# šŸ” How does the Litter-Robot 4 reduce odors? *Published: 2024-04-16 | Updated: 2024-10-12 | Source: https://shopsavvy.com/answers/how-does-the-litter-robot-4-reduce-odors* --- ## Product: Litter-Robot 4 **Brand:** Whisker The Litter-Robot 4 is a neat choice for anyone with multiple cats looking to cut down on litter box odors. It's a self-cleaning litter box that handles up to four cats' waste effectively, just as the manufacturer describes. The way it tackles odors is pretty smart. After your cat leaves the litter box, the Litter-Robot 4 automatically sifts through the litter to separate the waste from the clean stuff. This quick action helps stop odors from hanging around your place, which is a big plus if you've got a full house of cats. Our research shows that a lot of folks mentioned this feature keeps their homes smelling fresh by cutting down on yucky litter box smells. Also, from what we've found, people like that it doesn't need constant emptying, even in homes with several cats. Someone shared that the waste drawer can hold about a week's worth of mess from two male cats, which helps minimize trips to the trash can. Less hassle for you and a nicer, odor-free space for both you and your cats. A quick heads-up: the Litter-Robot 4 needs your cats to weigh at least 3 pounds each for the automatic cleaning to work properly. This design is there to make sure everything's running safely and smoothly. However, some cats might need a little time to get used to the sound it makes when it cycles. According to our research, this adjustment period can vary, but with some patienceā€”and maybe a few treatsā€”most cats get comfortable with it. All in all, if you're juggling multiple cats and want to keep litter odors in check with less upkeep, the Litter-Robot 4's a solid option. Sure, introducing your cats to it might take a bit, and you'll need to make room for it, but those are small prices to pay for a fresher-smelling home and lighter litter chores. --- *Where this comes from: This answer is based on ShopSavvy's product database, real-time pricing from thousands of retailers, and analysis of user reviews to give you a well-rounded picture.*
