PETKIT vs. Litter-Robot vs. PetSafe Self-Cleaning Cat Litter Boxes

Everyone knows that cats are awesome, but if you’re tired of dealing with smelly litter, we’ve got some wonderful news for you. You can rely on a self-cleaning litter box to do your (or your pet cat’s) bidding!

Below, we’re going to compare three of the most top-rated cat litter boxes available today.

PETKIT Pura X

The PETKIT Pura X is a neat little device that works by using a rotating inner drum and slotted scooping fence to separate cat droppings from litter. Any solid waste captured by the scooper fence is dropped into the 5-liter capture tray underneath that, by user reports, can store several weeks’ worth of droppings for single-cat owners.

Built into the Pura X are four different sensors, known as the xSecure system, that are there to ensure your pet’s safety every time. All of the sensors will stop the rotating action whenever they detect moving objects nearby or inside. xSecure consists of infrared, thermal, and thermal sensors.

But since poop falls into a collection tray, doesn’t that mean the smell will permeate the air in your kitchen? Not at all! The Pura X has a built-in odor removal spray that sprays a fine mist of liquid that neutralizes foul odors and formaldehyde. Based on user reports, the Pura X is virtually odor-free, even when standing right next to it.

The Pura X is designed for cats under 18 pounds and to ease the life of cat owners everywhere. Syncing the device to your smartphone via the PETKIT app will allow you to receive status reports at any time of the day.

Users can also activate automatic cleaning and receive notifications if there’s a problem with the device. Basically, you’ll always be in the loop regarding your cat’s poop, even when you’re not there scooping it up.

Litter-Robot 3 Connect

The Litter-Robot 3 Connect is a fancy device that automatically cycles after your pet cat drops its business. Users can set how long the 3 Connect will begin its cycling function to 3, 5, or 15 minutes after your cat has left the robot. This feature lets you decide whether you want to get rid of the smell as soon as possible or wait a little bit until the droppings clump properly.

The 3 Connect works similarly to the PETKIT Pura X. Whenever your cat has done its business, the internal drum will make one full rotation and sift out the used litter from fresh litter. The clumps are dropped into a waiting bag while fresh liter is left at the base and ready for more of your cat’s poo.

When the collection bag is full, the device will stop what it’s doing and alert users via the Whisker app that they need to replace the bag.

This device uses two different types of sensors that detect motion and weight. Even while the 3 Connect is in the middle of a cycle, it’ll stop what it’s doing and allow your cat to safely conduct its important business before resuming after the selected waiting time. What users will find is a reduction in litter wastage and the convenience of never having to scoop out poop ever again.

One super-thoughtful feature of the 3 Connect is its blue nightlight for older cats. At nighttime, the gentle glow will let your cat know where to go to drop a steamer. In sleep mode, the device will postpone its scooping cycle for up to eight hours.

PetSafe ScoopFree Self Cleaning Cat Litter Box

Last up, we have the simplest self-cleaning cat litter box of them all—the PetSafe ScoopFree. This tool doesn’t use fancy rotating drums; instead, it comes with a simple metal rake that pushes cat poop and used litter to a disposal collection tray hidden underneath the litter tray. The disposable collection tray is good for up to 30 days.

What’s pretty neat about the ScoopFree is how it tracks how many times your cat comes to the box based on how many times the rake does its thing. There’s also a manual rake button on the control panel, so if on the off-chance the ScoopFree fails to work, a simple press of a button will handle the smelly mess for you.

While it may look like a simple device, the ScoopFree actually comes with some incredibly sensitive sensors that know when your cat’s doing its business and when it has existed the litter box. The sensor will stop the rake from what it’s doing if your cat has an emergency in the middle of the raking cycle.
