Lawn Area Coverage

GARDENA Sileno Life 750 Lawn Area Coverage

If you have a larger area of lawn, see further down for more suitable models of the Sileno Life range.


Max Incline

Inclines should pose no problems for this model. Unless you have a super-steep lawn it will efficiently tackle slopes and banks with ease. It can handle a maximum incline of 35%.


Charge Mow time

The GARDENA Sileno Life 750 takes only 60 minutes to fully recharge and will give you 65 minutes of mow time. When the battery is running low it will automatically return to the charging dock and continue mowing as and when necessary.


Cutting Heights

As the seasons shift and the weather conditions change you will probably want to change the cutting height on your lawn mower. You might have other specific reasons to adjust the cutting height. On the Sileno Life models a simple rotary dial on the top of the machine is all that is needed to make this adjustment. It takes a few seconds and no tools are needed. You can set the ideal height for your needs from 20mm to 50mm.

Navigation System

GARDENA Sileno Life 750 Power SystemThe GARDENA Sileno Life 750 robotic lawn mower operates in a random pattern. The mowing area is dictated by the boundary wires that you lay down on the initial set up. The random pattern might appear unusual at first but it is highly effective. The lawn mower is designed to mow the lawn regularly so before too long it will reach all parts of the lawn equally for a lush green carpet of lawn.

The collision sensor will ensure it navigates around obstacles in the garden. The mowing plan is established automatically when the system is set up but this can be manually adjusted if necessary.

Another benefit of the random navigation system, what GARDENA calls the SensorCut System, is that it does not leave stripes or lines on the lawn. The cuts will overlap for an even and neat cut. The navigation system is complemented by a sharp triple-blade system.


Power System

This GARDENA Sileno Life 750 is an 18V lawn mower and it comes with a 2.1Ah Li-Ion battery. Given the light design and intelligent navigation system combined with automatic recharging and regular mowing, this is more than enough to keep a 750m² area of lawn neat and tidy at all times.

Charging Station

The charging station is pretty easy to position and connect. What you need is an area near an electrical outlet that has a bit of space around it. It needs to be easily accessible so that the robotic lawn mower can make its way back to recharge when needed. The lawn mower needs to be able to reach and leave the station from all directions.


Blade

The blade is sharp and effective for a neat and easy cut. It consists of 3 blades connected to a disk. The blades can be sharpened and will need to be replaced after some time.


Control Panel & Setup

One of the many advantages of the GARDENA robotic lawn mowers is that they are easy to set up and user-friendly to operate. The instructions are pretty clear and there are videos available that will guide you through each aspect of the process.

Click here for GARDENA Robotic Mower Support Videos

You need to position the docking station and run and secure the boundary wires as well as the guide wire. Once that is done you need to start up the lawn mower. It has a clear display and easy to use control panel. A programming assistant will intuitively guide you through the process. Most of the operation is automated but can be changed if you wish.

When the GARDENA Sileno Life 750 mower starts it will survey the lawn and calibrate itself. Once you have confirmed this it is good to go. Start on the maximum height and lower it to the desired height after a few days.

Watch how it operates for a few days to ensure the boundary wire is setup up correctly and that the docking station is placed effectively. Make adjustments if necessary. Thereafter you can simply let the machine do its magic while you enjoy a beautiful lawn.


GARDENA Sileno Life 750 Mowing Features

Cut to Edge

GARDENA Sileno Life 750 Mowing Features How effectively the Sileno Life will mow to the edge will largely depend on how well the boundary wires are positioned. Unless you have grass height edging it is likely that some lawn edge will be left uncut no matter how perfectly the wires are placed. Expect a small edge may remain and a little trimming will be required.

Spot Cut

This range of robotic lawn mowers supports the spot cutting feature. This allows it to cut effectively in hard to reach areas such as under low trees or garden furniture. The spiral mowing action will address these challenging parts of the lawn.

