Each vacuum is 265x270x80mm (about 11x11x4 inches), weighs 1.5kg (about 3lbs) and can hold 180 milliliters (about 0.75 cups) of dirt. They can clean about 104 square feet (or about six Japanese tatami mat mats) per 30 minutes of runtime and can be set to do twice as much in a 60 minute cycle. Both units are now on sale in Japan for ¥14,800 (about US$111) each. Source: Livedoor News via Otakomu
