While for the most part I’m happy with the litter box and all of its components. The litter sticking to the rake and the back of the cylinder has been the Bain of my existence. I keep it really clean but it still happens and that’s when I get a smell. I am happy that my cats have fresh litter when they use it. So the inconvenience of pulling the rake out constantly to clean it is worth their comfort. I also have the step that catches litter. It’s gigantic for the box. I have ish it was half the size. I live in an apartment and it takes up significant space. I will probably get rid of it soon. It’s okay for the task it does but it really is too large. All in all this was a good purchase. I like that you can replace parts and take the whole thing apart and give it a good wash. It moves slowly so there is not as much dust. The bags are strong . The air freshener is great. The air drainer for the litter drawer worker really well.
