Setting Up Your Litter-Robot
1. Place the Litter-Robot in the same location as the
old litter box, if possible.
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. 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 (“OK/Waiting” on the Control Panel).

At this point, the Litter-Robot is ready to be filled
with litter.
Note
Please 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 leave the Litter-Robot’s
power cord unplugged 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 for the best
results of getting your cat acclimated:
•Place the Litter-Robot in the same location as the
current litter pan. Set up the Litter-Robot according
to the instructions and unplug it from the wall after
the initialization cycle has been completed. Give
your cats a day or so 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.
•After your cats are at ease with the Litter-Robot you
can fill the Litter-Robot with litter. Fill the Litter-
Robot with clean litter according to the instructions
(see next section of this manual), and then add a
scoop of litter from the old litter pan. This provides
a familiar smell to the cat.
•Once you notice that your cat has used the Litter-
Robot, you can cycle the unit manually by simply
plugging in the unit’s power cord. 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.
Unplug the power cord 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.

•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 entice 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 plug in the power cord and let the
unit operate in the unattended 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!

Installing Garbage Bags in the Waste
Drawer
Your Litter-Robot is shipped with a 13 gallon trash bag
already installed in the waste drawer - two extra trash
bags have been provided. The standard 13 gallon bags
were chosen for their size, availability, and low cost.
Standard 8 gallon trash bags also work well.
To install a 13 gallon trash bag in the waste drawer,
open the bag and slide the rim of the bag behind the
four mounting clips in the drawer. Make sure that the
opening of the bag is taut and that it covers the entire
perimeter between the four mounting clips.

Filling the Litter-Robot with Litter
The Litter-Robot litter sifting system requires a clumping
type litter to work properly. Clumping clay litter is
recommended. This type of litter will have the words
“clumping” or “scoopable” on the bag or container. The
Litter-Robot is also compatible with World’s Best Cat
Litter, Litter Pearls, and crystals. Litters that do not
work in the Litter-Robot are the strictly absorbent clay-
based, non-clumping litters, newspaper based litters and
Feline Pine. 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.
To fill the Litter-Robot with litter, follow these steps:
1. Make sure the Litter-Robot power cord is plugged in
and that the Globe is in the home position.
2. Litter can be added to the Globe in two ways:
•Filling through the entrance opening (Step 3)
•Filling through the square waste ports (Step 4)

3. Filling through the entrance opening
Make sure that the Globe is in the home position.
Scoop approximately 9 lbs or 1½ gallons of litter
(whichever is less) in the Globe.
With the Globe in the home position, the litter level
should not be higher than about 2 inches below the
bottom rim of the cat entrance opening.
After adding litter to the Litter-Robot you can start
a cleaning cycle by pressing the “Cycle” button on
the Control Panel. Any excess litter will be dumped
into the waste drawer. At the end of the cycle the
litter bed will be leveled.
Do not add litter through the round holes
located on the bottom of the Globe.

4. 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). With
the Internal Guard in this position the waste ports
are open.
Next, press the "Fill" button on the Control Panel.
This starts the Globe’s rotation, bringing the waste
ports to the top - a position convenient for filling.

14
Pour approximately 9 lbs or 1½ gallons of litter
(whichever is less) through the square waste ports
in the Globe, If you over-fill, the excess litter will
be expelled during the first few cleaning cycles.
Do not add litter through the round holes
located on the bottom of the Globe.
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 about 2
inches below the bottom rim of the cat entrance
opening.
5. If this is the first time you filled the Litter-Robot and
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 will
cling to all interior surfaces of the Globe. Clinging litter
will eventually be released, but not necessarily at an
ideal moment causing some granules to bounce out
through the waste ports or the entrance opening during
the clean cycle. The static cling should subside within a
few cycles.

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.
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. The maximum litter level is about
2 inches below the lower rim of the entry opening.
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 with 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.

18
To adjust the sensitivity of the Cat Sensor, see the
next section: “Adjusting the Cat Sensor Sensitivity”.
4. Next, with the green light on (“OK/Waiting”), take a
2 liter soft drink bottle, filled with water, and place it
on its side on the step. (If you do not have a 2 liter
bottle available, you can use a few large cans of
soup or other items from the kitchen pantry –
combined weight should be around 5 lbs). As an
alternative, you can press down on the step with
your hand and then release (see figures below).
The 5 lbs weight should activate the Cat Sensor, as
indicated by the red light (“Sensor/Timing”). The
applied force represents your smallest cat stepping
on the drawer. If the effort required to trip the Cat
Sensor is considerable, the sensor is not sensitive
enough and needs to be adjusted. Skip Step 5 and
go to the next section that explains how to make
these adjustments.

