Verdict

The Redkey P8 is a cordless stick vacuum cleaner powered by a 250W brushless motor that delivers up to 25,000 Pa of suction across three adjustable modes (7 kPa, 13 kPa, and 25 kPa) via a built-in LED touch control screen. Key advantages include a lightweight 2.8 kg frame, an electric floor brush with integrated LED headlights, a 4-stage HEPA filtration system designed to trap 99.99% of microscopic dust particles down to 0.1 microns, and a removable 2200mAh lithium-ion battery. However, a major drawback is its limited battery runtime, which yields up to 40 minutes in Eco mode but drops drastically to only about 10 minutes when operating on maximum suction power.
