摘要

The inlet unit (110) has a main inlet body removably coupled to the inlet pipe of a vacuum cleaner via two connecting pipes (116,117). A contractible and extendable auxiliary inlet body is coupled to the main inlet body to variably cope with a corner of desired angle. The auxiliary inlet body has an auxiliary inlet port that communicates with the dust inlet port of the main inlet body.
