Hoover
Description:

A vacuum cleaner is an electric household appliance for removing dirt by means of a vacuum. Inside the housing, a motor creates the necessary air flow, using a blower. This air flow, augmented with dirt particles, is lead through the suction pipe from the noozle to the interior of the hoover where it is subsequently filtered. For bagged vacuum cleaners, the filtration is performed by filtration bags which are permeable to air and therefore collect the dirt. Bagless vacuum cleaners, such as cyclone cleaners, create additional vortices. As a result of the centrifugal force, the dirt particles are pressed outward and then collected. For both hoover types, the alternating electric and magnetic fields at the fundamental frequency of 50 Hz resp. 60 Hz are caused by the motor.

Frequency ranges:
  • 50–60 Hz
  • 10–150 kHz
Type of field:
electric and magnetic