5. 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
1. Make sure that the Globe contains the desired
amount of litter before adjusting the sensor
sensitivity. The maximum litter level is about 2”
below the lower rim of the cat entry opening.
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).

4. TO DECREASE THE SENSOR
SENSITIVITY
To decrease the sensor sensitivity, lift
the front of the Base unit and rotate
the Rotatable Foot to the right (about
¼ turn at a time – see figure). You
may hear a clicking noise as you
rotate the foot – this is normal.
5. TO INCREASE THE SENSOR
SENSITIVITY
To increase the sensor sensitivity, lift
the front of the Base unit and rotate
the Rotatable Foot to the left (about
¼ turn at a time – see figure). You
may hear a clicking noise as you
rotate the foot – this is normal.
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 ¼ to ½
turns before the desired sensitivity is achieved.

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.
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.

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 retracts for approximately
2 seconds.
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. Unplug the power cord
2. Remove the obstruction
3. Reposition the Globe in the home position
4. Plug the power cord back in. 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.

Cleaning & Maintenance
The Litter-Robot requires no special maintenance. We
recommend that you do not lubricate the four Teflon
glide buttons on the Base unit. Lubricating these glide
buttons will allow 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.

26
Press the "Empty" to move the waste ports to the
discharge position. The Litter-Robot Globe rotates
clockwise to dump the litter into the waste drawer.
Press any button to stop the rotation if you want to
interrupt the Empty cycle. 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 routine cleaning, a damp soapy rag is
probably sufficient and will allow the Globe to dry
quickly.
For a quick touchup, you can use a disposable wipe
(such as Lysol or Clorox) to wipe the inside of the 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 instant.
Cleaning the Waste Drawer
The drawer can easily be removed and cleaned with
soap and water.

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’s power cord
unplugged 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.

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 30 days of purchase for a
refund of the purchase price (less shipping). 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?
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 with a variety of litter alternatives
including litter beads and pearls. Litters that do not
work in the Litter-Robot are the strictly absorbent clay-
based, non-clumping litters, newspaper based litters and
Feline Pine.
How much litter do I put in the Litter-Robot?
Start with no more than 9 lbs of litter. Make sure that
the distance between the litter bed and the bottom rim
of the cat entry opening is at least 2 inches. 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, the Feline Pine pellets are too large to pass through
the sifting screen. This prevents the litter sifting system
from working properly.
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.
What are the dimensions of the Litter-Robot?
•The fully assembled Litter Robot is 27 ½” high, 21
½” wide and 24” deep.
•The waste drawer is 10 ½” wide, 13” long and 4”
deep.
•The oval shaped entry for the cat is 8 ¾” high and 6
½” wide.
•The litter bed area measures 14” across at
maximum litter capacity.
•There is 13” to 15” of head room for the cat inside
the Globe depending on the level of litter. The
inside width is 20” across at the widest point, and
depth is 15” front to back.

Troubleshooting
1. All lights on the Control Panel are blinking once per
second.
If the Globe cannot find the home position, all three
lights on the Control Panel will blink at a rate of
once per second. Make sure the Litter-Robot is on a
level surface. If the condition persists, please
contact Customer Service.
2. Yellow light on the Control Panel is on.
The Yellow light comes on when a cycle is
interrupted by the Cat Sensor. The Litter-Robot will
wait 2 minutes before resuming the cycle. If the Cat
Sensor is continuously interrupted for more than two
minutes the Litter-Robot will stop and the Red light
will start flashing.
3. Red light (“Sensor/Timing”) on the Control Panel is
flashing.
This condition indicates that the Cat Sensor was
triggered for more than two minutes.
a. Check to see that the Litter-Robot is on a
level surface.
b. Make sure that there is no excess litter in
the Globe. The litter level should be at least
two inches below the bottom rim of the cat
entry opening.

d. Unplug the unit’s power cord and remove
the drawer and Globe. Locate the Anti-
pinch safety line in the Base and check to
see if it is too tight (see figure below). If
the safety line appears taut (there should be
some slack in the line), contact Customer
Service.
3. Lights on the Control Panel are blinking twice per
second.
If the Globe becomes jammed or if the rotation of
the Globe has become obstructed, the motor will
stop and all three lights on the Control Panel will
blink at a rate of twice per second. Follow these
steps to reset the unit:
•Unplug the power cord
•Remove the obstruction
•Reposition the Globe in the home position
