Reviews last updated: July 2026 · How we calculate this

What we like about BLACK+DECKER Flexi PD1420LP

  • Equipped with a highly flexible 1.5-metre integrated hose that easily reaches tight, awkward spaces
  • Lightweight and compact design makes it highly portable and comfortable to handle on stairs or in vehicles
  • Effective specialised pet hair tool that efficiently lifts stubborn hair from upholstery and couches
  • Strong and consistent suction power powered by a 14.4V lithium-ion battery system
  • Hygienic and effortless dirt disposal system using a quick-release side door mechanism
  • Reasonably fast eco-smart charging system that fully replenishes the battery in under 4 hours

What we don't like about BLACK+DECKER Flexi PD1420LP

  • Short overall battery runtime of approximately 11 to 15 minutes per full charge
  • Relatively noisy motor operation during high-performance cleaning sessions
  • Small dustbin capacity requiring frequent emptying when handling larger tasks
  • Suction power is limited to light-to-moderate messes and is not suitable for heavy-duty household vacuuming
  • Potential long-term durability issues with mechanical parts like the on/off switch jamming or casing hinges cracking over heavy use

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.
