Oneisall CB01 Self-Cleaning Litter Box vs Oneisall Ease S1 Self-Cleaning Litter Box

Both are the same Oneisall open-top self-cleaning box with an 11 L drawer, silicone liner and 10-second detach, so the real choice is the step. The Ease S1 adds a beveled step and ramp that help kittens, senior cats and heavy cats get in and out, and it cuts litter scatter. The CB01 is the plainer box with the same cleaning hardware. Owners of both praise quick setup, quiet running and easy deep cleans, but ratings are thin, so treat the 4.1 as a small sample.

• Choose the CB01 if your cats jump in and out without trouble and you want the box without the extra ramp and mat.
• Choose the Ease S1 if you have a kitten, a senior cat or a large cat that struggles with a high entry, or you want less litter tracked onto the floor.
