Owners should verify local third-party service availability before any significant repair.
Bottom lineThe product continues to operate mechanically, but the service exit converts routine maintenance into a parts-sourcing problem with no manufacturer backstop.
ImpactOn autonomy
- Autonomous operation unaffected; underlying wire-guidance hardware unchanged
- No firmware or software updates expected going forward
On readiness
- Official parts and service channel closed; owner repair complexity increases significantly
- Warranty coverage no longer available through Honda dealer network
- Aftermarket blade and wire sourcing becomes the only supported maintenance path

Service Exit Scope
Honda’s authorized dealer network in the US and Canada stopped accepting Miimo service appointments and stocking factory parts. This covers the HRM310 and related Miimo variants. The exit does not disable existing units; no remote kill or firmware change was applied.
Owner Impact
Boundary-wire signal transmitters, charging dock contacts, and proprietary blade assemblies are the components most likely to require replacement. Owner reports documented increasing difficulty sourcing these through third-party channels after the dealer exit. A small number of independent service shops with existing Miimo experience remained active in select markets.
Parts Availability Status
Third-party blade replacements with compatible geometry have been available from aftermarket suppliers. Wire break repair kits are category-generic and broadly available. Charging dock electronics are the hardest-to-source component; no aftermarket equivalent was widely documented at the time of exit.

WatchingDealer coverage and whether Honda extends the Miimo line beyond these two wire-guided models.
Bottom lineThe HRM310's launch specifications and dealer footprint are well documented, but the automation Honda marketed still depends on a staked boundary wire and a narrower dealer network than "nationwide" implied.
ImpactOn autonomy
- Boundary-wire perimeter navigation and 360-degree contact sensors define initial obstacle handling.
- Three selectable cutting patterns give the HRM310 its launch-level route programming.
- No GPS, RTK, or camera-based mapping is included on this wire-guided model.
On readiness
- Honda Power Equipment dealers nationwide, except California, carried the HRM310 at launch.
- A two-year warranty and 30-minute self-charge cycle backed the mower's introduction.
- Setup requires staking a physical boundary wire around the lawn perimeter.

Honda's launch materials described the HRM310 as delivering automated, unattended cutting for "easy, beautiful lawn care.
Documented findingReaching that unattended operation requires the owner or a dealer to first install a perimeter boundary wire around the lawn, per Honda's own product documentation.Honda marketed the April 2017 launch as a nationwide dealer rollout.

Launch Specifications
Honda introduced the Miimo HRM310 on April 11, 2017 at a suggested retail price of $2,499, rated for lawns up to a half acre. The mower carries a 22.2V/1.8Ah battery, runs up to 30 minutes per charge, and self-charges in 30 minutes, according to Honda Power Equipment’s launch materials and RERmag’s April 12, 2017 coverage. It weighs approximately 26 pounds, cuts an 8.7-inch width, and adjusts from 0.8 to 2.4 inches in height.
Navigation and Safety
The HRM310 follows a perimeter boundary wire staked around the lawn and carries no GPS, RTK, or camera-based mapping. Honda’s launch materials describe independent 360-degree contact sensors and a floating cover that stop the mower on contact, along with three selectable cutting patterns.
Availability
Honda launched the HRM310 alongside the larger HRM520 ($2,799, 0.75-acre coverage, 60-minute runtime) at Honda Power Equipment dealerships nationwide, excluding California, according to press coverage from April 11, 2017. Both models carried a standard two-year warranty at introduction.
