The Husqvarna Automower 310 has long held a benchmark position in the mid-sized garden robot mower segment. Since its initial launch, the model has evolved: buyers interested in an Automower 310 in 2026 face several variations (310 classic, 310 Mark II, 310E NERA) with distinct features. Comparing these versions allows one to assess what each variant concretely offers, and especially to determine which one suits a given terrain.
Automower 310, 310 Mark II, and 310E NERA: Technical Differences
| Feature | Automower 310 (classic) | 310 Mark II | 310E NERA |
|---|---|---|---|
| Maximum Area | 1,000 m² | 1,000 m² | 1,500 m² |
| Slope Capacity | Up to 40% | Up to 40% | Up to 40% |
| Navigation | Boundary wire | Boundary wire | Wireless (EPOS/RTK) |
| EdgeCut Function | No | No | Yes |
| Runtime / Recharge | Comparable | About 60 min / 60 min | Variable depending on area |
| Positioning | Entry-level | Mid-range, complex gardens | Mid-high range, wireless |
The table highlights a point that older tests of the classic 310 do not cover: the 310 Mark II explicitly targets gardens with slopes and narrow passages, where the original model was limited to more basic operation. For a relatively flat and open terrain, the classic version remains functional. As soon as the terrain becomes more complicated, the Mark II takes the advantage.

Installation with Wire or Wireless Navigation: The Real Choice Criterion for the Automower 310
The issue of boundary wire remains the main point of friction when purchasing a Husqvarna robot mower. The classic 310 and Mark II versions require the installation of a buried or ground-fixed boundary wire, while the 310E NERA operates without a wire thanks to EPOS technology.
What the Wire Implies in Daily Use
Installing the boundary wire takes several hours for a garden of a few hundred square meters. Each flower bed, tree, or obstacle must be circumvented by the wire. An accidental cut (from a spade or an aerator) immobilizes the robot until repaired.
For gardens with numerous flower beds, hedges, and narrow passages, this constraint weighs on long-term maintenance. The Automower-Fans forum is filled with testimonials from users who hesitate between the 310 and 315 precisely because of the complexity of wiring on winding terrains.
EPOS Navigation on the 310E NERA
The NERA version eliminates this constraint. The delimitation is done via the app, and the robot manages its trajectories through satellite positioning. The time saved during installation is significant, and subsequent modifications to the garden (adding a flower bed, extending a patio) no longer require digging up a wire.
However, the additional cost of the NERA version compared to the Mark II is notable. For a simple and stable garden, the wire remains a proven and less expensive solution.
Edge Finishes: The Concrete Benefit of the EdgeCut Function
A recurring complaint about robot mowers concerns the strip of uncut grass along the edges. Most users have to go over it with a manual trimmer to achieve a clean result.
The 310E NERA incorporates the EdgeCut function, designed to significantly reduce the need for manual trimming. The robot approaches the lawn edges more closely and adjusts its trajectory to minimize the residual strip.
- On a lawn bordered by walls or patios, EdgeCut reduces manual touch-ups to just a few specific areas instead of a complete pass
- Along flower beds virtually defined, the result depends on the accuracy of the EPOS signal and the regularity of the ground
- For borders along a fence or enclosure, the improvement is noticeable but not total: a quarterly pass with a trimmer remains likely
This function represents a measurable time gain over an entire season. For a user who trims every week, this is a concrete argument in favor of the NERA version.
Automower 310 Mark II on Uneven Terrain: Slope Capacity and Complex Gardens
The Mark II boasts a slope capacity of 40%, which corresponds to a marked incline. On hilly terrain with gently sloping areas, this margin is comfortable. On steep slopes close to the 40% limit, the robot slows down and may require several passes to cover the area.
The differentiating factor of the Mark II compared to the classic 310 lies in its management of complex gardens: narrow passages between two flower beds, L-shaped areas, corners behind a garden shed. The improved navigation system reduces unnecessary back-and-forth movements and overall mowing time.
For a rectangular and flat garden, this additional capacity does not provide a tangible benefit. The Mark II is justified when the terrain presents at least two constraints among the following:
- Slope greater than 25% in part of the area
- Three narrow passages or more (less than two meters wide)
- Mowing areas separated by paths or stairs
- Presence of many fixed obstacles (trees, poles, drains)
A garden that does not meet any of these criteria does not need the Mark II. The classic model, if still available, or an Aspire R4 for smaller areas, will suffice.
Which Automower 310 to Choose Based on Your Garden
The choice between the three versions depends on two variables: the complexity of the terrain and the tolerance for wired installation. A flat garden of a few hundred square meters without any particular obstacles works very well with a classic 310 or a Mark II. A hilly terrain with narrow passages fully benefits from the Mark II. A garden that regularly evolves (new landscaping, extensions) or exceeds 1,000 m² points towards the 310E NERA.
The EdgeCut function and the absence of wire are the only two technical arguments that justify upgrading to the NERA version. If edges and wired installation are not an issue, the Mark II remains the best performance-price ratio in the current 310 range.
