What is an unblocking machine and what is it for?

Anyone who has ever faced a blockage at home, whether in the kitchen sink, toilet or any other pipe, knows how frustrating and inconvenient it can be to deal with this situation.

Clogs are common household problems that can occur at any time, and that’s where unclogging machines come into action to solve this nuisance.

Understand below how the unblocking machine can help with this unclogging process and much more.

The concept of Unblocking Machine

An unblocking machine is equipment specifically designed to unclog pipes, pipes and ducts that are blocked due to the accumulation of solid waste, grease, hair, toilet paper, tree roots or other foreign objects.

These clogs can occur in domestic, commercial and industrial environments and can vary in severity.

Unblocking machines are an indispensable tool for plumbing professionals and unclogging services, but they can also be used by homeowners to deal with smaller clogs on their own.

How does an unblocking machine work?

Unblocking machines use different methods to remove blockages in pipes. The two most common techniques are the use of unclogging cables and hydrojetting.

Unblocking Cables

This is the most traditional and widely used technique. An unblocking machine equipped with a flexible cable and a special tip is inserted into the blocked pipe.

The operator controls the machine to advance the cable into the pipeline while simultaneously rotating it.

The end of the handle is designed to break or push out blockages, allowing water to flow freely again. It is an effective technique for unclogging sinks, toilets and sewer pipes.


This technique involves using pressurized water to eliminate the blockage. The unblocking machine is equipped with a hose that is inserted into the pipe.

The water is then expelled at high pressure, which breaks up and removes blockages and cleans the inner walls of the pipe. Hydrojetting is especially effective for unclogging main pipes and sewer lines, as well as cleaning encrusted residue.

What is an unclogging machine for?

The main function of an unblocking machine is to restore the flow of water in blocked pipes. It is used in a variety of situations and locations, playing a crucial role in:

  • Residences;
  • Commercial establishments;
  • Industries;
  • Sewage and rainwater systems;
  • Preventive maintenance.

How much does it cost to hire an unblocking machine?

The cost of hiring an unblocking machine can vary widely depending on several factors.

For simple residential blockages, such as a sink or toilet, the cost can vary from R$150 to R$400, on average.

However, more complex blockages, such as problems in sewage systems or larger pipes, may require more specialized services, and costs can reach R$1,000 or more.

It is important to obtain quotes from different companies and professionals to determine the exact cost, as the location, severity of the clog and time of day can influence the final price.
