  • the glide plate 108 is in a suspended, spring loaded mode. This will be described in more detail below in conjunction with Fig. 9 .
  • the glide plate 108 is configured to move, typically vertically, between different positions by influence of the vacuum force formed by air blown through the nozzle head 103 and counter acted by a spring.
  • a floating position can be formed where the glide plate is able to move between different positions.
  • the glide plate 108 can be suspended above the floor a few mm such as 2 - 5 mm or about 3 - 4 mm.
  • the vacuum force become greater than the force of the spring, and the spring-loaded glide plate 108 contacts the carpet for efficient cleaning of the carpet.
  • the smart mode will therefore act to provide efficient cleaning on different types of surfaces. This is due to the ability of the glide plate to move between different positions and also due to the forward brush being enabled to project through the glide plate.
  • the force of the spring will therefore be dimensioned in response to the vacuum force.
  • the spring force of the spring can be adapted to enable the glide plate to have different positions on different surfaces because the vacuum force will vary for different surfaces.
