If you want actual rallies
Start with Acemate S10
It is the only core pick here built around catching and returning your incoming shot. That is a different job from even the smartest feeder.

If you want lighter + smarter
Start with Partner Lite or Proton
Tennibot Lite leads on capacity and warranty. Proton is eight pounds lighter and exceptionally easy to move, but direct shipping is currently US-only.
Use the finderIf you train at advanced pace
Spinshot owns the headline speed
The Player HS reaches a quoted 80 mph and carries 12 customizable drills. Its 41 lb body makes portability the compromise.
If you want a moving platform
Partner V2 is the premium system
It brings 4K cameras, 3D tracking, a moving drive base, a long battery and 140-ball capacity into one machine.

Carry weight
17 lb changes how often you train
If court access includes stairs or a long walk, Proton’s portability may beat every extra feature on paper.
Court realism
Movement costs money—and weight
Acemate and Partner V2 are more dynamic, but neither is the easiest machine to carry from a distant parking lot.
