For housewives to count the most annoying things of the day, "cleaning" must be on the list. Although it is not a lot of physical work, but the persistent cleaning day after day, year after year, still accumulates dust every day. Not only is there no sense of achievement, but the mood is often greatly reduced.
At this time, the advent of vacuum cleaners has undoubtedly brought a more efficient and easy cleaning method, and even lazy people are willing to turn on the cleaning mode. And for the various vacuum cleaners on the market, many people are in trouble again.
How to choose a vacuum cleaner? The problem is simple and complex.
The simple reason is that the vacuum cleaner is a small appliance, and the easiest way to choose is the highest configuration and the lowest price. The complexity lies in the fact that this industry is constantly changing every six months, from lithium batteries to motors to functional components, and new functions are developed one after another. Not to mention the constant innovation of the original brand, even brands from other industries have also played cross-border. There are so many types of brands, it is dazzling.
Everyone knows that Dyson is currently the most famous brand in the vacuum cleaner industry, and it is also the strongest in the entire vacuum cleaner industry in terms of performance. Their brushless digital motor can achieve 120,000 revolutions, while other brands have not yet approach steadily. If only from this point of view, Dyson is undoubtedly the strongest brand, and it should be sold at the highest price. But the high price is frustrating for ordinary consumers.
How to choose a cost-effective vacuum cleaner in a compromise, and give you some purchase reference.
Look at the suction power
Vacuum cleaners generally use a motor to drive the impeller to rotate at a high speed, so that a partial vacuum is formed in the dust collection chamber, and an air pressure difference is formed outside the dust collection chamber to generate airflow. The dust is sucked into the dust collection chamber together with the airflow, and after filtering, the dust is retained in the dust collection chamber and the clean air is discharged. The motor is the "heart" of the vacuum cleaner, and the quality of the motor directly affects the suction power of the product. Generally speaking, the higher the suction, the better, but the higher the suction, the better the cleaning power. A motor with excellent performance has three characteristics of high speed, low power and low noise. If you have no concept of power, it is best to watch the on-site vacuuming demonstration when you actually buy it offline, so that you can intuitively feel the suction power.
See filtration and purification performance
As a dust removal product, the quality of the filter system determines whether the dust will fly all over the sky and cause secondary pollution during use. Many vacuum cleaners will often have dust coming out of the air vents because of the poor airtightness of the body. If the inhaled dust is not filtered clean, the secondary pollution caused will become an invisible killer of home health. When purchasing a vacuum cleaner, take a good look at the vacuum cleaner row. Wind filter design. Generally, a good vacuum cleaner has several filter systems, so that the layers are intercepted and the air discharged is cleaner. There are also tornadoes with higher cleaning efficiency than ordinary vacuum cleaners, or dust rejection technology, which can also avoid secondary pollution.
The problem of air outlet filtration is also very important. The replaceable filter element in the vacuum cleaner is not easy to buy. The sponge filter element with certain washability and reuse is the mainstream choice for most vacuum cleaners. Some vacuum cleaners improve the structure of the dust collection box, so that the air forms a cyclone inside the vacuum cleaner, which can better separate dust and air, and ensure that the suction force of the vacuum cleaner is more durable through the principle of centrifugal force.
Look at the nozzle configuration and ease of use
Some household vacuum cleaners can only suck dry, or can they both vacuum and mop? The style of the nozzle, the weight of the body, and whether the body is thin or not, all affect the user experience. Generally, the more nozzles a vacuum cleaner is equipped with, the more complete the functions, the more ductile functions, and the more applicable occasions. Flexible enough suction heads can clean in multiple directions, such as brush heads for high places, low places, and corners, as well as brush heads for depilating clothing, removing mites, and sucking pet hair, all of which are quite practical. The actual needs of the individual to choose.
Look at the battery life
Cord vacuum cleaners are powerful and powerful, but they are also relatively bulky. Nowadays, there are generally portable and upright vacuum cleaners on the market. In order to enhance the flexibility of operation, they are all wireless designs. When choosing, the battery life of the machine cannot be ignored. The battery life is too weak. It is very cumbersome to use.
see details
The detailed design mainly looks at the appearance and comfort of the vacuum cleaner. Beautiful or not, everyone's aesthetics are different, as long as the owner likes it. The appearance mainly depends on whether the material of the vacuum cleaner shell is strong and durable. In addition, when purchasing, you should try whether it is easy to operate, and listen to the size of the noise. The national standard is 82 decibels, and you can use the mobile app to measure it.
Speaking of which, I have to boast about the vacuum cleaner industry benchmark - Dyson
In the 1970s, when the mainstream vacuum cleaner brand in the UK was Hoover, Dyson also used Hoover's vacuum cleaner to clean his house, but this "high-end" vacuum cleaner on the market gradually lost its suction power in his hands. As an engineer, Dyson wondered what the hell was going on.
In fact, in order to separate the air and dust of the vacuum cleaner, the inner dust bag will be covered with air holes. But with increasing use, these pores are gradually clogged like the drains of a running water tank. If the air cannot enter freely, the machine loses its suction power. Traditional vacuum cleaner brands regard this as an important way to make money, because there will be a lot of follow-up consumption, and it can also induce consumers to replace new models of vacuum cleaners, so no one with vested interests is willing to to solve this problem.
