Less dust
I love my cat, but there are several things that I dislike:

1. Buying "sifting" litter liners
2. The smell of cat droppings
3. The dust

The dust is really what I dislike the most! Before the Omega Paw RA20, I would use the sifting litter liners to sift out the clumps. The problem is that the dust gets everywhere. I smell the dust in the air, on my clothes, and in my nose.

With the Omega Paw RA20, I roll the box, take out the poop tray, throw the clumps in the trash can, put the poop tray back in, roll the box again, and put a heavy duty air purifier in front of the litter box entry for a few minutes. This keeps the smells and dust at bay.

I also liked the price. The Omega Paw RA20 is several times cheaper than the electric litter boxes.

Works great, just as advertised!
What can I say? It's fairly inexpensive, and simple. You don't really need super special litter or anything, it works great for my Mom and her cats. The smell in her house is gone! Yay! Way better than the motorized one I used to have.

Awesome
My husband is deployed and I am pregnant so cat litter and I aren't buddy buddy. Anyway we tried the Scoop Smart: waste of money, messy, more work than a traditional litter box. Then I came on here and read all the great reviews about Omega Paw. So I talked to the hubby and went to Petsmart to get one right away as I was so tired of the cat clamps all over my floor. I couldn't believe how quick and easy it was to set it up. I tried the rolling thing to do and not one grain of litter fell out of the box. Then my female cat went in to do her business and she seemed very content. I am just so relieved that I won't have to get rid of my cats because of the fear of toxoplasmosis. Simple system but smart system!

it really is AMAZING
This is quite possibly the greatest thing ever created. After my $200+ electronic self cleaning litter box was a disgusting (literally, disgusting) failure, I saw that this one had good reviews and was much much cheaper, and immediately ordered it. After ordering it, I started reading reviews and saw some where people somehow just didn't like it... man, i feel bad for them. They must be doing something very wrong, I don't see how anyone could not love this thing. I have 3 cats and they poop a LOT, and all i have to do is turn this thing over once a day and it cleans everything within minutes. Every 2-3 weeks i take it all apart and clean the walls, and I never have any smell to deal with. I noticed people were complaining about the clasps breaking, so i rarely touch them, and when I do, I am very gentle.. no problems there.. I also saw some people were complaining about litter falling through the cracks. Well, they must have it attached wrong or something. Only sometimes do I have any litter fall through the side, and when i do i just shake out the mat that I keep under the box. Cleaning the litter box is actually entertaining now! I laugh every time i use this thing because of what a pain cleaning the litter used to be, and how easy it is now. And to top it off, I actually save a lot of money on litter. I strongly suggest using Precious Cat Ultra Premium Clumping Cat Litter, as it has worked great for me. Buy 2 bags from amazon so that you get free shipping. The one negative thing is that my girlfriend is too weak and frail to turn the litterbox to clean it, so if you don't have someone living with you who can do it, then you shouldn't get it. (It is extremely easy for me to do, and you have to be very weak and helpless in order to not be able to do it.) So PLEASE take my advice and GET THIS LITTERBOX. I swear it has changed my life!

Simply Awesome
This is such a simple concept and it works amazingly! All the self-cleaning boxes with motors end up breaking and jamming. This is so easy to clean and only takes a couple minutes. Definitely worth it!!
