How it Works:

7 minutes after your cat leaves the Litter Robot, the globe slowly rotates to allow clumps to fall into the plastic bag in the drawer below.  The globe then rotates back into original position.  Simply throw away the full plastic bag and replace it with a new one every few days.

Pros:

-Low operation costs.  If you think the Litter Robot is expensive, consider this: aside from the initial payment, no replacement cartridges or refills are required.  For certain other automatic litter boxes, the cost of refills for the first year alone is enough to buy a Litter Robot!

-Minimum effort required.  Just replace the plastic bag when it becomes full.  Tip: Do NOT wait until the bag is overflowing before replacing it.  An overflowing unit will result in speared poop on the outside of the globe when it rotates.

-The Litter Robot performs consistently well for the vast majority of people that are using it, and has earned a 4.5/5 stars on Amazon. Continue reading »

How it Works:

The Petsafe Simply Clean Automatic Litter Box constantly rotates (at one rotation per hour) to shift the litter around.  After the cat does its business, the clumps gets shifted continuously with the litter until they make contact with a conveyor that carries them to a hopper lined with a plastic bag (any plastic bag will do).  There are no moving parts (therefore sensors are not required to detect your cat’s movement) and the unit will continue to rotate while your cat does its business without the risk of getting its claws caught.  When the plastic bag gets full, simply take it out and replace it with a new one.

How it Works:

The ScoopFree litter box comes with a disposable tray already filled with litter crystals that absorbs urine and dries out poo after the cat uses it.  20 minutes after the cat leaves the litter, a rake automatically sweeps clumps into a covered trap to contain odor.  Periodically (up to every 30 days) you’ll need to throw away the disposable tray and slide in a new one.

Pros:

-A reliable and durable product that rarely gets jammed or otherwise malfunctions.

-Requires very minimal attention (just change the tray regularly). Continue reading »

How it Works:

Instead of the conventional litter, the CatGenie uses permanent washable granules that don’t require changing.  Cat pee drains through the granules into a reservoir of sani-solution below.  A scoop scoops up poo and deposits it into the hopper where it mixes with the sani-solution and gets liquified, then flushed down your toilet.  The CatGenie then uses fresh water to scrub the basin and granules clean.  The cycle finishes with a drying process where a hot air blower dries the granules.  You can start the flush manually or set the machine to flush automatically.

Pros:

-The Cat Genie is self-cleaning and self-flushing, and is the only automatic litter box on the market that currently does this. Continue reading »

How it Works:

10 minutes after the cat leaves the box, a rake would automatically move clumps into a sealable container beneath the box and then return to its original position.  An ionic air cleaner uses carbon filters to absorb odor to cut it down by 50%.  When the waste container is full, simply replace it with a new one.

Note: This product is ideal if you have a large cat or more than one cat. Continue reading »

How it Works:

10 minutes after your cat finishes its business and leaves the LitterMaid LM700 litter box, a rake automatically moves through the litter box to scoop the waste into a waste receptacle.  You’ll need to replenish the litter every so often, and also replace the waste receptacle as it fills up (the product comes with several waste receptacles to get you started, and more can be purchased separately from here).  The carbon filters that act to control odor will also need replacing and can be found here.

Pros:

-This litter box uses less litter than the traditional litter box.

-The LM700 is praised by many for its ability to effectively eliminate odor.

How it Works:

The LitterMaid LM900 has a sensor that senses when your cat leaves the litter box, and starts a 10 minute timer.  After the 10 minutes, the rake is activated to move the clumped waste to a plastic container, which needs to be replaced when it becomes full.  The litter box is also equipped with carbon filters that control odor.  You need to supply the litter yourself, as well as purchase replacements for the waste container (see here) and the carbon filters (see here).

Pros:

-The LitterMaid LM900 uses less litter than the normal (non-automatic) litter box.

-This litter box is quite effective in cutting down on odor.

How it Works:

15 minutes after your cat leaves the Smart Scoop litter box, the cleaning cycle begins where a rake moves the clumps and deposits them into a waste bin.  When the bin gets full, simply dispose of the waste bag and replace with a new one.  The litter box comes with a dozen waste bags and new refills can be purchased separately (from here).  The unit also comes with carbon filters that need to be replaced as well – you can find refills here.  Optionally, you can purchase the Smart Scoop No-Stick Litter Box Spray (available here) and the Smart Scoop Odor Control Litter Box Spray (available here).

Pros:

-The Smart Scoop litter box is relatively quiet in operation (when it’s not jammed or stalled).

-This litter box does a decent job in controlling odor.

How it Works:

After LitterMaid LME5500’s built-in sensor senses that your cat has left the litter box, it rakes the clumps into a waste receptacle.  You need to supply the litter yourself, as well as buy replacements waste containers (see here) and carbon filters (see here) after the initial supply (that comes with the unit) runs out.  The LME5500 also comes with a sleep timer that you can set to avoid getting woken up during the night.

Pros:

-The LitterMaid LME5500 is equipped with a rake that can be detached and cleaned easily (unlike for older models).

-It’s designed with a sleep timer to stop the unit from operating in the middle of the night.

-The carbon filters eliminates odors quite effectively.

10 minutes after the cat leaves the box, a rake would automatically move clumps into a sealable container beneath the box and then return to its original position.  An ionic air cleaner uses carbon filters to absorb odor to cut it down by 50%.  When the waste container is full, simply replace it with a new one (which you can find here).  You need to supply the litter, and the carbon filters will need replacing once in a while as well (you can find them here).  Note: This unit is designed for a large cat or multiple cats in the household.

Pros:

-The LME9000 model is equipped with a sleep timer which shuts off the machine while you’re sleeping.

-This model comes with a detachable metal rake (compared with the plastic non-detachable one from earlier models).
