most Dyson vacuum cleaners are not designed or intended to be used as blowers. Dyson vacuum cleaners are primarily designed to function as suction devices for cleaning floors, carpets, and other surfaces.
While some vacuum cleaners have a "blow" function or come with additional attachments that can be used for blowing air, Dyson vacuum cleaners, in general, do not have this feature. They are not equipped with a blower function, and attempting to use them as blowers could potentially damage the unit or void the warranty.
If you need a blower function for tasks such as cleaning leaves or dust from outdoor areas, consider using a purpose-built blower or leaf blower. These devices are specifically designed to handle blowing tasks efficiently and safely. Using a vacuum cleaner as a blower can be ineffective and may cause damage to the unit, so it is not recommended. Always refer to the user manual and manufacturer's guidelines for the proper and safe use of your vacuum cleaner.
