QV4 is the ideal model for those looking for a simple, economical and easy-to-use steam generator. The ABS body makes it the lightest and most compact model in the entire STI range.
Fast heating system. Thanks to the powerful heating elements inside the boiler, the machine takes a very short time to be ready to use.
Advantage: very short waiting times before starting work.
Steam adjustment. Thanks to this simple system it is possible to adjust the steam outlet.
Advantage: decrease or increase the steam flow depending on the surface to be treated and the specific need.
An intelligent boiler. Thanks to a pair of safety devices (a thermostat and an overpressure valve), the over- heating or over-pressure are managed autonomously by the machine.
Advantage: work in total safety.
Continuous and automatic water filling system in the boiler.
Advantage: the continuous refilling system does not require cooling, so you can refill the water tank at any time. This avoids unnecessary waiting and boring breaks that waste time.
