Gardena Sileno

Quietest robotic mowers in their class. Boundary wire for ¼–½ acre. Part of the Husqvarna Group — same reliability, lower noise.

Gardena is owned by the Husqvarna Group — same parent company as Husqvarna Automower. The key difference is noise: the Sileno Minimo runs at 57 dB(A), making it the quietest option for noise-sensitive neighborhoods. Boundary wire installation required, but the setup process is well-documented and the app is smooth.

Lower slope ratings (25–30%) mean they're best for flat to moderately sloped yards. For steeper terrain, look at Husqvarna's higher-slope models. Full comparison in our lawn size guide.
