Pressure Washers Comet

Comet pressure washers produce a high-pressure water jet suitable for removing mud, dust, scale, grease and debris from outdoor floors, vehicles, agricultural equipment and machinery. Comet was founded in Reggio Emilia in 1959, initially manufacturing pumps for crop treatment. Over the following decades, it expanded its expertise across the Agriculture, Industry and Cleaning sectors, adding a range of domestic, semi-professional and professional cleaning machines to its pumps.

The range combines the brand’s expertise in pressurised water technology with configurations designed for different working environments. Electric cold water models cover routine cleaning around the home, yards and vehicles; hot water machines act on oily residues; petrol versions operate away from the mains; tractor-mounted units support intensive agricultural work. The choice depends on the type of dirt, frequency of work, availability of electricity and flow rate and pressure values.

This selection also includes the following types of Comet pressure washers, designed for different operating conditions:

• Comet Cold Water Pressure Washers: they use the incoming water without heating it and cover domestic, semi-professional and professional work. They are suitable for floors, walls, vehicles, outdoor furniture and equipment;
• Comet Hot Water Pressure Washers: they incorporate a boiler that combines the mechanical action of the jet with the degreasing action of heat. They are suitable for the frequent removal of oil, grease and stubborn dirt in workshops, farms and construction sites;
• Comet Petrol Pressure Washers: they use a petrol engine and do not require a connection to the mains. They provide mobility on construction sites, farmland and outdoor spaces far from a power socket;
• Comet Heavy-duty Tractor-mounted Pressure Washers: they use the tractor’s power take-off to drive the high-pressure pump. They are configured for intensive cleaning of vehicles, equipment, livestock buildings and agricultural facilities across large surfaces;

At AgriEuro, Comet pressure washers can be selected according to their technical features, helping identify a machine suited to the frequency of work, surface and type of dirt. Several parameters should be compared together, since the maximum pressure alone does not describe the machine’s overall operating capacity.

• Flow rate: expressed in litres per minute or hour, it indicates the quantity of water delivered and affects how quickly dirt is removed from the surface;
• Pressure: measured in bar, it describes the force of the jet. It should be assessed together with the flow rate and adjusted carefully on delicate surfaces, seals and paintwork;
• Power supply: electric configurations may be single-phase or three-phase; petrol models work without an electrical socket; tractor-mounted units receive power from the PTO;
• Water temperature: cold water models use mains water; hot water models incorporate a boiler and add thermal action against grease and oily residues;
• Pump and pump head: materials and construction vary by model. Brass pump heads and pumps with ceramic pistons are fitted to specific machines intended for more demanding work;
• Engine: power, rotational speed and fuel or power source affect operating continuity. On professional models, the engine is sized for longer and more frequent workloads;
• Stop systems: where fitted, Total Stop interrupts operation when the spray gun trigger is released, limiting idle running of the motor-pump unit;
• Equipment: hose reels, detergent tanks, foam lances, brushes, nozzles and vehicle-cleaning accessories extend the applications of each model;

Hobby machines cover occasional cleaning of cars, garden furniture and driveways. Semi-professional versions support more frequent jobs; professional machines are intended for workshops, companies, farms and construction sites, where flow rate, strength and operating continuity carry greater weight.

The Comet range includes machines with different structures, power sources and water temperatures. Each configuration offers a specific balance between mobility, cleaning intensity and operating continuity. Comparing the different types helps match performance to actual working conditions.

Comet Cold Water Pressure Washers are the most common choice for cleaning flooring, façades, fences, garden furniture, cars and equipment. Mains water is pressurised by the pump without passing through a boiler, resulting in a more compact structure than hot water versions. Single-phase models can be connected to standard domestic supplies; three-phase configurations are intended for professional environments with a suitable electrical system. Pressure and flow rate should be assessed together, as a good volume of water helps loosen and carry away residues. Depending on the model, equipment may include a brass pump head, three-piston pump, hose reel, detergent tank and Total Stop system. This type therefore covers both occasional and frequent work, with dimensions and equipment to be selected according to the surface and expected duration of each cleaning session.

The main configurations differ in the following respects:

• Single-phase power supply: suitable for domestic sockets and periodic cleaning around the home;
• Three-phase power supply: intended for professional electrical systems and more demanding sessions;
• Cleaning accessories: lances, nozzles, brushes and foam systems allow the jet to be adapted to different surfaces;

Comet Hot Water Pressure Washers combine pressure, flow rate and temperature to treat grease, oil and stubborn residues. A boiler heats the water before delivery, adding thermal action that is useful in workshops, farms, dealerships, construction and production environments. Heat helps dissolve oily residues and may reduce the need for higher pressure, always in accordance with the model instructions and the surface being cleaned. The boiler increases the machine’s size, weight and maintenance requirements compared with a cold water model, which should be considered together with the frequency of work. The AgriEuro selection includes configurations with different pressure and flow rate values, ranging from semi-professional to professional machines. The electrical supply, fuel tank capacity, temperature adjustment, hose length and included accessories should also be checked. A suitable choice supports more consistent cleaning cycles on heavily soiled machinery and surfaces.

