Ninestars DZT-50-9 automatic trash can review

A 13.2-gallon stainless sensor can on three C cells, rated by Ninestars at roughly 10,000 open-close cycles, with a manual mode that holds the lid open. It suits someone who wants a sensor can and is irritated by consumables.

Two of its features are things more expensive cans do not offer, which is unusual enough to be the reason this review exists. It ranks third in our touchless roundup and it would rank higher if the sensor were adaptive.

That battery figure is the only one of its kind we found in this category. simplehuman, iTouchless, Kohler and EKO all decline to publish one. Whether Ninestars' number is conservative or optimistic we cannot say — it is their figure, not an independent test — but publishing it at all is a meaningful difference in a category this opaque.

Ten thousand cycles on three C cells

Run the arithmetic: at twenty opens a day, 10,000 cycles is about 500 days. A household of four opening it thirty times a day still clears a year. Three C cells is a modest, cheap set to replace, and Ninestars specifically credits an infrared design that preserves battery life rather than a bigger battery. How to work out your own figure.

A manual mode that holds the lid open

This is the feature we would most like every fixed-timer can to have. Press the button and the lid stays up until you press it again. It does not solve the two-second pause while you scrape a plate — only an adaptive sensor does that — but it completely solves the other half of the complaint: emptying a refrigerator, clearing a counter, or anything where you need the can open for a minute. On a can at this price, that is a genuinely thoughtful inclusion.

The removable ring liner is the third quiet win. It holds the bag by the rim rather than relying on friction, which is the cheapest effective answer to a bag sliding down the inside. Why bags slide.

The sensor is a fixed timer. The lid will close on your hand if you pause, and there is no setting for it. The manual mode covers the long jobs but not the everyday two-second pause, which is the complaint that actually drives returns in this category. If that specific behavior is what bothers you, only an adaptive sensor fixes it.

No mains option is published. iTouchless sells an AC adapter for its cans; Ninestars does not document one. So the good battery figure is the best you get rather than something you can sidestep entirely, and the can will still pass through a weak-emitter phase at the end of each battery cycle.

No odor filter in the lid. iTouchless builds one in as standard at a similar price. You can add a pod or a sachet under the lid yourself, but there is no purpose-made filter slot.

Twelve and a half pounds is heavy for a kitchen can. Good in that it stays put and does not get knocked over; less good when you want to move it to mop, and noticeably less good if the can has to go up or down stairs to be emptied.

The iTouchless 13 Gallon SensorCan trades the published battery figure for a built-in carbon filter and an AC adapter option — a reasonable swap if odor is your issue or there is an outlet nearby. The EKO Mirage-T is the plainest can in this tier: standard bags, a brushed finish, and nothing else, which for some kitchens is exactly right.
