Overview
A 12 amp corded tool combining blower, vacuum and mulcher in one body, rated at 350 CFM and 210 MPH airflow with an 18:1 mulch ratio. It ships with one collection bag and switches modes without tools. A metal impeller handles the mulching.
The Trivac's case for itself is consolidation: one motor doing blowing, vacuuming and mulching instead of three separate tools, switched with a quick-release bag rather than a toolkit. Its 18:1 mulch ratio, driven by a metal impeller, means 18 bags of loose leaves can compact down to roughly one bag of mulch, the main space-saving argument over a blower-only model. It trades some raw airflow for that versatility, running at 350 CFM against the higher-CFM WG520 blower in the same WORX lineup.
- 350 CFM air volume
- 210 MPH airflow
- 18:1 mulch ratio
- Includes 1 collection bag
Who it's for
Anyone who wants to collect and mulch leaves for composting or disposal, not just move them off a driveway, is the target user. The narrow nozzle also reaches under patio furniture and low deck gaps for tight-space cleanup. Homeowners who only need to blow debris off hard surfaces would get more raw airflow from a blower-only model.
Pros and cons
- Switches between blow, vacuum and mulch, no tools
- 18:1 mulch ratio shrinks bag volume
- Metal impeller handles the mulching pass
- Narrow nozzle reaches under furniture and edges
- Lower airflow than WORX's blower-only WG520
- Only one collection bag included
- Corded, so range is cord-length limited
Performance notes
In blower mode the 12 amp motor delivers 350 CFM at up to 210 MPH from the nozzle; switching to vacuum mode routes debris through the same housing into the collection bag. A metal impeller inside handles the mulching pass, breaking down leaves at an 18:1 ratio as they enter the bag, so it fills more slowly than it would with loose leaves. The narrow nozzle shape is what lets it get under furniture and along tight edges a wider blower nozzle cannot reach.
