There's nowhere for grime to hide from the Shark Clean & Empty vacuum cleaner. PowerDetect Intelligence uses 5 deep cleaning technologies to spot and react to dirt. Your floors are noticeably cleaner, first time round. Its Reverse Clean Technology means it works as effectively going backwards as it does forwards. That means you get a faster, more efficient clean. The Auto-Empty Base charges and empties the vac whenever it's docked, so it's always ready for the next clean. Plus, the Anti-Allergen Complete Seal captures 99.9% of dust and allergens so they're not released back into the air.
