Verdict

The Polti Forzaspira SLIM SR90B is a 2-in-1 cordless stick and handheld vacuum cleaner powered by a 22.2V lithium-ion battery, delivering a runtime of up to 40 minutes on a 4.5-hour charge. It features a 100W motor, cyclonic suction technology with two speed settings, a 4-stage filtration system, a 0.5-liter bagless dust tank, and a motorized floor brush with soft nylon bristles. Main advantages include its ultra-lightweight 2.2 kg design, easy maneuverability for high surfaces, and a convenient self-standing vertical parking position. However, potential drawbacks include a long charging time relative to its operational runtime and limited suction depth for thick carpets or homes with multiple pets.
