These cordless cleaners allow users to clean anywhere easily. The grip is designed to alleviate the burden on the wrist and arm of the user while the center of gravity is placed close to the wrist. As a result, the user can easily clean high places, spaces between and under furniture, and car interior. The DC motor with up to 110,000 rpm produces strong suction while the Vertical Tornado System maintains suction at >99%. The chassis has no dead space regardless of the optimized grip position and the weight balance. The main unit and the wand are slanted to reduce size and weight while improving performance and ease of use.
