The Maintenance Cartridges makes the maintenance on the catgenie a lot better. I can tell when I need to run the maintenance cartridge because the tips have to be cleaned every few days if this hasn't been done. So you can't have the CatGenie without this product! Thanks for making it:) Don't know what I'd do without it!!
I did notice though that after using it the 4 times it still has some cleaning fluid left in it. Is this supposed to happen? I tried using it one last time & it wouldn't work. I forgot to document on the cartridge how many times I had used it and when I tried to run it the last time, since it still had some left in it, I thought that I had only used it 3 times. But since my catgenie wouldn't do the maintenance cleaning, I assume that it must not have enough in it for one last cleaning. This is the only thing I can think of as to why it wouldn't do the cleaning since all my regular cleanings it works ok.
