Quiet operation, versatility and intelligent design characterise the GARDENA SILENO city 400 m² Robotic Lawnmower. The SILENO city is ideal for smaller lawns, combining high performance with convenient mowing. With the GARDENA Bluetooth® App, you can easily set the lawn size, select the mowing days and the desired start time on your phone. The Robotic Lawnmower will compile a mowing plan and is ready to go without any hassle. SILENO city can be conveniently controlled via Bluetooth® from up to 10 metres away. The Robotic Lawnmower calculates the required cutting time and the GARDENA Bluetooth® app with the scheduling assistant helps you keep your garden tidy. Thanks to its quiet motor, it has a class-leading noise level of only 57db(A). Neither you nor your neighbours will notice when the robot is working. The sophisticated CorridorCut guides the robotic lawnmower effortlessly through narrow passageways and tight turns, up to just 60cm wide. CorridorCut guides the robotic lawnmower out of even the trickiest dead-ends. With SensorControl, the robot can judge how often it needs to mow; and, precisely adjusted to the growth of the grass, it can set off at the best time. This clever little helper cuts the grass as efficiently as possible. The intrepid SILENO city works autonomously, regardless of the weather and terrain (Auto Weather and Terrain), come rain or shine. The clever robotic lawnmower detects when the ground is frozen or too icy and waits, pausing its program until the ground thaws. The boundary wire indicates to SILENO city which part of the garden needs mowing. And the guide wire guides the robotic lawnmower reliably and fully automatically through the work area. The mower has no problem in narrow spaces and always returns to the charging station. It mows completely autonomously, so you can spend more time doing the things you love in your garden. Slopes and inclines of up to 35 percent are no problem either. SILENO city is easy to clean with a hose; it doesn't get any easier than this. It's really easy to mow with SILENO city. Sit back, relax and let the mower do the hard work. You won't know how you ever managed without it! The intuitive GARDENA Bluetooth® app guides you through the installation. Your lawn always looks perfect with SILENO: THE intelligent robotic lawnmower. SILENO.
