ABSTRACT:
There is provided a ceiling type air conditioner capable of controlling the operation of at least one of a moving unit for moving a brush assembly or a suctioning unit for suctioning foreign matters stored in the brush assembly based on the position of the brush assembly for collecting and storing the foreign matters filtered by a filter. Therefore, it is possible to properly control the movement of the brush assembly to effectively collect and store the foreign matters filtered by the filter. In addition, since a user does not have to exchange or clean the filter, it is possible to prevent inconvenience from being caused by exchanging or cleaning the filter and to prevent the filter from being contaminated.
