The Gardena Smart Sileno Max 1500m² is an electric robotic lawn mower with a recommended coverage area of 1500 m² and a maximum lawn area capacity of 1800 m². It has a cutting width of 22 cm and comes with a dedicated smartphone app that supports remote control, connecting to devices via built-in Bluetooth rather than Wi-Fi, which it does not support. The unit weighs 10,300 g and measures 430 mm in width, 260 mm in height, and 630 mm in thickness, giving it a total volume of 70,434 cm³. Standard operating noise is rated at 58 dB, while eco mode reduces that figure to 50 dB.
The mower includes an obstacle sensor, a rain sensor, and a frost sensor, allowing it to adapt its behavior to changing weather conditions and operate in rain without issue. It supports scheduled mowing and returns to its base automatically via auto docking, while the mulching feature lets it process grass clippings directly on the lawn. The unit does not have a display, lacks anti-theft features, and is not compatible with Alexa or Google Assistant.
The mower handles slopes of up to 30% and covers a working area at a rate of 82 m²/h, with a mowing time of 50 minutes per session. Cutting height can be adjusted between 25 mm and 45 mm, with two available height settings to choose from.
The mower runs on an 18.5V system and draws 43.37W during operation. It features a removable battery that fully recharges in approximately 0.67 hours, making downtime between mowing sessions relatively brief.
