“Futuristic”: TIME’s Best Inventions of 2022

TIME annually awards innovative products and impactful ideas to their list of Best Inventions—and Litter-Robot 4 is included in TIME’s Best Inventions of 2022! TIME describes Litter-Robot 4 as a “futuristic self-cleaning cat litter box” and further highlights that it can be controlled through the app, “allowing pet owners to monitor waste and litter levels, and get alerts when litter needs to be replaced.” 

The selection also notes that Litter-Robot 4 neutralizes odors and can be used for up to four cats. We’re honored to see Litter-Robot 4 on such a prestigious list of inventions!

“Best overall”: Good Housekeeping Institute

Since 1900, Good Housekeeping has employed a team of engineers, scientists, analysts, and product experts to rigorously test the products you care about. The team recently designated Litter-Robot 4 as the “best overall self-cleaning litter box” that “makes daily scooping obsolete.” 

In the Good Housekeeping Litter-Robot 4 review, the reviewer writes, “Primarily what you get with the Litter-Robot 4 is your time back—plus a much more sanitary way of dealing with cat waste. The very hands-on chore of scooping the litter box becomes a thing of the past, and monitoring when you need to change litter goes on autopilot, thanks to the app.”

Good Housekeeping also answers the question that’s top of mind for many pet parents: “Yes, it’s worth the high price tag.”

“Stellar odor control”: WIRED

WIRED is an essential source of information and ideas that make sense of a world in constant transformation, offering the latest in technology, science, culture, and business. The WIRED Litter-Robot 4 review rates the product 9/10, nicely summarizing its benefits: “Anti-pinch safety features. Nearly silent. Stellar odor control. Roomy drum and large waste drawer. Useful app tracks weight and bathroom habits. No scooping!”   

The reviewer calls the Whisker app “excellent” and touts Litter-Robot 4’s odor control: “It’s impressive how well it contains the stench.” The product’s modern design was also humorously worth noting: “Considering that it’s essentially a vessel for clumps of poop and pee, I don’t hate looking at it in my living room.”

“Perfect for multi-cat households”: HGTV

HGTV editors research, test, and review products to develop curated picks. In the HGTV Litter-Robot 4 review, the reviewer describes her switch to Litter-Robot 4: “I can’t see a world where I will ever go back to a regular litter box.”

Litter-Robot 4 is highlighted as “the perfect option for households with multiple cats,” noting that “you can no longer rely on your nose to let you know when it's time to remove the waste—and that’s saying a lot!”

The reviewer is also a fan of Litter-Robot’s self-cleaning capabilities, saying “I love being able to go out of town and only have to ask friends to feed [my cat] rather than scoop his litter box (and my friends love that too!).”

“Splurge-worthy staple”: House Beautiful

House Beautiful is dedicated to bringing you the best in inspiration and education for your home. Founded in 1896, it’s the oldest continually-published design magazine in the U.S. In the House Beautiful Litter-Robot 4 review, the reviewer declared the product “a splurge-worthy staple cat lovers will obsess over.” 

The reviewer raves, “The [Litter-Robot 4] design is sleek and easy to tuck into a corner where it won't draw attention—I've had house guests ask where the litter box is after staying with us for several days and they are shocked to find out they've been five feet away from it the whole time.”

Litter-Robot 4 is also included in House Beautiful’s 2022 Live Better Awards. 

“Brilliantly designed”: CNN Underscored

CNN Underscored is a trusted source for hands-on product testing, honest reviews, and guides covering deals, tech, beauty, style, home, personal finance, travel, gifting and more. In the CNN Litter-Robot 4 review titled “Never scoop poop again with the sleek, brilliantly designed Litter-Robot 4,” the publication touted Whisker as the one brand that consistently rises to the top of the self-cleaning litter box game. 

As a resident of a small New York City apartment, the reviewer praised that Litter-Robot 4 fit perfectly into the space they had used for their previous traditional litter box. “Litter-Robot 4 is a dream for those who may have unpredictable schedules, or those who frequently leave their cats home for a couple days at a time,” she said. “The peace of mind alone might be worth the investment.” She also noted that the “airtight odor-control of the waste drawer is a game changer for those who have to put their litter box in an open space (like a living room).”

To sum up: “Everything Whisker says Litter-Robot 4 can do, it does brilliantly.”

“As a helicopter cat mom,” she concluded, “let me be the first to say that [Litter-Robot 4] is so worth it for both your quality of life and your pet’s.”

“Game-changer for cat parents”: Daily Beast

The Daily Beast delivers award-winning original reporting, fact-informed analysis, and sharp opinions, with their Scouted team specializing in “Internet shopping with a pulse.” The Daily Beast Litter-Robot 4 review called the product “actually attractive” and “a game-changer for cat parents.”

As a cat parent of five, the reviewer had used past Litter-Robot models. She said Litter-Robot 4 is “the perfect option” for transitioning your cat/cats to an automatic, self-cleaning litter box, particularly due to the quiet cleaning cycle. She praised its upgrades and features for better performance and “an even better look,” including a built-in smart scale to help you keep track of your kitty’s weight and activity.

The reviewer placed emphasis on the benefits for multi-cat homes: “If you have more than one feline at home, this home upgrade will literally change your life. Yes, it’s pricey but worth every penny.” 

“Unexpected and welcomed upgrade”: Daily Paws

Daily Paws provides pet parents with expert information and make-you-smile pet news. As a “happy owner” of previous Litter-Robot models, the Daily Paws Litter-Robot 4 reviewer wasn’t sure what improvements the new and improved Litter-Robot had in store—or if the improvements were worth the price tag.

“We've always loved that the unit cycles way sooner than I would scoop,” she said, “keeping the litter fresher longer and, in turn, keeping our cats healthier.”

Happily, Litter-Robot 4 passed the test. “The added bonus of weight monitoring is an unexpected and welcomed upgrade,” said the reviewer. “Being a pet parent to a cat with a bad knee, we're glad to ditch our weekly weigh-ins and Google Doc weight tracking.”

She also mentioned that, along with the other updates, “Litter-Robot 4 is sleeker while actually widening the globe size for bigger kitties.”

“Extremely worth the price”: Woman’s Day

Woman’s Day is a destination for celebrations big and small, where readers are VIP guests treated to fresh new ideas guaranteed to help them discover the yay in every day. The Woman’s Day Litter-Robot 4 review said the product is easy to set up, simple to use, and “has worked extremely well to eliminate litter box odors” in the reviewer’s one-bedroom apartment. 

With two cats and two different personalities at home, the reviewer was pleased that both kitties started using Litter-Robot 4 right away. She also saw how effective the SafeCat system is when her cat put his paws on the ledge to peek inside: “His weight was detected right away and cycling stopped.”

Conclusion: “Eliminating the chore of scooping altogether feels extremely worth the price.”

“Keeps your home fresh”: Design Milk

Design Milk is built on the foundation of sharing, supporting, and fostering global creativity in design, art, architecture, technology, and beyond. The Design Milk Litter-Robot 4 review highlighted keeping “your home fresh and your to-do list short.”

Said the reviewer, “While I’ve heard plenty about self-cleaning litter boxes, I’ve been hesitant to introduce one to my cats as they can be, well, finicky about new things.” Happily, Litter-Robot 4 proved that there’s “a lot packed into its compact body: advanced litter-sifting technology, real-time monitoring, health insights, odor neutralization, and more.”

“Rolls-Royce of litter boxes”: Futurism
