How wide does a gate need to be for a robot lawn mower?

It depends on the navigation system, and the range is wider than most shoppers expect. Husqvarna and Gardena's wire-guided mowers can pass through a gate as narrow as 60 cm (24 in) if you install a separate guide wire down the middle of the passage, per Husqvarna's own installation support documentation. Segway's Navimow X4, H2 and i2 LiDAR Pro instead require a minimum 100 cm (39.4 in) width and 40 cm (15.75 in) height for any passage, gate or fence gap, per Segway's official support site — with no obstacles inside a full meter of the channel.

Is a standard fence gate wide enough for a robot mower?

Sometimes not. The industry-standard residential pedestrian gate is 36 inches (91 cm) wide, with a common range of 32-48 inches. That comfortably clears Husqvarna and Gardena's 60 cm (24 in) guide-wire minimum, but it's narrower than Segway Navimow's official 100 cm (39.4 in) passage requirement — meaning a normal 36-inch side-yard gate can fail a spec sheet on a RTK/LiDAR mower that never needed a buried wire at all.

Does Worx Landroid Vision really fit through narrow gaps?

Worx's own marketing says the Landroid Vision 'effortlessly goes through tight passages — as narrow as the mower itself' using its camera and no guide wire. Worx's own installation guidance for narrow passages, however, states the passage must be wider than 1 m (about 39 inches) for the mower to navigate it safely — nearly identical to Segway's documented minimum, and still wider than a standard 36-inch gate. The marketing line describes the mower's physical width; the manual describes what the navigation system actually needs to track reliably.

What's the narrowest robot mower gate spec available?

Two approaches tie for narrowest, and neither is a 'boundaryless' flagship. Husqvarna and Gardena's classic boundary-wire mowers need just 60 cm (24 in) between wires when a guide wire is added down the passage's center. Mova's small-yard ViAX line (250/300/500) is rated by Mova to navigate passages as narrow as 60 cm (23.6 in) using AI mapping alone, no wire required — see our full Mova ViAX breakdown for pricing and coverage.

Can I widen a gate or passage instead of buying a different mower?

Usually the cheaper fix is a guide wire, not a wider gate. On boundary-wire brands, adding a single guide wire down the center of an existing narrow passage drops the required width from 2 m (6 ft 6 in) to 60 cm (24 in), per Husqvarna's own support documentation — a $20-30 spool of wire and an hour of work, versus a fence-rebuild project. Wire-free RTK/LiDAR models don't support a guide-wire workaround the same way, since they navigate by satellite or laser rather than following a buried signal — for those, the passage itself has to meet the published minimum.

Robot Mower Gates and Narrow Passages: The Width Your Gate Actually Needs (2026)

Quick Answer: A robot mower’s real gate-width requirement depends entirely on how it navigates. Husqvarna and Gardena’s wire-guided mowers need just 60 cm (24 in) between boundary wires if you add a guide wire down the passage — per Husqvarna’s own support documentation. Segway’s Navimow X4, H2 and i2 LiDAR Pro instead require 100 cm (39.4 in) minimum width per Segway’s official spec, and Worx’s Landroid Vision manual states passages must be wider than 1 m (about 39 in) despite marketing that says it fits through gaps “as narrow as the mower itself.” A standard residential gate is 36 in (91 cm) — wide enough for the wire-guided minimum, narrower than both wire-free flagship specs.

That gap between marketing copy and the installation manual is the whole story here. Before you buy a mower for a yard with a side gate, driveway strip, or narrow connector between lawn sections, check the actual documented passage spec — not just the promise that the mower “handles tight spots.”

The honesty check: marketing width vs. manual width

Worx advertises that the Landroid Vision “effortlessly goes through tight passages — as narrow as the mower itself” — and it’s true that the mower body itself is about 19 inches wide on the WR210 model. But that’s a description of the machine’s physical footprint, not what its camera-based navigation needs to track a boundary reliably. Worx’s own narrow-passage installation guidance puts the real minimum at wider than 1 m (about 39 in) — almost identical to Segway Navimow’s official 100 cm spec for the X4, H2 and i2 LiDAR Pro, which also requires 40 cm of vertical clearance and no obstacles within a full meter of the channel.

That number matters because it’s wider than a standard residential gate. The industry-standard pedestrian gate is 36 inches (91 cm), with most residential gates falling in a 32-48 inch range. A 36-inch gate clears the wire-guided 60 cm minimum with room to spare — but it fails Segway and Worx’s documented 100 cm/39-inch spec by three inches. If your side-yard access is a standard 36-inch gate and you’re set on a “boundaryless” RTK or vision flagship, measure before you buy; you may need to widen the gate, choose a different route, or pick a mower with a genuinely narrower documented minimum.

Wire-guided mowers: the narrowest real option

If your yard has a genuinely tight side-yard gap — under a meter — a wire-guided mower is still the narrowest documented option on the market. Husqvarna’s support documentation lays out two scenarios: without a guide wire, the two boundary-wire runs on either side of the passage need at least 2 m (6 ft 6 in) between them so the mower doesn’t cross its own signal. Add a single guide wire down the center of the passage, and that minimum drops to 60 cm (24 in) between boundary wires, with the guide wire itself kept at least 30 cm (12 in) from either boundary line. It’s a $20-30 spool of extra wire and roughly an hour of extra install time — far cheaper than rebuilding a fence gate to meet a wire-free flagship’s wider spec.

Wire-free small mowers built for tight lots

Not every wire-free mower needs a full meter. Mova’s small-yard ViAX line (250/300/500) is purpose-built for exactly this problem — cut-up lots with gates, side yards and narrow connectors — and Mova rates its “UltraEyes 2.0” AI mapping to navigate passages as narrow as 60 cm (23.6 in), matching the wire-guided minimum without any wire at all. See our full Mova robot mower guide for ViAX pricing and coverage specs. It’s the wire-free exception that proves the rule: a narrow-passage rating is a specific engineering claim a brand either publishes and backs up, or doesn’t — it isn’t something “boundaryless” navigation guarantees by default.

Robot mower passage width, by the numbers

60 cm / 24 in: Husqvarna’s minimum boundary-wire spacing through a passage when a guide wire is added — the narrowest documented spec among wire-based mowers, per Husqvarna support.
100 cm / 39.4 in: Segway Navimow’s official minimum passage width for the X4, H2 and i2 LiDAR Pro, plus a 40 cm height minimum, per Navimow support.
36 in / 91 cm: The industry-standard residential pedestrian gate width — wide enough for a wire-guided passage, three inches short of Segway and Worx’s wire-free flagship minimums.

The bottom line

Check the manual spec, not the marketing line, before you buy a mower for a yard with a tight side gate or narrow connector. If your gate is a standard 36 inches, a wire-guided Husqvarna Automower with a guide wire (24-in minimum) or a purpose-built small mower like the Mova ViAX (23.6-in minimum) will actually fit; a “boundaryless” RTK or vision flagship rated for 39-40 inches may not, no matter how the ad copy describes it.
