Review of the cheapest robot lawnmower Worx LandXcape 600 LX790.

Worx Landroid S390 aka WR100SI costs 48,000 rubles, but it is almost impossible to find it on sale. There is a small chance that they remained in some OBI stores at the "old" price of 39,990 rubles.

In many ways, it is similar to the cheapest LandXcape LX790 robot mower, but there are several important differences.

Everywhere they write that the robot is designed for lawns of 390 m² (4 acres), the same figure is in the name "Landroid S390", but it has the same mowing parameters as LX790 (cutting width 18 cm, three knives), but it is impossible to install more than six acres for LX790, but here in the application it is set from 50 to 2500 m² (25 acres). Perhaps - the mowing area is just the length of the boundary wire in the kit and the number of pegs for attaching it.

Includes 130 meters of wire and 180 pegs, exactly the same charging base as the LX790 (even the signals are compatible - both robots "see" signal of any of the bases), power supply 20 V 1.5 A, pegs for attaching the base, two wire connectors, three spare sets of knives, instructions (there is no Russian, and the Russian instruction manual can be found on the Internet, but the Russian installation instructions do not seem to happens at all).

The disk with knives is shifted to the right side, thanks to which the robot mows almost to the edge of its body, in addition, the grass crushed by the front roller almost does not fall under the knives.

Behind the orange handle of the mechanical shutdown of the battery.

The rear wheels have a diameter of 20.5 cm, the front roller has a diameter of 7.5 cm.

Front, left and rear clearance is 5 cm, front right clearance 4 cm, rear ledge that reduces the clearance to 2.5 cm. This is done for greater safety (so that the robot cannot damage the hand of a small child lying in the grass).

On the body there is a large mechanical handle that raises and lowers the disk with knives (the clearance does not change), a large red STOP button, three control buttons and two indicators.

The robot supports Wi-Fi and the application, thanks to which there is the possibility of flexible settings, there are mowing zones (you can assign a zone and when mowing is selected in it, the robot will crawl along the wire until the start specified area and start mowing there), when stuck and other problems, push notifications are received, a work log is kept (you can see how long the robot mows, how much it charges), and statistics. From the application, you can stop the robot, but for some reason it is impossible to resume its work or send the robot to the base, although there are such buttons.

All differences between Worx Landroid S390 WR100SI and LandXcape 600 LX790:

- Wi-Fi and application;
- Ability to create mowing zones;
- There is a 10-hour mowing mode, triggered by buttons on the body (allows you to mow the entire lawn at a time after a long absence);
- Existence of the handle of physical shutdown of the accumulator;
- Disk with knives shifted to the right side (mowing at the edge, the front roller does not crush the grass before mowing);
- Small clearance on the right side;
- A metal bar for protecting knives, under which grass can be clogged;
- Less wire length (and fewer pegs) included.

There are more pluses than minuses. Despite the lower ground clearance, the robot's patency over an uneven area with bumps turned out to be quite decent, and a good algorithm anti-jamming allows the robot to simply bypass those metas where it cannot pass (then the robot will return there anyway, but on the other sides). After much deliberation, I decided to keep this particular robot for myself.
