Einhell Freelexo 1200 LCD BT test: coupled lawn mower with removable battery that is both durable and sensitive

No matter how connected, the Freelexo 1200 LCD BT robotic lawnmower still maintains a basic mode of operation, moving randomly on the grass and changing direction when it encounters an obstacle. The method may seem archaic, especially when compared to the clever movements of vacuum robots, but it has proven to be a good lawn mower.

In fact, the risk of traces appearing on the lawn is reduced. And from experience, we can say that this does not prevent the robotic lawnmower from covering the entire surface. It just takes more time, which is less annoying as the operating noise is low and you usually do not spend as much time on your lawn as at home. That said, we can obviously stop mowing at any time, as long as it can cut long enough during our absence.

Such a robot is also designed to mow daily to ensure a uniform result, with no visible difference in grass height from one part of the lawn to another. While we are convinced that the future of robotic lawn mowers is also in the smarter method of navigation – even if only for energy saving reasons – it is clear that a random cutting operation can ensure good results.

The robot must still be cunning enough to escape complex situations: narrow areas, narrow passages, cavities and bumps are traps that only well-designed algorithms can effectively manage, so as not to end up with a lawnmower constantly blocked or spending a lot of time in certain areas. In the present case, this is exactly the mistake with this Freelexo that has been repeatedly trapped in a trap on our earth. The poles of the hut are certainly difficult, but most of the robotic lawnmowers that passed in our test field manage to get out of them.

Similarly, due to a very low bumper that catches the slightest mass of grass that is more or less dense or stumbles if the mower rolls into a cavity, many cutting breaks occur. The Freelexo then stops mowing, moves backwards, forwards again or changes direction, sometimes insisting until it stops, even though the lawn has already been cut to a height of less than 50 mm. Adjusting the cutting height to the maximum (60 mm) does not change anything. Annoying, because it takes a little work to fill holes or cut more sharply around areas that are not necessarily annoying.

Also note that the cutting edge option does not solve this problem in any way, as the robotic lawnmower tends to cling to the grass that has just sprouted along the edges and is limited by the center position of the cutting disc which inevitably leaves a good resting width at the periphery. . Fortunately, when it returns to its base to recharge, Freelexo runs along the left side of the perimeter wire (hence the inside of the turf, therefore), reducing the risk of being stopped with an empty battery.

This robotic lawnmower is very sensitive and we would like it to be more autonomous. It’s unfortunate, because otherwise it ensures good quality work thanks to its small very sharp blades. The cutting width of 18 cm, however, is not very large, and it is better not to have 1200 m² for grooming if you do not want the mower to work day and night. However, Freelexo offers a good running time / charging time ratio, ensuring approximately 2 hours and 30 minutes of haircuts for a calculated charge of 1 hour and 45 minutes.

Its consumption remains reasonable at 0.07 kWh per charge cycle. Used to its full potential, it can deliver 5.6 cutting cycles per 24 hours. Reducing to five full cycles, this gives us a consumption of 0.35 kWh / day. To this is added the consumption of the base, which is measured at 2 W when the mower is running (ie 0.025 kWh for five cycles) or is waiting at its base as soon as it is charged. For a period from March to October (275 days), an estimated total consumption of 103 kWh or about € 18 / year (pricing € 17.40 / kWh) for the Freelexo 1200 LCD BT.
