No matter how connected it is, the Freelexo 1200 LCD BT robotic lawnmower still maintains a basic operating condition that moves randomly on the lawn and changes direction when it encounters an obstacle. The method may seem archaic, especially compared to the intelligent movements of robotic vacuum cleaners, but it is proven and corresponds well to a lawn mower.
In fact, the risk of seeing tracks on the lawn is reduced. And from experience we can say that it does not prevent the robotic lawnmower from covering the entire surface. It simply takes him longer, which is less disruptive as long as its operating noise is low and you usually do not spend as much time on your lawn as in your home. That said, of course, we can stop the mower at any time, as long as it can mow long enough during our absence.
Such a robot is also designed to mow every day to ensure an even result, with no visible difference in grass height from one part of the lawn to the other. While we remain convinced that the future of robotic lawnmowers also lies in smarter methodical navigation – if only to save energy – it is clear that a random mowing condition can ensure good results.
The robot must still be cunning enough to get out of complicated situations: narrow areas, narrow passages, depressions and bumps are all traps that only well-designed algorithms can handle effectively so as not to end up with a lawn mower constantly blocked or also using. much time in certain areas. In the present case, that is precisely what is wrong with this Freelexo, which has repeatedly found itself in a trap on our earth. The posts in the children’s cabin are certainly difficult, but most robotic lawnmowers that passed our test site manage to get out of them.
Similarly, due to a very low bumper that catches the smallest lump of grass that is a little too dense or stumbles if the mower rolls into a hole, many cutting interruptions occur. Freelexo then stops mowing, moving backwards, forwards again or changing direction, sometimes continuing until it stops, even though the lawn has already been mowed 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 bit of work to fill in gaps or cut harder around areas that are not necessarily annoying.
Also note that the edge mowing option does not solve this problem in any way, as the robotic lawnmower tends to cling to the grass that has just grown along the edges and is limited by the position center of its cutting disc, which inevitably leaves a good uncut width in the periphery. Fortunately, when it returns to its base to recharge, Freelexo runs along the left side of the perimeter cable (hence on the inside of the lawn), limiting the risk of immobilization with an empty battery.
This robotic lawnmower is too sensitive and we would have liked to have been more autonomous. Regrettable, because otherwise it ensures a work of good quality thanks to its small very sharp blades. However, its mowing width of 18 cm is not very large, and it is better not to have 1200 m² to pamper if you do not want the lawnmower to work night and day. However, Freelexo offers a good operating time / charging ratio, which ensures approximately 2 h 30 min mowing for a calculated charge of 1 h 45 min.
Its consumption remains reasonable at 0.07 kWh per. charging cycle. If it is used to the maximum of its capacity, it can thus ensure 5.6 cutting cycles per. 24 hours. Reduced to five complete cycles, it gives us a consumption of 0.35 kWh / day. In addition, the consumption of the base, measured at 2 W, when the mower is working (ie 0.025 kWh in five cycles) or waiting for its base when it is charged. Over a period from March to October (275 days), a total consumption of 103 kWh or around 18 € / year (tariff of 17.40 € / kWh) is calculated for Freelexo 1200 LCD BT.
