Loona Review: The Most Pet-Like Companion Robot, If You Can Forgive the Quirks

Loona is the robot in the ads that actually looks alive: a little wheeled creature that balances itself, zips across the floor, perks its ears, follows you with a camera and answers when you talk to it. It is the most pet-like of the companion robots, and at about $499.90 it is also the most expensive. Whether it is worth nearly twice an EMO comes down to how much you value movement, and how much patience you have for its quirks.

What it is

Loona is a mobile companion robot built on a four-wheel self-balancing drive, with autonomous navigation from a 3D time-of-flight sensor and a 720p RGB camera. It recognizes faces, gestures and voice, expresses itself through body and ear movement, and runs ChatGPT-4o for conversation with no subscription. When its battery runs low, after roughly two hours, it returns to its charging dock on its own. KEYi reinforced the servos and joints on the 2026 units to better survive energetic play (Origin of Bots; KEYi Tech).

What it gets right

The movement is the whole point, and it is the thing nothing else in this roundup does. EMO walks around a desk; Loona moves through a room, reacts to where you are, and behaves enough like a small pet to trigger that response in people. The ChatGPT-4o layer adds conversation on top, and the absence of a subscription is a real plus at this price. KEYi’s companion app is reasonably well rated, around 4.2 stars across 581 Google Play reviews, and owners frequently praise the after-sales service.

Where owners get frustrated

Loona’s reach exceeds its grasp in predictable places. The most common complaints, reflected across owner reviews including on Trustpilot, are about navigation: it can fail to find or reach its charger, and it needs a tidy, open room to roam well, with clutter and drop-offs causing trouble. Some owners also describe the interaction as inconsistent, with the robot falling back on generic animations that do not respond to the environment rather than reacting in context. And the motors are audible in a quiet space. None of these is a dealbreaker on its own, but together they are the gap between the perfect pet in the ad and the real thing on your floor.

The two-hour battery is the other hard limit. The auto-docking helps, but only as well as the navigation that gets it back to the dock, which is exactly the soft spot.

Against the alternatives

Against EMO ($279), Loona wins decisively on movement and loses on price and, arguably, on how reliably it does the clever things it attempts. Against Eilik ($139.99), it is a different class of device entirely: Eilik is a charming offline toy, Loona is an ambitious mobile petbot at three to four times the cost. Against Casio Moflin ($429), Loona is the active, mobile, interactive option where Moflin is the quiet comfort object; they appeal to opposite moods.

Verdict

Our synthesis score is 7.0. The concept and the movement are best-in-class, and the no-subscription ChatGPT-4o and decent app and support keep it credible. The score is held back by the price, the short battery, the audible motors, and most of all the navigation and interaction inconsistencies that turn up repeatedly in owner reports. Buy Loona if a robot that moves through your space like a pet is what you are paying for and you will forgive its rough edges. If you want reliability or value over spectacle, EMO and Eilik are the safer money.
