The Vacuum That Doesn't Lose Suction

The DC07, said to be the first vacuum cleaner that doesn't lose suction, is already a success in Europe and is now available in the U.S. The DC07 maintains constant suction due to the company's patented Root8Cyclone™ technology, which is said to create an unprecedented amount of centrifugal force to effectively remove dirt, dust, pet hair, dust mites, pollen, and other particles from both short- and long-pile carpets as well as bare floors. The DC07 reportedly has double the suction of other vacuums after picking up just 10 oz of dust.

Industrial engineer and inventor James Dyson developed cyclone vacuum cleaner technology after his household vacuum cleaner failed to do its job. Root8Cyclone technology causes high volumes of air to spin extremely fast through several individual cyclones, creating 100,000 G of centrifugal force. Dirt and debris are subjected to this force and subsequently thrown to the outer edges of the plastic bin. Because the airflow is unobstructed, there's nothing to clog, so suction power remains constant, and the DC07 vacuum is able to remove even the finest dust particles.

Unlike with other bagless vacuums that rely on filters to hold back dust, the HEPA filter in DC07 reportedly never needs to be replaced. In addition, the Bactisafe™ screen traps and kills bacteria, mold, and other germs on contact. The Dyson also has a removable clear bin that allows the user to throw away accumulated dust and dirt without having to get anywhere near it. A trigger at the top of DC07's bin releases a trapdoor at the bottom, so it can be emptied quickly and hygienically. Dyson, Malmesbury, England,
