I'm considering buying a garden vac to clean up the leaves that fall into my garden from neighbours' trees. I have a 'low maintenance' garden with lots of gravel and crushed slate beds. I'm a bit concerned that the suction on a garden vac may be sufficiently strong to suck up this gravel and slate and then damage the shredding mechanism.
Any users of garden vacs out there like to advise me?
Uno-Hoo!
