Verdict

The Qlima ASZ 2020 is a compact 1000 W ash vacuum cleaner engineered for cleaning fireplaces, pellet stoves, and barbecues, featuring a 20-liter steel collection tank with a protective synthetic coating and an optimal suction pressure of 19 kPa. Key characteristics and pros include its dual vacuuming and blowing functionality, a fire-retardant and washable HEPA filter coupled with a protective metal wire mesh to trap 99.97% of fine dust particles, a flame-resistant 1-meter aluminum hose, and excellent mobility provided by four pivoting castor wheels alongside a 3-meter power cord. However, notable cons include a high noise output of 80 dB(A), a strict limitation to handling cold ash under 40°C, and a relatively short total reach of 4 meters that may restrict operational range without an extension cord.

  • Features a robust, heat-resistant metal canister with a large 20 to 25-liter capacity
  • Equipped with swivel caster wheels and a sturdy carrying handle for easy mobility
  • Includes a dual suction and blower function to easily clean hard-to-reach corners or stoke fires

What customers dislike about Qlima ASZ 2020?

  • Can be very noisy during operation, reaching sound levels around 78 to 80 dB
  • The HEPA filter requires frequent cleaning or tapping out to maintain optimal suction power during heavy use
  • The flexible suction hose length is relatively short (around 1 meter), limiting upward reach
  • Only safe for cold or slightly warm ashes (under 40°C), meaning it cannot handle hot embers safely
