Gardena Sileno Sense 400 Robotic Lawn Mower

Key features:

  • LONA™ Intelligence Technology
  • Wireless Navigation
  • Trim-to-Edge System
  • AI Object Recognition
See full description

  • Brushless

    1

    The advantage of brushless motors over brushed ones is that they do not have friction since there are no carbon brushes. Without carbon brushes, the motors are more efficient and have a longer lifespan as there is no wear (the carbon brushes in brushed motors wear out with use). They produce less noise, maintain constant torque at all speeds, do not overheat, and require no maintenance.

  • Maximum Coverage Area

    400

    Suitable for medium-sized private gardens, suburban homes, and country houses. Balance of size and functions for requirements with moderate area and few obstacles.

  • Connectivity

    Wi-Fi

    Allows remote control, scheduling, and monitoring via an app from anywhere with internet access.

  • Rain Sensor

    When the sensor detects rain, the machine stops and restarts when the grass is dry.

    1

  • Maximum Slope

    The maximum ground incline indicates the steepest slope (in %) that the robot can handle without any issues. Essential if your garden has uphill or downhill areas. The higher the percentage, the more capable it is on sloped terrains.

Description

Description

Enjoy a perfectly mowed lawn with the SILENO sense by GARDENA, which uses Vision AI technology for autonomous navigation without boundary wires.

At a glance

  • Wire-free: Easy installation via camera and satellite navigation for gardens up to 400 m².
  • LONA™ Tech: The robot learns, maps, and adapts to the specific features of your garden.
  • Safety: Detects and avoids solid objects while protecting your privacy.
  • EasyApp: Full control and zone management directly from your smartphone.

Smart Mapping and Autonomy

The smart SILENO sense revolutionizes lawn care with GARDENA's LONA™ Intelligence technology, which enables the robot to fully understand the geometry of your garden. Thanks to the use of Vision AI and satellite systems, it sets digital boundaries without the need for buried wires. The device automatically adjusts the mowing schedule based on weather conditions and grass growth, offering complete freedom.

Cutting Precision and Obstacle Detection

The Trim-to-Edge function of GARDENA ensures that the grass is cut precisely even in the most difficult spots, such as walls and fences. With the integrated camera, the robot immediately recognizes objects like stones or toys and avoids them, continuing its work over leaves or organic materials. The smart design with the blades at the back guarantees maximum safety for you and your pets.

Silent Operation and Durability

Designed to offer the ultimate user experience, the SILENO sense is one of the quietest in its category with Pro-silent technology. Its waterproof construction allows for easy cleaning with a garden hose, while its ability to operate on slopes of up to 25% ensures uniform results on any terrain. With the built-in SIM card, the connection remains free forever, keeping your robot always up to date.

Protection Certification

IPX5

Protection against low-pressure water jets from any direction.
Can be washed with a hose.
Rain Sensor
Yes

Rain Sensor

When the sensor detects rain, the machine stops and restarts when the grass is dry.
Obstacle Sensor
Yes

Obstacle Sensor

The sensors automatically detect objects or obstacles in the area, changing course without collision
Embedded GPS
No

Embedded GPS

Used for position tracking, smart route planning, or covering specific areas.
Noise Level
57 dB

Noise Level

The noise level indicates how loud the robotic lawn mower sounds during its operation. It is measured in dB(A) and affects comfort in the garden and neighborhood, especially in densely populated areas. The lower the rating, the quieter the operation.
Anti-theft Protection
No

Anti-theft Protection

Anti-theft protection in robotic lawn mowers safeguards against theft and unauthorized use. It may include features such as security PIN, audible alarm, GPS tracking, and app notifications. Ideal for open or unprotected areas, it offers extra security and peace of mind in use.
Weight
9.5 kg

Battery Specifications

Charging Duration
40 min

Charging Duration

The time it takes for the robotic lawn mower to fully charge its battery. The shorter it is, the sooner it returns to operation. Important for large or busy areas.

Cutting Features

Cutting Width
16 cm

Cutting Width

The cutting width indicates the width of the grass that is cut in each pass. The larger it is, the faster the area coverage, especially in large gardens.
Minimum Height Setting
25 mm

Minimum Height Setting

The lowest height at which the lawn can be mowed. Ideal for those who prefer shorter and well-maintained grass.
Maximum Cutting Height
45 mm

Maximum Cutting Height

The maximum cutting height that can be set. Useful for situations where you want to leave the grass taller, during hot seasons or for ground protection.
Maximum Ground Incline
25 %

Maximum Ground Incline: 25

The maximum ground incline indicates the steepest slope (in %) that the robot can handle without any issues. Essential if your garden has uphill or downhill areas. The higher the percentage, the more capable it is on sloped terrains.

Type of Boundary

GPS Boundary Setting
No

GPS Boundary Setting

They use GPS (or GPS RTK- Real Time Kinematic) to define the operating boundaries.
Cable (Perimeter Wire)
No

Cable (Perimeter Wire)

They use perimeter wire to define the cutting boundaries in the garden.
Sensor
Yes

Sensor

They feature built-in sensors (e.g. with ultrasound, cameras) for detecting the boundaries of the area.
LiDAR
No

LiDAR

LiDAR (Light Detection and Ranging) is an advanced sensor technology that uses lasers to "scan" the environment around the robotic machine. It creates an accurate map of obstacles, the path, and the surface, allowing for excellent navigation without the need for a boundary wire. Ideal for complex, open, or changing spaces.
