Our verdict
A compact, lightweight version of Omega Paw's rolling litter box, best suited to smaller cats or homes where a regular-size, lidless box makes more sense than the large model.
Owners with a single smaller cat who want an affordable, no-electricity litter box with a smaller footprint than the large Omega Paw models.
Skip if

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 Omega Paw NRA15 is the regular-size version of the brand's rolling self-cleaning litter box, measuring 16.5 by 18.5 by 17 inches, noticeably smaller than the large NRA20 and Elite models. It has no lid and is built from polypropylene rather than the plastic used on the larger units, bringing its weight down to 4.5 pounds.
The cleaning method is the same roll-to-sift mechanism as the rest of the Omega Paw line, with the top, bottom, grate, and scoop included, and no electricity, liners, or filters required. It carries a 3.8 rating across nearly 16,800 reviews, the largest review count of the three Omega Paw entries here, though it also sits at a slightly lower rank of #145 in Self-Cleaning Cat Litter Boxes.
At $51.60 it is the least expensive of the Omega Paw options, which makes sense given its smaller regular size and lighter material. For a household with one cat and a preference for a smaller box, this is the most budget-friendly way into the Omega Paw rolling system.

Performance notes
Built from polypropylene rather than the heavier plastic used on the large models, the NRA15 trades some bulk for a lighter, easier-to-roll unit at 4.5 pounds. Its 16.5 by 18.5 by 17 inch footprint is smaller than the large-size Omega Paw boxes, which is worth checking against your cat's size before buying.
What buyers say
With close to 16,800 reviews and a 3.8 average, this is the most-reviewed Omega Paw model here, and the slightly lower rating compared to the large models may reflect its smaller size being a tighter fit for some cats.
How does the regular size compare to Omega Paw's large litter boxes?
The NRA15 measures 16.5 by 18.5 by 17 inches, smaller in every dimension than the large NRA20 and Elite models, making it a better fit for smaller cats or tighter spaces.
Does the NRA15 have a lid?
No, this model is listed with no lid, so it's an open-top design rather than a covered box.
What material is this litter box made from?
It's made from polypropylene, which keeps the unit light at 4.5 pounds, useful since the rolling mechanism requires physically tipping and rolling the box.
