Selected-model comparison
Select up to three models to compare tasks and configurations.
No equipment selected.
Selection requires pressure, flow, power, contamination and continuous-duty needs to be considered together. Light property washing, factory equipment, outdoor projects and heavy equipment need different configurations.
Three checks for pressure-washer selection
Describe the washing difficulty before pressure-washer selection.
Describe the object, dirt and utilities first; you need not start with MPa or L/min.
Select the power source first, then pressure and flow
Check whether the site supports 220 V, 380 V or requires petrol power. Then select pressure and flow for the cleaning object and soil.
First select power, then compare pressure and flow, and finally confirm water supply, hose lengths and nozzles.
1. Select the power source available on site
220 V supplyWhere a suitable 220 V supply is available, consider 220 V electric models first. Reference model: J-1612D.View reference models and specifications →PetrolFor outdoor sites without fixed power or requiring frequent relocation, consider petrol models first. Reference model: J-2815C.View reference models and specifications →380 V supplyWhere a suitable 380 V industrial supply is available, consider 380 V electric models first. Reference model: J-2050D.View reference models and specifications →
2. Select pressure and flow for the cleaning task
After selecting the power source, match pressure to soil adhesion and surface material, and compare flow against the required flushing volume. Higher pressure is not always better, and total machine flow is not the flow available to each gun.
3. Confirm that the configuration suits the site
Check supply capacity and connections for electric models. Petrol equipment is for suitably ventilated outdoor locations, not enclosed indoor areas. Confirm continuous water supply, wastewater disposal and material compatibility for all equipment.
Check the model nameplate, configuration and operating instructions
Check the model nameplate, configuration and accessories. Trial critical cleaning conditions and access on site before purchase.
Start with the available 220 V, petrol or 380 V power source, then provide the cleaning object, soil photographs, water supply and continuous working time. Drawing on over 20 years of industry experience, we help shortlist equipment and identify configurations requiring confirmation.
Submit conditions to compare configurationsRelated applications and selection guidance
Determine selection direction from the site problem
Is higher pressure always better for walls?
Assess surface tolerance, adhesion and surrounding protection before nozzles and distance. Trial fragile surfaces; pressure alone cannot guarantee removal.
Why is pressure alone insufficient for surface washing and pipe jetting?
Surface cleaning depends on material and jet coverage. Pipe work also depends on blockage, access, bends and contaminated-water drainage. Accessories and site arrangements differ between the two tasks.
Quick selection
Compare pressure, flow and power according to the site.

Pressure / Flow / Power matrix
Look beyond pressure: define three aspects of the task first.
Pressure, flow and power jointly affect cleaning, continuous duty and site compatibility.
For light-to-medium property washing, assess 220 V access, stable water supply and surface safety.
Common medium/higher-pressure industrial, vehicle and outdoor tasks.
For more demanding industrial or outdoor work, compare 380 V/petrol options and 15/22 L/min flow configurations.
For heavy equipment and stubborn deposits, confirm material, nozzle distance, protection and water supply first.
Routine industrial and balanced washing where objects are defined and grit loads are moderate.
Emphasizes coverage and transport of grit or loose dirt.
Confirm power and ventilation before light/medium, fixed-industrial or outdoor-mobile selection.
Pressure washers by application
Identify object and contamination before pressure, flow and power.

When is a 500bar（50MPa） pressure washer genuinely needed?
Consider the 500bar（50MPa） class only for heavy equipment, stubborn deposits or specialist industrial maintenance, after checking material and protection.
Related models: J-5022D / J-5015H / J-5022HView equipment selection for this application →Choosing pressure and flow
Assess jet impact, coverage and site conditions together.
| Assessment factor | Main influence | Selection reminder |
|---|---|---|
| Pressure | Jet impact and adherent-deposit removal capability. | Higher pressure requires closer material, distance, protection and damage-risk assessment. |
| Flow | Washing coverage and removal of grit or loose contamination. | Grit, large washing areas and difficult drainage need more than pressure assessment. |
| Nozzles | Fan, rotary, pipe-jetting or specialist nozzles. | At the same pressure/flow, nozzles substantially affect impact, coverage and safety boundaries. |
| Water supply | Supply stability, inlet volume and filtration. | Insufficient water can affect pressure, pump durability and continuous operation. |
| Contamination type | Grit, mud, moss, rust, old paint or mixed deposits. | Different contamination needs different pressure, flow, nozzles and distances; one model cannot cover every task. |
| Surface material | Concrete, stone, metal, coatings and vehicle paint. | Test fragile or coated surfaces first to avoid damage from high pressure. |

How should pressure and flow be compared?
Describe the object, dirt, distance and utilities before pressure/flow; pressure alone cannot predict results.
Stubborn deposits: assess surface tolerance, nozzle, distance and site trials together.
Carrying dirt away: assess flow, water supply and wastewater arrangements.
For long operating periods, verify rated duty, power supply and maintenance requirements.

Provide the cleaning object, contamination, area, working distance, power and water supply, frequency and wastewater arrangements.
— FAQ
Questions before buying a pressure washer
Is higher pressure always better?
No. Higher pressure increases impact and potential damage to coatings, stone, paint or fragile surfaces. Assess contamination, nozzles, distance and material together.
Is higher flow always better?
More flow can improve loose-deposit transport and coverage, but requires adequate supply, drainage and control. Routine equipment cleaning may not need maximum flow.
How should I choose a 220 V or 380 V pressure washer?
Assess 220 V for property sites, smaller premises and routine washing; assess 380 V for sustained work at fixed factories, workshops and vehicle-maintenance sites.
Which tasks should assess petrol pressure washers?
Petrol equipment can be assessed outdoors on construction/farm sites without fixed power; never operate it indoors or where exhaust can accumulate.
What pressure should be assessed for moss?
Assess moss adhesion and material first. Consider light-to-medium or moderate pressure, adjusting nozzle and distance rather than immediately using excessive pressure.
Can high pressure damage a floor?
Possibly. Trial floors, stone, coatings, paint and aged concrete before setting pressure, nozzles and distance.
What happens if the water supply is inadequate?
Insufficient water can destabilize pressure, increase pump load and interrupt cleaning. Confirm supply especially for high-flow models.
When should I consider 500bar（50MPa）?
Assess 500bar（50MPa） for eligible heavy equipment, deposits or specialist maintenance requiring greater impact, with material tolerance and safety checked together.

Pressure-washer industry news and selection resources
Pressure-cleaning industry trends, selection and purchasing news
Pressure-cleaning selection approach
Pressure provides impact; flow carries dirt away.
Pressure alone does not determine cleaning suitability. Equipment grease, vehicle mud, factory floors and construction sites require combined assessment of pressure, flow, power, water and nozzles.
Identify the object and deposits first.
Oil, grit, rust, graffiti and loose dust need different methods. Define the object before cold/hot water or higher-intensity washing.
Electrical supply and power type determine deployment options.
Consider 220 V for routine mobile tasks, 380 V for fixed industrial sites, and petrol for outdoor projects requiring mobility without fixed power.
Pressure and flow affect the work sequence.
Pressure acts on deposits; flow provides coverage and transport. Contractors and large factories should assess sustained capacity against shift workload.
