The WHALL cordless stick vacuum features a high-efficient, 4-layer filtration system engineered to elevate whole-home cleanliness. Multi-stage filtering begins with durable pre-filters that catch larger particles, then routes airflow through a precision HEPA element that targets the smallest pollutants—removing up to 99.103% of dust for a fresher environment. This closed filtration path reduces recirculation and protects internal components, delivering steady performance on everyday messes, fine debris, and pet dander while helping maintain cleaner air in high-traffic living areas. Power meets endurance with an upgraded battery system built from six 2500mAh cells. Enjoy up to 45 minutes of maximum runtime for thorough sessions, or around 15 minutes in high gear when you need extra pull on stubborn messes. The detachable design supports independent charging and easy swaps to extend cleaning without downtime, while a full recharge completes in about five hours. Consistent suction, efficient energy use, and flexible charging make it ideal for quick touch-ups or whole-home cleans. Engineered for effortless control, the flexible floor head works within a 184° range as bright LEDs expose hidden debris under sofas, beds, and car seats. An upgraded V-shaped roller minimizes hair tangles for smooth, uninterrupted cleaning. The lightweight, cordless body includes a crevice tool and multifunctional brush heads, and the dust cup empties with a hygienic one-click release. A smart LED display shows battery level, suction mode, and alerts—air-duct blockage, ground-brush jam, or missing HEPA—plus three-gear suction selection for tailored performance.
