Why facilities choose the PaintMaster Mini

The PaintMaster Mini is built for small to medium-sized sports clubs and community organizations that want professional autonomous line marking without the stadium-class footprint or budget. Compact, light, and battery-portable, with the same RTK accuracy the Pro uses on full-size fields.

Right-sized for schools and parks

Compact 25.83 × 25.78 × 17.83 in (656 × 655 × 453 mm) chassis at 48 lb (21.85 kg) lets one person carry, transport, and operate it without specialty equipment. Perfect for school athletic departments, parks crews, and youth sports clubs.

Industrial-grade RTK accuracy

Industrial-grade RTK delivers stable, interference-resistant centimeter-level signal. Supports both local base stations and FJD N10 CORS System with professional NTRIP services for flexible signal solutions across deployments.

Real cost and labor savings

Up to 90 percent labor reduction and 50 percent paint reduction versus a manual paint cart. Quick battery swap keeps the robot working all day, and one charge covers a full 11v11 standard football field.

Safe and theft-protected

Vision plus bumper protection for safer autonomous marking. Real-time GPS tracking with an independent anti-theft module that protects the robot for up to 1 month even when completely powered off.

Best fit buyers and environments

The PaintMaster Mini is strongest where its specific strengths line up with the way the property runs every week. Use the cards below to gut-check fit before requesting pricing.

Ideal buyers

School athletic directors, parks and recreation supervisors, youth sports club operators, community recreation managers, and small-to-mid sports club operations leads who want autonomous line marking without the stadium-class price or footprint.

Top deployment types

School athletic fields, public parks, community recreation centers, youth sports clubs, mid-sized sports clubs, and tennis courts. Compatible sports include soccer, rugby, lacrosse, baseball, and tennis.

When to choose something else

If you mark stadium-grade or full-size 11v11 fields at high paint volume, the PaintMaster Pro is the better fit thanks to 25 L paint capacity and the optional laser kit. If you want line marking as part of a multi-job platform that also mows, look at the RM21 with the LM01 line marker kit, or the Titan with the optional line marker kit.
