Verdict

The Dusty Bin DB21 is a compact, corded, bagless ash and dirt vacuum cleaner powered by a 600W motor and featuring a 4-litre capacity metal cylinder tank. Weighing between 1.7kg and 1.9kg, it is highly portable and comes equipped with a 2.5m power cable, a 0.5m flexible metal-lined hose, an aluminium bent wand, and a crevice tool. Its standout characteristic is a fire-resistant, washable HEPA filtration system capable of safely handling fine soot and ashes up to 55°C. Key pros include its extreme lightweight agility, convenient carry handle, and easy bagless maintenance. However, notable cons include its smaller 4L tank capacity requiring frequent emptying compared to larger workshop models, a short 0.5m hose length, and user reports that the motor and outer green casing can become quite hot during extended operation.

What customers like about Dusty Bin DB21?

  • Powerful suction from the 600W motor helps pick up fine ash and stubborn debris easily.
  • Extremely lightweight and portable design weighing under 2kg makes it effortless to maneuver.
  • Handles warm ash up to 55°C, eliminating the need to wait for fireplaces to cool completely.
  • Fire-resistant HEPA and fire-retardant filtration system effectively prevents fine dust from escaping into the room.
  • Bagless 4-liter metal cylinder tank is easy to open, empty, and maintain without replacement costs.
  • Reasonably priced and offers great value for dedicated log burner and BBQ maintenance.

What customers dislike about Dusty Bin DB21?

  • The internal filter tends to clog quickly with very fine ash, requiring frequent cleaning during a single session.
  • The motor and the green outer casing can get noticeably hot during extended operational periods.
  • The initial startup blasts out a strong rush of air from the exhaust, which can scatter loose, light ash if not positioned carefully.
  • The tank requires frequent emptying during larger cleanups due to its compact 4-liter capacity.
  • Corded operation limits physical movement to the reach of the power cable and short 0.5m hose.
