- As with all hand-held machines, power to weight ratio is very important. High power combined with low weight means less time working, less vibration and less strain on wrists, arms and shoulders.
- Watch out for the changing system from blowing to suction - a good quality machine should be easy to switch.
- The shredding ratio with a blower-vac is important to consider. The smaller the pieces, the less space they take up in the collecting bag/container. Small pieces are also easily composted.
NB: See the article 'Moving Air - Specs' And Terms Used for our Garden Vacuums And Blowers' for more information on shredding ratios.