Cutting Pattern

As mentioned above, it has a random pattern. This works well as the lawn mower operates regularly and will reach all areas equally over time for an even finish with no lines or stripes. You will have a neat lush lawn cut evenly in all areas.

Narrow Passage

Another advantage of this range is that they handle passages very well. Provided the boundary wires are set up correctly the compact and intelligent lawn mower should cope with all but the narrowest long passages with ease.

Multi-Zone

The Sileno Life range of robotic lawn mowers can operate in multi-zones. One would have to run a wire from one area to the next and use the device on Man mode.

The downside is that it will not recharge automatically so you will have to take it back to the docking station yourself. The GARDENA Sileno Life 750 instruction manual will give you more details on how to set it up for multi-zone operation.

Height Adjustment

Adjusting the height could not be easier. No need to haul out the tools, simply turn a rotary dial on the top of the lawn mower to adjust from 20mm to 50mm instantly.


Mulching

GARDENA Sileno Life 750 Mulching

There are many advantages to mulching and this GARDENA Sileno Life 750 lawn mower does it well. The grass is finely chopped and left on the surface of the lawn. Because it mows often this works effectively.

The first advantage is that you do not have to go behind and rake up the cut grass or spend time emptying a grass collector.

Secondly, the grass will slowly break down and enrich the soil with natural nutrients. This is good for the soil, free, and eco-friendly. The lawn will look better for it and you get to save time and money.


Rain Sensor

Sileno Life lawn mowers are quite happy to work in the rain so a rain sensor is not necessary. They will continue to mow unless you override the automatic settings.


App & Installation

There is an option to get this model with a smart Gateway. The GARDENA smart SILENO life Set (19113-28) includes the gateway.

The smart Gateway works with the Smart app to make the robotic lawn mower even easier to operate. The app is intuitive and user-friendly. It is available for iOS and Android. The app is free. You will need a Wi-Fi connection and a smartphone, tablet, or PC to operate it.

The GARDENA smart system is an integrated and networked system for a fully automatic garden and allows you to connect and control not just the robotic mower, but other systems around the garden such a watering/sprinkler and lighting  systems.


Safety Features

Lift & Tilt Sensors

GARDENA Sileno Life 750 Safety Features

GARDENA ensures their machines are safe to operate. The boundary wires ensure they stay where they should. They have a lift and tilt sensor that will safely stop the blade immediately when this happens. The collision sensor prevents it from having issues with obstacles on the lawn.

Quick-Stop Blade

If the GARDENA Sileno Life 750 is lifted or tilted, the quick-stop feature will stop the blade spinning immediately.

PIN & Alarm System

You want to ensure that your investment is safe and secure and only used by those authorised to do so. For protection it has a PIN code as well as an alarm.

Other options available

There are two other options in the GARDENA SILENO range available for smaller lawns.

Option 1

GARDENA Sileno City 300 Robotic Mower Sileno City 300 m² Set

Option 1 consists of the same robotic mower as we have just looked at, however, it comes with a range of handy extras. The specs are identical as it is the same model with the same battery. The setup equipment, in terms of wire and pegs, remains the same.

What you do get extra with this set is:

  • 9 x Blades and screws
  • 1 x Winter cable protection box
  • 1 x Maintenance and cleaning kit
  • 1 x Wheel brushes

For a small additional investment, you can get these extra items that will help to keep your mower in top condition. It will save you money buying this as a set rather than purchasing the additional parts separately. Not only will you be able to keep the lawnmower clean and well maintained but you will have spare blades on hand for when they are needed.

If you have a slightly larger area of lawn than this model will work better. It is ideal for small to medium gardens with a lawn area up to 500m sq. Again, the basic specifications, battery, and set up equipment are the same but due to the programming, it will work for longer periods allowing you to keep a slightly larger area neatly mowed at all times. Rather invest in this option if your lawn is between 300 and 500m sq.
