THREE IN ONE CLEANING: Vacuum, wash and dry at the same time! No need to vacuum and then mop. The BISSELL CrossWave Cordless Max combines tasks, vacuuming and washing at the same time picking up wet and dry debris, so you save time with every clean. The 36V lithium-ion battery provides up to 30min of cordless cleaning power, so you can move throughout your home without being tied to an outlet. Combine floor cleaning chores with cordless freedom. The BISSELL CrossWave Cordless Max lets you switch from cleaning sealed hard floors to refreshing area rugs in an instant. It also features improved edge cleaning to clean messes along baseboards and in corners. Always clean with fresh solution. The clean tank dispenses water and solution, while dirty water is stored in a separate dirty water tank. So unlike mopping, only clean water and formula go on your floor. After cleaning, the CrossWave Cordless Max's self-cleaning cycle cleans the XL brush roll and inside the CrossWave. It flushes out dirt, hair and debris after each use. Conveniently store it, run the Self-Cleaning Cycle & charge it.
