However, the current filter used to absorb the dirt inside the fish tank has shortcomings and cannot absorb the dirt when the water level is low (that is, through the bottom of the filter). The reason is that the dirt particles at the bottom of the fish tank are easily sucked into the chamber where the water pump rotor works. The larger and harder particles in the dirt will damage the motor, causing abnormal noise, stalling and other faults of the motor, which will affect the life of the motor. At the same time, when the current filter is taken out for cleaning, that is, when the filter itself is cleaned, most of the dirt will flow back with the water, causing the problem of repeated water pollution.
