This CatGenie AI review starts with the thing most people miss: the A.I. and the Whoosh aren’t the same system with a few upgrades. The A.I. washes and reuses the same granules instead of continually replacing litter. The Whoosh uses a tofu litter that dissolves when it’s flushed, so you top it up over time.
Both flush waste down a drain, so there’s no bin to empty. This review covers how each one works, what owners report, and which trade-off suits your home.
The CatGenie A.I. washes and reuses its granules, while the CatGenie Whoosh scoops and flushes a water-soluble tofu litter that you replace as it runs low.
If you want to compare this system to drawer-style units, our best automatic litter box guide breaks down how they differ.
Quick Picks
Best for Reusable Granules Instead of Litter: CatGenie A.I.
Best for Faster Cycles and Less Tracking: CatGenie Whoosh
CatGenie A.I. Review vs CatGenie Whoosh
| Model | How It Works | Best For | Watch Out For |
|---|---|---|---|
| CatGenie A.I. | Washes and dries the same granules after each use | Multi-cat homes, skipping regular litter buying | Smell between cycles, drain blockages |
| CatGenie Whoosh | Scoops and flushes a water-soluble tofu litter | Faster cycles, cats picky about texture | Ongoing litter purchases, only approved litters work |
Is the Whoosh Actually Better?
It’s much faster. CatGenie lists a complete Whoosh cleaning cycle at about 7 minutes, compared with 34 minutes for the A.I.’s full wash-and-dry cycle.
Its cleaning cartridges also last longer. CatGenie rates each SaniSolution cartridge at 480 cycles in the Whoosh, versus 120 to 240 in the A.I., depending on how cleaning is triggered.
Owners who upgraded also report less tracking and cats that like the new litter more. But the A.I.’s biggest selling point is reusing the same granules, and the Whoosh gives that up. If that’s why you’re looking at CatGenie, the A.I. is still the one to get.
CatGenie A.I. Self-Cleaning Cat Litter Box
Why It Stands Out
Waste flushes away instead of sitting in a drawer, and some owners push that far. One runs 10 cats on two units and retired seven other automatic boxes. Another replaced three automatic boxes with a single CatGenie for four cats.
Those are owner stories, though, not the official guidance. CatGenie says it sees the most consistent success with about two cats per unit, and sometimes three, depending on the cats.
The granules are washed and reused, so you only top them up as they get kicked out or lost. There’s positive long-term owner evidence too: one owner’s unit lasted over four years, and another is on her third CatGenie across several homes.
It’s not silent. A light sleeper with two units beside her bedroom compares it to a washing machine you can hear but that isn’t loud.
Possible Downsides
Odor between cycles is the big one. Cats.com found it smells better after a cycle runs, but nothing controls odor before then.
Drain blockages are the most common hassle. Customer service is the weakest area in reviews, though one owner got a broken drain hook replaced free with no fuss. SaniSolution cartridges are an ongoing purchase.
Best For
Homes with a couple of cats, or larger households willing to add another unit if one isn’t enough, plus owners who prefer reusable granules and want waste sent to a drain instead of stored in a drawer.
CatGenie Whoosh Self-Cleaning Cat Litter Box
Why It Stands Out
The litter stays dry, which fixes a problem some cats had with the older machines. Owners report no more cats refusing the box after getting wet paws. One cat that wouldn’t touch the old granules uses the Whoosh litter without fuss.
A ten-year CatGenie owner says the old wash-and-dry cycle could create a terrible smell if bits of poop were left behind, and the Whoosh eliminated that. Another long-term owner reports far fewer clogs than on earlier machines.
Possible Downsides
You’re back to buying litter. And not just any tofu litter: CatGenie says almost all tofu litters are too large for the Whoosh’s sifting arm.
One reviewer reported a flood, so check every hose connection during setup. Some owners also dispute that it controls general odor well. The 8 to 10 year track records people cite come from earlier CatGenie machines, not this one.
Best For
Current CatGenie owners whose cats dislike the granules, and new buyers who want the flush-away system with a faster cycle.
Can Your Home Fit a CatGenie?
Both models need a cold-water connection, a toilet or laundry drain, and an electrical outlet. Each comes with an 8-foot water hose and a 10-foot drain hose, and Wi-Fi runs the CatGenie app, which is included for life.
The A.I. is about 19 inches wide and 21 inches high, and it needs about 24.5 inches of depth once the hoses are attached. Plan the spot before you order.
If you have one cat and want something simpler, the PetSafe ScoopFree or a globe-style box like the Meowant has fewer moving parts and needs no plumbing. If you’re transitioning a cat to any automatic box, the guide on getting your cat to use an automatic litter box covers the full process.
Frequently Asked Questions
Does the CatGenie Whoosh need litter?
Yes. It uses CatGenie’s Whoosh Super Clumping litter or Soy Sand tofu litter, which CatGenie has also approved. You add more as the level drops, keeping it between the line markers in the bowl.
Can I use cat litter in the CatGenie A.I.?
No. The A.I. only works with CatGenie Washable Granules, which get washed and reused. Whoosh litter won’t work in it either.
Is the CatGenie septic safe?
CatGenie says both models are septic safe when you use its approved supplies. If you’re on a septic system, check with CatGenie about your setup before installing.
What maintenance does a CatGenie need?
CatGenie recommends a maintenance cycle every 90 days for both models, or more often if your water leaves a lot of lime buildup. For the Whoosh, it also recommends taking the unit apart for a deeper cleaning twice a year.
Day to day, you’ll replace SaniSolution cartridges and top up the granules or the Whoosh litter as needed.