Features to assess for this type include:

• Integrated boiler: heats the water to the temperature specified for the machine to act on greasy residues;
• Temperature adjustment: on suitable models, this allows the temperature to be adapted to the material and dirt;
• Professional applications: the structure and components are designed for frequent cleaning in production and service environments;

Comet Petrol Pressure Washers are suitable for locations where mains electricity is unavailable or far from the cleaning point. The petrol engine drives the pump, allowing work on construction sites, farmland, yards and outdoor spaces with greater freedom of movement. The range includes different engine capacities and performance levels, which should be matched to the available water flow and duration of the work. Compared with an electric machine, weight, noise, fuel consumption and engine maintenance require specific consideration. High pressure values should be paired with an adequate flow rate and nozzles suited to the task, avoiding excessively concentrated jets on paintwork or fragile materials. The frame, wheels, high-pressure hose and control layout affect practicality when the machine is moved frequently. These machines are intended for semi-professional and professional applications where mobility and power take priority over connection to an electrical socket.

Before choosing, it is useful to compare the following aspects:

• Petrol engine: removes the constraint of mains electricity and requires the periodic checks specified by the manufacturer;
• Engine capacity and power: together with the pump, these determine the machine’s performance level;
• Mobile structure: the frame and wheels make it easier to move between different cleaning points;

Comet Heavy-duty Tractor-mounted Pressure Washers use the power take-off to drive the pump and are intended for agricultural work requiring intensive cleaning away from mains electricity. Their configuration allows tractors, equipment, trailers, operating machinery, livestock buildings and farm facilities to be cleaned with flow rates suitable for removing large amounts of mud and debris. Before purchase, compatibility with the tractor, PTO speed and connections specified for the individual model must be checked. The water supply must also provide a volume consistent with the pump flow rate, without restrictions or insufficient suction. Operating pressure, hose length and lance type affect working distance and jet control. These units are designed for continuous professional work and require regular checks of oil, couplings, hoses and wear components. The choice should therefore be based on the complete tractor-pump-water supply system.

The main comparison criteria include:

• PTO compatibility: speed and connection must comply with the specifications of the machine and tractor;
• High flow rate: supports the cleaning of large machinery and the removal of mud and debris;
• Professional equipment: hose, lance, frame and couplings should be selected according to working frequency and distance;

For periodic domestic cleaning, a single-phase electric Comet cold water pressure washer is generally suitable. The model should be selected according to the surface, frequency, type of dirt, flow rate and pressure. Weight, dimensions, hose length and dedicated accessories also matter when cleaning cars, furniture, small yards and driveways. An adjustable jet helps work on different materials without applying excessive force.

Flow rate and pressure should be assessed together, but flow rate directly affects the volume of water that carries dirt away. Pressure expresses the force of the jet; high pressure with little water may be less productive on large surfaces. When comparing two models, the operating values, expected frequency and task should therefore be considered instead of relying solely on the maximum bar rating.

A hot water pressure washer is worthwhile when recurring work involves grease, oil and stubborn residues. Heat works together with pressure and flow rate, helping loosen dirt in workshops, farms and production environments. The machine’s greater complexity should also be considered: the boiler, fuel tank, dimensions and maintenance require space and specific checks. A cold water version may be sufficient for ordinary outdoor dirt.

The main advantage is the ability to work without a mains electricity connection. A petrol machine is suitable for construction sites, farmland and yards far from power sockets, provided an adequate water supply is available. Fuel, noise, weight and engine maintenance should be considered. Engine capacity, flow rate and pressure must be proportionate to the intensity of the work rather than selected as isolated figures.

The machine receives power from the tractor’s PTO, which drives the high-pressure pump. This solution is suitable for cleaning machinery, equipment and agricultural facilities where electricity is unavailable. Before connection, the PTO speed, attachment compatibility, available water volume and manufacturer’s instructions must be checked. An insufficient water supply can cause irregular operation and damage the pump.

Where fitted, Total Stop stops the motor-pump unit when the spray gun trigger is released and restarts it when work resumes. The system limits idle operation during pauses and reduces component running time. Operation and procedures may vary between models, so the technical data and manual for the specific Comet pressure washer should be checked.

No, a brass pump head is fitted only to specific models. Pump-head material and pump configuration vary according to the range, performance and professional classification. Some machines also use in-line pumps with three ceramic pistons for demanding work. The product specifications should be checked before purchase, without extending a feature stated for one series to the entire range.

Routine maintenance includes checking the inlet filter, nozzles, couplings and high-pressure hose. After work, the residual pressure should be released and the procedures in the manual followed. Petrol machines also require engine checks; hot water models add boiler inspections. Before winter storage, the circuit should be protected from frost and water should not be left inside the components.

The most common causes are insufficient water flow, a dirty filter, a blocked nozzle or air in the circuit. The tap, supply hose, couplings and nozzle cleanliness should be checked in accordance with the manual. A kinked or narrow hose can restrict the water supply. If vibration and pressure loss continue after routine checks, operation should stop and assistance should be requested.

Yes, on compatible models, detergent can be delivered through a tank, suction hose or foam lance. Products compatible with the pressure washer must be used, following the dosages and procedures in the manual and the pressure setting required by the system. Afterwards, the affected circuit should be rinsed with clean water. If suction is weak, the filter, hose and pressure setting should be checked before requesting assistance.
