The GreenSweep does not use blades at all. A 15 amp motor spins heavy nylon cutting line at 9,000 RPM, and the line flails leaves and soft stems into fine mulch, the same principle as a string trimmer inside a drum. Because there is no steel edge, there is nothing to dull, and a stray stone or a bit of dirt does little damage.
Its 18:1 reduction ratio is respectable for leaves, which are mostly air. The tradeoff is that nylon line does not cut wood. It is the right machine for autumn leaves, garden stems and kitchen-garden waste, and the wrong one for a pile of prunings. Compared with the AIVOLT and the 60-liter unit in this guide, it gives up branch capacity completely.
Ownership consists of replacing nylon line when it wears short, which is cheap and tool-free on most designs. Keep leaves dry, feed steadily, and clean the drum of wet matter after use so it does not rot in storage. Load it with dry leaves in thin handfuls rather than a pile, and stop when the motor note drops. Check the drum after every session for wet clumps, since they cake against the walls and unbalance the rotor over time.
What works
- No blades to dull or sharpen
- Tolerates dirt and stones better
- 9,000 RPM motor shreds leaves finely
- Safer to clear than a blade chipper
Watch out for
- Cannot cut real branches
- Wet leaves clump and slow the line
- Line is a consumable to replace
