Primarily for clearing leaves, blower vacuums can also remove grass clippings and other types of garden debris. They generally come in two forms: electric and petrol. The latter tend to be more powerful, and are ideal for larger gardens. Petrol models are not cabled, so there is always complete freedom of movement. Their main disadvantage is extra noise over the electric models, which also switch easier between blower and vacuum modes.
Lyco sells a selection of blower vacuums, to suit professional or amateur use.
