A vacuum cleaner, performing a cleaning operation using a nozzle casing coupled to a suction pipe or using the suction pipe free from the nozzle casing, is disclosed. This vacuum cleaner does not force a user to change an existing cleaning tool with another tool even when it is desired to clean a limited or narrow area that does not allow use of the nozzle casing during the cleaning operation. In this vacuum cleaner, the suction nozzle unit consists of a nozzle casing provided with a suction nozzle for sucking dust-laden air from a surface into the casing. This casing also has a mounting unit provided with a fitting bore communicating with the suction nozzle. A hollow cylindrical suction pipe is removably fitted into the fitting bore, with a dusting brush part formed along the lower edge thereof. A spring-biased locking bolt removably locks the position of the suction pipe within the mounting unit of the nozzle casing. A connection pipe is connected to the extension pipe of a cleaner body, while a connector is hinged to the domed end of the connection pipe so as to be tiltable relative to the connection pipe in a vertical direction. This connector also engages with the suction pipe while allowing the suction pipe to be horizontally rotatable in opposite directions.
