Automatic Litter Robot for Cats: Pros and Cons

For feline lovers, home does not feel like home if it lacks an adorable cat. Reduced maintenance costs, relaxation from the need for formal training, and frequent grooming make them the perfect pets. However, one can't deny that no matter how precious and important cats might be, it is unbearable to stand the unpleasant smell of their waste. Despite their quiet, independent, and hygienic nature, cats, like any other pet, are unable to scoop their litter boxes, assigning this awful responsibility to their owners. Well, technology has discovered the solution to deal with this least amiable task of owning a cat – A “Litter Robot,” that would serve as a robot litter box and will automatically scoop your cat’s waste out of the cat litter; providing the neat litter bed every time your cat visits it.

So, if you are a choosy cat lover, tired of manual scooping of your cat’s waste, this blog will help you save from the hectic job of maintaining a traditional cat litter box as you will get a chance to learn a lot about Litter Robots. Whether you go on a weekend trip or have an unpredictable schedule, a Litter-Robot will relieve you from the stress of cleaning your cat's waste, as the gadget will automatically do it.

What is a Litter Robot? How does it Work?

A Litter Robot is an automatic litter box manufactured by a US-based company named “Whisker” (previously known as AutoPets) – a leading trendsetter in pet technology and accessories. This Litter-Robot helps you avoid frequent manual scooping of cat litter while maintaining a neat and clean litter bed for it. This spaceship-resembled robotic cat toilet is Wi-Fi enabled to connect to your smartphone or smartwatch and sends notifications to keep you informed about every activity happening inside. You will get this robot litter box in completely assembled form. So, no extra effort is required to connect any separate part. Just remove it from the box and plug it in; it is ready to work.

10 Best Robot Dogs: Pros and Cons
Robot dogs are taking the world by storm, but is having one a good idea? If you’re so excited to buy them but confused about choosing, you’ll be thrilled by this blog. We’ve provided information on how much they cost and what makes them special. Let’s take a closer look at our 10 best robot dogs.

The main parts of a cat Litter Robot include:

  • Globe: The barrel-shaped part of the Litter Robot has the litter tray for the cat. The sifting process starts in this compartment.
  • Bonnet: The part wrapped around the globe. It is required to complete the electric circuit. The globe will not rotate without it.
  • Base: this is the powerhouse of the Litter Robot, having a motor, control panel, and wiring inside.
  • Waste Drawer: the drawer in the base where all the clumped waste is deposited.

For proper functioning, a Litter-Robot also has inbuilt sensors and carbon filters.

Once your cat enters this robotic toilet and does its business, it does not start the cleaning process promptly but waits until your cat steps out of it. The inbuilt sensors of the Litter Robot record the cat's weight and check the weight difference inside the box to avoid any cat injury. Once it senses that the cat has stepped out of the robot, its timer starts for the dirty litter to get clumped with the cat's waste. You can set this "wait time" based on your preference; however, Whisker suggests seven minutes. After this time, its self-cleaning process starts automatically inside the globe. The globe is just like a cement mixer but filled with cat litter. It is the place where the cat discharges its waste on the litter inside. It rotates and compels the litter to pass through a carbon filter that segregates the cat’s waste from the litter, and the carbon filters also reduce the waste smell. After this sifting process, the wet litter with absorbed poop or pee converts into messy clay. The globe deposits this clumped waste into the waste drawer inside the base. Once the cat's waste is scooped out in the waste drawer below, the globe starts rotating in the opposite direction and places the cleaned litter back in its position for the next visit.

Once the poop drawer is full of waste, the Wi-Fi-enabled cat Litter Robot sends you a notification on your device to get it emptied. Just pull it out and remove the waste. To keep the poop drawer clean, line it with a litter or garbage bag. Just open the drawer, remove the garbage bag, and line the drawer back with a new and clean bag. If you have one cat, the drawer must be voided once a week.

If you are concerned that the cat’s waste, being placed in the drawer for several days until it is full, may cause an unpleasant smell in your home, just relax! The poop drawer of the Litter-Robot is enclosed from all sides. Moreover, it is equipped with an air filter to keep odor under control. However, the only time you may smell litter is while clearing the drawer.

Important Note: If the weight of your kitten is less than 5 pounds (in case of Litter Robot 3) or less than 3 pounds (in case of Litter-Robot 4), deactivate the automatic sifter as it might be difficult for the robot to sense a cat with this little weight and may start the cleaning process while the kitten is inside. However, if you have a young kitten with a lower weight, switch the mode from "Auto" to "Manual." Observe when your cat has discharged its waste and left the Litter Robot; turn it on to start the cleaning process, and turn it off manually once you get the “Cleaning Process Done” notification on your mobile.

Emotional AI: How Robots Show Emotions?
The potential of AI systems to generate emotional connections is critical in making robots more human-like — even if only on a basic level — because it allows them to comprehend not just actions but also the thoughts and feelings that go along with them (which requires having some form of memory).

