The Dyson V9 Submarine Extra is a cordless wet and dry stick vacuum that combines powerful suction with innovative wet cleaning technology. This lightweight vacuum weighs less than 5 pounds and delivers up to 40 minutes of fade-free suction powered by Dyson's Hyperdymium motor spinning at 120,000 RPM, generating 100 Air Watts of cleaning power.

The vacuum features dual cleaner heads for versatile cleaning. The Motorbar cleaner head deep cleans all floor types and automatically de-tangles hair with polycarbonate hair removal vanes that lift and spiral hair straight into the bin. The Submarine wet roller head uses a motorized microfibre roller to wash spills and stains from hard floors, continuously extracting dirt from the roller with each rotation to handle mealtime spills, hallway paw prints, and bathroom stains.

Advanced seven-cell lithium-ion battery provides up to 40 minutes of runtime across three power modes. Dyson's fully-sealed, five-stage filtration system captures 99.99% of microscopic particles as small as 0.3 microns, making it ideal for allergy sufferers and pet owners. The 11 cyclones capture and separate dust and debris without loss of suction. An intelligent LCD screen displays power modes, remaining run time, and maintenance alerts in real-time.

The vacuum includes eight specialized attachments: Motorbar cleaner head, Fluffy Optic cleaner head with LED lighting, Submarine wet roller head, hair screw tool, crevice tool, combination tool, and additional accessories. The hygienic point-and-shoot mechanism empties the 0.38-liter dust bin without hand contact. Water capacity of 10.14 ounces handles multiple cleaning tasks. The Costco exclusive V9 Submarine Extra package includes an additional wet cleaner head for extended wet cleaning capability.
