I get asked about ball machines constantly, usually right after a lesson, when a player realizes the thing holding their forehand back is simply reps. You can’t groove a stroke twice a month. So I’ve spent the last six months coaching with the Tennibot Partner, hitting with it two or three times a week, and put it through the kind of practice I actually prescribe. Here’s the honest version.
Full disclosure: I bought and use the Partner myself, and I know the Tennibot team. Nobody paid for this review. It’s my genuine opinion as a coach, warts and all.
What the Tennibot Partner actually is
The Partner is an AI-powered, app-controlled ball machine. Tennibot calls the current model “the most advanced AI ball machine yet,” and after six months I get why the “AI” part matters: instead of firing the same ball to the same spot, it varies placement, pace, and spin so the feed is less predictable and closer to a real opponent. That unpredictability is the whole game for practice quality.
You run it from your phone. You pick the court, build a drill, and it’s ready in under a minute. The current version is also lighter and smaller than the last one, with a higher lob, and it works on hard, clay, grass, and turf. It’s built for tennis, and it also handles pickleball and padel.
One thing to be clear about, because people mix this up: the Partner feeds balls, it doesn’t collect them. Ball pickup is a separate Tennibot product (the Rover). Judge the Partner on the practice it gives you, not on cleanup.
Where it shines for forehand work
This is where I care most. For the players I coach, the Partner is genuinely useful because I can build the exact rep pattern I’d want:
- Crosscourt forehand grooving. Clean, repeatable reps to lock in the swing path I’m teaching.
- Recovery under load. Program a wide forehand, then a ball back to the middle, and now you’re practicing the movement around the stroke, not just the stroke. A standard machine can’t do that.
- Depth and spin variety. Mixing a heavy topspin ball with a flatter, faster one forces you to adjust your contact point, which is exactly what breaks down in matches.
The consistency plus the variety is the real value. When I fix a forehand, the change only sticks with volume, and this delivers volume that doesn’t get boring or predictable.
What I’d flag before you buy
No machine is perfect, and an honest review says so:
- It’s a premium machine, not a budget one. If you want the cheapest feeder, this isn’t it (see my ball machine guide).
- Like every ball machine, it feeds but doesn’t pick up. Budget for a hopper or the Rover if collection is your pain point.
- The app-driven approach has a small learning curve. Give it a session or two.
Tennibot Partner vs. a standard ball machine
A basic machine is a metronome: same ball, same spot, fixed oscillation. Fine for a warmup, limited for real improvement. The Partner’s edge is app-controlled, AI-varied drills that move you around the court — practice that looks like a point instead of a drill line. That’s the difference between grooving a stroke and actually preparing for a match.
Who I’d recommend it to
- Players without a reliable hitting partner who still want match-like reps.
- Anyone drilling a specific fix who needs volume with variety.
- Improvers and juniors who progress fastest on repetition.
My verdict: 4.5 / 5
A ball machine doesn’t replace coaching, it multiplies it. The Tennibot Partner earns its place because the app turns a lesson into a repeatable, match-like practice plan a player can run alone. At $2,245 it’s a premium buy, not an impulse one, but if you’re serious about your forehand and you practice on your own, it’s the most useful machine I’ve put my students in front of.
