Determine the type of vacuum cleaner according to the clean environment
It's not like buying expensive products. The key to buying a vacuum cleaner is to choose the right kind according to the cleaning needs. As we all know, there are several kinds of vacuum cleaners, including horizontal vacuum cleaners, vertical vacuum cleaners, hand-held vacuum cleaners, and barrel vacuum cleaners.
Horizontal vacuum cleaner
Horizontal vacuum cleaner
At present, horizontal vacuum cleaners belong to a category with higher household usage in the Asia-Europe market. According to incomplete statistics, they account for more than 80% of the overall market. They are characterized by their small size and convenient storage. Horizontal vacuum cleaners have a wide range of applications. Carpets, interior cleaners, electric appliances, and home interiors are all the scope of their work. Therefore, if you want to use a multi-purpose machine, Xiaobian recommends that horizontal vacuum cleaners can be given priority.
Vertical vacuum cleaner
Vertical vacuum cleaner
Upright vacuum cleaners are common in the American market and are suitable for large areas of carpet cleaning. Therefore, for friends who lay carpets at home, Xiao Bian believes that vertical vacuum cleaners are a good choice.
Handheld vacuum cleaner
Handheld vacuum cleaner
One of the obvious advantages of hand-held vacuum cleaners is their compact size, easy to carry and use. Although compared with a horizontal vacuum cleaner, the power is relatively small, and the suction is “Svenâ€. However, in Xiaobian’s view, the handheld vacuum cleaner has been more than adequate for cleaning the interior of a car, keyboards, sofas, and electrical appliances.
Barrel vacuum cleaner
Barrel vacuum cleaner
From the barrel vacuum cleaner, we can find the shadow of the originator of vacuum cleaners a hundred years ago. Such vacuum cleaners are characterized by their large capacity and ability to absorb water, but their corresponding heads are also relatively large. They are generally used by cleaning companies, hotels, and office buildings. In the home environment, Xiao Bian is not recommended.
summary:
1, the pursuit of a multi-purpose friends, you can choose a horizontal vacuum cleaner;
2, multi-storey house ground, optional vertical vacuum cleaner;
3, for sofas, keyboards and other small gaps there is more furniture and electrical appliances, you can use handheld vacuum cleaners;
4, the company, office buildings and other large environments, non-barrel vacuum cleaner must be.
The process of selecting vacuum cleaners needs attention
See vacuum cleaner quality
To purchase a vacuum cleaner, choose a bright and smooth casing. Do not choose a paint product. For vacuum cleaners with good performance, the filter should be a double mesh with large mesh and fine mesh. During the power-on trial, the starting speed of a good quality product should not exceed 1 second. The amplitude of the housing should be small when the hand is touched, and the deceleration time should be longer than 5 seconds after the power is turned off. The stop process is even and uniform.
Watts and listening
In general, the wattage is directly proportional to the suction force. For the average family, a vacuum cleaner of about 1000W is sufficient.
One-button take-up function
After the vacuum cleaner is energized, only the sound of the wind should be heard. The sound of the whole machine should be as small as possible and should not be mixed with other noises. Some vacuum cleaners are equipped with a power recovery device. When selecting, the power cord must be completely pulled out, and then the wire take-up switch should be pressed to see if it will fully recover the power cord.
Dust bag or dust bag?
Vacuum cleaners are more and more criticized by consumers because of cleaning troubles and high cost of later use. The dust bag type vacuum cleaner relies on a bag or paper bag inside the vacuum cleaner to filter the inhaled dust-laden air, and the filtered dust is accumulated in the dust bag. If the dust bag is a cloth dust bag, it needs to periodically remove the dust bag to dump dust and clean the dust bag. However, it is easy to get dusty when you remove the dust bag and dump dust, and it is very troublesome to clean it.
The dustless bag vacuum cleaner is dusted by the filter element or the cyclone separation, and the dust falls into the dust box or the dust bucket. The direct dumping and washing can eliminate the troubles of cleaning the dust bag and purchasing the dust bag, and can also save a lot of money. Although the price of dustless bag vacuum cleaners is higher than that of dust bag vacuum cleaners, the price can reflect the technical content of the products to a certain extent, and dust bag type vacuum cleaners spend a lot of money in the later period. There is no secondary cost for the dust bag vacuum cleaners at a later stage, which makes the dust Bag vacuum cleaners are much less cost effective. Therefore, dustless bag vacuum cleaners are increasingly favored by consumers.
