Our Video Review

Did our cat Fozzie like it? Let’s find out….



As our top rated self-cleaning cat litter box on the market, the Open Air is chalk full of great features. People love this box and for a good reason. This litter box does its job really, really well.

You could also write a whole book on all the features found here, but we wanted to lay out our top five unique features of this model. You’ll find them below:

  • Wifi-eneabled

Do everything using your phone! view the waste drawer level, get notifications, troubleshoot, and see recent usage history for insights into your lovely cat’s health.

  • Automatic Everything

If you’re looking for an automatic cat litter box that just works, then the Open Air is for you. Everything in this box is automatic. When you cat steps in the Open Air III, there’s a sensor that automatically stops any cleaning and lets your cat take care of business. Once you cat exits, the box automatically begins cleaning again. Then the waste is automatically disposed of in a storage area.

  • Ideal For Large Cats

featuresMany automatic litter boxes do a good job. There’s only one problem: they aren’t made for cats of all sizes and certainly cannot handle multi-cat households. The Litter Robot changed all that. Not only does it do its job well, but the unit is designed for large breed cats and multi-cat households. This thing can take anything your furry friends can throw its way.

  • Simple Setup

Well, it’s more like no setup at all. This unit comes fully assembled. You legitimately take the thing out of the box and plug it in. Your cats can now use the litter box without worry. It really doesn’t get easier from a setup standpoint than this.

  • Once a Week

My personal favorite thing about the Litter Robot Open Air III is the once a week maintenance I have to do. Once a week, I have to open the secluded waste container and switch the bags. Then I take the bag into the garage and throw it away. The whole process takes two minutes. Then I’m done dealing with the litter box for another seven days. It’s that EASY. There’s no changing of litter require or anything.

  • Cats Love It

I was a bit skeptical that my furry friends would like this unit. The design is entirely different, and I was concerned I’d have to train my cats to actually use this automatic litter box. That all changed the second day the device was in my house. My cats immediately adapted to this unit and started using it. They loved it from the outset and we haven’t had any issues adjusting at all.

No automatic litter box is perfect, especially as we all have different needs. While the Litter Robot comes pretty close, it’s not perfect, either. Here are a few things we didn’t love about this device:

  • Huge litter box. You’ll need a decent storage space for this one
  • Heavy design is hard to move around
  • Specific litter needed in the box can be difficult to determine
  • This box is one of the pricier ones we’ve tested
  • Cats sometimes end up hanging out in the box instead of relieving themselves and leaving. Our cat, Fozzie, did it a few times…

We’ve tested a lot of litter boxes over the last couple years. None of them are perfect. Each device has its own unique set of issues and problems. However, we’ve found that the Litter Robot Open Air III is the best automatic cat litter box on the market. Bar none!

This litter box just works. Everything the manufacturer says this box can do, it does well. If you’re looking to avoid contact with cat waste as much as possible, then this is the box for you. Not only will it save your from nasty smells, but you’ll also not have to waste any time changing the litter box. It’s truly a win-win for cat owners!

Our Final Rank: 4.85/5
