The media could not be loaded. We bought this while it was on sale and made an impulsive (though mildly informed) decision and bought this. We have 3 cats and having to bend down and scoop poop, especially after a long day of work and some mobility issues. It's functions are fully customizable and work pretty dang well. It's UI is really easy to understand and is intuitive for the most part. Navigating the menu on the LED on the litter box isn't as much, but it's mostly due to the double-click confirmation. You scroll through the menu, then single click the option, THEN double click to confirm. I'm sure it's a safety feature but it took me sec to figure that out since I kept getting frustrated that it wouldn't go through. The robot is pretty damn big, about 2 regular bots wide and length, considering it's functionality, so expect it to take up a good amount of space. Now, about all the subscriptions you'll be presented with with it's many moving parts. The cloud service it has is relatively useful, but considering it locks the extra functionalities behind a subscription, it's a little frustrating. The filter for the trash receptacle is relatively cheap to replace and it does a damn good job at covering up the smell of the building trash bag. The bag needs to be packed every 2-4 days depending on the cats' frequency which isn't all too bad. The gripes I have with it are few. One issue I came across is the packing functionality works mostly fine, using heat to melt the bag-ends and sealing the bag. I had an issue where the robot did NOT do a good job of splitting the sealed bag from the new part of the bag and it ended up with me prying it apart. The full bag was fine but it ended up creating a tear in the refill, thus rendering it completely useless (unless I missed a way to re-seal it or find a remedy.) I had to refill the ring with a new, non-torn one and that's money down the drain. Overall, I'd consider it a great purchase and would highly recommend it to anyone who's got the money and who needs a little extra help around the house.

I’ve been using PETKIT products for years, and they’ve always been reliable. The PuraBot Ultra is by far the best one I’ve used. Setup was fast and simple. The app connects easily and works without issues. My cat adjusted right away. It’s very quiet, and the odor control is excellent. I don’t need to scoop anything, and the waste bin holds plenty. The self-cleaning is smooth and mess-free. The design looks modern and fits well in my home. I also like how the app tracks my cat’s usage. PETKIT has once again made a high-quality product I can count on. Highly recommend it to any cat owner who wants less mess and more peace of mind.

The Petkit Litter Box is an absolute game-changer for any cat owner! From its sleek, modern design to its incredibly functional features, this litter box exceeds expectations in every way. It effectively eliminates waste, keeping odors at bay and ensuring your home stays fresh and clean. Plus my absolute favorite thing, the safety features, my kittens use it like a playground at times and if it is in the middle of cleaning it stops immediately. Totally recommend it! Worth every dollar! Overall, the Petkit Litter Box combines convenience, efficiency, and technology in a way that makes maintaining your cat's hygiene very easy. It's definitely worth the investment if you want a clean, odor-free home and a happy, healthy cat!

This is a great functioning basic version of the expensive ones. Does it scoop perfectly? No…leaves a few tiny bits. But neither does the $700 one scoop perfectly. Easy to use, easy to empty. No odor control so I spray the litter daily with essential oil spray. No phone app but I didn’t care. The real great thing is convenience! With one cat, we empty twice a week and could probably go longer but I worry that the fussy cat might decide it’s too stinky to use! Buy this one. It’s a keeper.

Sadly, this incredible technological marvel did not work for us. We have three cats, two of whom are mid-sized kittens and one average-to-large-sized elderly 14-year-old Tuxie. The kittens fit fine, of course, but the 14-year-old had two accidents where he faced the inside of the litter chamber with his hindquarters sticking out, and he urinated all over the floor. It is actually shocking to me that the chamber is so shallow as not to accommodate a larger cat! Given the cost of this machine and the fact that my big boy is really rather average-sized, you would think this would have been addressed. We bought this automatic litter box for him, because he gets very fussy if his litter isn't pristine. He will often pee or poop outside of the box if the cleanliness of the litter is not to his liking, so naturally, the self-cleaning feature is a huge plus! The app, the self-cleaning mechanism itself, and the rings were super easy to use, and the quality is top-notch. I can't begin to describe my disappointment. The fact that I was willing to pay this much money for a litter box should be telling in itself. Our oldest has also had a history of urinary crystals, so I was really excited to have a way to monitor his urination and to track the other cats' habits, as well. The first thing the vet will ask us is if they are pooping and peeing ok, and with multiple cats using a conventional litter, how would we know? This technology enables cat owners to track all of their cats' elimination habits and also the cats' weight. If the design is ever improved to accommodate a larger (albeit average-sized) cat, I would totally try this again.

Got it right before i went to my vacation. I recently went on vacation over the July 4th holiday for 5 days, and this automatic cat litter box made things so much easier. It worked perfectly while I was away—no mess, no smell, and my cat adjusted to it without any issues. Knowing the litter box was being cleaned regularly gave me peace of mind during my trip. Super convenient and definitely worth it if you travel or have a busy schedule!
