BISSELL? CrossWave? Cordless Max multi-surface cleaner combines cleaning tasks to let you vacuum and wash at the same time. Enjoy up to 30 minutes* of cordless cleaning power thanks to the 36V lithium-ion battery, so you can clean your home without being tied to an outlet. Plus, multi-surface cleaning capabilities let you switch from sealed hard floors to area rugs in an instant. CrossWave? Cordless Max multi-surface cleaner also features improved edge cleaning** for cleaning debris like pet hair along baseboards and in corners. Two-Tank Technology keeps clean and dirty water separate, so unlike mopping, only clean water and formula touch your floors. The self-cleaning cycle cleans the brush roll and inside of the machine after you're finished, so there s less clean-up after cleaning.
