The filter section protects something from the particle inflow of the vacuum pump part. The operating switch activates the cleaner body. In the dust collection tank, contaminant is saved. The handle part transports the cleaner body. The mount/demount device attaches or remove the head unit and dust collection tank. A lower part dust collection tank(140) communicated with the cleaner body observes the dirt amount of administration. It is formed into the transparent material which inside seen.
