Segway Navimow X390 Robotic Lawn Mower – Up to 2.5 Acres | Wire-Free, AI Vision, EFLS 3.0

Premium Autonomous Lawn Care for Large Residential Properties

The Segway Navimow X390 is a premium wire-free robotic lawn mower designed for large residential properties up to 2.5 acres.

Built for homeowners who want to eliminate hours of routine mowing without stepping all the way up to a commercial platform, the X390 combines EFLS™ 3.0 precision positioning, AI-assisted mapping, advanced obstacle detection, automatic charging and resume, and quiet autonomous operation in one intelligent mower.

With up to 240 minutes of mowing time per charge, a 50% slope capability, and the ability to recognize hundreds of common yard obstacles, the X390 is built for large, complex lawns that demand more than an entry-level robotic mower.

At a Glance

Built for Lawns Up to 2.5 Acres

The X390 is the largest-capacity mower in Navimow’s X3 residential series.

For homeowners with large estates, acreage properties, oversized yards, or multiple connected lawn areas, it provides an alternative to spending hours every week on a riding mower.

Instead of waiting for the grass to grow and cutting everything at once, the X390 can mow frequently throughout the week, recharge automatically, and resume its schedule without requiring an operator.

The result is a lawn that stays consistently maintained rather than periodically “caught up.”

No Perimeter Wire

The X390 uses virtual boundaries instead of buried perimeter wire.

That means:

• No trenching

• No broken boundary wire

• No accidental wire cuts

• Easier lawn modifications

• Cleaner installation

The mower creates its working areas digitally through the Navimow system, making it much easier to adapt the lawn map as landscaping changes.

EFLS™ 3.0 Precision Navigation

The X390 uses Navimow’s EFLS™ 3.0 positioning system, which combines enhanced RTK coverage with visual positioning technologies such as VSLAM and VIO.

The goal is improved accuracy and stability in challenging residential environments, including:

• Front and back yards

• Narrow passages

• Tree-lined areas

• Areas near structures

• Complex lawn shapes

This multi-layer positioning approach helps the mower stay on course even where satellite reception may be less than ideal.

AI-Assisted Automatic Mapping

Setting up a large robotic mower should not require hours of manual driving.

The X390 supports AI-assisted mapping, allowing it to automatically identify and map lawn areas rather than forcing the user to manually trace every boundary.

Navimow also uses positioning and signal analysis to help recommend the best locations for the charging station and antenna.

For a large property, that can significantly reduce setup time.

Dual-Base Station Support for Difficult Properties

Large or complex properties sometimes include areas where RTK reception is weak.

The X3 platform supports the use of a second antenna/base station to expand signal coverage and improve stability in difficult environments.

This can be especially useful for:

• Large front-and-back-yard layouts

• Properties with heavy tree cover

• Buildings blocking line-of-sight

• Narrow side yards

• Complex estate properties

The second antenna is sold separately.

50% Slope Capability

The X390 can handle slopes up to 50% or approximately 27°.

Navimow combines this climbing ability with its proprietary Traction Control System (TCS) to help manage wheel slip and maintain stability on demanding terrain.

The design also incorporates:

• 10-inch wheels

• Rear-biased weight distribution

• Intelligent traction management

For large properties with rolling or hilly terrain, this is a major advantage over many basic residential robot mowers.

Advanced Obstacle Detection

The X390 uses a 300° RGB + ToF sensing system to identify objects around the mower.

Navimow states that the X3 platform can recognize more than 200 common yard objects, including:

• Pets

• Lawn furniture

• Toys

• Fixed obstacles

• Suspended items

• Landscaping features

This helps the mower navigate safely around the kinds of objects normally found on an active residential property.

Safer Around Pets, Wildlife and Family

One of the major benefits of advanced vision-based mowing is improved situational awareness.

The X390 is designed to recognize and avoid objects rather than simply relying on physical contact.

That makes it especially attractive for properties with:

• Dogs

• Children

• Outdoor furniture

• Play equipment

• Landscaping

• Decorative features

• Wildlife

No robotic mower replaces normal safety precautions, but better environmental awareness can substantially improve day-to-day operation.

Up to 240 Minutes of Mowing Per Charge

The X390 offers up to 240 minutes of mowing time on a full charge.

When the battery runs low, it can:

1. Return to the charging station

2. Recharge automatically

3. Resume the mowing schedule

Navimow lists a full recharge time of approximately 100 minutes.

For a 2.5-acre mower, that combination of long runtime and automatic recharge is important because the machine is designed to maintain the lawn continuously rather than complete the entire property in one uninterrupted pass.

9.3-Inch Cutting Width

The X390 uses a 9.3-inch cutting system designed for frequent autonomous mowing.

The narrower deck helps the mower maneuver through complex residential properties while still maintaining large areas efficiently through repeated scheduled operation.

Adjustable 2–4 Inch Cutting Height

The X390 provides an adjustable cutting range from approximately 2 inches to 4 inches.

That makes it suitable for many common residential turf varieties and allows the mower to be configured around:

• Grass type

• Seasonal conditions

• Desired lawn appearance

• Property-specific mowing preferences

Ultra-Quiet 60 dB(A) Operation

Traditional gas-powered lawn equipment can disrupt neighbors, family, guests, or outdoor activities.

The X390 operates at approximately 60 dB(A) in standard mode.

That makes it quiet enough to mow during times when a conventional mower would be disruptive.

For large residential properties, this is one of the biggest lifestyle advantages of robotic mowing.

Smart Home Integration

The X390 supports both:

• Amazon Alexa

• Google Home

Owners can use voice commands for basic mowing functions such as starting, stopping, or scheduling mowing tasks.

That gives the X390 another advantage for homeowners already using connected smart-home technology.

Security & GPS Tracking

The X390 includes multiple security features designed to help protect the mower.

Features include:

• GPS tracking

• Lift alerts

• Outside-boundary alarms

• App monitoring

• Hidden compartments for additional tracking devices

For a high-value mower operating autonomously outdoors, these are important ownership features.

IP66 Weather Protection

The X390 carries an IP66 protection rating, helping protect the mower against dust and strong water exposure.

That makes it suitable for outdoor operation in changing weather conditions.

As with any robotic mower, proper charging-station placement and seasonal storage practices are still recommended.

Optional Edge Trimmer Accessory

Navimow also offers a compatible Trimmer accessory designed to provide semi-automatic edge trimming.

This accessory can reduce the amount of manual string trimming required along lawn edges and help create a more complete autonomous lawn-care system.

For homeowners trying to eliminate as much repetitive yard work as possible, this is a particularly interesting upgrade.
