Verdict

The Hoover H-POWER 300 (HP321) is an 850 W corded, bagless cylinder vacuum cleaner that operates via single-cyclone technology and plugs into standard 220V power sources. Key characteristics include an extra-large 2-litre easy-empty dust container, a washable H13 HEPA filtration system designed to trap 99.9% of allergens, and a versatile layout featuring an All Floors Adaptive nozzle alongside a Mini Turbo brush for pet hair removal. Its main pros are a broad 11.5-metre cleaning radius, high energy efficiency consuming 34 kWh/annum, robust suction across both hard floors and carpets, and integrated silver-ion treatment to prevent bacterial growth inside the bin. However, notable cons include fixed power controls that prevent suction adjustment and a slightly elevated operational noise level reaching up to 76 dBA.
