Search method 2: Follow loop in
Automower runs irregularly until it reaches the
boundary wire. The mower then follows the boundary
wire in to the charging station.
This search method is best for an installation that has
an open lawn with wide passages (wider than about
3 metres) and no, or only a small, island.
The advantage of this search method is that the
search times are generally short.
The disadvantage is that tracks can be formed to a
certain extent in the grass behind the mower.
Problems can also arise if there are narrow passages
or a large number of islands, for example, bushes.
Automower may need to drive round an island up to
2 - 3 times, before it realises that it is an island and
drives on.
Search method 3: Follow guide wire
Automower runs irregularly until it reaches the guide
wire. The mower then follows the guide wire in to the
charging station.
The guide wire is an extra wire that is laid from the
charging station, out towards a remote part of the
working area or through a narrow passage and is
then connected to the boundary wire. For more
information, see 3.8 Installation of the guide wire on
page 34.
This search method is best for an installation that has
numerous or large islands, narrow passages or steep
slopes.
The advantage of this search method is that the search
times are generally short.
The disadvantage is that the mower can leave tracks in
the grass along the length of the guide wire.
