For over a century since its introduction to households worldwide, the vacuum has become an indispensable tool in removing dust and debris from places where an ordinary broom or mop could not. Vacuum cleaners may look like intricate machine with knobs and rotors of sorts, but they operate on the same basic pressure principles that enable a person to drink fluids from a straw.
Regardless of whatever type, a standard vacuum cleaner has six basic parts:
- An intake port where one can attach various cleaning attachments
- An exhaust port that allows air to escape
- An electric motor that provides the pressure
- A fan that provides the suctioning action and directs the dust where it should go
- A porous bag that filters the dirt that might otherwise escape into the exhaust port
- The housing that contains all the other electrical components that power the vacuum
Different variations on the ordinary vacuum have evolved, and one such model is the Wet and Dry Vacuum cleaner. This vacuum cleaner is for heavy-duty cleaning jobs, which is why many people use them. This vacuum cleaner can pick up liquid stains and solid dirt both at the same time. A conventional vacuum's porous cloth or paper filter might get wet, so this element was removed from the wet and dry vacuum. Instead of a dust bag, the wet and dry vacuum uses a bucket where dirt and water both settle.
This vacuum works using the following scheme:
Dirt is collected by a wide, usually sturdy plastic intake port.
The collected waste - both solid and liquid - are passed through a tube where a partial pressure is exhibited. This is an area where air flow is quickly taking up dirt for collection in the bucket.
Air flow slows down in the area over the bucket. The change in air flow causes the collected dirt to fall into the bucket.
- The slow air moving from the area above the bucket still passes through the fan, which is powered by the electric motor.
- After passing through the fan, air escapes though the exhaust port.
A wet and dry vacuum is an innovative design, as this does not involve exposure to dust allergens. These dust allergens cannot be avoided when emptying the dust bag of a typical vacuum. In this model, the dirt and the dust collected are dissolved in the water.
After cleaning, you simply have to dump the waste collected out of the bucket. Aside from this advantage, you do not have to replace the cloth or paper filters of an ordinary vacuum. With this model, you are assured that the air that passes out of the vacuum has very little dirt or dust in it.
