5 Handheld Vacuum Cleaners

Compact: Lightweight and fit comfortably in one hand.
Usage: Suitable for both home and on-the-go cleaning.
Variety: Corded or cordless options available.
Purpose: Clean confined spaces like car interiors, tables, stairs, and corners.

PROCEDURE
Unplug and Turn Off: Ensure your vacuum cleaner is unplugged and turned off.
1 Disassemble Relevant Parts: Disassemble the relevant parts according to your user manual. Keep any
screws or small parts in a safe place for reassembly later.
2 Remove the Old Part: Once you’ve identified the worn-out part, remove it from its position.
Tracing Wiring of Controls
A wiring diagram of a vacuum cleaner displays the motor, motor control, switch, and power supply wiring as well
as the wiring of other components, such as switches, sensors, fans, and control units. Each individual component
is typically drawn in black or white which will be used as a reference when connecting the parts. The respective
colors of the components correspond to the colors of the connectors.
Electronic Circuits in Vacuum Cleaners
A circuit diagram for a vacuum cleaner contains three major components: the motor, the power supply, and the
switch. The motor is responsible for powering the suction of the vacuum cleaner, and is connected to the power
supply and switch via wiring. The power supply provides power to the motor, and the switch controls when the
motor is on or off.
Result: Dismantling and identifying various parts, wiring, and tracing of various controls and electronic circuits in
vacuum cleaners is a complex process that requires a solid understanding of electronic terminology and symbols,
as well as the construction and operation of common electronic components.
