Verdict

The Kaminer 18L is a 1200 W ash vacuum with an 18-litre stainless-steel tank and washable HEPA and fabric filters. Its blower function and metal-reinforced hose make it useful for fireplaces and barbecues, while the dual filtration helps contain fine dust. The 2 m power lead limits reach, and fine ash requires regular filter cleaning; use it only with fully cooled ash.
