## Description

PETKIT Trash Bag Refill Rings for Purobot Ultra Auto-Packing Self-Cleaning Cat Litter Box, Leak-Proof Replacement Waste Bags, Long-Lasting Trash Bags -4 Packs

Review: Great go to for for PETKIT refills - If you have one of these boxes, then you know you absolutely cannot run out of bags! These come in a 4-pack and work well. They nest together for easy storage with a paper tab to keep them from catching and pulling out. Odors are controlled by the sealed doors on the unit and the odor blocking cube. These are a good value to keep your unit running. I’ve only had one or two issues out of several sets where the bag didn’t hold up or complete refilling correctly. I believe that’s more of the machine error than the bags themselves as it cuts and thermally seals during the process.
Review: Factory originals. - Factory units. Easy to replace per design. Works well. I have found some problems in certain individual units. The first one with the unit had holes in about four of the bags. The second had no problems. The third had three bags break as I took them out. My guess is they have different manufacturers or lots that dictate quality. With that one thing said - these ARE great. They fit perfectly. They recognize by the machine. They work.

### ⭐⭐⭐⭐ Had a hard time loading
*by W***Y on 6 August 2025*

I'm pretty sure this is an authentic product from petkit but my little box had a hard time "loading" the bags. It took a few tries to get the little box to use the bags. Maybe my litter box and now the bags/ring?
