The Gardena Sileno range remains one of the market references for robotic mowers with perimeter wire in 2024. In light of the rise of GPS models without wires (Mammotion, Dreame, Navimow), how do the various Sileno models compare to each other, and how do they fare against this new competition? This article measures the differences based on the criteria that matter: noise level, slope management, anti-theft security, and longevity of after-sales service.
Noise Level of Gardena Sileno: A Measurable Advantage Against the Competition
Noise remains one of the primary complaints among neighbors regarding robotic mowers. In this area, the Sileno models show a clear advantage. Gardena Sileno models emit between 58 and 60 dB, while the market average hovers around 70 dB.

This difference, far from being trivial, has direct practical consequences. A robot at 58 dB can operate early in the morning or in the evening without generating audible nuisance from the neighboring property. Recent recommendations on protecting nocturnal wildlife further highlight the interest in programming mowing outside the hottest hours, which the low noise level of the Sileno makes possible without neighborhood conflict.
General comparisons in 2024 mention decibels in their technical sheets but rarely link this figure to practical use. A Sileno that allows for flexible mowing scheduling throughout the day, including during sensitive hours, represents a real organizational gain for gardens in densely populated residential areas. To delve deeper into the differences between the models in the range, a comparison of Gardena Sileno robotic mowers details the technical specifications of each version.

Comparison Table: Sileno City, Sileno Life, and Smart Sileno
The Sileno range is available in several versions targeting different garden profiles. The table below summarizes the selection criteria based on available data.
| Criterion | Sileno City / Minimo | Sileno Life | Smart Sileno |
|---|---|---|---|
| Type of garden | Small areas, simple terrain | Medium surfaces, narrow passages | Large areas, complex terrain |
| Noise level | 58 dB | 58-60 dB | 58-60 dB |
| Connectivity | Bluetooth | Bluetooth / Optional Gateway | Integrated connect module |
| Slope management | Moderate slopes | Medium slopes | Marked slopes |
| Anti-theft security | PIN code, alarm | PIN code, alarm | PIN code, alarm, geolocation |
| Installation | Perimeter wire | Perimeter wire | Perimeter wire |
The Smart Sileno stands out for its complete connectivity and ability to handle uneven terrain. In contrast, for a flat small garden, the Sileno City or Minimo meets the need without extra cost.
Anti-theft Security of Gardena Robots: An Underestimated Criterion in Comparisons
Comparisons of robotic mowers focus on the area covered, battery life, and noise. Anti-theft security appears at best as a line in a specifications table. This is a blind spot for buyers, while the theft of robotic mowers increases each year with the democratization of these devices.
Gardena Sileno has integrated a multi-level protection system for several generations:
- Mandatory PIN code at startup, which blocks the use of the robot in case of unauthorized movement
- Sound alarm triggered by lifting the robot out of its mowing zone
- Geolocation via connect module on Smart Sileno models, allowing the device to be tracked in case of theft
This combination of PIN, alarm, and geolocation places the Sileno among the best-protected robots on the market. Recent wireless models sometimes offer a PIN code, but integrated geolocation remains rare at equivalent prices.
Perimeter Wire vs. GPS: Terrain Reliability of Sileno on Complex Gardens
Wireless robotic mowers (GPS guidance or camera vision) dominate general comparisons in 2024. Their simplified installation, without wires to bury, appeals to first-time buyers. However, this initial time-saving masks a behavioral gap on gardens with complicated geometry.
The Sileno with perimeter wire maintains proven reliability on wired gardens, especially those with flower beds, isolated trees, or narrow passages between two lawn areas. The wire guides the robot with a precision that GPS, subject to signal loss under trees or near buildings, does not consistently guarantee.
Field experience shows that the Sileno handle narrow passages thanks to their adapted cutting width and the navigation logic dictated by the wire. GPS models are improving in this regard, but blockage situations remain more frequent on plots with many closely spaced obstacles.
Availability of Gardena Spare Parts
Another differentiator rarely discussed concerns after-sales service and availability of spare parts. Gardena, backed by the Husqvarna group, has a dense distribution network in Europe. Blades, batteries, wheels, electronic boards: parts remain available for several years after a model is discontinued.
For GPS robot brands that have recently entered the market, this depth of spare parts catalog is not yet guaranteed. A robotic mower lasts on average several seasons, and the ability to replace a battery or blade within a few days impacts the total cost of ownership as much as the initial purchase price.
The choice between a wired Sileno and a wireless GPS robot is not limited to ease of installation. The very low noise level of the Sileno, their comprehensive anti-theft system, and the sustainable availability of spare parts constitute three concrete criteria that standard technical sheets do not highlight. For a garden already wired or with complex geometry, the Sileno remains a technically solid option against the GPS alternatives of 2024.
