Why Litter-Robot 4 is one of TIME’s Best Inventions of 2022


Wondering what’s so futuristic about this invention? How about a robot that takes care of the litter box for you! Litter-Robot 4’s automatic sifting process quietly separates kitty’s waste from the clean litter, leaving a fresh bed of litter every time. Pet parents spend zero time scooping litter and a lot less time worrying about whether the litter box is clean enough for kitty.

We were so nervous that our cat wouldn't use it, but he learned fairly quickly. We call it his spaceship and he's a starship captain. This tool has brought us into the future and changed our lives! – Kelly

Just a brilliant invention. No more scooping out the waste; no more dirty litter for my cats to use. I'm in love. Thank you so much. – Jill

Smarter pet care

As TIME states, Litter-Robot 4 can be “controlled through [the Whisker] app, allowing pet owners to monitor waste and litter levels, and get alerts when litter needs to be replaced.” Not only can pet parents track litter and waste drawer levels in real time, they can monitor kitty’s litter box activity and weight. 

I enjoy using the app to see the weights of my cats, how often they are using it, and when I need to empty the tray. Worth every penny! – Dru

Litter-Robot 4 is quiet and the app tracks our cats’ weight and frequency, it tells me when the litter needs refilled or the drawer needs to be emptied. I will never go back to scooping again. – Sean

Superior odor control

Litter-Robot 4’s ability to neutralize odors is a selling point for pet parents and TIME. Because waste is promptly cycled into Litter-Robot 4’s tightly sealed waste drawer, pesky litter box odors are largely contained. The large waste drawer contains a carbon filter, which can be swapped with OdorTrap™ Packs to further eliminate odors.

OMG!! Definitely a life changing experience. I have a small apartment so having a litter box can be smelly. Litter-Robot 4 blocks the smells and it saves me more time throughout the week not having to scoop poop from the box. – Jenni

I am so happy I bought this litter box. It is whisper quiet, like I don't hear a thing. It also reduces odor. When you walk into the house, no one believes I have a cat because you don't smell anything!! 10/10 will recommend!! – Kitten

Multi-cat friendly

Having multiple cats no longer equates to needing multiple litter boxes. As reported by TIME, one Litter-Robot 4 is perfectly suited for up to four cats. The consistently clean bed of litter is great for even the most territorial felines.

Not having to scoop has been a game-changer and our cats love having fresh litter every time they go. The wide opening is so inviting and it took no time getting used to. If you're a multi-cat household like us you NEED a Litter-Robot! – Joy & T.

Litter-Robot 4 has made such a difference in our household! Multi-cat home and ability not to scoop anymore! So quiet while self-cleaning. Love that the robot can monitor the weight of our cats. – Lilyandlunz
