Segway Navimow Terranox CM120M1 Commercial Robotic Lawn Mower – Up to 3 Acres | AWD, Wire-Free

Commercial-Grade Autonomous Mowing for Properties Up to 3 Acres

The Segway Navimow Terranox CM120M1 is a professional autonomous robotic lawn mower designed to maintain up to 3 acres of turf with minimal manual mowing labor.

Built for commercial properties, large residential estates, sports facilities, golf courses, parks, campuses, municipalities, schools and other large green spaces, the CM120M1 combines all-wheel drive, Network RTK positioning, 360° vision, automatic mapping and intelligent obstacle avoidance in a professional wire-free robotic mowing platform.

Unlike traditional robotic lawn mowers that rely on buried perimeter wires, Terranox uses digitally mapped virtual boundaries. Where Network RTK (NRTK) coverage is available, no local RTK antenna is required either.

For property owners and facility managers looking to automate approximately 1–3 acres of mowing, the CM120M1 brings Segway Navimow's commercial Terranox technology to a more compact large-acreage platform.

At a Glance

*Maximum-area mowing time includes charging and is based on Navimow testing conditions. Actual mowing capacity and operating time can vary according to terrain, slope, obstacles, lawn shape, cutting height, grass conditions and other environmental factors.

A Professional Robotic Lawn Mower for Up to 3 Acres

The Terranox CM120M1 is built for acreage.

Navimow rates the CM120M1 to maintain up to 3 acres within approximately 40 hours, including its autonomous mowing and charging cycles.

With a mowing speed of up to 2 mph, a 17-inch cutting width and up to 145 minutes of runtime, the CM120M1 can continually maintain large areas without requiring an operator to sit on a mower.

That makes it an excellent robotic mowing solution for:

• Large residential properties and estates

• Corporate campuses

• Commercial properties

• Sports fields and athletic facilities

• Golf courses

• Parks and municipal properties

• Schools and universities

• HOAs and community common areas

• Resorts and hospitality properties

• Churches and institutional campuses

An Excellent Robotic Mower for Large Residential Properties

Although Segway Navimow developed Terranox as its professional mowing platform, the CM120M1 can also be an outstanding solution for homeowners with 1–3 acres of mowable turf.

This is an important distinction.

Owners of large residential properties have traditionally had limited options:

Buy a riding mower.

Spend hours mowing every week.

Or hire a lawn service to mow the property repeatedly throughout the season.

The CM120M1 provides another option: automate the mowing.

Once the property is properly mapped and configured, Terranox can continually maintain the lawn—leaving the homeowner to focus on everything except routine mowing.

For estates, acreage homes and other premium residential properties, the CM120M1 provides commercial-grade technology in an autonomous mower sized specifically for properties up to approximately 3 acres.

No Boundary Wire

Forget burying hundreds or thousands of feet of perimeter wire.

The Terranox CM120M1 uses virtual boundaries instead of a physical boundary wire.

The property and individual mowing areas are digitally mapped through the Navimow system.

That provides several advantages.

There is no perimeter wire to break.

There is no wire to accidentally cut during landscaping.

There is no need to dig up and relocate wire when landscaping changes.

And modifying mowing zones can be considerably easier than with traditional wire-guided robotic mower systems.

For large properties, eliminating perimeter wire can make robotic mower installation significantly more practical.

Network RTK – No Local Antenna Required Where Available

Terranox uses Navimow's EFLS™ NRTK positioning system.

The system combines:

• Network RTK positioning

• 360° visual positioning

• Visual Inertial Odometry (VIO)

Where Network RTK service is available, the CM120M1 can operate without installing a local RTK antenna on the property.

If Network RTK coverage isn't available at the installation location, Terranox can switch to a local RTK solution.

Automation Hub can help evaluate your property and determine the appropriate positioning configuration before installation.

Intelligent Automatic Mapping

One of the challenges of deploying robotic mowers across several acres is creating the initial property map.

Terranox is designed to simplify that process through intelligent mapping technology.

Virtual boundaries allow individual mowing areas, restricted areas and routes between working zones to be established digitally rather than through physical perimeter wiring.

For commercial properties and large residential estates, this provides substantially more flexibility as the property evolves.

AWD for Hills and Difficult Terrain

Large properties rarely consist of perfectly flat, rectangular lawns.

The CM120M1 features a true all-wheel-drive system capable of handling slopes up to 40° or 84%.

AWD provides additional traction and control across:

• Steep hills

• Rolling terrain

• Uneven lawns

• Large residential properties

• Commercial landscapes

• Golf and sports turf

• Complex mowing areas

This makes Terranox especially attractive for properties where terrain would challenge smaller conventional robotic lawn mowers.

360° VisionFence™ Obstacle Detection

The CM120M1 doesn't navigate using satellite positioning alone.

