I didn't have to use the maximum suction power with this vacuum cleaner, I usually only use the 1st suction level for floors and hard surfaces, the 2nd level for carpets and car interiors, especially the long suction tube can be used with the 2nd level. Suction power level works in almost all hard-to-reach places in the house. The battery life is good and sufficient for daily cleaning, a higher capacity would be cool, but to limit the weight of the machine the current battery capacity is perfect for a handheld vacuum like this to run for over an hour. The attachments are also lightweight, but they are made from quality materials. A good cordless vacuum cleaner that will definitely come in handy.
