Where Gardena Wins
Lower upfront cost. At $750, the Gardena is $510 less than the NO Wire model, making it accessible for budget-conscious buyers with small lawns.
Quiet operation. Gardena markets this model as “SILENO” with a noise rating of 58 dB, which is whisper-quiet. It won’t disturb neighbors or outdoor activities.
Proven simplicity for small yards. The boundary wire system is well-understood and reliable for lawns under 0.25 acres. Installation is straightforward for a simple, open yard without many obstacles.
Stronger review volume. With 367 reviews, the Gardena has a much larger feedback base, giving a more reliable picture of real-world performance—even if the average rating is lower.
Where NO Wire Wins
Larger capacity. The NO Wire model handles up to 0.9 acres—nearly four times the Gardena’s maximum. It’s designed for substantial lawns, not just small city plots.
No boundary wire installation. The RTK-GPS + 4-eye vision system eliminates the need to bury guide wires around the lawn perimeter. This saves significant installation time and avoids wire damage from digging or landscaping.
Higher user satisfaction. With a 4.1/5 rating from 202 reviews, owners report fewer issues and more consistent mowing results. The advanced navigation handles complex yard shapes, obstacles, and slopes better.
Future-proof technology. Vision-based navigation adapts to changes in the lawn (new plants, moved furniture) without rewiring, and the system learns the yard over time.
Which Should You Buy
Buy the Gardena SILENO City if:
- Your lawn is 0.25 acres or smaller with simple, open shape
- You want the lowest possible investment in robotic mowing
- Quiet operation is a priority (close neighbors, early morning mowing)
- You don’t mind spending an afternoon installing boundary wire
- You prefer a well-established brand with wide parts availability
Buy the NO Wire model if:
- Your lawn is between 0.25 and 0.9 acres, or has complex shapes/paths
- You want to avoid burying boundary wire (or have hardscape, gravel, or tree roots that make wiring difficult)
- You’re willing to pay more for higher reliability and better user reviews
- Your yard has many obstacles (trees, flower beds, play equipment) that confuse wire-guided mowers
- You want a system that can handle future yard changes without rewiring
For most homeowners with a typical suburban lawn between 0.25–0.5 acres, the NO Wire model’s higher rating and wire-free convenience justify the price
