Choosing the right cleaning method is crucial for optimal results. In this article, we compare the two main methods of professional drain cleaning: hydromechanical and electromechanical cleaning.

Hydromechanical Cleaning (High-Pressure Jetting)

In hydromechanical cleaning, water is forced through special nozzles into the pipe at high pressure (up to 200 bar). This method is particularly effective against stubborn deposits, grease accumulations, and root intrusion. The water force loosens contamination and flushes it away simultaneously.

Electromechanical Cleaning (Spiral Cleaning)

This method uses flexible, machine-driven spirals with various attachments. It is particularly suitable for blockages caused by foreign objects and for cleaning connection pipes in buildings. The spiral mechanically breaks through the blockage.

When to Use Which Method?

High-pressure jetting is ideal for: main and ground pipes, stubborn deposits and incrustations, and preventive maintenance cleaning. Spiral cleaning is suitable for: toilet, kitchen, and bathroom connections, acute blockages from foreign objects, and hard-to-reach pipes.

Combination for Best Results

We often combine both methods for optimal results. For example, a blockage is first broken up with the spiral and then flushed with high pressure to remove all residue.

Our Recommendation

Trust the expertise of our technicians. They select the best method for your specific situation on-site and ensure thorough, material-friendly cleaning.
