The unit is engineered with DynamicControl dirt sensing technology that will automatically adjust the suction power and water flow depending on the dirtiness of the flooring. The system also features a VisionClean display for monitoring performance and to switch up cleaning modes. The unit is rated to cover 200-square-meters of living space in a single go thanks to a 45-minutes battery, while the [twin tank design](https://www.trendhunter.com/trends/dyson-clean-wash-hygiene) means it will only allow clean water to come into contact with flooring. The Kärcher FCV 4 has a brushless motor to maximize runtime and overall durability, and also features the HygienicSpin technology to remove up to 99% of bacteria from flooring.
