The VS4 is a compact and robust steam cleaner which offers outstanding power and sanitizing benefits. Optimal cleaning results are achieved thanks to 87 P.S.I. of steam pressure which helps remove dirt from hard-to-reach, close quarter areas. Continuously variable steam volume control and the VapoHydro function (continuous regulation of the water-steam ratio) means the machine can adapt perfectly to any cleaning task. The water tank can be refilled at any time, and when the water reaches the steam tank it rapidly heats up to ensure uninterrupted operation of the VS4.
