Warrantied for business use, the Karcher SG 4/4 is perfect for a wide range of commercial cleaning applications in restaurants, pubs, schools or offices. With a 4 bar pressure rating & a large 4 litre tank capacity, the steam cleaner combines powerful steam application with an exceptional run time between refills, making it the ideal model for large cleaning jobs. Despite having such a large capacity, getting started is quick - the SG 4/4 only heats part of the overall volume of water at one time, saving you time & energy. You also won't need to wait for a new load of water to heat up if the tank becomes depleted; it's divided into two compartments, allowing you to top up as you go. Karcher's VapoHydro function gives users the control required to effectively adapt to different levels of dirt, providing infinite steam adjustment during operation. In the case of really stubborn, ingrained dirt, you can also use the SG 4/4's hot water jet function to dissolve caked on grime. Tested on Ent
