What is a good type of household vacuum cleaner

How to choose a household vacuum cleaner? Key points for purchasing household vacuum cleaners
1. Check the quality of the vacuum cleaner: the shell should be bright, the plastic shell should be smooth, and spray painted products should not be purchased; A high-performance filter should be a double-layer mesh with large and fine mesh; Power on inspection, the starting speed of high-quality products should not exceed 1 second, the amplitude of the casing should be small when touched by hand, and the noise level should be low. After power off, the deceleration time should be greater than 5 seconds before stopping, and the stopping process should be stable and uniform.
2. Look at the vacuum cleaner shell: When selecting a vacuum cleaner, you should first look at the vacuum cleaner shell. If it is a plastic cylinder, it is necessary to check whether there are cracks on the cylinder, and also pay attention to whether the connection parts between the upper and lower cylinders are tight. If it is a metal cylinder, it is necessary to first check whether the cylinder is damaged, whether the paint is uniform, and whether the upper and lower cylinders are sealed. After checking the appearance, turn on the vacuum cleaner and there will be a sound of suction when powered on. When using your hand to block the vacuum cleaner's suction port, the motor noise significantly increases. At this point, your hand will feel a huge suction force, and it will be very laborious to move it away.
3. Look at the wattage: Generally speaking, the higher the wattage, the stronger the suction. A typical household vacuum cleaner of 1000W is sufficient
4. Listen to the sound of the vacuum cleaner: After the vacuum cleaner is powered on, only the sound of wind should be heard. The lower the sound of the entire machine, the better, and there should be no other noise; Some vacuum cleaners are equipped with a power recovery device. When selecting, it is necessary to pull out all the power cords and then press the wire recovery switch to see if it has fully retracted the power cords. Finally, according to the user manual, check the accessories of the vacuum cleaner to ensure that there are no missing parts.
5. Is it convenient? Large wheels make it easier to move
6. Is there any speed regulation? The speed regulation function is to adjust the power of the machine head. When you need less suction, speed regulation can help you save electricity. Moreover, when starting the machine, use the minimum number of revolutions to protect the machine head.
