Electric pipe dredge, manual dredge, primary dredge and high-pressure sweeper are all very useful dredging tools. We can choose the right tools to use according to different needs and scenarios. For example, the electric pipe dredging machine has a good effect on the blockage caused by hard objects; Manual dredge is suitable for domestic water dredging; One-shot flushing of blocked sewer pipes by using the principle of high air pressure is particularly effective for dredging toilets. High-pressure cleaning vehicle is an advanced dredging tool at present, and high-pressure water jet is widely used to clean and dredge pipelines.
