Points to Pay Attention to When Purchasing a Vacuum Cleaner

With the big number of options that are available, when you’re looking for a vacuum cleaner, finding the one that best fits your needs might end up leaving you confused and frustrated, which is perfectly understandable. Do you go with a make that you trust, or do you decide on an "unknown" brand simply because it looks better on paper? To start you on your quest for YOUR perfect vacuum cleaner, let’s look at some of the features found on modern vacuum cleaners.

Cyclonic technology

Portable vacuum cleaners working on the cyclonic separation principle became popular in the 1990s. This dirt separation principle was well known and often used in central vacuum systems, but had not previously been widely applied to portable units.

Cyclonic cleaners do not use filtration bags. Instead, the dust is separated in a detachable cylindrical collection vessel or bin. Air and dust are sucked at high speed into the collection vessel at a direction tangential to the vessel wall, creating a fast-spinning vortex. The dust particles and other debris move to the outside of the vessel by centrifugal force, where they fall due to gravity. 

In fixed-installation central vacuum cleaners, the cleaned air may be exhausted directly outside without need for further filtration. A well-designed cyclonic filtration system does not lose suction power due to airflow restriction, until the collection vessel is almost full. This is in marked contrast to filter bag systems, which lose suction as pores in the filter become clogged as dirt and dust are collected. 

In portable cyclonic models, the cleaned air from the center of the vortex is expelled from the machine after passing through a number of successively finer filters at the top of the container. The first filter is intended to trap particles which could damage the subsequent filters that remove fine dust particles. The filters must regularly be cleaned or replaced to ensure that the machine continues to perform efficiently. 

Vacuum cleaner

Vacuum cleaner motor

The motor is the core component. The quality of the motor directly affects the working efficiency and service life of the vacuum cleaner. Usually, we can see whether the motor is good or not, and it depends on the vibration sound of the casing itself. 

Vacuum cleaner noise 

Because of the motor relationship, the vacuum cleaner will inevitably emit some noise when it is used. If the noise is particularly large, no one likes it. Try to choose a vacuum cleaner with a decibel value of less than 80 decibels! 

Vacuum cleaner battery

Battery power

When consumers buy vacuum cleaners, they pay more attention to battery life. The battery life depends on the battery type and capacity of the vacuum cleaner.

The vacuum cleaner batteries on the market are roughly divided into nickel-cadmium batteries, nickel-hydrogen batteries, and lithium batteries. At present, lithium batteries are the first choice for many brands. Most vacuum cleaners are powered by lithium batteries which are safe and secure. 


From the sealing performance, it can be seen that the quality of the vacuum cleaner is good, and the vacuum cleaner with good sealing is also more energy-saving, and the suction and noise are superior.
