I use quite a lot of home vacuum cleaners. Cord vacuum cleaners and sweeping robots have gone a long way in vacuuming... The first to be eliminated is the very troublesome wired vacuum cleaner. Every time I suck out of range, I will be pulled by myself Lost power and trip over wires.

So it took a year to replace it. Then there is the sweeping robot, the infrared sensor will turn itself, but the disadvantage is that I still have to clear the edges and corners by myself, and I can't tell the pain. The last is the current Lake, which is not bad to use, it is much lighter than the previous two. I know that many vacuum cleaners need a wall-mounted pendant for charging and storage, but Lake is a new, handheld + vertical combination, just stand it up when not in use.

And the machine itself is not heavy, coupled with the low center of gravity design, it can be operated with one hand, there is a feeling of being driven by it, after cleaning the ground, Yijian switches to hand-held mode, and it is also very convenient to lift up to suck curtains or something. The sound of the real vacuum cleaner is not too loud, it is much better than the wired one I bought before, and it is quite comfortable to use.

The power of general upright vacuum cleaners is 400-1000W or higher.

The vertical vacuum cleaner can remove dust mainly because its "head" is equipped with an electric exhaust fan. There is a wind impeller on the rotating shaft of the exhaust fan. After the power is turned on, the exhaust fan will generate strong suction and pressure at a speed of 500 revolutions per second. The air in the fan is replenished, causing an instantaneous vacuum inside the vacuum cleaner to form a negative pressure with the outside atmospheric pressure; brushes, long pipes, elbows, hoses, and hose joints enter the dust filter bag, dust and other sundries stay in the dust filter bag, air After being purified by the filter, it is discharged from the tail of the body.

The vacuum cleaner is equipped with different parts to complete different cleaning tasks, such as floor brushes to clean the floor, flat brushes to clean sofa surfaces, sheets, curtains, etc., and small suction nozzles to remove dust and dust in small corners. Dirt in some household appliances.

Application areas of upright vacuum cleaners: carpets, cleaning in cars, electrical appliances, household appliances, etc.
