Big coverage, wire-free, without the big-mower price.
The Segway Navimow X3 Series covers more ground per dollar than anything else we carry - from half an acre up to 2.5 acres, all without a boundary wire. EFLS 3.0 navigation fuses RTK satellite positioning with VSLAM and visual odometry, so it keeps its place even when the sky view isn't perfect, and VisionFence 2.0 cameras handle obstacles.
Set it up once. Then stop thinking about the lawn.
Who the Navimow X3 Is Built For
This mower is the right fit if:
- Your mowing area is 0.5 to 2.5 acres, depending on model
- Your yard is flat to moderately sloped - up to a 50% grade (27°)
- You want maximum acreage coverage for the money
- You want wire-free RTK navigation with camera-based obstacle avoidance
- You'd rather buy from an authorized dealer than gamble on a marketplace warranty
Got real hills? The X3 is rear-wheel drive. If your yard has steep grades, step up to the Navimow X4 series - 4WD with all-wheel steering, rated to 84% (40°) - or a Mammotion LUBA 3 AWD at 80%. Not sure? Use the mower selector.
What Makes the X3 Different
Coverage That Scales With Your Property
Four models share the same technology and differ only in battery and runtime, so you buy exactly the capacity your lawn needs - from the X315 at half an acre to the X390 at 2.5 acres with four hours of runtime per charge.
EFLS 3.0 - Navigation That Doesn't Rely on Satellites Alone
Most wire-free mowers are pure RTK, which struggles near trees and buildings. EFLS 3.0 fuses RTK with VSLAM (visual mapping) and VIO (visual inertial odometry), so the X3 keeps tracking its position when satellite reception weakens.
VisionFence 2.0 Obstacle Avoidance
AI-powered RGB and Time-of-Flight cameras detect edges, pathways, and obstacles, and stop for people, pets, and toys. No boundary wire to bury, no perimeter cable to install.
Traction Control on 10-Inch Wheels
A traction control system meters power to the X3's 10-inch wheels, holding grip on damp grass and moderate grades where smaller-wheeled mowers slip.
Quiet Enough for Any Schedule
At 60 dB(A) the X3 can run early, late, or overnight without bothering your household or the neighbors. Smart zones, scheduling, and 4G control are all handled in the app - including Doodle Mode, which cuts custom patterns or designs into your lawn.

Why Buy Your Navimow X3 From Midwest Turf Tech?
A product page can tell you what a mower does. What it can't tell you is what happens after the box shows up.
Authorized Segway Navimow dealer. Your warranty is real. If you need a part, a repair authorization, or manufacturer support, buying from an authorized dealer keeps those paths open. Gray-market listings often close them off quietly.
Real setup support. Questions about RTK placement, zone mapping, dock location, or app configuration? We work with these machines every day. We can help.
Nationwide shipping. We ship the Navimow X3 to all 48 contiguous states. Financing is available through Shop Pay and Affirm.
Local install available. In the Twin Cities metro? Professional installation and lawn mapping is available - worth it on acreage, where dock placement and zone setup make a real difference. Not local? Remote setup support gets you running faster.
Not sure the X3 is the right fit for your yard? Use the mower selection tool or reach out before you buy. We'd rather help you pick the right mower than sell you the wrong one.
Navimow X3 - Frequently Asked Questions
What is the difference between the X315, X330, X350, and X390?
Coverage and runtime. All four share the same EFLS 3.0 navigation, VisionFence 2.0 cameras, drive system, and cutting deck. The X315 covers 0.5 acre (6 Ah, 120 min), the X330 covers 1 acre (8 Ah, 160 min), the X350 covers 1.5 acres (10 Ah, 200 min), and the X390 covers 2.5 acres (12.8 Ah, 240 min). Choose by lawn size.
How steep a slope can the Navimow X3 handle?
Up to a 50% grade, which is about 27 degrees. The X3 is rear-wheel drive with a traction control system. If your yard has steeper hills, the all-wheel-drive Navimow X4 series (84% / 40°) or Mammotion LUBA 3 AWD (80%) is the better choice - two-wheel-drive mowers lose traction on wet grass well before their rated limit.
Is the Navimow X3 all-wheel drive?
No. The X3 is rear-wheel drive with a traction control system and 10-inch wheels, which handles flat to moderately sloped lawns well. The Navimow X4 series is the all-wheel-drive model, built for steep and rough terrain.
Does it need a boundary wire?
No. The X3 is fully wire-free. EFLS 3.0 combines RTK satellite positioning with visual mapping to establish its own boundaries - there is no buried cable or perimeter wire to install.
Will it work under trees?
Better than satellite-only mowers. EFLS 3.0 adds VSLAM and visual inertial odometry to RTK, so the X3 keeps tracking position when tree canopy weakens satellite reception. For heavily wooded properties, a LiDAR-based mower like the Mammotion LUBA 3 is still the stronger choice.
How loud is it?
60 dB(A) - quiet enough to run during the day or on a night schedule without disturbing your household or neighbors.
Is Midwest Turf Tech an authorized Segway Navimow dealer?
Yes. Midwest Turf Tech is an authorized Segway Navimow dealer. Your warranty is valid and you have direct access to authorized parts, service, and support - not available through gray-market or unauthorized listings.
