PetSafe Simply Clean Self Cleaning Cat Litter Box, Automatic Litter Box, Works with Clumping Cat Litter

Excellent product. Far superior to any other automated cat litter box. All of our cats adapted to it within hours of setting it up.My only complaint would be that the side of the rotating bowl is not tall enough to stop litter from being kicked out. However I believe I can remedy that pretty easily with some help from Home Depot, i.e., a strip of plexiglass about four or five inches wide and thin enough to bend into a circle without cracking it. I will then attach this band of plexiglass near the top of the side using duct tape or some kind of contact cement or such. This should add enough height to the side to contain flying litter with minimal effort and no real changes to the product itself.Until I can get this accomplished, it is noteworthy that the shape of the product after it is set up pretty much confines the cat using it to about an 18 or 20 inch long space on one side of the bowl, as the opposite side of the bowl is covered up by the conveyor that carries the clumps up to the retrieval bag after they are sifted out of the unused litter. As a result of this, virtually all of the litter that gets scratched out of the bowl lands in pretty much the same spot, making it fairly easy to clean up with a couple of passes of a stick type vacuum cleaner.I am also very happy to report that this product has no kind of comb or rake being used to clean the litter as do most other automated litter boxes. Said rakes and combs get gummed up with clumping litter and become fairly useless after just a few passes through the litter.This product operates by means of the rotating bowl forcing all of the litter through a grid, a little at a time. The unused litter continues on around the rotation path while the screen grid also guides the clumps into the bottom of the conveyor.The user manual states that the bowl makes one complete rotation every 90 minutes. This means of course that all of the litter in bowl is sifted once every 90 minutes as well. The litter in the bowl is also being constantly leveled out as the bowl rotates, despite how often your cats are scribbling their signatures into the litter.The conveyor is also interesting. Rather than a belt or such, there are some stationary strips mounted on a gentle rise. The top edge of these strips is scrolled with a wavelike pattern to prevent the clumps from rolling or sliding back down. In between these strips are other identical strips which are not stationary. These strips move up and down in a circular motion, similar to that of a horse on a merry-go-round. These moving strips pick up the clumps at one point and set them back down on the other strips a little farther up the slope. Thusly, the clumps sort of climb the stairs to the drop-off point.A very ingenious conveyor. Minimal moving parts and minimal likelihood of the conveyor becoming jammed up by clumps falling off the edge of the conveyor and getting wedged between a roller and a belt or suchlike.Hats off to the manufacturer, PetSafe, for their innovative idea, and extremely competent engineering of same. I would suggest to the designers a future revision of the product, simply adding about four more inches of height to the litter containment ring, which should not be at all difficult since said ring does not rotate with the rest of the bowl, i.e., the ring rests on top of the rotating bowl, seated on slick nylon slides to minimize friction, so that only the ring itself would really need to be changed to add height.When I purchased this unit, I recall reading in the hype that the bowl was deep enough to prevent litter from being tracked out of the bowl. Unfortunately, I don't think whoever wrote that statement, has actually had very many cats, if any, in his/her lifetime. 🤔The overall height of the side of the bowl from the bottom to the top edge of the ring is approximately 6 in, which understandably, might seem adequate height to prevent litter from being spilled over the side, if one has had little or no experience with cats . However, when it comes to selecting and preparing the spot they wish to use, and later covering up their business, cats are very energetic and fastidious about seeing that the job is done right from their perspective. 😼The height of the side of the bowl should be increased from its current 6 in or so to at least 10 in if not more. At the current height, virtually all house cats can walk in and out of the box simply stepping over the side as though it's not even there. 🙀Yes, it is true that increasing the height of the side that much would mean the cat would have to climb or jump a bit to get inside the box. But that is what cats do. In fact, it's their favorite pastime. 😺 So a 10-in high wall on the side of the litter box is no obstacle to any ordinary cat by any means. Even newly weaned kittens can scale an object of that height with little or no effort.Excellent product. Far superior to any other automated cat litter box.

You have already created an exceptional product. Making that adjustment to what you are currently marketing would make it just about perfect. 😏 😸.

This device didn't fail until last month (one year anniversary, go figure). I want to say at the outset that I was *extremely* happy with this device (while it worked). It performed so well, I could almost forget about the onerous cat-box chores.That said, I had the same reported failure in that the plastic cog that delivers power from the motor to the litter tray wore out. Unfortunately, I didn't hear the noise that I now know signifies teeth skipping. My cat, however, did notice. I figured that out when I put him near it, it made a knocking sound, and he ran away all freaked out. Apparently, that noise was enough to spook him. He decided instead to start abusing a corner in the room behind some furniture, which he soaked. I had to tear up that part of the carpet.Some points to consider:- I have low-dust litter, per directions, and it still collected absolutely everywhere inside the assembly. This was after my practice of taking out the collection bin and shoving a vacuum hose in there periodically. I took the device apart to try to fix it, and I found absolute sand dunes of litter and the large white cog stripped out.- There was even gunk caked in the teeth of the cogs. It would have been better to reverse the transmission wheel to let dust fall through to the floor than have a design where it was guaranteed to gather dust into the assembly. Even a little sweeper brush against the cogs would have been better than just waiting for it to fail.- There has to be a pretty significant amount of torque being applied to keep the litter tray moving, and a plastic cog against the smaller metal transmission cog isn't going to cut it. This will fail, and unless one is inclined to take it apart, you're either faced with hassling with a warranty claim or throwing your $130 away.- If you cat is easily freaked out, this might not be the litter box for you.All that to say I was very satisfied with this device until I realized I had been sold something with a guaranteed fail date and had to deal with a subsequent carpet replacement.Not happy.

works perfectly for 1 year 2 months and then.... broke ... is there a warranty???

Fácil de instalar, no necesita vaciar la caja de desechos más que cada par de semanas que se llena. No deja escapar olores. Es la mejor inversión en areneros para gato que haya hecho!!

This is a scam just don’t buy it. It will kinda work at first then it won’t.

I wouldn't order this as it is too much hassle to install it then at the end finding out they send a defective product and detaching it was harder than the installing.

This item is designed for the US market - 120V ONLY, with a flat pin plug. DO NOT plug it into 220V or you will fry the power adapter. If you wish to use it in Singapore, you will have to add a voltage converter from 220V to 120V, which I did. I alerted Amazon.sg about this problem, and advised them to remove the device from Amazon.sg, or at least make the 120V requirement clear in the listing, but they seem to have ignored my advice.As for how well it works, I like it because I only need to clean the litter box every couple of days instead of twice a day with a normal litter box. But it was cantankerous when I first started using it - although there is a line showing how much litter to put in, you can't expect to keep it exactly at that line all the time, and it took me some tries to figure out what was too little or too much, during which I had to disassemble and reassemble it to completely clean it. Since then, I've had it working for a month now with no problems.
