The Echo Robotics TM-850 (Model TM-850) bridges the gap between the brand's larger commercial mowers and smaller residential-grade robots, combining the GPS-RTK technology platform of the TM-1050 and TM-2050 into a lighter, more compact form factor purpose-built for professional sports turf and managed green space applications. At just 25 kg it exerts minimal pressure on even the softest playing surfaces, eliminating the compaction concerns associated with heavier ride-on maintenance equipment while still covering up to 30,000 m² (7.4 acres) per week. Two oscillating floating cutting heads with stainless steel blades adapt continuously to terrain undulations, delivering a consistent, professional-quality mulch cut across the full 16.5" strip width on every pass — without scalping, without missed patches, and without operator involvement.

Guided by GPS-RTK Wisenav technology with centimeter-level accuracy, the TM-850 maps and works its designated zones in precise, systematic lanes rather than random patterns, optimizing coverage efficiency and leaving a clean, striped finish that reflects the professionalism of the facility it's maintaining. No-go zones, cutting heights, schedules, and multi-zone configurations are all managed remotely through the Echo smartphone app or web portal, with Wi-Fi and 4G connectivity keeping the machine accessible from anywhere at any time. The durable aluminum chassis is designed for long-term commercial use in demanding outdoor environments, and the removable cover simplifies cleaning between sessions. When the battery runs low, the TM-850 autonomously returns to its charging station and resumes exactly where it left off — keeping mowing cycles continuous and uninterrupted without any human coordination required.

• Wire-Free GPS-RTK Navigation — Wisenav technology delivers centimeter-level accuracy across up to 7.4 acres without boundary wire installation, with no-go zones and work zones managed entirely from the smartphone app
• Two Oscillating Floating Cutting Heads — independently adapt to terrain contours in real time, ensuring a consistent, professional mulch cut across uneven or irregular playing surfaces without scalping
• 24/7 Autonomous Operation with Auto-Return Charging — operates continuously day and night, automatically returning to its charging station when needed and resuming exactly where it left off with no manual intervention required
