The Cyclops drain plunger No2 is a tool used for cleaning and unclogging pipes such as external sewage pipes or boiler rooms.

This plunger creates negative pressure to remove waste and debris from the pipes, allowing the restoration of normal water or sewage flow.

No2 usually refers to the size or type of the plunger, and may refer to different models or features.

It is recommended to choose the appropriate plunger model based on your needs and the type of work you want to perform.
