What materials can be vacuumed with the ECHO® Shred ‘N’ Vac?

ECHO® Shred 'N' Vac models are designed to vacuum dry leaves, grass clippings, light garden debris, and small twigs up to 1/4" in diameter, and up to 3 inches long. Damp leaves can also be vacuumed, but if they are too wet, they may clog the suction pipe and may not shred completely. These units are not intended for materials such as gravel, rocks, pinecones, acorns, or mulch. For best results, ECHO® recommends first using the unit as a blower to clear away items that should not be vacuumed.
