I ordered Litter Robot first but it didn’t ship out even after 1 month. I ended up canceling it.
I really wanted an automatic litter box though.
I spent hours online try to find new auto litter box and came across Petree. I saw few scams so I was kind of skeptical but decided to trust the reviews on here. I placed an order and got it within a month. I love that I decided to give this one a shot, for real. It came in as complete product so I didn’t have to install or anything. All I needed to do was to put a plastic bag into the litter tray and plug the machine into the power outlet. Instructions were simple and easy to follow. I have one cat and I empty the tray within every 2 weeks. I don’t smell a thing unless I open up the litter tray to empty it.
Here’s numbered reviews for your convenience.

Pros:
1) it looks so cute and sleek
2) it’s very quiet
3) it tells the kitty’s weight
4) it’s light
5) it doesn’t leak the smell at all
6) I separate the globe from the motor bottom and can water clean it
7) it’s delivered as complete product so there’s no need of any installation
8) litter tray can hold any plastic bags
9) but they do give free grey-colored roll of bag
10) litter box is always clean !!!
11) but I don’t need to scoop at all !!!!
12) it has sleep mode so it won’t operate for 10 hours during your quiet time
13) it’s reasonably priced compared to other automatic litter boxes out there
14) it’s small enough to not interfere with home interior but still big enough for an average sized adult cat
15) they give free litter mat !!!

Cons:
I can’t really think of anything... but if I have to say something...
1) it will be nice if there’s door attached for less dusting?

This was a GREAT purchase! I had a Nature's Miracle automatic litter box before, and that thing made a mess everywhere, stunk to high heaven, and SCREAMED every time it operated! I was at wits end. I started looking up replacement options, and found Petree. I love this thing! It's so quiet, I have it set outside my bedroom door, and it never bothers me. It's clean, there's no stink, and my cats love it! (As much as cats love anything short of wet food and treats, anyway...)

I actually moved my Litter Robot out the moment this arrived lol. The moment I laid eyes on it I loved it!! Super sleek design and works like a dream already. SO much quieter. Wish I'd found this years ago when I'd bought my litter robot so I could have got one of these instead-- just a much better fit for our lifestyle and household and much less issues

I love that this machine cleans itself. I hate scooping litter so this is a godsend. I had a cat genie before a few years ago and loved it but in my new place I have no where to put one. This one is better because I don’t have to hook it up to a water source. It’s quiet and gets the job done.

Very impressed so far with this Petree litter box. Love the fully enclosed design as I used to have a litter box with no cover and the smells get very strong if I did not clean it timely. The storage tray for cat waste and the free bag liners are my time-saver! I only have to remove the tray for disposal. The way the hood rolls up for scooping is so much better than removing the whole lid, and the opening is very large. Overall this is the best cat litter box I have ever had.

This thing is seriously life changing and wish I had discovered it so much sooner.
I have 3 cats and daily scooping/cleaning 3 regular litter boxes was starting to kill my back. This thing was so incredibly easy to use every day, once I got the hang of using it properly, that I am happy with this purchase to replace regular boxes. I am ocd clean person so the litter bits left behind makes me nuts. But this self cleaning litter box is definitely one of the best things I’ve ever discovered and I have tried a TON of different boxes. I love it and will never EVER own another litter box other than this one!!!

I needed a second box for indoors. I have an electric, self cleaning box on my patio. But indoors, I wanted something I could easily clean daily and be more sanitary. This PETREE litter box is so easy to clean and keep fresh. It's great!

It is a very good litter box. The construction was easy and it works exactly as described, and cleaning the litter box is fast and easy. I've only used one other litter box (open tray) once before switching over to this, and from the comparisons I can make, there is much easier when using the Petree Self-Cleaning Litter Box. Although it is kind of expensive for a box that holds poop (still much cheaper than litter-robot III), it does make cleaning the litter box a much less annoying process and I totally recommend it.

We love the look and size of this litter box. It is big enough to do its job, has a big enough receptacle, is fun for the kitty and he went right into it. Thank you!

Got this for my two kittens and it works well so far. Great for multi-cat homes friendly. Self cleaning after each use. No special bags or liners needed. Only issue is I’m not sure how to replace the litter, so I’ve just been refilling it as time goes on.

I adopted him the day before my litter box arrived. He's a 4.5 year old, 11 pound, medium size cat with trauma caused by kids in his past home. I didn't know if he would like the litter box but he took to it right away! This PETREE litter box is very convenient, keeps litter off of the floor and also makes cleaning the litter box slightly more enjoyable. The design is also very eye catching and great for the home. Works better than I hoped!

Very impressed with this PETREE litter box. I used to have a litter box with no cover and the smells get very strong if I did not clean it timely. The PETREE innovative design makes it easy to clean. It has bags to line the receptacle, so that you can clean the box more frequently then just pick up the bag and throw away. I love the modern look of the box, and the fact that there is a carbon filter to eliminate odor. This is cute and doesn't look like a big ugly box, it looks like a little space capsule. I love this litter box. It is super cool! Overall this is the best cat litter box I have ever had.

I love this automatic cat litter box. My cat would go poop on the carpet in the living room. I hated how I had to see smell and sometimes touch nasty gross used poop or pee litter. Considering how much it cost, I searched on Google, compared several prices, chose this Petree litter box, it's amazing. With this self cleaning little box, no smell to linger. I only clean the waste drawer once a week. Save much time, thanks.

I need the full instructions for the cat shit machine that is in AMERICAN SO I DON’T HAVE TO GO TO CHINA TO LEARN HOW TO READ IT,
Do you do this to every one that that buys this

I have been using Petree for 3 month now and wow this machine is amazing. I have three cats and two of them started using it right off the bat, the third one took a little longer; but they are now using it on a regular basis. It's just nice that I don't have to scoop their litter 3 times a day any more. All I have to do is clean the collection tray once a day. I strongly recommend it to anyone who has fur children - you won't regret getting it!

I have had Petree for more than a year now. Honestly this machine far exceeded my expectation. I have used many of the automatic litter box on the market including CatGenie, Litter Robot and Litter Maid. This one really fixed a lot of the problems other machines have. 1.Error Beep Noise: if you have used automatic litter box before you'll know this is a big issue. Especially when you sometimes hear error beeps every other day it makes you wonder whether you should just scoop litter yourself. Petree has no such issue. During the one year of my usage I only saw error message once and that was when I was moving. I fixed it immediately after I restart the machine. Besides this one has a very low voice when it rotates so it can be put even in your living room. 3. Easy Install: all I had to do with petree is to put on the plug and pour some litter inside . It activates immediately. No need to connect hose or download some stupid apps to get it started. It is simple but effective.
