4 Pack CatGenie Machine Maintenance Packs- Works in both CatGenie Models
Product Review (submitted on January 27, 2014):
In my experience these clean much better than the cartridges.
It's an easy process -slightly more involved than switching out sani-solution but the results are worth it!
My genie is running/smelling like new again! My cat's & I approve!
Plus, I know I'll get 4 deep cleans vs. the 3 not as deep from the maintenance cartridges. They claim to provide 4 but my genie wouldn't run the last one because it thought the cartridge was empty even though it wasn't.
