Lacking the usual cumbersome cord and plug, the VC-NX1/VC-NXS1 canister vacuum cleaners make light work of cleaning. As major parts are at the center of the main unit, the VC-NX1/VC-NXS1 has a short turning radius, allowing it to smoothly climb stairs and weave around furniture and corners. Due to its vertically symmetrical shape, it can run upside down, relieving users from stressful situations in which the main unit is overturned by an obstacle. One of the main advantages of the "VC-NX" series is the high suction power of the motor. It has an ultra-high-speed rotation of 120,000rpm which is more than the jet engines of airplanes. Furthermore, since the body has a built-in large capacity lithium ion battery pack, it can be used up to 60 minutes without charging.
