Verdict

The Sealey CP20VAV is a portable, cordless 20V ash vacuum cleaner from the SV20 Series featuring a 150W motor that delivers a maximum vacuum pressure of 100mbar and an airflow of 36m³/hr. Key characteristics include a 15L drum capacity with quick-release clips, a 1m flexible metal-lined suction hose designed for safely handling fine debris and ash up to 40°C, a 35mm accessory diameter with a round aluminum nozzle, and a built-in top outlet that easily switches the unit into a blower. Main pros are its lightweight design at just 2.4kg, its effective HEPA filter with an inner metal mesh to prevent dust leakage, and its cross-compatibility with other SV20 series lithium-ion power tool batteries. However, notable cons include its standard configuration being sold as a "body only" unit, meaning the necessary 20V battery and mains charger must be purchased separately, and it is strictly limited to cleaning cooled debris under 40°C.

What customers like about Sealey CP20VAV?

  • Cordless and extremely lightweight design provides high portability and ease of movement.
  • Dual-function design easily switches to a blower mode via the top outlet.
  • HEPA filter with an inner metal mesh effectively blocks fine ash and dust leaks.
  • Generous 15-liter capacity tank features quick-release clips for rapid and straightforward emptying.
  • Flexible 1-meter metal-lined suction hose safely handles warm ash up to 40°C (100°F).
  • Part of the SV20 Series power tool platform, allowing users to share the same 20V battery across multiple tools to save on costs.

What customers dislike about Sealey CP20VAV?

  • Sold primarily as a 'body only' unit, requiring a separate purchase for the compatible 20V battery and mains charger if you do not already own SV20 tools.
  • The 1-meter (roughly 3.3 feet) metal hose is considered relatively short for reaching deep into larger setups or chimneys.
  • Restricted to cool or warm debris only, with strict warnings against vacuuming hot, glowing material or active soot.
  • A 150W motor delivers sufficient power for standard maintenance but can struggle with dense, tightly packed, or large debris pieces.
