Are vacuums AC or DC?
The motor is an important part of a vacuum cleaner, providing the suction power of the vacuum cleaner, and there are many different types of motors. The most common type of motor for vacuum cleaners is the universal motor, which runs on AC and DC power and has a high power-to-weight ratio, this allows for a compact, lightweight design that is easy to maneuver. The other type is the more commonly used brushless DC motors, which are more efficient than universal motors and produce less heat, which can effectively improve the life of the vacuum cleaner.
In short, whether a vacuum cleaner uses DC or AC power depends on the type of motor, and most vacuum cleaners on the market today use brushless DC motors, which are more efficient motors that can meet people’s daily cleaning needs.
