The vacuum cleaner achieves the dust removal effect by forming a vacuum vortex through the high-speed rotation of the motor. Therefore, the motor is very important. The excellent vacuum cleaners on the market all use high-speed brushless motors, which have precise internal structures and stable performance. They are not only highly efficient, but also have a longer service life.

The suction power generated by the motor is the most intuitive parameter. The larger the number, the greater the suction force. The vacuum cleaner can suck in more dust and garbage, and the cleaning effect is better. Generally, a motor speed of more than 100,000 revolutions can meet the daily needs of the family. After all, there are not so many extreme situations. It is not advisable to blindly pursue high suction force, and the noise generated will also be very large, affecting the user experience.

Particles on the ground are easy to find every day, but small dust and floating hair are difficult to see with the naked eye. Especially for friends who like to do housework at night, visual cleaning is essential.

Green light dust display technology is the optimal solution for dust display technology in the vacuum cleaner industry. The human eye is more sensitive to green light with a wavelength of 555nm. When the dust and the ground are close in color, green light can make the dirt more prominent. It is the best dust display among all light sources and can help us clean the ground better without leaving dead corners.

White light dust display technology uses LED lights to illuminate dust. The light is emitted from the top of the vacuum cleaner brush head, with a short coverage distance. In addition, the LED light source is spherical light, with weak light and easy to disperse. When the floor color and dust are close, small debris and dust are not easy to be found, and can only slightly illuminate the surrounding environment of the floor brush.

Vacuum cleaners with lighting systems can make the dirt on the ground more obvious, and the effect is better.

The multi-purpose function of a vacuum cleaner depends on the brush head. In addition to cleaning the floor, different brush heads can be used to clean the balcony, bed, sofa, under the bed, window sills and other places. The more brush heads, the better, and the wider the application scenarios. In addition to the floor brush for daily cleaning, there is also the basic necessary mite removal brush head for cleaning beds and sofas; the two-in-one long flat suction can suck away all the dust in the gaps of window sills and sofas. With these, you can easily clean the whole house. Be careful when choosing a vacuum cleaner with less than three brush heads!

The filtration system is a very critical step in choosing a vacuum cleaner. Good filtration performance and dust absorption into the dust bin without dispersing can prevent secondary air pollution. This mainly depends on the filter layer. The more layers, the cleaner the filtration.

Secondly, it depends on whether there is cyclone technology. Cyclone technology can separate dust through centrifugal force, and dust will not clog the motor. The suction power will not be reduced after long-term use, and it can be completely released, so the cleaning effect of the vacuum cleaner will last longer.

● Battery life

Battery life is an important factor in cleaning appliances. The battery life of a vacuum cleaner has a great impact on the user experience. After all, no one likes to temporarily recharge the vacuum cleaner when cleaning halfway through the house. It is very troublesome.
Generally speaking, a battery life of 30 minutes or more is enough, which is suitable for a variety of house types!

● Noise

A vacuum cleaner is affected by the operation of the motor. The compressed wind force will inevitably produce noise. The lower the noise, the better. Otherwise, it will not only be uncomfortable for you to listen to it every time you use it, but also disturb your family and neighbors to rest. Normally, it should not exceed 90 decibels.
