This product is the end all, be all for cat lovers. It has saved my back and given my two cats a fresh place to go every time. It really does work! I was concerned that my power bill would jump due to the blow dryer but it didn't. In fact, I'm not seeing any significant change in either my water or power bill. This makes the cost of operating the CatGenie very economical, and my two cats don't often use the CatGenie in the same 10 minute window, so it will sometimes run after one goes and then the other one might go 10 minutes after it finishes cleaning and it cleans again. The Cat Activation Mode is the greatest; works as indicated and takes the guess work out of it.
I have only needed to replenish the granules once in the 5 weeks it's been operating and not by much. They do track the granules somewhat, but no more than regular cat litter; it doesn't bother me as much because I know the granules are cleaner than litter. I was finding little clumps of the clay cat litter on my carpet that I knew were dirty. The granules just look like little square pieces of composite material. They're very easy to clean up with one of the many brands of quick, 'powered sweepers', or the vacuum. My cats were used to an open litter box so I haven't tried installing the dome yet, which I'm sure would cut way down on the granule scatter that they ultimately walk in and track. If/when I try the dome I'm sure the tracking issue will be even less significant. The granules are completely dust free too. I am glad to not be breathing the dust anymore from the clay litter I was using that was '99% dust-free'. 1% dust is still bad.
The Tuxedo package is worth the extra for all the supplies you get with it. The installation manuals and user guides are very comprehensive. I'm thoroughly happy with this purchase.
