What's the difference between a suction head and a vacuum cleaner suction head?

One vacuums and the other sucks water.

When using a vacuum cleaner to absorb water, you can adjust one or two gears, and you need to add clean water first. The amount of clean water is generally around 250ml.

The working principle of vacuum cleaner is that the motor drives the blades to rotate at high speed, which generates negative pressure in the sealed shell and sucks dust.
