Navimow MowGate (2026): Price, Compatible Mowers, Install Specs and Why It's Sold Out

Quick Answer: The Navimow MowGate is a $449.99 double-door gate that sits in a cutout in your fence and unlocks itself when a Navimow robot mower approaches, so one mower can mow, and get back to its charger, across a fenced front and back yard. Per Navimow’s support center, it works with every current Navimow series except the H1 (i1, i2 AWD, i2 LiDAR, H2, X3, X4 and Terranox). It runs up to 9 months on four D batteries and needs a 37 × 22 in (93 × 54 cm) cutout on level ground, per the MowGate user manual. The catch: navimow.com lists it as sold out as of November 4, 2026, and Internet Archive snapshots show it has been out of stock since at least October 5.

A robot mower can only mow the lawn it can reach. If a fence and a closed gate split your yard in two, the usual fixes are bad ones: prop the gate open and hope the dog stays put, carry the mower over twice a week, or buy a second mower. MowGate is Navimow’s answer to that problem. The only comparable first-party product we found is Husqvarna’s Automower Fence Door ($534.99 MSRP), which fits seven Automower models and has no pet scan (compared below). Mammotion’s US store listed no gate among its 49 products on November 4, 2026, and we found none from Worx. Those brands rely on open passages instead (see our gate and passage width guide).

All specs below come from navimow.com’s US product page, the MowGate user manual (Navimow document 260114-A) and Navimow’s support-center FAQ articles, checked on November 4, 2026, unless we name another source. We found no independent MowGate review from a US or European outlet as of that date.

How MowGate works, step by step

Navimow’s support articles describe the crossing in five steps. The mower only uses the gate when it has a planned task in the zone on the other side, or when it needs to drive back to a charging station in the other zone.

1. Approach. The mower drives toward the gate, which it recognizes by the reflective markers on the panels. At night the mower switches its lights on; Navimow says the gate works in low light as long as the markers are visible.
2. Pet scan. About 0.5 m (1.6 ft) from the gate, the mower stops and performs a full 360° scan for pets within 1 m (3.3 ft).
3. Unlock. If no pet is detected, the mower moves to about 0.1 m (4 in) from the gate. The magnet on the mower triggers the gate’s Hall-effect sensor, and both panels unlock and swing open.
4. Pass. The mower drives through.
5. Lock. The gate swings closed and locks immediately, so a pet cannot push it open afterward.

The gate’s indicator light stays on for about 10 seconds after you fit the batteries, then switches off to save power. It lights up again whenever the gate senses the mower’s magnet. Several Navimow mowers can share one MowGate, as long as each one is a supported model with its own magnet installed.

Which Navimow mowers work with MowGate

Navimow’s support center (article updated September 7, 2026) says MowGate supports “all Navimow mower models except for the H1 series.” The user manual lists a separate magnet-fitting step for each series. Prices are navimow.com US list prices on November 4, 2026.

Navimow’s support center also says MowGate is “not compatible with third-party accessories or custom gate systems” and that it does not recommend using it with non-Navimow mowers. If you own a Husqvarna, Mammotion or Worx mower, MowGate is not an option.

What MowGate really costs, relative to your mower

At $449.99, MowGate is priced like a mid-size accessory, but the share of your total spend depends heavily on which Navimow you own. Here is the gate’s price as a percentage of each mower’s navimow.com list price on November 4, 2026.

Two numbers frame the decision. First, MowGate costs $349 less than a second Navimow i105 ($449.99 vs $799), which is the cheapest way to get a second robot mower with its own station into the second zone. Second, for an i105 owner the gate adds 56% to the price of the mower, so on a small two-part lawn a cheaper fix may make more sense (see the alternatives below). Running costs are low: one set of four D cells per mowing season, by Navimow’s 9-month estimate.

Before you add the gate, check that your mower can handle the combined area. MowGate does not add mowing capacity. A Navimow H210 rated for about 0.25 acre still mows about 0.25 acre when that area is split across two fenced zones.

Installation requirements and fine print

The cutout. You cut a 37 × 22 in (93 × 54 cm) opening into the bottom of the fence, using the cardboard template in the box. For mesh fences the manual calls for a reciprocating saw or an angle grinder; for harder fences, the same tools plus an electric drill for the mounting holes. On wobbly mesh fences you fit triangular supports on both sides. Navimow’s support FAQ lists the box contents as the manual, the template, the magnet with its holder and 3M adhesive, 8 ground pegs, 4 brackets, 20 screws, 16 mounting straps and an Allen key.

Level ground only. The manual’s installation diagrams reject a slope, a mound, an uneven fence line and a gate set on a raised base. Navimow’s support center adds that uneven ground “may prevent the robotic mower from passing through smoothly and could potentially trigger error codes,” and recommends leveling the spot first.

