Reviews last updated: July 2026 · How we calculate this

What we like about BLACK+DECKER PV1820L-QW

  • Strong and consistent suction power for effective surface cleaning
  • Innovative 200-degree pivoting nozzle easily reaches awkward angles and tight corners
  • Convenient integrated flip-out brush and extendable crevice tool eliminate loose parts
  • Compact, lightweight, and folds in half for streamlined storage and charging
  • Very easy to empty via the hygienic side door mechanism
  • Straightforward maintenance with a simple, washable filter system

What we don't like about BLACK+DECKER PV1820L-QW

  • Short battery runtime of approximately 10 to 15 minutes per charge
  • Noticeably loud and noisy during operation according to multiple users
  • Relatively long battery charging time of about 4 hours
  • Extendable nozzle mechanism can occasionally slip back inside during heavy use

Verdict

The BLACK+DECKER PV1820L-QW is a cordless 18V handheld vacuum cleaner featuring a patented 200-degree pivoting nozzle with 8 lockable positions, an integrated extendable crevice tool, and a flip-out upholstery brush. Weighing 1.38 kg and measuring 30.5 cm in length, it delivers a powerful 35 air watts of suction through an advanced high-performance motor and a 3-stage cyclonic action filtration system. Main advantages include its compact, foldable design for easy storage, an efficient Eco Smart charge system that fully replenishes the lithium-ion battery in under 4 hours, and a hygienic 0.44-liter side-empty dustbin that avoids contact with dirt. However, notable drawbacks include a relatively short runtime of just 10 to 13 minutes per charge, a loud operating noise level of approximately 84 to 85 decibels, and a battery that is not easily replaceable once it degrades.
