Comet New Scout 150 Extra - 150 bar Hot Water Pressure Washer with Integrated Hose Reel
The Comet Scout 150 Extra is a semi-professional hot water pressure washer designed for professionals working in demanding environments such as workshops , light construction sites or agricultural businesses , where stubborn dirt, grease and encrustations require quick and effective interventions. This model guarantees high and consistent performance, ensuring deep cleaning thanks to the delivery of hot water up to 90°C . At the heart of the machine is the Comet KSR Gold self-priming pump , with three stainless steel pistons and a brass head, a superior quality component that offers reliability and durability well beyond typical standards in the category.
This pressure washer is designed to optimize daily work, integrating intelligent management and safety systems. Functions such as Total Stop and EASY START reduce energy consumption, limit component wear and allow for quick and immediate start-up of the machine. With 150 bar of pressure and a flow rate of 540 L/h , this pressure washer combines power and practicality: the robust structure is easily moveable thanks to the large 260 mm rear wheels , while the front and rear bumpers protect the machine during transport, making it ideal for intensive use in professional contexts.

Technical Specifications
The Comet Scout 150 Extra has a single-phase 230V power supply with a total power of 2.7 kW , a perfect balance for offering high performance without the need for complex industrial electrical systems. The 2-pole motor , operating at 2800 RPM , drives the Comet KSR Gold pump, designed to last over time: the three stainless steel pistons and the brass head guarantee superior resistance to wear and the most aggressive chemical agents. The condition of the oil in the pump can always be checked thanks to the practical viewer, while hydraulic performance remains constant, with a maximum pressure of 150 bar and a flow rate of 540 L/h , ideal values for quick and effective professional cleaning jobs.


On the thermal front, the Scout 150 Extra pressure washer uses a diesel burner located in a 15 L tank equipped with a removable filter for easy maintenance. This system allows water temperatures of up to 90°C to be reached, while maintaining a low consumption of 3.11 kg/h and optimizing energy efficiency. Detergent management is convenient thanks to the integrated 3.5 L tank , which is easily accessible and can also be used by suction from external containers. The machine guarantees operational safety thanks to the amperometric motor protection , the thermostat for temperature control and the safety valve. Finally, the professional glycerine-filled pressure gauge offers a precise and cushioned pressure reading, allowing constant monitoring during all operations.


Functional Specifications
Amperometric protection against overloads
The motor's current protection function is an essential safeguard for the integrity of a professional pressure washer. This advanced monitoring system intervenes promptly to deactivate the power supply in the event of excessive current draw caused by overloads or electrical anomalies. This feature not only prevents costly damage to the motor and electrical components, but also ensures the equipment maintains its long-term operational reliability, a critical aspect for professionals.
Total Stop and Easy Start System
The winning combination of the Total Stop device and the EASY START device redefines efficiency. The Total Stop device instantly shuts down the machine when the gun is released, eliminating energy waste and wear on the pump unit during downtime. The EASY START device facilitates a smooth and immediate restart of the engine, even in the presence of voltage fluctuations, reducing start-up stress and making the pressure washer immediately operational. These combined systems extend the life of components and optimize consumption during intermittent work cycles.


Temperature regulation thermostat
The temperature control thermostat gives the operator control over the heat of the water dispensed, allowing them to precisely select the most effective temperature level up to 90°C , depending on the dirt being treated and the surface. This is crucial for dissolving grease and oil, as well as for sanitizing and degreasing, optimizing the detergent's effectiveness. Accurate temperature control ensures optimal results and protects sensitive materials.
Low pressure detergent suction
The low-pressure direct water intake feature with detergent allows for quick and targeted application of chemicals. When the operator reduces operating pressure, the pressure washer automatically draws cleaning solution from the integrated tank or an external source. This is ideal for pre-treating surfaces or for final low-pressure rinsing, ensuring uniform coverage and optimizing professional cleaning times.


Delayed burner start
The delayed burner start is a technical mechanism that ensures the heating system activates only when the pump and water flow have reached a stable state. This protected sequence is essential for preventing the burner from dry-firing, increasing its reliability and reducing the risk of failure. The result is a stable and safe flow of hot water from the start, improving operating efficiency.
Integrated hose reel and structural protections
The Comet New Scout 150 Extra is also designed for operational logistics. It features an integrated hose reel with 10 m of R1 high-pressure hose , improving hose organization and durability. Movement is facilitated by the large rear wheels and the swivel front wheel with brake . The structure is reinforced with front and rear bumpers to withstand the impacts typical of work environments. Details such as the easily removable handle and the lance holder with rubber supports complete the design, aimed at maximum practicality for the professional user.
