The Kärcher FCV 4 is a versatile 3-in-1 cleaning system designed to vacuum, mop, and dry hard floors and low-pile carpets in a single pass. Powered by a brushless motor and an 18 V lithium-ion battery, this device allows you to move freely throughout your home for up to 45 minutes, covering an area of approximately 200 m² on a single charge. The 3.2-inch Vision!Clean display keeps you informed, while the Dynamic!Control sensor automatically adjusts the cleaning mode to handle everything from light dust to stubborn dirt. Efficiency is driven by the Hygienic!Spin technology, which rotates the Pure!Roll® roller at up to 500 rpm to lift grime effectively. You can switch between specialized modes like Stair!Assist for tricky areas or Advanced!Power for deeper cleaning. The system manages water through a 750 ml fresh water tank and a 450 ml dirty water tank, ensuring a constant supply of clean liquid. Weighing 5.2 kg, the machine is balanced for easy maneuvering across your living spaces. Maintenance is simplified with the System!Clean self-cleaning function and a Duo!Pure two-stage filter system that captures particles efficiently. When you finish, the unit rests on its dedicated charging and parking station. The machine-washable roller can be cleaned at 60 °C, making it easy to keep the device hygienic over time. This setup is particularly useful for households with pets or those who frequently deal with liquid spills and daily debris.
