ZHMZ G1 Self-Cleaning Litter Box with App Control and Sealed Waste Drawer

For a home where you want litter waste separated automatically after your cat leaves, the ZHMZ G1 offers a hands-off alternative to a standard litter box. Its drawer collects waste, while a mat is included to catch tracked litter. The app adds remote control, but the unit can also be used without it. Is that mix of automation and manual control a fit for your routine?

At a glance

The G1 is a gray, ABS self-cleaning litter box measuring 21 x 19 x 26 inches and weighing 33 pounds. It has a 12-inch opening and is designed for cats weighing 2.5 to 18 pounds, with a length under 18 inches and height under 15 inches. Those size limits matter: a cat that falls outside them may not be suited to this unit.

After a cat leaves, the box separates waste into a drawer. The waste drawer is described as sealed to help minimize odors, and the included litter mat catches litter carried outside. Dual sensors, four weight sensors, and remote alerts are intended to pause cleaning when a cat enters. The app supports 2.4GHz Wi-Fi, automatic and manual modes, and behavior and health monitoring. Manual cleaning requires enabling “kitten mode.”

The package includes the G1, four support legs, two rolls of litter bags, a litter mat, an adapter, and a user manual. It’s a great fit if you want automated waste collection and app controls in one unit, rather than a basic box that relies on manual scooping.

Cleaning & care

Litter choice and sensor upkeep affect how the unit operates. The instructions recommend easy-clumping, low-dust litter, dusty litter can obscure the sensors. Mineral litter is given as an example. The default clumping delay is three minutes after the cat leaves, and the delay can be adjusted in the app.

After adding litter, hold the Clean button to reset the weight reading before starting a cycle. The manufacturer’s troubleshooting instructions say a successful reset displays “A.” If the unit stops with the trash-can indicator lit, dust around the waste-bin sensors may be the cause, the guidance is to remove the top cover and drum compartment, wipe the four sensor points, then reinstall the parts. Check that the drum clips are secure before running it.

Practical tips

Set the box on a level, firm surface, the instructions specifically warn against uneven carpets or rugs. Leave access to the waste drawer for disposal and keep the included bags handy. If you prefer not to use a phone app, the box still works without downloading one, app control is an added option, not a requirement.

The automatic cycle and waste drawer suit households looking to reduce routine scooping, while a simpler litter box may be easier to manage if you prefer a fully manual setup. The G1’s extra sensors also mean keeping their points clean is part of routine care. Its listed weight and dimensions are useful to consider when deciding where it will sit.

Final verdict

The ZHMZ G1 is worth considering if its stated cat-size limits match your pet and you want automatic waste separation, a sealed drawer, and optional app control. It’s not for you if your cat is too tall or heavy for the listed requirements, or if you cannot place the unit on an even surface. For households within those constraints, the included mat and litter bags make the setup more complete, though the low-dust litter guidance and sensor cleaning are practical parts of ownership.
