It suits families with kids who want a robot that roams the floor, plays games and teaches basic coding. Skip it if you want long play sessions, since it needs its dock after an hour or two, or if a camera robot roaming your home worries you.

Bittle X V2 is a strong pick for kids 10 and up, students and hobbyists who want to learn coding and robotics on a real legged robot that runs offline. Skip it if you want a hands off pet for cuddling or long play, since it walks about an hour per charge and the best experience involves some programming.

What reviewers found
KEYi Tech Loona Petbot Premium
- TechCrunch: Praised the clever, durable design and charm, but voice commands worked about half the time, vision recognition was unreliable and it sometimes got stuck on furniture. Fun for kids but rough around the edges. Source
- Mashable: Hands on at CES 2025: Loona roamed the floor, played fetch, answered a question conversationally and generated a simple picture on request. The reviewer wanted more detail on data handling before using it with children. Source
Petoi Bittle X V2
- Make:: Tested the Bittle X V2 with arm alongside the Nybble Q; noted built in voice control and an ESP32 board, that you never have to assemble circuit boards, and that Bittle is the more durable choice, though neither is a foolproof consumer product. Source
- Movies Games and Tech: Pre built Bittle X ran about an hour per charge; 35+ voice commands were new for this edition; setup needs software on a computer and the box has no printed instructions. Source
- Hinton Magazine: Praised the DIY kit as a way to learn robotics and wiring, the durable interlocking parts, OpenCat programming and 35+ voice commands. Source
