The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less.

Overview
The CleanWell 4393 comes from BISSELL, a brand better known for vacuums than litter boxes, and it shows in the build: a 25 pound plastic unit with a 21.18 by 28.43 by 24.69 inch footprint that leaves room for a genuinely large XL waste bin rated for about 20 days between changes. That bin size is the headline feature, since it means far less frequent trips to empty it compared to smaller self-cleaning boxes.
OdorVault technology handles smell containment, sealing waste away from the room, and the unit is smart home compatible with app control so you can trigger cleaning cycles and check on usage remotely. The health monitoring feature tracks litter box visits over time, which can be a useful early flag for changes in a cat's bathroom habits.
At $399.99 this sits at the higher end of the self-cleaning litter box category, and the open-top design (no lid) trades privacy for easier cat access and simpler cleaning of the unit itself.

Performance notes
Dimensions run 21.18 inches long by 28.43 inches wide by 24.69 inches high, and the unit weighs 25 pounds, both on the larger side for the category. The plastic black housing and open-top layout keep the design straightforward, while OdorVault odor control and the 20-day XL bin are the two features doing most of the heavy lifting on day to day convenience.
What buyers say
The 4393 holds a 4.0 rating from 27 reviews, a small but positive early sample. A bought_last_month figure of 400 suggests real recent demand even though the review count hasn't caught up yet, which is common for a newer listing.
BISSELL rates the XL bin for about 20 days of use, though the actual interval depends on how many cats you have and how much they use the box.
Does the CleanWell 4393 have a lid?
No, it's an open-top design. That trades some privacy and odor containment for easier cat access and simpler maintenance, with OdorVault technology handling smell control instead of a cover.
What does the health monitoring feature actually track?
It logs litter box visits through the connected app, so you can spot changes in frequency that might be worth mentioning to your vet.
