FAQs

Technology & Terminology

Explaining the engineering behind the performance.

What is the "28-Point Custom Drill" feature?

Found in our flagship models (like the JT-S6), this technology allows players to program 7 different horizontal lines across the court, with 4 distinct depth settings for each. This creates a matrix of 28 landing points that can be sequenced to simulate real-match scenarios.

What is "Internal Oscillation" and why does it matter?

Unlike traditional machines that pivot the entire body (making it easy for opponents to telegraph the shot), J-BOT uses internal oscillation. The outer shell remains stationary while the firing mechanism moves inside. This hides the direction of the ball, forcing you to improve your footwork and reaction time.

How does the spin control work?

J-BOT machines utilize a dual-motor counter-rotating wheel system. By adjusting the speed differential between the top and bottom wheels, you can generate heavy Topspin (dip and kick) or aggressive Backspin (slice/underspin) across multiple intensity levels.

App, Connectivity & Intelligence

Seamlessly integrating tech into your training.

How do I connect the J-BOT App to my machine?

Power on your J-BOT machine.
Enable Bluetooth on your smartphone (Android users must also enable Location Services).
Open the "Jbotsports Pro" App. The app will automatically scan and pair with the machine's signal. No manual pairing in your phone's Bluetooth settings is required.

What should I do if the App fails to connect?

Ensure no other smartphone is currently connected to the machine (J-BOT supports one active connection at a time). Check that your machine’s battery is above 20%. If issues persist, restart the machine and force-close the app.

Are there pre-programmed training modes?

Yes. Our App features a "Training Camp" library designed by professional coaches. These include "Cross-court Drills," "Inside-out Forehand," and "High Lob" sequences that can be activated with a single tap.

Hardware, Battery & Performance

Detailed specs for the serious athlete.

What is the battery life and charging protocol?

Runtime: The 24V 10AH High-Capacity Lithium battery provides 4 to 8 hours of continuous play depending on speed and oscillation settings.Charging: Use only the provided 24V 2A smart charger. A full charge takes approximately 5–6 hours. The charger supports global voltages (AC110-240V).

What type of tennis balls should I use?

J-BOT is compatible with standard pressurized balls, pressureless balls, and Tretorn/low-compression balls. Important: Avoid using wet or extremely dirty balls, as they can cause slippage on the firing wheels and reduce accuracy.

Is the machine portable?

Absolutely. Our S and L series feature oversized "all-terrain" wheels and a telescopic trolley handle, making it easy to transport across grass, gravel, or court surfaces.

Maintenance & Troubleshooting

Keeping your J-BOT in peak condition.

The machine is beeping and won't fire. What's wrong?

This is usually a safety self-check alert. Ensure the "Firing Mouth" is clear of any balls or debris during startup. Turn the power off, clear any obstructions, and restart.

How do I clean the serving wheels?

Over time, felt from tennis balls can build up on the wheels. With the power OFF, use a damp cloth or a fine-grit sandpaper to gently remove the residue from the surface of the wheels to maintain consistent grip and spin.

The "REST" button popped out. What happened?

This is the Overload Protection circuit breaker. It trips if a ball is jammed or the motor is overheated. Clear the jam, wait 2 minutes, and press the REST button back in to resume play.

Shipping, Warranty & Support

What is the J-BOT Warranty Policy?

We offer a 2-year limited warranty on the main machine components and a 6-month warranty on the battery.
