With the Bissell CrossWave Cordless Max and the hardwood floor brush roll, you can optimally clean sealed hardwood floors. It is effective and safe for both wet and dry messes on all sealed hardwood floors, allowing you to wipe up spilled water and dog food in the kitchen with just one device. The microfiber brush roll gently wipes away tough messes from your hard floors and sucks them into the machine. Once you've finished cleaning with your CrossWave Cordless Max, cleaning the hardwood floor brush roll is a breeze thanks to the self-cleaning feature of the CrossWave Cordless Max. In this process, the roll spins while you flush clean water through the machine, ensuring it gets cleaned and dries faster. Remember to replace your brush roll every 6 months to ensure your floors receive the best cleaning.
