摘要:
An air flow sensing unit, which may sense an amount of air flowing or an pressure for air flown into the cleaning apparatus by a suction motor or an impeller and inform a user of a time for emptying a dirt collecting receptacle of dust or dirt and/or a time for cleaning or replacing a filter with a new one, and a cleaning apparatus having the same are provided. The unit may include an air flow pipe to fluidly communicate an air flow passage of a cleaning apparatus with the outside, and an indicator positioned in the air flow pipe to be lifted based on a change in amount of air flowing or air pressure generated by air movement in the air flow passage and to be lowered due to a weight thereof.
