5 Navimow Upgrades That Actually Work (and One to Skip)

Search “Navimow upgrades” and you’ll find accessory walls: garages, skins, bumpers, gold-colored blades. We’re a dealer and service center — we see which of these actually change how a mower runs, and which just change how it looks on the shelf.

Here are the five upgrades we run on our own demo units and recommend to customers, ranked by payoff per dollar. Two are free. And at the end, the popular one we tested and now tell people to skip.

1. Run 9 blades per disc — the 18-blade setup

The best cut-per-dollar upgrade on the machine, and it’s hiding under the disc covers. Every Navimow ships with 6 blades per cutting disc, but the discs are factory-drilled for 9. Under each protective cover are three unused, evenly spaced screw holes — fill them with OEM blades and you’re running 18 blades instead of 12, a 50% increase in cutting edge.

The payoff shows up exactly where a robot mower’s cut usually falls short: Bermuda and warm-season grass cut low, grass that leans after wind or rain, and the stragglers that survive pass after pass. Cost: one blade pack and fifteen minutes. Here’s the full walkthrough, including the two settings to adjust afterward.

2. Swap whole cutting discs, not individual blades

Turn a twelve-screw job into a two-minute one. We stock complete cutting discs with fresh OEM blades pre-installed — new screws included, torqued correctly at the shop. Come replacement day, you swap the entire disc instead of a dozen blades and screws, which saves 20–30 minutes and eliminates the two mistakes that cause most blade problems: reused screws and overtightening.

You’ll still be replacing blades every 4–6 weeks with daily mowing — this upgrade doesn’t change the interval, it changes how much of your Saturday the interval costs. Fair warning: they sell out about as fast as we can build them, but new shipments land weekly. Ask us.

3. Move the schedule into the dry window (free)

The cheapest cut-quality upgrade is a settings change. A mower scheduled overnight or at dawn spends its life cutting through the heaviest dew of the day — which means clumping, a ragged torn cut, a deck that packs up with wet clippings, and a higher disease risk on every fresh wound.

Shift the runs to late morning through afternoon, when the lawn is driest, and the mower cuts cleaner, clumps less, and goes longer between deck cleanings. The scheduling guide covers how to set it up well — and if you’re tempted by overnight mowing, read the dew section first.

4. Give the RTK antenna height and open sky (free)

The most underrated upgrade isn’t on the mower at all. Most people bolt the RTK antenna next to the charging dock because that’s where the kit came out of the box — but the dock and antenna are independent, and the antenna belongs wherever it sees the most open sky, even if that’s a roof gable or a pole across the yard.

A marginal antenna spot fails slowly: the mower works fine for a season, then starts drifting — cutting into beds, missing the same edge strip every week. Moving the antenna up and into the open is free and often transforms a flaky mower into a boring, reliable one. The 4 placement rules are here — on one heavy-canopy install we mounted the base 25 feet up after two other installers said the yard couldn’t be done.

5. Put strong WiFi over the lawn

For yards where the signal, not the cut, is the problem. If your Navimow drops connection, pauses mid-job, or pings you “lost connection” alerts, the fix usually comes from the networking aisle: an outdoor WiFi extender mounted on a shed or exterior wall. We used a WAVLINK AX1800 (around $160) — IP67 weatherproof, PoE-powered, and in repeater mode it turned one bar of house WiFi into strong coverage across the whole mowing area, roughly 250–300 feet of dependable open-air range.

Two Navimow-specific details: the mower’s radio is 2.4 GHz only, so that’s the band that matters, and once it’s connected you can set Only Wi-Fi in the app so it never falls back to a weak cellular link. The full install and settings walkthrough is here.

The upgrade to skip: titanium-coated blades

We tested them so you don’t have to. Gold “titanium” Navimow blades promise a sharper cut and longer life. On a laser edge reader, the OEM Segway blades measured sharper — both brand new and after a month of mowing. On a scale, OEM blades weighed about 25% more (2.5 oz vs 2.0 oz per 20 blades): more actual steel, thicker stainless, better edge retention. The titanium nitride coating is thinner than the cutting apex itself and wears through almost immediately.

The full head-to-head with all the measurements is here. Spend the money on OEM blades and change them on schedule — that’s the entire secret.
