  • a side brush assembly 170 is linearly movable in a lateral direction (a left and right direction) of a casing 110.
  • the side brush assembly 170 that is, the movable member 171 may be linearly movable in a direction parallel to a rotation shaft of a wheel constituting a moving device 140.
  • Other components constituting the side brush assembly 170 that is, a leg member 174 and a brush 172 including bristles 173 may be the same as those of the first embodiment.
  • a first driving member 155 for moving the movable member 171, a second driving member 156 of rotating the brush 172, and first and second switches 157 and 158 for controlling operations of the first driving member 155 may be the same as those of the first embodiment.
  • Fig. 9 is a bottom view illustrating operations of side brush assemblies of an automatic cleaner according to a fifth embodiment.
  • a side brush assembly 180 that is, a movable member 181 is linearly movable in a diagonal direction of a casing 110.
  • the movable member 181 may be linearly movable in a direction crossing a rotation shaft of a wheel constituting a moving device 140.
  • the casing 110 When the casing 110 has a circular shape, it may be difficult to clean an area located at approximately 45° about the center of the casing 110.
  • the movable member 181 Since a corner of a cleaning region is located at approximately 45° about the center of the casing 110, the movable member 181 is moved in a line inclined at about 45° from the rotation shaft of the wheel constituting the moving device 140, thereby effectively cleaning the corner.
  • a component constituting the side brush assembly 180 that is, a brush 182 including bristles 183 may be the same as that of the first embodiment.
  • a first driving member 155 for moving the movable member 181, a second driving member 156 of rotating the brush 182, and first and second switches 157 and 158 for controlling operations of the first driving member 155 may be the same as those of the first embodiment.
