Garden vacuum cleaner
The garden vacuum cleaner is a portable appliance for blowing and vacuuming. It is capable of vacuuming leaves and similar light materials (even empty beer cans) which are deposited in a collection bag, or it can either be used to blow together leaves out of inaccessible corners and onto a tidy heap. Garden vacuum cleaners can either be powered by a turbine motor which guides air through a turbine wheel whereby the turbine wheel can be damaged by debris and wet garden rubbish can cause corrosion. Or by applying the injector principle: here the air does not come into contact with the turbine wheel and bulky material carried by the air cannot damage the turbine blades.
