Tennis Ball Machines Compared: Which One Fits You?

Ball machines have been around for decades – and most of them still work exactly the way they did back then: they throw balls, nothing more. They don't see you, they don't adapt, and you carry them around like a bag of cement.

We looked at the machines you can actually buy today and laid them out plainly: How heavy are they? What can they do with spin? Do they track you and the ball? How many structured drills do you get? Is there an app – and what does it all cost?

One thing up front, in fairness: Slinger, Spinshot and Lobster are solid, established machines. They do their job. But they come from an era before the camera. Tenniix is the world's first vision-based AI tennis robot – that's a different class, not a better model of the same kind. And that's exactly what the comparison makes visible.

A note on fairness: All competitor data comes from publicly available manufacturer and retailer information (as of June 2026). Prices and weights vary by model variant and bundle – we give ranges where they exist and link the sources. Spotted something out of date? Tell us and we'll fix it.
