Verdict

The Qualtex Powersonic RL166 is a bagless 1200 W ash vacuum with a 20-litre metal tank, HEPA and fabric filtration, and a built-in blower. Its 3.8 kg body and 1.10 m hose make it compact for fireplace and barbecue cleanup, while the filters help retain fine ash. The 2.5 m cable and short hose limit reach, and it is intended for completely cooled ash.
