Definitions

  • the present invention relates more particularly to household vacuum cleaners of the broom type making it possible to suck up dust and waste present on a surface to be cleaned, which may for example be tiling, parquet, laminate, carpeting or a rug.
  • the present invention aims to remedy these drawbacks.
  • the technical problem underlying the invention consists in particular in providing a vacuum cleaner which is simple in structure, economical and reliable, while having high cleaning performance.
  • the grip handle has a distal end portion equipped with a secondary suction head which is removably attached to the vacuum cleaner housing and which is fluidly connected to the suction motor when the secondary suction head is attached to the vacuum cleaner housing and when the secondary suction head is separated from the vacuum cleaner housing, the secondary suction head being configured to be fluidically connected to the main suction head, for example in a sealed manner, when the head secondary suction head is attached to the vacuum cleaner housing and being configured to clean surfaces when the secondary vacuum head is separated from the vacuum cleaner housing.
  • Such a configuration of the vacuum cleaner according to the present invention allows a user to separate the secondary suction head from the vacuum cleaner housing (and therefore to move the suction head away from the vacuum cleaner housing), and to then vacuum, with the secondary suction head, areas to be cleaned that are inaccessible by the main suction head (for example located at ceiling level or under low furniture).
  • the vacuum cleaner according to the present invention has high cleaning performance, while being simple in structure, economical and reliable.
  • the vacuum cleaner may further have one or more of the following features, taken alone or in combination.
  • the secondary suction head is configured to be stationary with respect to the vacuum cleaner housing when the secondary suction head is attached to the vacuum cleaner housing.
  • the secondary suction head has a lateral or transverse bulk smaller than the lateral or transverse bulk of the main suction head.
  • the main suction head comprises a sole provided with a lower face and with a suction cavity opening out on the lower face.
  • the vacuum cleaner comprises a locking member, such as a locking finger, movable, and for example pivotally mounted, between a locking position in which the locking member locks the head secondary suction head on the vacuum cleaner housing and prevents separation of the secondary suction head from the vacuum cleaner housing, and a release position in which the locking member releases the secondary suction head and allows separation from the secondary suction head of the vacuum cleaner housing.
  • the locking member is provided on an upper part of the vacuum cleaner housing. Such a locking member avoids inadvertent separation of the secondary suction head which could harm the use of the vacuum cleaner.
  • the secondary suction head comprises a locking element, such as a locking housing, configured to cooperate with the locking member when the locking member occupies the locking position .
  • the vacuum cleaner comprises a biasing member configured to bias the locking member towards the locking position.
  • the vacuum cleaner comprises a release member, such as a release button, configured to move the lock member to the release position.