Summary of the article: As a good helper for household cleaning, vacuum cleaners have been highly praised by consumers for their excellent suction power. However, many consumers often have their choices influenced by a wide range of brands and prices. Therefore, Xiao Bian believes that buying expensive is not as good as choosing the right one. When we buy a vacuum cleaner, we must first clarify the use environment of the vacuum cleaner and then select the appropriate type of vacuum cleaner. For the selection of the product, it can also be based on the hardware details of the product and some The difficulty of cleaning is taken into account. Summary: In addition to the above points in the purchase process need to pay attention, whether with speed control function is also an important reference factor, speed can not only help you save electricity, but just start the head, with a minimum speed to boot To help protect the nose.

What is 5G CPE?
Definition of 5G CPE
CPE stands for Customer Premise Equipment. The so-called front end refers to the equipment in front of the customer's terminal equipment. When we use Wi-Fi, if the distance is far, or there are more rooms, it is easy to appear signal blind spots, resulting in mobile phones or ipads or computers can not receive Wi-Fi signals. The CPE can relay the Wi-Fi signal twice to extend the coverage of Wi-Fi.
What are the benefits of CPE?
Through the following comparison table, it is not difficult to understand the technical advantages of CPE products:
* Currently, the global 5G FWA service is mainly in the Sub-6GHz band, with only the United States and Italy supporting the millimeter wave band.
* 5G CPE integrates the low cost of Wi-Fi and the large bandwidth of 5G, combining the advantages of the two to form a strong complement to traditional fiber broadband.
The relationship between 5G, FWA and CPE
It can be said that FWA (Fixed Wireless Access) will be the most down-to-earth application of 5G technology. FWA business plays a key role in enabling "connecting the unconnected." FWA is a low-cost, easy-to-deploy flexible broadband solution. Compared with wired access technology, FWA has been an ideal choice for deploying broadband in many countries and regions because it does not need to obtain rights of way, dig trenches and bury cables, and drill holes through walls. The development of 5G technology is further promoting the development of FWA.
FWA services (including 4G and 5G) have reached 100 million users. FWA is no longer a niche service; The FWA industry as a whole has been supported by numerous suppliers. Why is that? In the 5G era, 5G CPE receives 5G signals from operator base stations and then converts them into Wi-Fi signals or wired signals to allow more local devices to get online. For operators, the initial user penetration rate of 5G is low, and the investment is difficult to realize quickly; The CPE business can use the idle network to increase revenue for operators, so major operators vigorously promote the development of 5G CPE.
FWA services can be used for both home (To C) and business (To B), and customers have different requirements for CPE devices when using FWA services in different application environments, resulting in consumer grade 5G CPE and industrial grade 5G CPE (similar to home routers and industrial routers).
In 2020, the global market size of 5G CPE will reach 3 million units, and it is expected that in the next five years, the market size of 5G CPE will maintain a compound growth rate of more than 100%, reaching 120 million units in 2025, with a market value of 60 billion yuan. As an important market for 5G CPE, China's 5G CPE market size will reach 1.5 million units in 2020 and is expected to reach 80 million units in 2025, with a market value of 27 billion yuan.
The difference between 5G CPE and other devices
CPE can support a large number of mobile terminals that access the Internet at the same time, and the device can be directly inserted with a SIM card to receive mobile signals. CPE can be widely used in rural areas, cities, hospitals, units, factories, communities and other wireless network access, can save the cost of laying wired networks.
A Router is a hardware device that connects two or more networks, acts as a gateway between networks, and is the main node device of the Internet. Routers use routes to determine the forwarding of data. If it is a home router, it does not support a SIM card slot, and can only receive signals by connecting to optical fiber or cable and then convert it into WI-FI to provide a certain number (several) of terminal devices to surf the Internet.
Industrial 5G CPE is equivalent to 5G industrial routers, and the technology of the two is not very different. On the one hand, the industrial 5G CPE converts 5G network signals into WiFi signals for transmission, and on the other hand, the data received by the WiFi network is converted into 5G network signals for uploading. In addition, industrial 5G CPE generally supports routing functions.
5G CPE trends
According to a research report, after evaluating the products of some mainstream 5G CPE suppliers, many institutions believe that the development of 5G CPE products will continue in two aspects: one is to support mmWave and Sub-6 GHz at the same time; Second, the design will pay attention to humanized operation and installation. The industry development trend will accelerate the demand for 5G in the medical, education and manufacturing industries due to the epidemic, and 5G FWA will promote global 5G CPE shipments.
