Product details

The GARDENA Sileno City 350 lawn mower robot is designed for lawn areas up to 350 square meters and offers automated mowing with reliable performance. This model features the SensorCut system, which delivers seamless mowing results without visible stripes. It handles slopes of up to 25 percent and effectively navigates narrow passages, with a swiveling rear wheel that enhances maneuverability in small and compact gardens. The programmable assistant calculates an optimal mowing schedule based on user inputs, which can be adjusted as needed.

Safety is a priority with integrated lift and tilt sensors that immediately stop the blades when the mower is lifted or turned over, plus a large stop button for instant operation shutdown. The boundary wire reliably defines the mowing area, while sensitive collision sensors prevent obstacles from hindering operation. The mower automatically returns to its charging station after completing its tasks and can be secured against theft with PIN code protection and an alarm system.

It operates quietly and can be used in the rain. Maintenance includes easy cleaning with a garden hose, avoiding high-pressure cleaners, and checking for stones or sharp objects before use. The cutting height is adjustable from 20 to 50 millimeters. Its dimensions are 55 cm in length, 36 cm in width, and 22 cm in height, with a weight of 7.0 kg. It includes a lithium-ion battery with a capacity of 2.1 Ah and 18V voltage, takes about 60 minutes to charge, and provides up to 65 minutes of mowing time per charge. The monthly energy consumption is approximately 4 kWh. The package includes the lawn mower robot, the docking station, a connector, three connection pieces, 200 hooks, and 150 meters of boundary wire.
