Gardena smart SILENO city — 500 m²
Ref. 970550310
The smart SILENO city by Gardena is a compact 7.3 kg robotic mower for lawns up to 500 m², with a maximum slope of 35% and a sound level of 57 dB(A). Its 16 cm cutting width, height-adjustable from 2 to 5 cm, comes with SensorControl, which automatically adjusts mowing frequency to grass growth throughout the whole mowing season, without manual reprogramming.
The boundary wire defines the mowing area, laid at a distance from obstacles that varies with what's nearby (a tree, a border). The mower overhangs the wire slightly before turning, for a clean cut to the edge with no manual finishing. Contact with an obstacle simply triggers a change of direction.
It installs with a traditional boundary wire, but stands out with full app control through the GARDENA smart system for setup and remote monitoring of the mowing schedule from a smartphone. Its 18.5V lithium-ion battery powers an average mowing time of 65 minutes. Certified IPX5, this Gardena robotic lawn mower suits mid-sized gardens fitted with a boundary wire, with added mobile control on top.
