THE MYSTERY OF LITTERMAID MODEL
A HIGHER MODEL NUMBER DOES NOT MEAN THAT IT IS A NEWER MODEL. The
latest LM500 is about 2 years newer than the LM800. The LitterMaid
model numbers can be very confusing and I believe this was done
intentionally. This is a marketing tactic known as product differentiation.
If you have ever purchased any type of major household appliance,
you have encountered this tactic. Have you ever wondered how so
many retailers can advertise that they have the lowest guaranteed
price for any given item? Even though the item may appear to be
the exact same one sold in another store, the model numbers will
be different. With the LitterMaid boxes, just remember that there
are two sizes, the standard and the Mega. The LM500, 520, 600, 600
Plus, 700, 750 and 800 are all the same size (about 16 inches wide
and 24 inches long). The LM900, 920 and 950 are the same width as
the others but they are 3 inches longer (about 27 inches without
the ramp) to accommodate large cats and those who need a larger
space. The LME5000 series and the LME9000 are the same width, but
again the 9000 is 3 inches longer. Many of the sellers will try
to convince you that the Mega (LM900 and LME9000 series) is for
multiple cats and the standard size is for single cat households.
I would like them to explain to me how this can be true when all
the LitterMaids operate the same way and they all have the same
motor. When a cat uses the box, he trips an infrared beam. Ten minutes
after he leaves the box, the motor will start and the rake will
move across the pan. Theoretically, if the box was not used more
than once every ten minutes, any LitterMaid machine would handle
an infinite number of cats. I know many people who use the standard
sized box for 4 cats, so don't be fooled by this attempt to get
you to purchase the large unit which will cost you a lot more. The
large size is for large cats and those who need the extra space,
that is it!
The different model numbers mainly have to do with
whichever retailer is selling the LitterMaid and what items are
included in the sale. The very early models had two large plastic
screws inside the litter pan. The labeling on top of the unit says
"LitterMaid" in black letters. The sides of the box are
smooth, with no latches. This is the LM-1 model.
The next model to come along was called the "Advanced"
or "Deluxe." Note the presence of side latches and the
writing on the box that says "Newer, quieter motor," which
still continues to be on the boxes as of today. I must say that
I have taken a lot of LitterMaids apart and all of them have the
same part number stamped on the motor no matter what the model number
is on the box including the new LME Elite units.
The same general design continued through several
model numbers including the 500, 600, 700, 750 and 800. The 500
and the 600 are the same thing except the 500 comes with four waste
containers while the 600 comes with twelve. There was a 600a that
included a Garfield food dish and a 600b that included a treatball.
The 700 and the 750 are the same as the 500 except they have the
word "plus" written on in red and different "bonus"
items were inserted inside the retail box including catnip toys
or carbon filters. The 800 is the same thing except it included
a ramp that attaches to the front. The LM900 or Mega uses the same
circuitry as the other models and is the same width. It is three
inches longer than the standard models Most of the parts are interchangeable,
however the motor/rake arm was slightly modified and is half inch
wider. The 900 is on the right in this photo.
All the models used to be a solid gray but then they
started adding "designer" colors. The smaller unit became
the 600 Plus and included maybe a ramp or a carpet depending on
who was selling them. After this, they started using the LM500 number
again. The 500V included a vacation certificate.
They also have some with blue pans and waste compartment
covers and the model number is 520 or 920. The 900 series has always
included a ramp but then they inserted a tent into the package and
sold this as the LM950. The 950 was only available on the LitterMaid
website however, some eBay sellers will put the tent together with
the LM900 and sell it as a 950. Also, some sellers have invented
their own model numbers by combining the LitterMaid units with other
The units were sold for a time in Europe. The model numbers were
LM100E and LM300E. While never having seen them, I would assume
that the 100E is the standard size unit and the 300E is the same
as the Mega except that these units came with an AC adapter that
would work in Europe.
As of this writing, the newest LitterMaid models are the LME (Elite)
series. The LME 5000 series is the smaller or standard size and
the LME9000 is the larger or Mega size. The LME9250 is the same
thing as the LME9000 except that the 9250 includes a "Kabana"
cover that fits onto the top of the unit. The LME5500 is the same
as the LME5000 except that the Kabana comes with the 5500. The LME
(or Elite) models are a complete re-design but the waste containers
and ramps will still fit on all models. The LMT100 tent will not
fit on the LME Elite units. The Elite series LitterMaids come with
a small ozone device to cut down on odor, a timer switch so that
you can shut it down at night if the noise bothers you and the rake
is now stainless steel instead of nylon. The rake is easier to remove
for cleaning. Personally, I would not use the timer if it is not
absolutely necessary. Cat deposits may build up and stick to the
pan which would cause strain on the gears inside the motor/rake
arm when the timer kicks in. The timer is also a clock so I guess
you or your cat can use this to check the time. Now you will have
one more clock to change when the power goes out and comes back
