off and
only start the cleaning cycle manually (see
“Getting Your Cat to use the Litter-Robot”) until
you are sure that all cats in the household are
heavy enough to activate the Cat Sensor.

Toll Free: 877-250-7729 www.Litter-Robot.com
37
What if my cat won't use the Litter-Robot?
If you and your cat are not completely satisfied, just
return your Litter-Robot within 90 days of purchase for a
full refund of the purchase price. Please note that you
are responsible for return shipping costs. Please contact
Customer Service to request a Return Authorization
(RMA) number. Return shipments without an RMA
number cannot be accepted.
What happens if my cat tries to enter the Globe
while it is rotating?
The Cat Sensor will detect the presence of your cat and
turn off the motor. The Litter-Robot pauses 15 seconds
before resuming the clean cycle.
Are there any rakes, or wires inside the Globe?
No, the Globe does not contain any rakes or wires that
could hurt or harm your cat. The Litter-Robot was
designed with your cat’s safety in mind.
Are the electronics or power source dangerous to
my cat?
No, the Litter-Robot operates on a safe 12 Volts using
an adapter very similar to the ones you may have at
home for a clock radio, or for charging your cell phone.
All electrical components are located in the Base, away
from where the cat could reach them. There are no
electrical components inside the Globe.

Will the Globe turn while my cat is inside?
No, the Globe will not turn while your cat is inside. The
Cat Sensor is tripped each time a cat enters, or re-enters
the Globe, resetting the count-down timer to prevent the
cleaning cycle from starting for another seven minutes.
What happens if the Globe jams?
If the Globe jams or an excessive load condition occurs
the motor is turned off automatically. In addition, the
Litter-Robot is equipped with an anti-pinch safety
device.
Does the Litter-Robot require special litter?
No, the Litter-Robot does not require special litter. In
fact, the Litter-Robot works just fine with any clumping
type litter and some biodegradable litter alternatives
such as World’s Best Cat Litter. Some litter beads and
crystals can also be used with the Litter Robot. Litters
that do not work in the Litter-Robot are the strictly
absorbent, non-clumping litters, newspaper based litters
and Feline Pine.
How much litter do I put in the Litter-Robot?
Start with approximately 9 to 10 lbs. of litter. Check
that the litter does not exceed the Fill Line, however if
there is too much litter in the globe it will be expelled
into the drawer during the first few clean cycles . Since
the waste clumps are removed during every cycle, there
is no need to put excessive litter in the Globe.

Does the Litter-Robot work with Feline Pine?
No, Feline Pine pellets are too large to pass through the
sifting screen. This prevents the litter sifting system
from working properly. Feline Pine clumping is also too
fluffy to effectively pass through the sifting screen.
How often do I need to add litter?
Experience shows that with two small cats (approx. 8
lbs. each), litter needs to be added about once a week,
and sometimes it will last longer than that. The Litter-
Robot uses litter very efficiently since the patented
sifting mechanism only removes the clumps.
Is dust a problem with the frequent rotation of
the Globe and the movement of the litter?
No, any dust is negligible since the Globe rotates very
slowly.
How often do I need to empty the drawer?
This depends on the number and size of your cats. For
two average-sized cats, twice per week is typical. For a
single cat, once per week is usually sufficient.
How often do I have to clean the inside of the
Litter-Robot Globe?
This depends on your personal preference and your cat’s
behavior. However, we recommend that you clean the
inside of the Globe every one to three months.

How do I clean the Litter-Robot exterior?
Cleaning the Litter-Robot exterior is easy. Just remove
the Globe and the Drawer and give them a sponge bath,
or take them outside for deep cleaning with the garden
hose. All other surfaces can be wiped clean but should
not be submerged.
CAUTION: The Base of the Litter-Robot contains
electrical components and is not meant to be
submerged or wet. See the “Cleaning the Litter-
Robot” section for more details.