Width, compared with an ordinary passage. The 37 in cutout is narrower than the 100 cm (39.4 in) minimum Navimow publishes for ordinary mapped channels and fence gaps on its X4, H2 and i2 LiDAR Pro mowers (details in our passage width guide). Navimow publishes no separate width rule for MowGate beyond the template; the app sets the gate up as its own map element (the MowGate icon), not as a plain channel. For scale, the H2 is 17.5 in wide and 11.6 in tall per its own manual, so it clears the opening with room to spare.

Map setup. You need a mowing zone on each side of the gate. In the Navimow app the path is Home > Settings > Map management > Edit map > Add more, then the MowGate icon. The app then guides the mower through the gate once.

Maintenance. Brush off dirt, wipe mud with a damp cloth and keep the reflective markers clean. Navimow recommends WD-40 gel lube or a similar product on the frame joints and hinges. The gate can stay outdoors through winter, but Navimow says to take the batteries out first. See our winter storage guide for the mower side of that job.

MowGate error codes and what they mean

Navimow publishes four error codes that can appear while a mower is passing through MowGate. These are the most useful troubleshooting facts on the gate, because they show where crossings tend to fail.

If the mower simply will not go through, Navimow’s checklist is short: confirm the magnet is fitted (without it, the mower pushes against a locked gate), clean the reflective markers and the mower’s camera, and remove objects, people or animals near the gate. A pet detected mid-crossing will also stop the mower, by design.

MowGate vs Husqvarna Automower Fence Door

Husqvarna’s Automower Fence Door does the same basic job for Automowers: it unlocks when the mower approaches and locks after it passes. The design is older and simpler. Its operator’s manual dates from 2022 and describes operation with the boundary and guide wire, with no camera or pet scan. Husqvarna’s dealer site now also lists the wire-free 410 iQ, 420 iQ and 440 iQ as compatible. The figures below come from Husqvarna’s US dealer site and that manual.

The practical difference is the fence. Husqvarna’s manual says installing its door in chain link or wire fences “is not recommended,” while MowGate is designed for mesh fences, with triangular side supports for unstable ones. The Husqvarna door also needs those separate mower kits on top of the $534.99, so the real cost gap is wider than $85. Neither gate works with the other brand’s mowers. If you are choosing a Husqvarna, our Automower 410 iQ review covers one of the compatible models.

Pet safety: what MowGate does and doesn’t promise

The pet scan is what separates MowGate from a simple flap or Husqvarna’s Fence Door. The mower checks a 1 m (3.3 ft) radius before unlocking, and the gate re-locks after every pass, which Navimow says “prevents pets from pushing the gate open on their own.” That is a sensible design, but it is not a guarantee. A dog that arrives at a run after the scan, or a cat that simply climbs the fence, is outside what the gate can control. For a household where an escape would be dangerous, keep pets inside during scheduled zone changes for the first few weeks and watch a few crossings yourself. Our robot mower guide for dog owners covers the mower-side pet detection.

Stock status: when MowGate was available

navimow.com is the only US MowGate listing we could track over time. Here is what the product page showed, based on Internet Archive snapshots and our own check on November 4, 2026.

The price has not moved since launch. Navimow has not published a restock date. Its support center points buyers to the official store and to authorized dealers listed under “Where to Buy” on navimow.com, so a local Navimow dealer is worth a call if you need one before spring.

If MowGate is sold out: your options

• Wait for the restock. If the gate is the right fit, the “Notify Me When Available” button on navimow.com is the only official signal. Navimow has not given a date.
• Use an open passage on a schedule. Leave an ordinary gate open during set mowing hours and keep pets inside then. This costs nothing, but it only works if the gate opening meets your mower’s passage spec, and it needs discipline.
• Carry the mower between zones. An H220 weighs 35.82 lb per its manual. That is manageable for a weekly move, not for a daily schedule.
• Buy a second small mower. A Navimow i105 at $799 costs $349 more than MowGate but adds mowing capacity and needs no fence work. It makes sense when the second zone is small, such as a front lawn.

The bottom line

The Navimow MowGate solves a real problem that only Husqvarna also addresses with a first-party product: a fenced yard split into zones, with pets that must stay in. The design is thoughtful, with a pet scan before every crossing, an auto-locking double door, D-battery power that avoids running a cable, and support for every current Navimow except the old H1. The trade-offs are the $449.99 price, which is more than half the cost of an i105, and the 37 × 22 in fence cutout on level ground. The main obstacle right now is availability: navimow.com has listed it as sold out since at least October 5, 2026. If you own an i2, H2, X3 or X4 and your fence line is flat, it is worth waiting for. If you own an i105 and the second zone is small, compare it against a second mower first. For the rest of the lineup, see our Segway Navimow buying guide.
