Verdict

The Ovation HT690 is a bagless ash vacuum cleaner featuring an 800W low-noise motor, a 15-liter capacity canister, and dual filtration via a reusable cloth pre-filter and a HEPA filter designed to trap fine debris. Weighing 3.5 kg, this compact machine includes a 2.5-meter power cable, a 1-meter flexible hose, an aluminum tube tool, and a crevice nozzle specifically for cleaning fireplaces, log burners, and BBQs. Main pros include its lightweight build, quiet operation, reliable suction power, and effective dust confinement. However, notable cons are its relatively short hose and electrical cord lengths, along with a tendency for the filters to clog quickly when processing heavy amounts of fine ash.

What customers like about Ovation HT690?

  • Good value for money and reasonably priced
  • Surprisingly quiet operation compared to standard utility vacuums
  • Lightweight design makes it easy to lift and carry around
  • Effective at capturing very fine ash particles without leakage thanks to the HEPA filter
  • Saves household vacuums or shop vacs from being damaged by harsh ash debris
  • Compact form factor makes it easy to store away when not in use
  • Strong and sufficient suction power for cleaning fireplaces, log burners, and BBQs

What customers dislike about Ovation HT690?

  • Filter clogs up very quickly and easily, sometimes before the tank is even a quarter full
  • Requires frequent cleaning and maintenance of the internal filter to prevent loss of suction
  • The 2.5-meter power cable is considered too short by many users
  • The 1-meter flexible hose lacks sufficient reach for larger setups
  • Struggles to vacuum larger pieces of debris or charcoal lumps without blocking
  • Emptying the fine dust and ash from the bin can be a messy process
