Whether a big area or small, mowing a lawn can be frustrating, especially when you don’t have the equipment to reach narrow spaces. That’s when choosing the right robotic mower is essential. The quality robotic mower will reduce most of your manual work while accessing all those tiny spaces your bulky mower failed to target.
So, which one should you go for? The classic LawnMaster or GARDENA? Both brands have built quite a reputation over time. But the question is, who will win the robotic mowers battle?
Let’s find the answer by comparing the two best robotic mowers of both brands: the LawnMaster L10 Robotic Mower and the GARDENA Sileno Life 750 Robotic Mower. While the former is designed for areas up to 400m², the latter can mow lawns up to 750m². Moreover, both products have almost similar height adjustment and blade quantity.
Let’s compare the two in greater detail to help you decide the winner. So, let’s get started!

LawnMaster Robotic Mower vs. GARDENA Robotic Mower: What’s the Difference?
LawnMaster and GARDENA both have been in the business for years. Today, both companies have multiple lawnmowers in their respective product lineups, but robotic mowers are the best products they offer. They are compact, easy to use, and do the job well to take the pressure off of you!
You may have already seen a significant price difference between LawnMaster L10 and GARDENA Sileno 75 from the table above. But what else? Let’s discover some distinguishing features of both.
Power System
The LawnMaster L10’s package comes with a charging station featuring a power cable of 10m. All you have to do is place the charging station anywhere where the mower can quickly return to. The cable is also long enough.
The LawnMaster L10’s 2.0Ah Li-Ion battery is located underneath the mower, next to the USB port, and it ensures an operating time of up to 10 hours a day.
On the other hand, we have GARDENA Sileno Life 750 with a 2.1Ah Li-Ion battery. The best part? This robotic mower automatically goes to its charging station whenever it needs to regain power.
Make sure to make the station accessible for the mower so it can easily reach it. The total charging time for the Sileno Life 750 is almost 60 minutes. With this robotic mower, you can mow your 750m² lawn for up to 65 minutes.
The LawnMaster clearly beats the GARDENA mower in terms of operating time. But, when it comes to coverage area, the GARDENA has the upper hand.

Navigation System
One exciting thing about the LawnMaster L10 is that you can adjust the mowing duration. The available options are four, six, eight, and ten hours, which suffice your daily mowing needs.
If you don’t want to mow daily, you can set the robotic mower for alternate days. Enter the PIN and press any of the four buttons longer than three seconds to turn on the alternate day feature. The navigation system is super easy in L10.
You can also set a specific boundary for your mower to prevent it from going outside your lawn. The package comes with 250 pegs and 150 meters of wire that lets you do so. Use the peg driver kit to establish your robotic mower’s perimeter quickly.
Typically, the LawnMaster L10 will operate within the border on its own, but you can start it manually too. The mower will automatically return to its charging station whenever it falls out of power. You just have to sit back and let the robot do all the work!
Meanwhile, the GARDENA Sileno Life 750 mows the lawn discretely. It allows the appliance to trim different parts of the yard equally. But, if you want to focus on a particular area, you’ll have to set the perimeter on your own. The process is the same as the LawnMaster L10.
You can adjust the mowing plan on the Sileno 75 on your own. The random navigation system of this mower is supported by collision sensors and SensorCut System. The sensor enables the device to move away from obstacles and continue mowing.
The SensorCut System ensures that no line stays behind on your lawn after the mowing is completed. This way, the GARDENA Sileno Life 750 gives you an even, neat yard.

Control Panel and Setup
The LawnMaster L10 is straightforward to set up. You just have to choose the mowing hours from the 4, 6, 8, and 10” buttons on the keypad, and you’re done. The mower has no app or additional software you need to download on your smartphone. This makes the process pretty straightforward.
However, for many lawnmowers, this is too old-fashioned, and the mower must come with an app to let them set the device from a distance. So, in this case, the LawnMaster L10 lacks. But it actually depends on personal preferences and expectations.
Comparatively, GARDENA robotic mowers have a lead here. They are also simple to set up, and you can control them via an app. You can enter your preferred mowing days, start time, and lawn size to let the device mow the lawn the best. Just secure the area with boundary wires, start the mower from its clear display, and allow the machine to calibrate itself.
Most of the functions on GARDENA Sileno Life 750 are automated, but you can change them manually anytime you want. The programming assistant on the mower will also guide you throughout the process.
Whether you have the LawnMaster L10 or GARDENA Sileno Life 750, you must observe how your robotic mower works for a few days. This will help you determine the right mowing hours and make necessary adjustments. After that, leave the machine on its own and see the magic!
Mowing Features
The LawnMaster L10 is a versatile robot mower that performs several functions for effective mowing. It won’t gather the clippings but will mulch them back into the lawn. This way, you will keep your lawn greener and healthier without worrying about emptying the mower’s collection bag.
There is a tie between the LawnMaster Robotic Mower and the GARDENA Robotic Mower for mowing features.
Like the GARDENA Sileno Life 750, the LawnMaster L10 also offers random cutting for lawns. Both robotic mowers can also mow sloped areas in your lawn, but the inclination shouldn’t be more than 35%.
Set perimeters for both robotic mowers to help them mow the right areas. This also allows both devices to handle narrow passages quite well. With the spot-cutting feature, the LawnMaster L10 and the GARDENA Sileno Life 750 can efficiently access hard-to-reach spaces, such as garden furniture and under areas of trees.
However, with GARDENA, you can operate the mower in multiple zones. You’ll have to pass a wire from one area to another and turn the Man mode on. The downside is that you will have to carry the mower back to the docking station.

Blades
The blade performances of the LawnMaster L10 and the GARDENA Robotic Mower are exceptional. Each mower features three quality razor-sharp blades that ensure a clean and neat cut. They also offer precise finishing.
However, you will occasionally have to sharpen the blades in both robotic mowers. If doing so doesn’t give you desired results, you should replace them after some time.
Height Adjustment
To ensure efficient cutting throughout the year, you must change your mower’s cutting height with the shift in the weather. The height adjustment for a LawnMaster L10 is between 20mm and 60mm, which is enough to keep a large lawn area well-maintained. But remember, it won’t be suitable for mowing longer grass.
Fortunately, the GARDENA Sileno Life 750 also offers a height adjustment feature. It ranges between 20mm to 50mm. You can adjust your ideal height by rotating the dial located at the machine’s top.
