Combining a brushless dc motor with auto dust sensor technology, the airstorm is ewbank's most powerful and efficient cordless vacuum ever. The airstorm now comes equipped with a flexible tube that allows you to vacuum under furniture and clean other hard-to-reach areas around the home. An easily accessible button allows you to bend and straighten the tube as you clean, without having to manoeuvre or lift heavy furniture. In auto mode the airstorm uses sensors to detect the amount of dust and debris travelling through the tube and then automatically adjusts the amount of power required. The user can also manually cycle through 5 different power settings, and there is an led display control panel that provides an alert where there are blockages or required maintenance.
