Review: Best Bot Ever! - After a few weeks of usage I can at least say for now that this unit is amazing. I have owned many auto litter bots and this is far superior in every way. There is NO work involved here. The dirty litter bin is very large. Great for multiple cats. The way it closes after every cleaning keeps the smell down and I love how I never have to change the bagging system. It seals the litter bag when dirty and you remove the old one and it auto sets the new one. Amazing. The camera works great. Records everything very well. I got this bc I have a cat in kidney failure and I need to know his habits. Has been very useful for that. The unit itself is actually very compact considering the large size of the toileting area. I’ve had full service units before and usually they are just bulky awful sized units. Not so with this one. And I love that the litter capture is in the back of the unit. I feel like this unit sets the new standard for what auto litter boxes should be. This was actually worth every dime. I’m actually considering buying another one. ***** I wanted to add an addendum to my review that I have three of these now and I have had them for over a year and never had any issues. I also see a ton of people commenting that they have issues with using it for larger cats and I have a cat that is extremely large in stature and weighs about 20 pounds and he uses it with no issue. I have a wide variety of pets and there has been zero problems with using these units for any size cat. So I really don’t get the issue that other people are having. I can truly say these were a good investment because they still work perfectly after all this time. I have never had any other automatic litter box work for this long. I couldn’t imagine going away from these litter boxes at any juncture in time unless they come out with even greater improved model models that have more functionality.
Review: Great Investment - 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.

### ⭐⭐⭐⭐⭐ ⭐️⭐️⭐️⭐️⭐️ Great first automatic litter box — really impressed
*by A***E on April 28, 2026*

This is my first time using an automatic litter box, and honestly, I’m really impressed with the Petkit PuraBot Ultra. Setup was pretty straightforward, and it’s been super easy to use day to day. The app is clean and intuitive, so I didn’t have to spend time figuring things out. One of my favorite features is the auto bagging—it makes cleanup so much easier (and less gross). I barely have to think about it, which is kind of the whole point. The camera with facial recognition is surprisingly useful, especially since I have multiple cats. It’s nice being able to see which cat is using the box and keep an eye on their habits. I also like how the litter box rotates left and right to cover the waste before dumping it. It actually helps keep the inside cleaner since things don’t stick to the cylinder as much. Overall, it feels like a high-quality, well-thought-out product. Definitely made my life easier, and my cats adjusted to it pretty quickly too. If you’re on the fence about getting an automatic litter box, this is a great one to start with 👍
