Cleaning challenges
What do you want to tackle first with pressure washing?
Contractors work across property estates, courtyards, steps and vehicles, requiring everyday washing equipment that can move between jobs.
Ordinary water guns can take time on moss, dust, mud and wall/step stains.
When the material, nozzle, and distance are not confirmed, you cannot rely solely on the pressure number.
Site conditions, configuration and selection
Where is the cleaning taking place, and what are the conditions? Determine the configuration together.
The following is a selection reference, which does not replace original technical data, on-site verification, and trial washing.
01 Courtyards and Staircases
Focus on verifying materials and slip resistance.
02 Property surroundings
Focus on verifying water source and drainage.
03 Vehicle Exterior
Check the paint surface and no-water areas.
04 External Store
Prioritize checking for pedestrians and barriers.

— FAQ
You may also be interested in J-1612D
Make judgment based on the tasks, configuration, and usage conditions of this model.
Only when there is 220 V power, what should be confirmed first?
Provide socket and wiring conditions, and have qualified personnel check the power supply and protection according to the random instructions for this model; it is not acceptable to equate "able to connect to electricity" with being usable on any wiring.
Can the configuration of J-2515D be directly copied?
Cannot. The power supply and flow rate records of the two models are different; the pump, pipe gun, and delivery list must be checked individually.
How to distinguish between courtyard and vehicle washing?
Before inspecting the yard, check for slip resistance and drainage. For vehicles, inspect the paint, sealing, and water-proof areas on the exterior. Test each area separately, and do not use the same distance and angle for all materials.
Which working pressure applies to the machine I will receive?
The historical pressure rating of J-1612D still needs to be determined based on the original documentation, and similar model parameters are not considered as the standard for this machine.
What documents should be provided during selection?
Cleaning object, surface material, dirt, no-water areas, working distance, water supply and drainage conditions. For electric solutions, check the on-site power supply.
How to confirm standard and optional configurations?
Verify each item on the order and delivery list. The long brush, angle nozzle, and base hose are separate from the additional hose length, rotating head, and floor scrubber, and are not determined by the image.
Where should daily maintenance start?
Retain the J-1612D name plate, configuration sheet, and random instructions. Check power supply and protection, inlet water, piping, and spray gun. Oils, cycles, and disassembly are according to the machine's instructions. The website does not provide its own cycle.
What should be done if there is abnormal water discharge or pressure?
Follow the random instructions of J-1612D for shutdown processing, record the water source, fittings, pipelines, and abnormal phenomena, then contact after-sales.
