When purchasing, you can choose the specifications of the vacuum cleaner from the structural shape, motor capacity and whether the functions used meet the actual use.
For families, it is more appropriate to use a vacuum cleaner of 400 to 600 watts, which is enough to remove dust from home carpets and other places.
When choosing a vacuum cleaner, you should first look at the shell of the vacuum cleaner.
If it is a plastic cylinder, check whether there are cracks in the cylinder, and also pay attention to whether the connection parts of the upper and lower cylinders are fastened. If it is a metal cylinder, first check whether the cylinder is bruised, whether the paint is uniform, and whether the upper and lower cylinders are sealed.
After checking the appearance, power on the vacuum cleaner, and there will be a sound of inhalation after power on.
When the hand blocks the suction port of the vacuum cleaner, the noise of the motor increases obviously. At this time, the hand will feel a huge suction force, and it will be very laborious to remove the hand.
It should be noted that the vacuum cleaner should only have the sound of wind after being electrified, and the smaller the sound of the whole machine, the better, and no other noise can be mixed;
Some vacuum cleaners are equipped with energy recovery devices. When selecting, you need to pull out all the power cords, and then press the take-up switch to see if all the power cords will be taken back.
Finally, the parts of the vacuum cleaner should be counted according to the instructions, and there should be no missing parts.
When choosing the quality of the vacuum cleaner first, we should consider the size of the vacuum cleaner itself.
If housing conditions permit, try to choose large ones with high unfair dust removal rate and relatively low noise;
Second, considering the power of the vacuum cleaner, you can generally choose 500~800W products, which can be mainly used to clean sofas, carpets, furniture and so on.
Choosing a suitable grade vacuum cleaner is mainly aimed at whether its use function can meet the requirements. If economic conditions permit, it is best to have a higher grade and complete functions as much as possible.
High-quality shell should be bright, plastic shell should be smooth, do not buy spray-painted products;
The filter screen with good performance should be a double-layer screen with large mesh and fine mesh;
Power-on inspection shows that the starting speed of good quality products does not exceed 1 s, the vibration amplitude of the shell is small to the touch and the noise level is low. After power failure, the deceleration time before parking should be more than 5 seconds, and the parking process should be smooth.
Because it has something to do with vacuum cleaners ~ I found some forums about vacuum cleaners and looked at them. There is only one feeling-there are many gunmen.
Of course, I'm not ignorant, but I've talked a lot and I don't understand.
I really can't help it, it's just that I'm free these days. Let's talk about some knowledge of vacuum cleaners first.
Write whatever comes to mind. It may be messy, but I hope you can include it.
Before it's too late, let's start: 1. The function of vacuum cleaner: First, when you buy a vacuum cleaner, you should know what it does and what it can do.
There is no doubt that a vacuum cleaner is used for vacuuming.
Cleaning up the dust falling from the corner is its specialty.
However, the vacuum cleaner is still suitable for cleaning floating dust, and the effect of the vacuum cleaner is not as good as that of mop for wet surfaces or dirt attached to the surface of objects.
Yes, there are even vendors who bundle vacuum cleaners and mops.
A vacuum cleaner with a roller brush is more suitable for cleaning the dust on the carpet.
Actually, I think this is the advantage of vacuum cleaner.
There may be less carpets in China, so the sales of vacuum cleaners are far less than those abroad.
Some export products are both wet and dry (suitable for kitchens), with high power and air volume, such as Emerson's C300X series.
2. Brand and OEM of vacuum cleaner.
More than 70% vacuum cleaners in the world are made in China, while more than 70% vacuum cleaners in China are made in Suzhou.
Brands sold in China, such as E-LUX, Haier, Philips, Sanyo, etc. And brands sold abroad, such as Hoover, Royal, Europa and Wal-Mart. Most of their products are OEM in Suzhou.
In addition, there are also enterprises in Zhejiang and Guangdong, which are not as large as Suzhou, but they are developing rapidly.
But pay attention to one thing: More than 70% vacuum cleaners produced in China are exported. In fact, the domestic vacuum cleaner market has just started.
It can be said that domestic manufacturers can make the best products, but the best products are not sold in China, and most of them are sold to Japan, Europe and America.
Of course, as far as we know, some domestic manufacturers have begun to buy some domestic sales rights of vacuum cleaners that were originally sold to Japan and the United States.
Domestic manufacturers have a large capacity, with a maximum annual output of 1000W units.
As for the proportion of domestic sales and export, from the order point of view, foreign orders are mostly thousands to hundreds of thousands/batch, and domestic orders of 2000/ batch are considered as large orders.
3. Important indicators of vacuum cleaners Generally speaking, vacuum cleaners at home and abroad have an important indicator: power.
But as far as power consumption is concerned, it means nothing except the size of power consumption.
