Charging station

The charging station has two tasks. It charges the Auto Mower’s battery when necessary, and also sends control signals along the search wire and boundary wires. The charging station is connected to a wall socket via the supplied cable and transformer.

Loop wires

Two separate loop wires have to be laid out, a boundary wire and a search wire. The boundary wire runs round the edge of the Auto Mower’s working area, and the search wire guides the Auto Mower to the charging station. Signals transmitted from these two wires are received by the Auto Mower’s sensor.

Auto Mower

Operating principle

The Auto Mower mows your lawn automatically. When its battery runs down it moves to its charging station to recharge. When the battery is fully charged, the Auto Mower starts mowing again.

The Auto Mower is controlled by a built-in computer that consists of a circuit board with a microprocessor. The computer is the Auto Mower’s “brain” and handles all of its functions, commands and path selection by means of the data gathered via the keypad, sensor and battery charging status.

Movement pattern

The Auto Mower always starts its work in accordance with the random principle, i.e. the starting path is unplanned. Each time it hits an obstacle or senses the signal from the boundary wire, the computer chooses a new direction. This is designed so that the Auto Mower never regularly repeats the same movement pattern.

If the Auto Mower enters an area where it senses that the grass is longer than where it has just been, it can start to mow systematically. It then mows in a spiral pattern, mowing the area that has longer grass than the sur- rounding area. After this it returns to the random principle.

Initially the Auto Mower works for a few hours to get an idea of the average length and thickness of the grass. Only then does it start working systematically.

When the front of the Auto Mower bumps into an obstacle it backs away and chooses a new direction.

When the Auto Mower needs to charge its battery it follows the search wire that leads it to the charging station. If the battery doesn’t need charging the Auto Mower ignores the search wire.

Working capacity

The Auto Mower can mow about 100 m2 per hour when it is working and is recommended for grass areas of up to approx. 1500 m2 ± 20%.

The size of the area that the Auto Mower can mow depends partly on the shape of the garden. If the working area consists of an open lawn, this generally means that the Auto Mower can mow a larger area than if the working area consists of several grass areas or one that has many trees, flower beds or the like.

The length of time the Auto Mower spends mowing and re- charging can vary, and depends partly on the temperature.
