Corded vacuum cleaner has more suction. It can absorb relatively heavy dirt. But it's wired, so it's not easy to use. Changing rooms requires a one-time plug change, and the wires are easier to wrap around and drag back and forth. Cordless vacuum cleaner suction is relatively small. The relative weight of the suction is light dirt, but it is convenient to use because it is wireless, wireless is not bound, you can use it freely.
Cordless vacuum cleaner OK. Usage: wired vacuum cleanerIt needs to be plugged in and used, and it needs to find sockets and power cords during use, while cordless vacuum cleaners can be used anytime and anywhere, and even leave the power supply for cleaning. This makes cordless vacuum cleaners more convenient and can easily clean different corners of the home. Cleaning effect: Wired vacuum cleaners are usually more powerful and can more thoroughly clean the floor, carpet and sofa and other household furniture.
Convenience: cordless vacuum cleaner is not bound by wires, and it is more convenient to use; Wired vacuum cleaners need to consider the length of the wire and the scope of use, which is relatively troublesome. Cleaning effect: The wired vacuum cleaner can always be powered, with stronger suction andLonger lasting cleaning capacity; Cordless vacuum cleaner battery power is weak, the suction generated is also weak.
Advantages and disadvantages of a wired vacuum cleaner The power of a wired vacuum cleaner is very stable, because it is powered directly by a wire power supply. Therefore, when people use a wired vacuum cleaner to suck dust, its suction is very stable, and the suction is strong, and there is no electricity halfway through the work, and there is no need to replace the battery. In addition, the dust box of the wired vacuum cleaner is very large, and dust debris does not need to be cleaned once in half an hour, and the cleaning interval is long.
Vacuum cleaner wireless good or wired good in general, I recommend that you buyA wired vacuum cleaner, because a cordless vacuum cleaner is not as good as a wired dust cleaner, that is the suction. The power of the wireless vacuum cleaner battery is limited, but also to control the horsepower output, like the wireless vacuum cleaner motor power can easily reach more than 1200 watts, the suction is two or three times stronger than the wireless, and the cleaning ability is much stronger.
To pay attention to the use of experience, the wireless vacuum cleaner is actually much better, the suction of the wireless vacuum cleaner is actually very good, not worse than the wired vacuum cleaner, the use of it will be a lot of flexibility. However, the shortcomings of the wireless vacuum cleaner are still obvious, and the battery life is oneA major defect, may not be enough to support the large house cleaning, daily light use is still no problem.
