Several Technical Issues of Cordless Vacuum Cleaner are important to understand to buy an effective cordless vacuum. This is an engineered electronic device. Each of the parts of this device has a specific function, and the device performance depends on how accurately the parts are working. There are some low category brands in the market who design their products with lucrative appeals but do not function properly. Therefore, understanding the technical issues escape you to be tricked while purchasing a Cordless Vacuum Cleaner.
You can find a reliable list of the Best Cordless Vacuums for different categories.
The killer issues of cordless vacuum cleaner confuse a buyer
Does higher Wattage mean better suction of a Vacuum Cleaner?
The answer is NO. Most sellers highlight the wattage of the vacuum to draw the customers’ attention. Actually, wattage refers to the consumption of electric power by a vacuum motor per hour. Thus, 500W means the motor consumes 500W electricity in 1 hour. Low and high wattage motor will decide your energy cost rather than the vacuum efficiency. 100-200 wattage is enough for your cordless vacuum motor.
This is actually the power that works for cleaning. So, Output Power is a portion of Input Power that is used to create airflow and pass through the vacuum hose. It is expressed as Airwatt.
Suction and Airflow
These two parameters work together during running the vacuum. It is not possible to rate a vacuum using only one of them. You must check the Suction and Airflow before buying a cordless vacuum.
Suction refers to the power of a motor to lift water vertically through a 1″ column. The suction of a vacuum tells you the power of lifting or picking up the debris from the floor. Therefore, more suction means a higher ability to clean the deep down embedded dirt.
What does airflow do in a Cordless Vacuum Cleaner?
Airflow flows away the sucked or lifted debris to the container. This parameter you have to double-check because it determines how neatly the vacuum has cleaned your house. Literally, airflow defines the volume of air being flown in 1 minute.
Airflow is expressed as cubic feet per min (CFM). It is also expressed as liters per second. More airflow of the vacuum means a cleaner floor surface you will get. Typically, the airflow ranges between 25 to 35 CFM of the majority of vacuum models. But, there are a few brands who brought models with ultra-high airflow, for example, Dyson V10 offers you 50CFM airflow.
Factors Influence the Airflow and Suction of a Cordless Vacuum Cleaner
Some factors influence the airflow and suction of a vacuum cleaner. A high filtration system such as a HEPA filter or other advanced filter increases the resistance to airflow. Thus, the motor needs more power to exert the required suction. Besides, the properties of the bag, sealing of the bag, as well as the shape and diameter of the hose pipe regulate the suction and airflow rate.
Cyclonic Separation in a Cordless Vacuum Cleaner
Perfect filtration of dusty air is a major problem for vacuum cleaning. With time there is much improvement to get rid of this problem. The technology includes using the sealed bag, sealed filtration with a HEPA system etc. These technologies have improved customer satisfaction remarkably.
However, only using these technologies sometimes need to compromise the efficiency of the appliance. Filter blockage is a common problem for cleaning the dense dust and debris. A cyclonic separation system is an excellent use to minimize this problem. In this system, one or multiple cyclones work together to create a centrifugal force that separates the larger debris from the air. The larger particles are forced to separate into the bin and the air with mostly dust is passed to the filter. Thus, the load on the filter is greatly reduced.