Whisker App: The Litter Robot has a QR code at its back. Synch to the Whisker app using the QR code and download this app on your mobile or smartwatch. This app delivers comprehensive data about the number of times your cats are discharging waste. It seems ridiculous to get this information, but this data might be helpful for your veterinarian if your cat suffers from some health issues. It also notifies when the robot litter box completes the cleaning process and when the waste drawer is full to its capacity with the clumped waste. You can monitor the use of the automatic litter box from your phone and even name your Litter-Robot using this app.

Which is the Best Litter for Litter Robot?

A Litter Robot does not require any special litter. However, Whisker recommends natural, unscented, and low-tracking litter. “Clay-based Clumping Litter” of premium quality is considered the best for a cat Litter Robot; however following types of litter don't work for it:

  • Non-clumping litter
  • Loose-clumping litter
  • Permeable wood pallet litter
  • Paper-based litter

Can You Use “Pretty Litter” in Litter-Robot?

Pretty Litter” is the litter made of high-grade, finest silica gel crystals that feel as if it is sand. The silica gel crystals and beads can also be used as litter for a litter robot if they are fine enough to filter through the screen. User experiences reveal that "Pretty Litter" was not working well for a traditional litter box; however, for a Litter-Robot, it works better. The litter robot reviews further reveal that the cats attract more to the pretty litter and their paws track less of it outside the Litter Robot than the clumping clay litter. However, the only drawback of pretty litter they claim, is you can't monitor your cat's health as you won't be able to observe the color change in the "Pretty Litter."

Important Things to Consider while Handling a Litter Robot

  • Avoid pushing this Litter Robot against the walls.
  • Avoid overfilling the globe with litter. Otherwise, it may fall in the waste drawer during cleaning cycles. Whisker recommends filling the globe just up to its fill line; approximately 8-10 pounds of cat litter is recommended for the globe.
  • Never use bleach when cleaning the litter robot, as it can degrade the plastic.

How to Clean the Litter Robot?

When it comes to cleaning a Litter Robot, a little attention is required as it is more flexible and easier than cleaning a traditional litter box. You neither need to scoop daily (or ever) nor replace the litter frequently. Each part of the system was designed to ensure easy upkeep. Regarding the detailed cleaning of the litter robot, you can go for it every 1-3 months, based on your cat's behavior and your preference. It's better to perform some basic cleaning once a month. Whisker offers you aroma-free and pet-friendly cleaners to sanitize the globe particularly. This cleaner, available in both forms – Spray and Wipes, contains natural and safe ingredients that include:

  • Water
  • Amino acid enzymes
  • Good Bacteria

Clean the globe with wipes or direct spraying on it; be careful to spray or wipe the wires or any electronic component.

Robotics in Childcare: Benefits and Drawbacks
Robotics is a rapidly evolving technology that can be used for a variety of purposes, including space exploration and entertainment. Robotics in childcare recognize when children enter the nursery and greet them, as well as can monitor their heart rate, sleep, movements, and body temperature.

How to Deep Clean the Litter Robot?

The manufacturer “Whisker” recommends to deep clean your Litter Robot about 3 times a year. Let's have a look at the step-by-step guide for deep cleaning:

  • Deposit all the litter from the globe into the waste drawer by pressing the “Empty” button. Wet litter converts into messy clay, and its pieces might get stuck to the walls that are hard to remove. If you notice any leftover litter in the globe, brush it out thoroughly.
  • Press the ON/OFF button to switch off the Litter Robot and unplug it.
  • Now it’s time to disassemble the litter robot and start deep cleaning.
  • Remove and clean the bonnet: For this, press and release the snap tabs on both sides of the bonnet, then lift and tilt the bonnet towards the back, remove it and set it aside. Now clean it with a wet rag and mild soap. Avoid washing it with water as it has some electric components inside.
  • Remove the globe: Grab the globe in both hands, and lift it off the base.
  • Disinfect the globe using Whisker's cleaner (spray/wipes): You can also wash it with water and some gentle soap as it does not have any electronic component inside. If you feel the globe is awfully dirty, you can soak and clean it with the water hose.
  • Dry off the globe thoroughly. Use a dry towel or air dry it if required.
  • Clean the waste drawer: Open it up and untie the garbage bag in which all the clumped waste of the cat is accumulated. Remove and throw it away. Now, pull out the drawer from the base, clean it with soap and water, and dry it off with a rag. Take a new trash bag (8 to 13 gallons capacity) and tie it off inside the waste drawer.
  • Clean the base: Wipe out the outer surface of the base with a wet rag and soap. Never let the base get wet from inside as it has electronic parts, and the water can damage them. Never submerge it in water.
  • After deep cleaning all the components, it’s time to reassemble the Litter Robot.
  • Attach the globe to the base and the bonnet to the globe. Place the waste drawer back inside the base. That’s all!
