FLOOR KING is a brushless multi-functional vacuum cleaner that combines vacuuming and mopping into a single appliance. FLOOR KING is powered by a replaceable 4.2V U-battery made by Litheli. The device's dual function is innovative and saves you a great deal of time and effort, liberating you from the tiresome routine of vacuuming first and mopping later. It is also multi-functional and comes with many accessories for specific uses. The mite removal head gives beds and sofas a deep clean; the crevice nozzle vacuums out dust hidden in narrow gaps, and the foot shape nozzle lets you clean all those hard-to-reach corners. The vacuum is very ergonomic and weighs only 1000g, making it very easy to use.
