Clean off caked-on dirt and debris by pairing the BLACK+DECKER® 10L Water Bag accessory with the BLACK+DECKER® Cordless Power Cleaner [#BCPW350C1] (sold separately). Now you’re no longer tethered to a garden hose or reliant on a natural freshwater source. Fill and seal the water bag and take it with you so you have the freedom to use your BLACK+DECKER® Cordless Power Cleaner just about anywhere. When empty, the bag collapses and folds so it can be thrown into your backpack. This durable water bag will keep up with both your backyard activities and outdoor adventures.
