Overview
Senix builds this handheld blower around a four cycle engine that runs on straight gasoline, so there is no fuel mixing. An automatic compression release eases pull starts, and the engine can tilt in any direction without oil leaks.
Skipping the gas and oil mix is the reason to choose it over two stroke blowers, along with lower vibration on long jobs. Four cycle engines need oil changes, so maintenance shifts from mixing fuel to checking the crankcase.
Who it's for
Suited to yards, sidewalks and driveways where a cordless blower runs short. Large properties needing backpack power should look at bigger units.
Pros and cons
- No fuel mixing
- Easier pull start
- Works at any angle
- Dual grip handle
- Not sold in California
- Crankcase oil needs changing
- Heavier than cordless blowers
Performance notes
A full crank four cycle engine runs smoothly with low vibration, which helps on long cleanups. Airflow volume moves piles while air speed lifts stuck debris. All direction lubrication lets the user angle the blower freely.
