If you are a cat owner, you know how much time and effort it takes to keep your cat’s litter box clean and fresh. The Litter-Robot 3 is an automatic litter box that aims to make this task easier and more efficient. This article will take a closer look at the Litter-Robot 3 and its features.

1.      Design

The Litter-Robot 3 has a unique, round design that sets it apart from other automatic litter boxes on the market. It measures 29.5 inches in height, 24.25 inches in width, and 27 inches in depth, making it a suitable size for most cats. The Litter-Robot 3 comes in several colors to fit your home décor.

2.      Automatic Self-Cleaning

One of the standout features of the Litter-Robot 3 is its automatic self-cleaning function. The litter box uses a patented sifting system that separates the clean litter from the clumps and waste, depositing them into a separate drawer. This means you do not have to scoop the litter box by hand, saving time and effort.

3.      Waste Drawer

The waste drawer is located at the base of the Litter-Robot 3 and is easily removable for cleaning. It is also lined with a garbage bag, making it easy to dispose of waste and preventing spills or messes. The waste drawer holds up to 4-5 days’ worth of waste for one cat and 2-3 days for two cats.

4.      Power Supply

The Litter-Robot 3 uses a standard 15V DC power supply, which is included with the unit. The power supply is also energy-efficient, using only about 5 watts of power during operation.

5.      Ease of Use

The Litter-Robot 3 is easy to set up and use. Fill the litter chamber with your preferred clumping litter, plug in the power supply, and turn the unit on. The Litter-Robot 3 will then cycle through a cleaning cycle after each use, leaving the litter box clean and fresh for your cat’s next use.

6.      Maintenance

The Litter-Robot 3 requires minimal maintenance, with most of the work done by the automatic self-cleaning function. But, it’s crucial to maintain a clean and clutter-free litter chamber and trash drawer to guarantee effective performance. Every few months, the litter chamber should be cleaned, and the waste drawer should be cleaned as needed.

Litter Robot 4

Cats are beloved pets, but dealing with litter boxes can be a major hassle. Fortunately, technology has come to the rescue through the Litter Robot 4. This innovative automatic litter box has revolutionized how cat owners manage their pets’ waste, making the process cleaner, easier, and more convenient.

An autonomous self-cleaning litter box called the Litter Robot 4 does away with the necessity for hand scooping. It’s a spherical-shaped device with a large opening that allows cats to enter and exit easily. The interior of the Litter Robot 4 is lined with a removable waste drawer and a special litter basin that sifts waste into the drawer automatically after each use.

How does it work?

After your cat has done using the litter box, the Litter Robot 4 can detect it using cutting-edge technology. Once your cat leaves, the Litter Robot 4 waits seven minutes before beginning a cleaning cycle. During the cleaning cycle, the litter basin rotates, causing the clumps to separate from the clean litter. The clumps then drop into the waste drawer below, leaving fresh, clean litter for your cat’s next use.

Difference between litter robots 3 and 4

The Litter-Robot is a popular automatic litter box that has gained a reputation for being reliable, convenient, and efficient. The company has released several models, including the Litter-Robot 3 and Litter-Robot 4. While both models share many features in common, there are also several key differences between them.

·         Design

Their design is the most noticeable difference between Litter-Robot 3 and Litter-Robot 4. The Litter-Robot 3 has a round shape and a slightly smaller size, while the Litter-Robot 4 has a more oval shape and is slightly larger. The Litter-Robot 4 also has a sleeker, more modern design that many users find aesthetically pleasing.

·         Capacity

Another key difference between the two models is their litter capacity. The Litter-Robot 4 has a larger litter chamber than the Litter-Robot 3, which means it can hold more litter and accommodate larger cats. The Litter-Robot 4 can hold up to 12 pounds of litter, while the Litter-Robot 3 can hold up to 9 pounds.

·         Odor Control

Litter-Robot 3 and Litter-Robot 4 have built-in odor control systems that help keep the litter box smelling fresh. However, the Litter-Robot 4 has an upgraded carbon filter that is more effective at trapping odors and preventing them from escaping.

·         Night Light

One new feature introduced with the Litter-Robot 4 is a night light. The night light illuminates the litter chamber, making it easier for cats to see and use the litter box in low-light conditions. Cats with eyesight issues or senior cats may find this extremely beneficial.

•        Connectability

You can monitor and manage the litter box using your smartphone by connecting the Litter-Robot 4 to the Litter-Robot app. You can get notifications when the trash drawer is full or the litter has to be replaced. The Litter-Robot 3 does not have access to this capability.

•        Pricing

The final factor to consider is the price difference between the two models. The Litter-Robot 4 costs more than the Litter-Robot 3 due to its upgraded and extra functionality.

Undoubtedly, the changes between the Litter-Robot 3 and Litter-Robot 4 are summarised in the table below:

How Much Can Waste Litter Robots 3 and 4 Hold?

When purchasing a self-cleaning litter box, capacity is one of the most crucial variables. Nobody likes to clear the trash or worry about an overflow regularly. In this article, we’ll compare the capacities of the Litter Robot 3 and 4 to help you decide which model is right for you.

Litter Robot 3 Capacity

The Litter Robot 3 has a waste drawer that holds up to 7 full-size cat waste deposits. This equates to roughly 12 cups of litter, which should last for several days for most cat owners. However, for those with multiple cats or larger breeds, the capacity of the Litter Robot 3 may not be enough to keep up with demand.

Litter Robot 4 Capacity

The Litter Robot 4 boasts a larger waste drawer than its predecessor, which can hold up to 12 full-size cat waste deposits. This translates to approximately 18 cups of litter, which can last up to a week for some cat owners. The increased capacity means less frequent emptying and a more convenient experience for you and your feline friend.

Factors Affecting Capacity

It’s important to note that the capacity of Litter Robots 3 and 4 can vary depending on several factors. The size and weight of your cat, the type of litter you use, and the frequency of cleaning cycles can all affect how quickly the waste drawer fills up. For example, if you have a larger cat breed, you may need to empty the waste drawer more frequently than someone with a smaller cat.

Additionally, some types of litter may create more waste or clump together more firmly, which can also impact the capacity of the waste drawer. A high-quality clumping litter is recommended for the best performance with either the Litter Robot 3 or 4.

Emptying the Waste Drawer

Regardless of which model you choose, emptying the waste drawer regularly is important to maintain optimal performance and reduce unpleasant odors. When the trash drawer is full and has to be emptied, a notification light on the Litter Robots 3 and 4 will let you know. If you have several cats or a heavy litter user, it’s advised to clear the waste drawer more frequently—at least once a week.


In conclusion, both the Litter-Robot 3 and Litter-Robot 4 are excellent automatic litter boxes that can save pet owners time and hassle. However, the Litter-Robot 4 offers significant upgrades over the Litter-Robot 3, including a larger capacity, improved odor control, and the ability to connect to the Litter-Robot app. If you have a larger cat or are looking for a litter box with advanced features, the Litter-Robot 4 may be your better choice. However, if you are on a budget or prefer a simpler design, the Litter-Robot 3 may be a better fit.
