Why Choose the SILENO flex?
Boundary Wire Advantage
Unlike GPS-based robotic mowers—which are often costly and susceptible to signal issues—the SILENO flex utilizes boundary wires for dependable, consistent operation. While installation requires a one-time setup, it ensures precise mowing around edges, gardens, and tight spaces. We’ve trusted and sold boundary-wire systems for over a decade—because they work.
Precision Mowing Made Simple
Included boundary and guide wires allow you to clearly define your lawn’s layout, enabling the mower to handle intricate areas with accuracy. Narrow passages and distant zones are no problem, ensuring an even, professional-looking cut throughout.
App-Controlled Convenience
Easily manage your SILENO flex from up to 33 feet away using the GARDENA Bluetooth® App. Set schedules, monitor mower status, and receive smart recommendations based on your lawn's size and grass type. It’s lawn care, simplified.
Intuitive Onboard Controls
Prefer a hands-on approach? Adjust settings directly on the mower using the built-in interface. The ergonomic design and clear layout make height adjustment and key functions easy—no app required.
All-Weather, All-Lawn Capability
Rain or shine, the SILENO flex delivers. Its AllCut System is compatible with common U.S. grass types—like Tall Fescue, Bermuda, and Kentucky Bluegrass—and cuts reliably from 1 to 4 inches. Whether you prefer a closely manicured look or a thicker cut, you’re covered.
