This is cordless vacuum cleaner that uses a patented water filtration system to trap particles as small as 0.3 microns including dirt, dust, dust mites, pollen, and pet dander. Ideal for those with allergies or asthma, its motor is powered by a 18 1/2-volt battery and draws in dirt and dust into an internal water reservoir that traps the particulates and prevents them from reentering the home. With two modes and a bagless design that collects debris in a removable bin. The stick vacuum easily converts to a lightweight handheld unit in seconds, allowing use of the included two-in-one crevice tool and furniture brush. A full charge via its base provides up to 25 minutes of power. Charging base plugs into AC. 43 1/2" L x 10 1/2" W x 10 1/4" D. (8 lbs.)
