Segway Navimow's previous large-garden range, now replaced by the X4. Capable on big, fairly flat lawns, but only worth it as discounted leftover stock.

Claims vs reality

Where the brand’s marketing and its own small print don’t agree.

  • They sayRated for 50% slopes.

    In practiceNavimow's spec page limits slopes at the boundary to 25%, so lawns that fall away at the edge need the map drawn with care. Source

  • They sayThe X4 is the X3's replacement.

    In practiceNavimow doesn't say so in as many words; the X4 simply took the X3's place in the UK X Series menu. The X4 differs substantially: four-wheel drive, no aerial and a wider deck. Source

Which version do you need?

The X315, X330, X350 and X390 share the same body, deck and navigation. They differ in battery, run time, rated area and the amount of 4G data included, which rises from 12 months on the X315 to 60 months on the X390. On a used or clearance unit, check how much of that data remains.

How it navigates and sets up

The X3 was unveiled in 2025 as Segway Navimow's large-garden range. It uses RTK positioning from its own satellite aerial, which you install near the dock (it supports a second aerial for big or awkward sites), combined with three cameras covering 300° and a time-of-flight depth sensor. There's no perimeter wire, but installing the aerial is an extra step compared with the network-RTK Segway Navimow X4 Series. See our navigation guide.

It is rear-wheel drive and rated for 50% slopes, with 25% at the boundary according to Navimow's spec page.

Cutting

A six-blade anti-clog disc cuts a 237 mm strip, narrower than you might expect on a mower rated for such large areas. Height is set in the app from 20 mm to 70 mm. Run time is 120 min–240 min depending on version, and Navimow quotes 60 dB(A) without saying how it was measured.

App, connectivity and security

The Navimow app handles mapping and schedules; 4G is built in with 12 months–60 months of data depending on version. Security covers a PIN, GPS tracking and alarms, and it works with Alexa and Google Home.

Running costs, warranty and support

Navimow's current UK policy gives 3 years on the mower and two years on the battery. Navimow still publishes support pages for older models, but it doesn't say how long it will keep releasing software updates for the X3.

Should you still buy one?

Only as clearly discounted leftover stock. The original RRP was £2,499–£4,999. The X4, from £2,199, drops the aerial, adds four-wheel drive and a much wider deck. The X3 remains worth considering if you need the 10,000 m² X390 or find a large version well below X4 prices, and your lawn is not steep.

Questions owners ask

Frequently asked questions

Is the Navimow X3 discontinued?

In the UK, yes. It has left Navimow's menu and all four store listings are unavailable, though the old product page still links to dealers who may have stock.

What does the X4 improve?

Four-wheel drive and an 84% slope rating, network RTK so no aerial is needed, and a 430 mm twin-disc deck. The X3 still offers a 10,000 m² version, which the UK X4 range doesn't.

Is the X3 still under warranty?

Navimow's current UK policy gives three years on the mower and two on the battery from purchase. Terms at the original sale may have differed, so check with the seller.
