Third-party reviews

Based on ratings from across the web.
Reviews last updated: July 2026 · How we calculate this

What we like about BLACK+DECKER WDA315J

  • Lightweight and highly maneuverable design
  • Versatile wet and dry mess pickup capabilities
  • Easy to clean with a translucent, washable dirt bowl
  • Convenient wide-mouth opening for picking up larger debris
  • Ideal for quick pick-ups, small household tasks, and car cleaning
  • Includes a squeegee tool accessory specifically for liquid spills

What we don't like about BLACK+DECKER WDA315J

  • Short battery runtime lasting only 10 to 15 minutes per charge
  • Extremely long battery recharge time
  • Relatively noisy operation during use
  • Limited suction performance when dealing with deep carpets or embedded pet hair
  • Small overall dust bin capacity that requires frequent emptying
  • Occasional reports of fine dust leaking back out of the exhaust vents

Verdict

The BLACK+DECKER WDA315J is a cordless, bagless wet and dry handheld vacuum cleaner featuring a 10.8V lithium-ion battery (16.2 Wh) with a 1.5 Ah capacity that delivers 15 Air Watts of suction power. Weighing just 0.9 kg, it offers a 500 ml dry dust bowl capacity (reduced to 240 ml for liquids) paired with a specialized rubber lip nozzle and a washable, translucent dirt container for quick maintenance. Main advantages include its lightweight, ergonomic design, its convenient dual functionality for handling both solid debris and small liquid spills without changing tools, and a quick-release mechanism for hygienic emptying. However, its downsides are a relatively short runtime of just 10 minutes per charge and the lack of an integrated or onboard crevice tool, which can make tackling tight, hard-to-reach spaces more difficult.
