The knowledge of how does a vacuum cleaner works will assist you in taking the right decision to purchase a cordless vacuum cleaner. The vacuum cleaner works due to the gradient of pressure created between the inside and outside of the cleaner.
How Does a Vacuum Cleaner Work?
The embedded motor inside the vacuum runs the fan that results in lower pressure compared to the ambient pressure that exists inside the house. This gradient of pressure forces outside air to feed into the vacuum hose. The dust and debris are also flown into the hose along with the high-speed air. When the dirt-mix-air reaches the bag/container, the air passes through the fine pore of the bag or filter leaving the dirt inside the bag/container. However, for the proper functioning of the vacuum, its’ individual part should work smoothly. The principal parts of a cordless vacuum cleaner are described below.
The Principal Parts of a Cordless Vacuum Cleaner
The motor is the energy house to run the vacuum. The motor runs the fan to create a vacuum inside the vacuum cleaner. The creation of this vacuum results in suction due to the pressure difference between the inside and outside of the vacuum. The position of the motor is normally at the top of the handle. However, some models place the motor near the middle of the stick even at down to the base in some models.
The handle is a very important portion of a cordless vacuum. Because almost all of the controlling switches and buttons are placed in this area. The convenience of running a cordless vacuum mostly depends on the wisdom in designing this part. Several important components of a cordless vacuum such as the motor, fan, filter and battery are assorted in this part of the vacuum. Therefore, this portion is the heaviest portion of a cordless vacuum. However, there are a few models that have relocated these parts to other portions of the vacuum to reduce the weight of the upper portion of the vacuum.
The filters play two important roles; i) prevent damage of vacuum interiors by the harmful debris and ii) pass the clean air retaining the dust and dirt inside the dust cup. Normally the cordless vacuum contains multiple filters to sort the dirt based on size. The larger sized debris is kept aside by a normal filter immediately after being sucked by the vacuum. The HEPA or HEPA type filters are inserted towards the final stage of the air to be passed away to ensure healthy air emission. Now, the cordless stick vacuum is in the market with amazing whole-machine filtration which contains several layers of filters to emit the air without any impurities. For, example Dyson V11 is built with six-layers filtration that captures 99.99% of the particles as small as 0.3 microns.
The cyclone, sometimes called cyclone technology, creates a radial force to fling the dust or clot of dust and dirt into the bin, thus prevent the filter from being clogged by the dirt. Therefore, the vacuum efficiency remains higher as there is no loss of suction. In some modern cordless vacuum, a number of attached cyclones increase the vacuum force. The Dyson V11, for example, is designed with 14 radial cyclones that create forces of 79,000g to fling the dust into the bin.
The wand is a long stick that allows you to clean the extended areas. You can clean the far-reaching places of the wall and roof as well as the hard-to-reach places under or back of the furniture. Besides, the wands are designed as such to fit the extra vacuum tools.
The vacuum heads are also called the vacuum tools or cleaning tools and this is the key part of the vacuum to perform the cleaning job. There are several types of vacuum tools that offer different types of conveniences during cleaning. The brush roles are suitable for carpet cleaning because the embedded semi-rigid bristles loosen the carpet to expose the dust and debris. The turbo head or powerhead in the modern vacuum cleaners is also convenient for cleaning the deep-rooted dirt in the carpet and rugs. The tools with soft foam roles are suitable for the hard floor.
The battery is the powerhouse for the cordless vacuum cleaner. The efficiency of a cordless vacuum principally depends on the battery run-time. The battery generally positioned near the motor. Several pieces of lithium or lithium-ion batteries are packed together, which is termed as six-cell or seven-cell batteries, to get the accumulated power during cleaning.
The bin or dust cup is the reserver where the picked up dust and dirt are stored during vacuuming. Normally the bin is attached near the cyclone before the exhaust filter. The cyclone technology flings the dirt inside the bin and helps to pass the air toward the HEPA or HEPA-like filters.
It is a very important accessory that transmits the power from the motor to the vacuum head. The belt rotates the vacuum head powered by a motor. So the smoothness of the belt has a great effect on vacuum performance. Therefore, you should check the belt frequently and do not be lazy to change the belt if you see the belt is malfunctioning. That way you can keep up your vacuum efficiency and unexpected damage of any vacuum part as well.