Navimow's VisionFence™ system combines 360° RGB cameras with Time-of-Flight (ToF) sensing to provide environmental awareness around the mower.

The system helps Terranox identify and navigate around objects encountered while mowing.

For a professional robotic mower operating autonomously across several acres, this additional environmental awareness is particularly important.

EFLS™ NRTK Precision Navigation

Large-acreage robotic mowing requires reliable positioning.

Terranox combines:

Network RTK + 360° Vision + Visual Inertial Odometry

Navimow describes its system as capable of centimeter-level positioning accuracy while maintaining stable navigation through complex environments.

Instead of depending on a single positioning technology, Terranox combines satellite and visual information to understand where the mower is operating.

17-Inch Professional Cutting Width

The CM120M1 provides a 17-inch cutting width, allowing it to efficiently cover large mowing areas while remaining maneuverable around landscaping and other property features.

Its commercial cutting system is designed for frequent autonomous mowing rather than the traditional approach of allowing grass to grow significantly between cuts.

The mower continually maintains the turf over its scheduled operating cycle.

Adjustable 0.75–4 Inch Cutting Height

The CM120M1 offers an approximately 0.75-inch to 4-inch cutting-height range.

That unusually broad range makes Terranox useful across many turf applications.

Potential applications include:

• Residential lawns

• Commercial turf

• Parks

• Sports facilities

• Campuses

• Selected golf-course areas

• Institutional properties

The appropriate cutting height will depend on turf variety, application and desired finish.

Up to 145 Minutes of Runtime

The CM120M1 provides up to 145 minutes of mowing runtime.

But runtime alone doesn't tell the complete story with an autonomous mower.

Terranox is designed to work in cycles.

It mows.

It returns to charge.

It resumes mowing.

And it continues maintaining the property according to its schedule.

This is why Navimow rates the CM120M1 based on the amount of property it can maintain over time rather than simply how long the battery lasts during one mowing session.

Up to 3 Acres Within 40 Hours

Navimow rates the CM120M1 to maintain up to 3 acres within approximately 40 hours, including charging time under its testing conditions.

That's fundamentally different from traditional mowing.

The objective isn't necessarily to mow the entire property during one afternoon.

Instead, Terranox continuously maintains sections of the property so the grass stays at the desired height.

For many properties, that can produce a more consistently maintained appearance than periodic conventional mowing.

NavimowFleet™ Remote Management

Professional Terranox installations can be managed through NavimowFleet™, Navimow's commercial fleet-management platform.

The platform is accessible through an app and web portal and is designed to help operators remotely manage robotic mowing operations.

For customers deploying multiple Terranox mowers, centralized management becomes particularly valuable.

Instead of individually supervising machines throughout a large property or across multiple locations, operators can manage their autonomous mowing fleet through one system.

Reduce Repetitive Mowing Labor

One of the biggest advantages of autonomous mowing is simple:

The robot doesn't need someone sitting on it.

Traditional mowing ties together two valuable resources—a machine and an employee—for the entire mowing process.

Terranox separates the two.

Once properly installed and configured, the robot can perform repetitive mowing autonomously.

That can allow employees and landscaping crews to focus on higher-value work such as:

• Landscaping

• Trimming

• Edging

• Irrigation

• Course maintenance

• Sports-field preparation

• Plant health

• Property improvements

• Other detailed grounds work

For homeowners, it simply means getting back the hours normally spent on a riding mower.

Commercial Applications

Golf Courses

Terranox can autonomously maintain suitable golf-course turf while allowing maintenance personnel to concentrate on higher-value course work.

Sports Fields & Athletic Facilities

The CM120M1 can continually maintain suitable turf areas without dedicating an operator to routine mowing.

Corporate Campuses

Maintain professional grounds while reducing repetitive mowing labor and noise around occupied facilities.

Municipalities & Parks

Large Residential Estates

For homeowners maintaining approximately 1–3 acres, the CM120M1 can replace hours of repetitive riding-mower work with continuous autonomous lawn maintenance.

CM120M1 vs. CM240M1 – Which Terranox Do I Need?

Segway Navimow currently offers two Terranox models for large-area mowing.

For properties comfortably below 3 acres of mowable turf, the CM120M1 will generally be the starting point.

For larger properties, heavier workloads or applications approaching 3–6 acres, consider stepping up to the CM240M1.

Automation Hub can help evaluate the actual mowable acreage and property complexity before recommending either model.

Is the Terranox CM120M1 Right for My Property?

The CM120M1 should be on your shortlist if:

• You have up to approximately 3 acres of mowable turf

• You want to eliminate or reduce weekly mowing

• You have hills or challenging terrain

• You don't want buried boundary wire

• You want an AWD robotic mower

• You need commercial-grade autonomous mowing

• You own a large residential property

• You manage a commercial campus

• You operate a sports facility
