Use of steam to tackle dirt: The Kärcher SC 2 Upright can clean any hard floor - even wood. With the preset, user-friendly two-step steam flow control, thorough cleaning using the Kärcher steam mop removes up to 99.999% of viruses* and 99.99% of all typical household bacteria** from hard surfaces. The steam mop heats up instantly and is immediately ready for use with a refillable and removable clean water tank, including a descaling cartridge. The device's operating status is indicated by color codes displayed on the LED lights on the handle. The combination is perfect: for even deeper cleaning and quick cloth changes without contact with dirt, Kärcher's floor cleaning cloths are attached to the EasyFix floor nozzle with a hook-and-loop fastener.
