Litter-Robot III Open Air Review

In a market packed to the brim with cheap gimcracks, being called the best automatic litter box is no mean feat. The Litter Robot III Open Air has managed to gain that moniker and hold onto it for quite some time now.

A closer look reveals that it’s not without reason, either. Completely redesigned from the ground up, the Litter-Robot III brings flawless automation to the table and takes the guesswork out of a task that is often on the list of ‘least desirable chores’ around the house.

If you were on the fence about buying this automatic litter box due to the not-so-pleasing price tag, then here’s our Litter-Robot III Open Air Review that shows how it is completely worth every dollar you’ll spend on it.

Futuristic Appeal

To say that it looks like a Martian space probe would be an understatement. The Litter-Robot III’s capsule design is a looker and will grab eyeballs no matter where you place it in your home.

This allows you to allocate it prime real estate in your living room, rather than hiding it away in your bathroom.

It is reasonably compact at 26.8 x 24.4 x 29.1 inches and can fit snugly in a corner without seeming out of place.

Even the largest feline can easily enter the litter chamber thanks to a large and wide entryway. The litter chamber itself is quite roomy and ideal for cats weighing 5 lbs. or more. It also allows larger cats to turn around, which is a huge advantage compared to cramped boxes the cats often refuse to use.

For this reason, cats take a liking to the Litter-Robot III almost instantly.

Spotless Cleaning

The Litter-Robot III outperforms any other automatic litter box on the market with its amazing automation. It has a hooded design that gives your privacy-loving cat its own dedicated poop chamber and prevents the dreaded ‘poo splatter’ on the walls.

A built-in weight sensor detects the weight of the cat and automatically adjusts the cleaning cycle accordingly. This ensures that irrespective of the weight of the droppings, they are collected and dropped into the waste compartment. There will be no left-behind clumps that can stink.

Also, there is no rake that collects the droppings. The clumps just drop down into the waste compartment, which translates into less time cleaning any feces-covered rakes.

The odor control is excellent. The waste is absorbed instantly and there is no lingering smell even inside the litter compartment. If you have more than one pet, you can also choose to manually cycle the Litter-Robot III after every use.

One of the best features is that a blue indicator light starts to blink once the waste compartment is full. This prevents leaks and clogs and takes the guesswork out of cleaning.

Easy to use

The Litter Robot III may look like a space pod, but it is ridiculously easy to use. That’s what makes this a winner. The control panel is intuitively placed and there are minimal buttons to tinker with. Most of the settings, like adjusting the cycle time, are accessible in one to two clicks, making usage a breeze.

You can choose to adjust the cycle delay time by 3, 7, or 15 minutes, depending on how fast or slow your pet is. Aging cats often take time to get done with their pooping and then there are the perpetual diggers who seem to dig for hours. Completely customizable!

The buttons are labeled well and even if you are an elderly pet parent, you can read and access them with ease.

You can dump the waste by just clicking a button, which is as hands-off as it gets. There are no plumbing or waste lines to hook up with the machine. It comes almost ready-to-use.

There’s also a lip extender and a rubber mat that prevents your kitty from tracking litter all around the house.
