GARDENA Sileno Robotic Lawn Mowers: A Review of Popular Models

GARDENA robotic lawn mowers are characterized by premium quality, developed through over 20 years of experience in the development and production of these machines. These devices boast high autonomy, precision, and reliability. Today, we present a comparative review of three popular models: the Life 750, City 500, and City 250. We'll explore their features and identify their commonalities and key differences.

Equipment

The delivery set of the GARDENA Sileno life 750, Sileno city 500 and Sileno city 250 robotic lawn mowers is basically the same and contains the following components:

1. The robot itself.
2. Charging station.
3. Charging station screws (4 pcs.)
4. Low voltage cable.
5. Loop wire with connectors.
6. Fixators (300 pcs. - life 750/200 pcs. - city 500 and 250).
7. Connectors (5 pcs.).
8. Hex key.
9. Measuring ruler.
10. Operating instructions.
11. Quick Start Guide.

Appearance

The GARDENA life 750, city 500, and 250 are similar in design and dimensions. The housing is made of high-quality plastic and is gray with turquoise accents. The top of the unit houses the LCD display and push-button control panel. It also features an on/off button.

Below is an orange "STOP" button. Under the cover itself is the mowing speed controller and the rating plate.

When looking at the back of a robotic lawn mower, we see the wheels, cutting mechanism and disc, a built-in carrying handle, as well as a block containing electrical components, a battery, and motors.

The design of GARDENA lawn mowing robots allows for the quick cleaning of the housing, rotating legs and wheels from accumulated dust, dirt and grass debris using a garden hose.

Technical specifications

Let's start by comparing the performance parameters of GARDENA robotic lawn mowers.

	Sileno life 750	Sileno city 500	Sileno city 250
Working area	750 m² ±20%	500 m² ±20%	250 m² ±20%
Battery type	Li-Ion
Opening hours	65 min.
Charging time	60 min.
Electricity consumption	4 kWh	4 kWh	2 kW*h
Mowing system	3 knives
Cutting height	20-50 mm
Working width	22 cm	16 cm	16 cm
Maximum tilt level	35%
boundary wire	200 m	150 m	150 m
Weight	7.3 kg
Noise level	58 dB(A)
Timer	+	+	+
Average price	$750	$650	$580

As we can see from the review, most of the technical specifications of the three models are identical. The main distinguishing characteristic is the area covered: the Sileno Life 750 model has the largest coverage—750 square meters (±20%), while the 250 model has the smallest—250 square meters (±20%).

There are also differences in energy consumption: the life 750 and City 500 consume 4 kWh, while the City 250 consumes slightly less at 2 kWh. The working width of the two models is the same, as is the length of the boundary wire (models 500 and 250), but the life 750 has the advantage in these respects.

The noise level of the devices during operation is only 58 dB(A), which is several times less than many similar lawn mowers from other manufacturers.

Functional capabilities

In terms of functionality, all three GARDENA robotic lawn mowers are identical. All models feature the CorridorCut function, which allows you to mow grass even in narrow passages and dead ends up to 60 centimeters wide. Upon reaching a dead end, the machine automatically reverses and begins moving in reverse.

The intelligent ice sensor can detect temperatures approaching freezing, suspending mowing to protect the lawn.

In addition, the lawn mowers have a SensorControl intelligent mowing function, which automatically adjusts the mowing time depending on the speed of lawn growth.

The spot and spiral mowing functions are ideal for working in hard-to-reach areas and performing labor-intensive work (for example, under a bench, under a trampoline, etc.).

You can set up the GARDENA robotic lawn mower using a dedicated programming assistant. It features an intuitive menu where you can enter the lawn size and the optimal mowing time. There's no need for complex calculations or programming. You can also change the mowing schedule if needed.

To limit the mowing area, install a boundary wire, which is included with all three models of the lawn mowers in question. The robot will mow only the designated areas, not exceeding the wire's boundaries. Highly sensitive anti-collision sensors ensure timely braking and avoidance of obstacles. Once the machine is lifted from the ground, the mulching blades will immediately stop rotating thanks to special built-in sensors, ensuring protection and preventing injury.

The charging station can be installed anywhere.

Let's sum it up

Advantages of GARDENA Sileno lawn mowers:

1. Attractive design.
2. The duration of one haircut cycle is up to 65 minutes.
3. Energy efficiency.
4. Practicality.
5. Environmentally friendly.
6. Safety of operation.
7. Intuitive menu.
8. PIN code request (anti-theft protection).
9. Low noise during operation.
10. Timer, delayed start.
11. Cleaning with water from a hose.
12. Mowing in narrow passages, dead-end areas.
13. Working in the rain.
14. Programming the haircut duration.
15. Adjusting the mowing speed.

In conclusion, we note that the most expensive robotic lawn mower is the GARDENA Sileno life 750, while the most affordable is the City 250. The price difference is largely determined by the size of the area being mowered; otherwise, there is no significant difference.

That concludes our review of Gardena robotic lawn mowers. Happy shopping, everyone!
