Frequently Asked Questions

Navimow X450 vs X430: Which Should You Buy?

The X430 and X450 are the same mower underneath: same AWD Xero-Turn chassis, the same RTK and vision navigation, the same 84% (40°) slope rating, and the same VisionFence obstacle detection. The only real difference is coverage. The X430 handles lawns up to 3,000 m² and costs $5,499. The X450 stretches to 5,000 m² for $5,999.

Buy the X430 if your mowing area sits comfortably under 3,000 m². You get identical hardware for $500 less. Buy the X450 if you're close to that 3,000 m² mark, managing multiple zones, or planning to add garden beds, a new turf area, or an extra paddock down the track. Running out of mapped capacity on a mower you've already installed is a bigger headache than paying the extra $500 upfront, so for schools, clubs, and contractors managing grounds that tend to grow, size up rather than cut it fine.

Is the Navimow X450 Worth the Investment?

For a lawn anywhere near its 5,000 m² limit, yes. Compare $5,999 against what a property that size actually costs to maintain: a contractor mowing 5,000 m² weekly through a full season, or your own time on a ride-on every weekend for years. The X450 also copes with terrain most mowers can't. It climbs a 40° slope, crosses a 7cm obstacle, and cuts within 5cm of an edge without the scrubbing and rutting a normal zero-turn or robotic mower leaves behind from repeated tight turns. At 68 dB(A) it's quiet enough to run before 7am or after dark, so it works around your schedule instead of the other way round.

Where the X450 isn't worth it: a flat, simple lawn under 3,000 m². The X430 does exactly the same job on that size block for $500 less, and there's no functional gain from paying for coverage you'll never use. The X450 earns its price on genuinely large, sloped, or complex properties, not a standard suburban block.

How Long Does It Take a Navimow X450 to Mow Your Lawn?

It isn't built to cut all 5,000 m² in one sitting, and that's by design. Once it's mapped your property, the X450 runs on a schedule you set in the app, mowing in short, frequent sessions rather than one long session, which also happens to be better for the lawn since it mulches fine clippings back in instead of leaving clumps from an overdue cut.

When the battery runs low it returns to the dock, recharges in around 100 minutes, then heads back out to pick up where it left off. Covering a full 5,000 m² block means several charge cycles spread across a day or two rather than one continuous run. The first week is the slowest part, since it's learning your zones, edges, and no-go areas. After that, it settles into the schedule and you stop noticing it's there, which for most of our large-property clients is the entire point.

Does the Navimow X4 Work With Weak GPS Coverage?

Both methods the X4 series supports, Network RTK and a physical antenna, are still GNSS positioning. That means the mower always needs a clear view of the sky to pick up satellite signals directly, the same way a phone needs sky view to get a GPS fix. Network RTK doesn't change that requirement.

What Network RTK removes is the need to install a physical reference antenna on your property. Instead of a local antenna sending correction data to the mower over a short-range radio link, the correction stream comes from a network provider over cellular data, included free for the first year through Connect+, then $49.50 a year. Network RTK is available across our sales regions in Australia and New Zealand.

If you use the physical antenna setup instead, satellite visibility still matters for both the antenna and the mower. The antenna also needs to stay within reliable radio range of wherever the mower is working, around 200m by default. On a larger block, or where trees or buildings sit between the antenna and parts of the lawn, a Signal Enhancement Antenna extends that communication range (sold separately). It boosts the radio link to the mower, not satellite reception.

Where either setup runs into real trouble is heavy tree canopy or anything else blocking open sky across the mowing area itself, since that affects satellite reception no matter which positioning method you use. If a property has patchy sky view (dense trees, tall fences, structures overhanging the lawn), flag it before ordering so we can talk through what to expect.

Navimow X4 vs Other Robot Mowers: Which Should You Buy?

Most robot mowers still rely on buried boundary wire, which means a full day trenching cable around the lawn before the mower ever runs, and re-digging any time you change the layout. The X4 series maps the property using RTK and vision instead, so there's no wire to install or maintain.

The driveline is the other big split. Most large-lawn robot mowers run 2WD, which struggles the moment grass is wet or a slope gets past mild. The X4's AWD, dual suspension, and Traction Control System are rated to an 84% (40°) gradient, well past what a 2WD unit will climb confidently. Obstacle handling is different too: VisionFence identifies over 200 object types and reroutes around them, rather than the bump-and-reverse approach most sensor-based mowers use, which means less time spent freeing a mower wedged against a garden bed. Xero-Turn steering also switches between standard steering and pivot turning depending on the terrain, so it doesn't scrub or rut the turf on tight turns the way plenty of robotic and ride-on mowers do over time.

If you're weighing wire-free against wire-based, take wire-free. The install time saved alone justifies it. If you're weighing AWD against 2WD on anything with slope, damp grass, or uneven ground, AWD is worth paying for. Where the X4 series isn't the right call is a small, flat, simple lawn under a few hundred square metres, where our i-series models cost less and do that job just as well. The X4 earns its price on large, sloped, or complex properties, not modest suburban blocks.
