Battery hard floor cleaner Karcher FC 4-4 Battery Set 4B Duo — cordless cleaner for sealed hard floors

The battery hard floor cleaner Karcher FC 4-4 Battery Set 4B Duo is a cordless cleaner designed for regular maintenance of sealed hard floors such as laminate, tile and sealed wood. The device combines rotating microfibre rollers with two cleaning modes to remove dust, hair and light spills efficiently while offering freedom of movement thanks to its battery operation and flexible joint.

Advantages

The FC 4-4 cleans by simultaneously sweeping and mopping with two rotating microfibre rollers, reducing the need for separate tools. Two selectable cleaning modes allow you to adjust roller rotation and moisture level to match different floor types and degrees of dirt. Built-in freshwater and wastewater tanks with indicators make refill and emptying straightforward, and the docking station provides convenient storage and recharging for the included exchangeable batteries.

Suitable for

• Sealed wooden floors and parquet
• Laminate floors
• Vinyl and linoleum
• Ceramic and glazed tiles (with appropriate rollers)

Key specifications

• Cordless operation with included exchangeable batteries and fast charger
• Two rotating microfibre rollers for sweeping and mopping
• Two cleaning modes (variable rotation and moisture)
• Freshwater tank capacity 400 ml
• Wastewater tank capacity 200 ml with full-tank indicator
• Flexible joint for easy maneuvering and docking station for storage

How to use

Charge the batteries in the docking station before first use. Fill the freshwater tank with water and, if desired, a suitable floor detergent according to the detergent instructions. Switch on the cleaner and select the appropriate cleaning mode for your floor type; move the appliance across the floor at a steady pace so the rotating rollers pick up dirt and moisture. Monitor the wastewater indicator and empty the wastewater tank when full. After use, rinse or replace the rollers as needed and place the device on the docking station for charging and storage.

Usage recommendations

Use the universal microfibre rollers for sealed wood, laminate and vinyl. For unglazed stone or rough tiles, fit the recommended stone rollers. Avoid using the cleaner on unsealed wood or heavily wet surfaces. Regularly empty the wastewater tank and clean the rollers to maintain performance.
