Can I use both systems on the same mower?

On one of these robots, yes. The Husqvarna Automower 450X NERA ships as a boundary-wire mower, and its record states that EPOS satellite RTK positioning with app-drawn virtual boundaries is available as an accessory (EPOS Plug-in module plus an EPOS Reference Station). The Husqvarna Automower 430XH runs on boundary wire with GPS-assisted navigation that steers coverage but does not replace the wire. The Worx Landroid M 20V records boundary wire only, and the Mammotion LUBA 3 AWD 5000 is wire-free, fusing LiDAR with RTK.

Does boundary wire work if it gets wet or covered by grass?

Wet grass does not block the magnetic signal from a properly buried or surface-laid wire. However, if the wire is damaged (cut or pinched), the signal fails. Grass growth over the wire itself does not typically disable it, though corrosion after years of wet soil can degrade signal strength.

What happens to an RTK mower if it loses GPS signal mid-mow?

It varies by model. For the Husqvarna Automower 450X NERA fitted with EPOS, owner reports in its record describe the mower going into standby when positioning drops, waking after about 30 minutes, and resuming work if the signal has returned. The Mammotion LUBA 3 AWD 5000 record says its correction data arrives over a built-in 4G module and that precision degrades where cellular coverage is poor, but it does not describe what the mower does when the signal drops mid-mow.

Is RTK GPS correction always a paid service?

Not on every system. The Husqvarna Automower 450X NERA, when fitted with EPOS, takes its correction from an EPOS Reference Station mounted on the property with clear sky view and mains power, bought as an accessory. The Mammotion LUBA 3 AWD 5000 needs no base station: correction arrives over its built-in 4G module through Mammotion's iNavi service, which its record says is included for three years. The record does not state the renewal terms after that period.

How do I protect boundary wire from damage long-term?

Bury the wire at least 2 inches deep, use a conduit if installing near frequently-tilled areas, and mark its path with paint or flags during the first season. Surface-laid wire is faster to install but more prone to accidental damage from foot traffic or lawn tools.

Boundary wire vs RTK robot mowers: which is worth the install effort?

Two ways to tell a robot mower where the lawn ends: lay a wire yourself, or let satellite corrections and sensors set the edge. This page compares the work each one asks before the first mow.

What each way of setting the edge asks of you

The Husqvarna 435X AWD is a wire mower: the owner lays the boundary wire, and the box holds none. The LUBA 3 AWD 5000 needs no wire but needs Wi-Fi or 4G coverage over the lawn.
