Gardena Sileno Life 750 · Husqvarna Automower 305

Random-pattern cutting inside a fixed wire keeps the machine simple and the setup permanent. You get an even lawn from cutting often; you do not get route planning or obstacle avoidance.

Wire perimeter scales with yard size. A 5,000 sqft yard requires 300+ linear feet of buried wire; installation and annual inspection costs rise proportionally. Expansion requires re-installation.

Lawns with complex topography, slopes, or frequent obstacles

No avoidance capability; slopes >15°, rocks, toys, or garden furniture will cause collisions or stalling requiring manual recovery.

Users wanting wire-free, zero-setup autonomous operation

Boundary-wire infrastructure is mandatory. RTK or vision-based alternatives not available on this model.

Large estates or multi-zone properties over 750 sq m

Rated for 750 sq m maximum; properties larger than this exceed rated coverage and would require multiple units.

Wireless or GPS-only boundary requirement

Buried boundary wire is the sole positioning method; no GPS alternative available. Households unable to install perimeter wire should skip the entire Automower 305 line.

Yards steeper than the 40% working-area rating

Husqvarna caps the 305 at 40% (22 degrees) inside the working area and 15% where the boundary wire runs, so ground that is within rating in the middle of the lawn can still be out of rating at its edge. Owner reports document traction loss and uphill stalling near the limit, especially on wet grass.

Lawns beyond 600 sqm (about 6,450 sqft)

Husqvarna's rating stops at 600 sqm. Larger lawns need a higher-capacity model: the 115H covers roughly two to three times the area of the 305. Splitting a bigger lawn across zones or additional charging stations adds cost without adding rated capacity.
