Zusammenfassung:	To keep an operable time of a vacuum cleaner to be operated with a secondary battery as a power source.SOLUTION: A cleaner 100 includes: an electric blower 41 for generating an air flow to suck dust; a secondary battery 44 for supplying drive power being the power to drive the electric blower 41; a secondary battery deterioration detection section 58 for detecting a battery deterioration degree being a degree of deterioration of the secondary battery 44; and a control section 57 and an electric blower drive section 51a for performing control to reduce drive power in response to a battery deterioration degree. The secondary battery deterioration detection section 58 calculates a capacity of the secondary battery 44 and detects a battery deterioration degree based on a change of the calculated capacity.SELECTED DRAWING: Figure 5 【課題】二次電池を電源として運転する電気掃除機が運転可能な時間を維持する。【解決手段】掃除機１００は、塵埃を吸い込むための気流を発生させる電動送風機４１と、電動送風機４１を駆動させるための電力である駆動電力を供給する二次電池４４と、二次電池４４の劣化の度合である電池劣化度合を検出する二次電池劣化検出部５８と、駆動電力を、電池劣化度合に応じて低減するように制御する制御部５７および電動送風機駆動部５１ａと、を備える。二次電池劣化検出部５８は、二次電池４４の容量を算出し、算出した容量の変化に基づいて電池劣化度合を検出する。【選択図】図５
