We have had the litter box for a month and it works excellently. It is very easy to assemble and has detailed instructions.
It took our cat a few days to get used to it. We placed the new and the old litter box in the same spot together for 2-3 days, and because our cat chose the old litter box, I put some used litter into the new litter box every day so it could pick up the smell, and then I completely removed the old one. The same day I removed it, I put her in it in my arms and she used it. Since then, she started using it normally.
During the first days when she started using it, I had it on manual cleaning mode and every time I got a notification that she had used the litter box, I cleaned it. When it is on manual cleaning mode, if the cat is on top of it, it does not let you clean it. After I saw that our cat kept using it, I switched it to automatic cleaning mode and now it works normally on automatic without any problem. We went on vacation and it worked remotely and I got notifications for every movement of our cat. We bought it without the step, and our cat climbs in without difficulty (adult, 6.5 kg).
The sensors work very well because even when it is cleaning, if the cat comes near, it stops and waits for her to move away before continuing.
Another positive is that it does not make much mess around the litter box; it gets only a little dusty and can be cleaned easily with a baby wipe. Externally, of course, since it is open, it gets quite dirty, but with a mat I think there will be no problem.
The litter should be up to the max line, and although I was worried it might not be enough for our cat, who likes to dig, it seems she has no problem with it.
The app is very good and easy to understand regarding cleaning as well as information about the cat; after a few days it even recognizes what the cat is doing when she uses it.
As for the smell, the deodorizer does its job because there is no strong odor even though the waste is in the basket. We are changing the bag once a week for now. If the deodorizer starts to weaken before we replace it, we may change it more often. It is still too early to judge.
Overall, we are very satisfied because the cleaning work is done easily and our cat always has a clean litter box. It also gives us greater freedom when we are away.

Update after two months of use!

ATTENTION CAT PARENTS. If you choose to buy it, get it with its step or a step that is large enough! We put a small step that didn’t suit our cat, as a result she would jump out and eventually injured herself (not seriously) in her back legs! Now we have put in a step and thankfully everything is fine!

Other than that, we are very satisfied and it does what it promises without causing us any problems.

Well, we’ve had the automatic litter box for 8 days and I have to say that it is an excellent, high-quality product.

The positives
1. Excellent value for money
2. Very good build quality and quality
3. Very nice design
4. Complete instructions and adjustment sheet
(My one cat accepted it almost immediately, while the other needed days and a methodical approach. Specifically, 3 days unplugged; as soon as she started going in, I would give her a treat to encourage her, and then little by little I would place her at a safe distance to watch the cleaning process. And of course I have left the old litter box out so she feels safe.)
5. Easy to use for daily use
6. Comes with an odor filter and bags for the bin.

The negatives
1. The height of the device. (They jump to get out even with a step in front)
2. The app needs improvements: The mobile app, although useful, still needs work on the software side. It is not always as smooth and user-friendly as it should be and often makes mistakes in recognizing my cats, confusing them with each other.

Nevertheless, I believe that if you do not have an elderly cat (who would have an issue with the height of the litter box), it is worth buying! It is the total value-for-money choice!
