Formerly the Poseidon 4-29, the new Gerni MC 4-M features increased power, a new design and a unique and fast foam sprayer system with a separate bottle for efficient cleaning.

Achieve faster, more effective and intelligent cleaning with the new Gerni MC 4-M. A portable single phase cold water pressure cleaner, designed for light to moderate commercial use.

The Gerni MC 4-M boasts increased power, a new design and a unique foam sprayer increasing nozzle pressure by up to 20%. This adds up to superior cleaning results, saved time and lower costs.

Motor-pump power and easy and reduced maintenance costs

The powerful performance of the MC 4-M is ensured by a high-quality 1450 rpm motor-pump with a brass pump head. It also has a pressure activated un-loader system and an updated design.

To reduce running costs, the serviceability has been increased. The MC 4-M gives easy access to the motor and pump.

The on-board pump oil tank with fill/empty system makes maintenance tasks like oil checks very easy for the user.

Foam makes the difference, like touch-less car washing

Detergent is supplied more effectively through a new separate foam sprayer system.

This is how touch-less car washes work. Clean a large truck in less than half the time, without using brushes, which may pick up grit and scratch the paintwork of the tractor units of rigs, owned by professional drivers.

Cleaning dust, dirt, and mud, can, in most cases be carried out with cold water, however, when it comes to more challenging grease and fats, detergent must be added.

Until now detergents have been supplied by a built-in injector but now Gerni has developed a unique foam sprayer system with a separate bottle and foam sprayer, reducing energy loss and guaranteeing an increase in nozzle pressure and cleaning power.

Robust and safe to handle – more intuitive and easy use

The MC 4M is more robust, with larger 250 mm wheels to give good ground clearance over rough surfaces and a new spray gun holder. The new holder protects the spray gun from falling on the ground and being dragged behind the machine - essential to safe storage and transportation.

The Gerni MC 4-M is the ideal choice for small builders, handy-people, tradies, farms, stables and dairies, boat yards, car yards and car rental companies.
