The Segway Navimow X4 Series: A Real Leap Forward in Robotic Mowing

Most robotic mowers cut grass. The new Navimow X4 Series goes further. It solves real mowing problems. These are the issues that have kept homeowners from fully trusting earlier smart mowers.

If you’re wondering whether the X4 is really worth the jump over other models like the X3, i Series, or competitors like Husqvarna and Worx, here’s what makes it truly different.

What can the X4 do that others can’t?

1. Zero-Turn and All-Wheel Drive Equals True Set-and-Forget

Previous Navimow models like the X3 AWD were solid on slopes. The X4 takes it further. It’s the first in the lineup to offer all-wheel drive combined with true zero-turn steering.

That means it doesn’t just handle hills. It can navigate tight spaces, spin in place, and confidently climb up to 40° inclines without digging in or getting stuck. You won’t have to babysit it or rescue it from rough patches.

Think of it like this: AWD helps you climb. Zero-turn helps you finish the job cleanly. Together, they make this mower feel almost like a landscaper behind a ZTR mower.

2. Faster Work, Bigger Blades, Better Results

The X4 uses a new dual-disc system with 12 hardened blades. It’s not just about width (43 cm cut path). It’s about serious cutting power.

It runs on two 180W motors that chew through thick, wet, or tall grass without missing a beat. That power lets it mow faster and finish in fewer passes.

Other mowers might take days to clean up an acre. The X4 can finish about an acre in 11 hours. And it does it with a clean edge.

3. No More Antenna? Yes and No

One big leap with the X4 is that many users won’t need an external GPS antenna anymore. It uses RTK with EFLS 3.0. This gives faster signal lock, better coverage near trees, and avoids the signal dropouts older systems struggled with.

If you’re in a rural U.S. area without full NetRTK coverage, no problem. The antenna is still available, and the X4 supports it out of the box. You get flexibility with no compromises. Earlier models required a fixed antenna location to function properly.

Why is it priced so close to the X3?

That’s one of the smartest moves Segway made. The X4 is priced just a bit above the X3, yet it brings a serious jump in performance and reliability.

They didn’t waste money on flash. There’s no touchscreen and no unnecessary gimmicks. Instead, they focused on what matters:

• Smart, no-wire mapping that just works
• Quiet but powerful brushless motors
• Terrain-handling that actually handles terrain
• Home Assistant support
• Strong build quality

This mower isn’t about marketing specs. It’s about finally not thinking about your lawn anymore.

What didn’t they include, and why?

During their AMA, the product manager explained they planned to include an auto-trimmer but chose not to. Instead, they focused their engineering on perfecting all-wheel drive and zero-turn. That was the right call.

It shows they prioritized real-world performance over add-ons that sound good but often disappoint.

So who is the X4 for?

• You’ve got a hilly or uneven yard and other robots couldn’t handle it
• You want a setup with no boundary wire, no trenching, and minimal manual tweaking
• You care about clean cutting, especially along edges and fence lines
• You’re looking to replace your zero-turn or riding mower with something smarter

Bottom Line

The Navimow X4 isn’t just a new model. It’s a breakthrough. It finally brings robotic mowing to properties that are larger, steeper, or more complex. And it does it without the hand-holding.

Whether your lawn is three-quarters of an acre or up to 1.5 acres, the X4 has the wheels, the blades, and the smarts to handle it on its own.
