1. Whether the suction is strong enough is the key factor affecting the vacuum cleaner. Whether it is a handheld vacuum cleaner or a wired floor vacuum cleaner, the motor determines the suction power of the vacuum cleaner. The motors used in vacuum cleaners on the market are roughly divided into two categories, one is ordinary brushed motors, and the other is Japanese NIDEC brushless motors. Brushless motors replace mechanical commutation with electronic commutation, which is technically superior to brushed motors. The carbon brushes of brushed motors are prone to wear and reduce the life of the motor. The life of brushless motors can be as long as more than 10 years. The most important thing is that the brushless motor can generate huge suction power. For example, the handheld vacuum cleaner P9 GTS under Taiwan Pusanick adopts the most advanced Japanese NIDEC motor, and the maximum suction power can reach 18500PA.

2. Is there a filter system

Anyone who has bought a vacuum cleaner probably has this experience. The vacuum cleaner just bought has a strong suction power, and it is also full of power when vacuuming, but after a long time, you will find that the suction power is far worse than when you just bought it, and then you will find that it is actually It's just that the filter is clogged with dust, you just need to clean the dust on the filter. In order to solve the problem of consumers frequently cleaning the filter screen, some brand manufacturers choose to add cyclone technology to the vacuum cleaner. When the cyclone is in operation, it can generate a strong centrifugal rate to separate the dust from the air, and throw the dust and impurities into the dust collection bucket. , and separate from the air to prevent dust from blocking the air outlet. For example, Taiwan's Pusanike P9 innovatively adopts an eight-cone cyclone energy-gathering structure to maintain strong suction for the vacuum cleaner at all times.

3. The size of the dust box

As the name suggests, the dust box is a container for storing dust and impurities. If the dust box is too small, we need to clean it more often. Maybe half of the house is cleaned, and the dust box needs to be cleaned several times. Over time, consumers will inevitably feel tired. Especially hand-held vacuum cleaners, although they are superior in size to floor vacuum cleaners, many people will take it for granted that the dust box will also become smaller. Therefore, we should also pay attention when purchasing, the larger capacity of the dust box, do not have to worry about the problem of clogging due to excessive impurities, it will be more worry-free.

4. Length of battery life

The length of battery life not only affects work efficiency but also affects user experience. The final analysis depends on the battery type and capacity. The batteries on the market are roughly divided into nickel-cadmium batteries, nickel-metal hydride batteries, and lithium batteries. The service life of different battery types is also different. Among them, the service life of lithium batteries is 3 times that of nickel-metal hydride batteries, and the service life is longer. also relatively high. Most vacuum cleaners on the market are powered by lithium batteries, which are safe and secure.
