The cyclone type was first invented by Dyson. This design, which first uses a cyclone for separation and then dust collection and filtration, can reduce blockage, make the horizontal suction more durable and strong, and eliminate secondary pollution after air filtration.

However, it should be noted that not all vacuum cleaners with dust boxes can create cyclones to filter dust and gas. Part of the dust box space is narrow, and the airflow inside cannot form a cyclone, so it can only be filtered by a filter. This is not much different from the dust bag type, but it is to replace the bag with a plastic box.
The working principle diagram of a cyclone vacuum cleaner: uses the high-speed centrifugal force formed by the rotation of air in the dust collection bucket to separate dust and gas. The dust falls into the dust bin due to gravity, and the separated air is discharged through the motor protection filter and HEPA filter.
Although the use of plastic dust bins instead of dust bags reduces the consumption of subsequent dust bags, it does not fundamentally solve the problem of dust during dumping and cleaning. Most of the dust bins are made of transparent resin materials, so the unbearable hair and garbage inside are easily visible during cleaning. Moreover, the absence of dust bags does not mean that there are no consumed follow-up accessories, and the cost of HEPA filters still exists. Because HEPA filters are disposable items and cannot be thoroughly cleaned, the filtering effect of filters that can be washed with water is generally much worse.
2) Water filtration
The filtering effect of a water filter vacuum cleaner is the best of the three. However, there are gains and losses, and water filtration cleaning is also the most troublesome of the three. Every time you use it, you need to drain the water, and after using it, you also need to clean the water tank, otherwise it is easy to mold, smell, or even rust. It is indeed necessary to have a diligent master who is so difficult to serve.
Working principle diagram of a water filter vacuum cleaner: Using water as the filtering medium, dust and microorganisms are dissolved and locked in the water, and then further filtered through the filter. The air discharged in this way is often cleaner than when inhaled, so there is no need to worry about secondary pollution.
In addition, using water as a medium has high requirements for product design and motor water discharge protection, which is also the main reason for the uneven quality and price difference of water filtration in the market. If the budget is not large, it is recommended not to take risks. If you are a tycoon, you can pay attention to Rainbow, which combines a vacuum cleaner, mite remover, and air purifier to alleviate asthma and dust mite allergies.
What does it look like doesn't matter? Appearance is actually one of the functions
Don't think that the appearance association doesn't care about appearance, the appearance of a vacuum cleaner is also one of its functions. We classify them into the following categories based on the common styles on the market:
1 Horizontal
Horizontal is the most common type in Asian households, with a market share of up to 80% in Asia and Europe. The classification of dust bags and non dust bags was first based on horizontal vacuum cleaners. Its main advantages include large dust capacity, high suction, relatively cheap price, and easy storage.
Among foreign brands, the Miele S8 series is recommended for horizontal vacuum cleaners, which have excellent performance and low noise, but have higher prices and fewer shopping channels.

Among domestic brands, Laike VC-T3519-3 is also good, supporting dual use of flooring and carpet, and domestic after-sales service is also relatively convenient.

2 Vertical
Simply put, it is a product that integrates suction head and body, suitable for large-scale carpet cleaning. It is common in European and American markets, but also sold in the Chinese market. Compared with the horizontal position, there is no need to drag the body when using it, and there is even no need to bend when the height is appropriate, which is more convenient and labor-saving; The replacement of hoses by straight vacuum pipes also reduces energy loss along the way, making it more efficient to convert suction power into suction.
However, the disadvantage of standing is also quite obvious. The integrated design will limit the dust capacity, and now it is below 1L on the market, so cleaning work is more frequent. When choosing, it should also be noted that standing is closer to the human body, so the feeling of noise is also greater. Friends who are more concerned about this aspect recommend the Vorwerk VK150 made in Germany, which has super strong suction and first-class noise resistance. The motor has a lifespan of up to 15 years and is very durable. ▼ Vorwerk VK150
3 handheld
The lightweight handheld is very convenient to carry and use. Without the constraints of wires, it can move up and down to the ground, which has a good effect on the bed, keyboard appliances, bed sheets, clothing, and other items inside the car. However, due to body size limitations, it also frequently suffers from criticism such as low power and weak suction.
In handheld devices, Dyson undoubtedly holds a dominant position, and many brands also borrow Dyson's previous technology to continuously launch new products. The new DC62 not only has a cool and lightweight design, but also has suction comparable to a wired vacuum cleaner, making it easy to reach the sky and the earth.

4-cylinder type
The cylindrical vacuum cleaner was first used in commerce, mostly for cleaning companies, hotels, and office buildings, but in recent years it has also begun to enter ordinary households. Its characteristic is large capacity and can be used for both dry and wet purposes. If you have pets with poor hygiene habits at home, you can choose a cylindrical vacuum cleaner to handle mixed waste at once. However, compared to other types, there are not many brand choices for cylindrical vacuum cleaners, among which the more famous is the German Karcher.

5 sweeping robots
The biggest difference between robots and vacuum cleaners is intelligence and power. Without manual operation, you can run around the house with just one click, meeting your basic daily dust removal needs, which is why it is highly popular among young white-collar workers. However, in terms of power and suction, it is naturally at a lower level, unable to achieve high cleaning like a vacuum cleaner, and its range of activity is limited to the ground. So if you live in windy and sandy areas such as Beijing and Lanzhou, or have high cleaning requirements for your home, it is recommended to prioritize using a vacuum cleaner; If the budget is sufficient, you can purchase one as a supplement to daily cleaning.

Brand control is not unreasonable. Imported products are selected in Germany and the UK, and domestic products are also good

The industry threshold of vacuum cleaners itself is not high, as long as they can form negative pressure in the body, they can meet the basic requirements of vacuum cleaning. Therefore, there are numerous brands on the market, and prices are also getting lower and lower. However, the gap between these entry-level products and high-end products is very obvious, and neither the technological content nor the manufacturing process can be compared.
In terms of foreign brands, traditional home appliance manufacturers well-known to Chinese people, such as Philips, Electrolux, Panasonic, etc., have always had good sales and performed reasonably well. However, when it comes to recommending them, as German motor brainwashed fans, I naturally recommend Vorwerk and Miele, which can suppress noise well under the premise of strong suction, and the motor that can last for ten years without moving is truly heartwarming to me. In addition, the old British brand Dyson is unparalleled in both styling and innovation capabilities. Nowadays, many mid to high-end products' core technologies are borrowed from Dyson, and performance is naturally not a problem.
The advantages of foreign brands include not only higher technological content, but also reliable product related data. The rated power, suction power, vacuum efficiency and other data provided in the manual are relatively reliable, and the difference from actual use can be controlled at 10%, so you can rest assured when choosing a reference. However, the biggest drawback is that the price is relatively high. If it is not purchased through official channels, the warranty in China is also a headache.
