Verdict

The BLACK+DECKER Flexi PD1420LP is a 14.4V cordless handheld vacuum cleaner weighing 1.42 kg, equipped with a 20 air-watt high-performance motor, an integrated 1.5-meter flexible hose, a 500 ml bagless dust container, and a 3-stage cyclonic filtration system. Its main advantages include its lightweight and highly maneuverable design for hard-to-reach areas, a specialized pet hair removal tool, and Eco Smart charging technology that tops up the lithium-ion battery in under 4 hours. However, it is limited by a relatively short operational runtime of approximately 12.5 minutes per charge and a non-replaceable built-in battery.
