PETKIT PuraMax Self Cleaning Litter Box with N50 Odor Eliminator, xSecure Automatic Scooping, Large Space Cat Box with Waste Bags

I have now had this for a few months but so far I haven’t experienced any leaking or other issues. I will create incremental updates (see bottom) to let you know how it’s going.I spent MONTHS researching and deciding on which robot litter box to buy. It’s a very large amount of money to spend for it to stop working either within a month or even within a year. My gripe with this device is that there were so few truly honest reviews from people who talked about the price because it seemed like the vast number of reviews and videos on the internet were of people who received it for free. When you get it for free, you just can’t really give an honest review because you weren’t the one to shell out so very much of your hard-earned money. There were only 2 reviews on the internet that I felt gave a fair and honest take and even those 2 were sent the item for free (though still honest because they paid out of pocket for other similar boxes so they knew the value of the cost and talked about it).I bought this box because of the shape (wide rather than tall), size inside (quite large), the location of the bin (on the side rather than bottom), height and size of entry (much lower & larger than others), and the rotation of the device (spin upwards rather and to the side). All of these made it closest to the current box my cats use so I felt they would adjust better since I was trying to minimize my need to contact customer support or return the item.I also bought the version of the kit with the bin deodorizer rather than the spray because of the price and the fact that I didn’t need the other things. The kits vary greatly, especially in price, so check out the versions carefully—there are versions that come with litter only, spray only, a bin deodorizer only, just trash bags, etc. My version only came with trash bags and the bin deodorizer. It didn’t come with the spray (I didn’t like the idea of this wasting space inside or spraying on my cats) or a mat (I already have one anyway). Incidentally, grocery bags work fine in the bin so you don’t need the bags. My version, “the new version,” came with the litter dump cover and the new fabric liner with the small lips to prevent leaking (an additional design implementation due to complaints of leaking and of scratching through the rubber). I don’t like the fabric because I’m not sure it will last as long as rubber would and I keep my cats nails shorter anyway but there’s no option to buy the rubber liner.1. Setup—I’m technologically capable and I found this device to be quite difficult to setup. There are ZERO written instructions, you have to watch a video that also isn’t very descriptive, pause and stop frequently to be accurate, and most importantly, you need the app for proper set up. I foolishly thought I could set it up manually with the buttons and install the app later. Even still, none of these various methods tell you whether you should add the litter in first before powering on or how to zero the scale. Even setting up through the app was strangely difficult, the prompts are not native or intuitive, it’s very easy to click the wrong thing and then difficult to figure out how to go back to start over. This is probably due to translations not being quite accurate. I was able to figure it out but I believe it was far more difficult than it should be and might be much more difficult for others than it was for me. My suggestion is to go slowly at each prompt and think a little about what it’s trying to ask. I can’t really explain it any better than that.2. Leaking—So far, I have not had any leaking issues and I have read that this might be a more frequent issue for those with male cats who have a different urinating stance-I only have female cats. To combat this, at the initial setup, I placed a wee-wee-pad at the bottom, making sure to fold it so it did not cover the rotation wheels. Sticking out a little in the front and back does not seem to affect the rotation. I wonder if leaking becomes an issue the longer you use the device because of the fabric (as opposed to rubber) liner which degrades over time. I’ll update later if this is something I discover. I also wonder if it occurs if you don’t add enough or frequently replenish the litter to absorb the urine. I fill to max level and add once a week. We shall see how this works.3. Dimensions—The measurements are NOT accurate. It is at least an inch larger on each side, maybe more, and definitely more if you factor in the actual clearance it needs to work (not blocking your ability to pull out the bin,the rotation, and even the infrared sensor). If anything is too close (even if not touching), it will not work. I live in a small apartment and have limited space so I had to rework the space quite a bit, removing molding, shelves, etc.4. Functionality—In the past few days, I have found this device to be extremely quiet and aside from the setup, very easy to use. My cats took to it fairly quickly (I used their old litter from the prior box to help with this) although they are still very curious when it rotates. It’s not great at properly measuring your cats weight and has never shown it to be the same weight twice. It often just shows up as “unknown cat” and I have to guess based on the approximate weight of my cats, unless I know based on having observed the cat myself.Recap—be careful of the reviews and look critically when buying; be aware of the large size; be aware of complaints of leaking and how you will deal with this; and finally, factor in the strong possibility that you will not get much customer service. Overall, I am quite happy with it so far and believe it to be worth the money if it keeps working as well as it has so far.EDIT 1 MONTH—I have noticed that my cats kick out SO much more litter than they ever did before. I believe this is bc the PETKIT box has a grate at the back that cuts into the space so cats have to shift the opposite way, much closer to the entrance, thereby kicking out litter. This is worsened by the fact that the entrance is low and large. It’s not a dealbreaker but something to be aware. It’s a lot of litter. Everywhere.EDIT 3 MONTHS—Still no leaking but I have also noticed that my box is significantly scratched up on the top of the drum in a straight line from where the wheels touch the top as it rotates. I believe small bits of litter dust are getting on the wheels and then scraping the drum. Also not a dealbreaker but something to be aware of if you are concerned of aesthetics. If so, you may want to consistently clean beneath the drum and/or wipe the wheels.EDIT 6 MONTHS—Still great but I’ve learned more tips. The effectiveness of the cleaning has a lot to do with the kind of litter you use and how you set it up to clean. The better the litter is at clumping, the more effective the box will be. If you don’t let the litter sit long enough to clump properly, the box will only smear the waste or crumble the clumps. I use World’s Best litter and set it to clean 2x a day at specific times (once in the morning and once in the evening) when I know my cats are usually sleeping and not as active. I have also discovered that it is terrible at properly gauging cat weight when it gets lower on litter so you really have to properly replenish the litter. Once I do that, it gets a little better. HOWEVER, they don’t specifically mention this but you MUST set the device to maintenance mode before adding litter. If you try to add it directly, it will mess up the calibrations.

Edited a year later... I just threw this piece of trash away.One, this litter box will constantly say it's "in use" by your pet when it's not. This prevents you from cleaning, filling, or performance of any maintenance because the machine will freeze and refuse all commands until it thinks the nonexistent cat is gone.They put the cat presence sensor under where the cats enter. So it gets filthy and stops working. Heck, I found out a bright ceiling light will trip the stupid sensor.The software is garbage. The directions don't even mention the side hood being removable and how to go about getting the robot arm unstuck, which will happen when a clump of litter gets in there...which is literally every time the machine dumps clumps to the collection bin.Today I couldn't get the machine to stop insisting a cat was present while attempting to add litter. The power cycle workaround wasn't working, cleaning the sensor window wasn't helping... I had enough and threw it in the garbage.In short, I do not need a machine fighting me at every turn when trying to scoop poop. I have no desire to spend my time digging in dirty robot parts trying to get the stupid thing to stop insisting some facet of itself is not right so it'll run again.This machine is a frustrating, poorly designed, box that'll really increase the time it takes to clean a pan. I don't need that. Good riddance.This is my first robot litter box. It took me a long time to order a robot like this, as they cost so much - and it's a litter pan. But I did it, and this one is data fancy and that's nice. The unit has weight sensors on all four corners which are used to monitor your pets usage. The app does a surprisingly good job - for a pretty janky app - of not only functioning, but displaying cat usage data. You can track litter use, multiple cat weights and their usage - there's graphs and a good amount of granularity. The box itself is nice, very very quiet, and seems easy to use so far (after 2 weeks of use). It's big enough inside for my tabby, who is a big long cat - he needs room.
