Cleaning challenges
What do you want to tackle first with pressure washing?
Everyday machines may be insufficient for contractors' factory-floor, equipment and vehicle tasks.
Workshops, workstations, concentrated property washing and vehicle maintenance need a stable electric configuration.
Pressure washing requires more than a machine: assess 380 V, supply and drainage.
Site conditions, configuration and selection
Clarify the cleaning task, then match the equipment configuration.
The selection should be determined by the cleaning object, contaminants, water source, power supply, and working attachment, rather than solely based on the maximum pressure.
01 Exterior of equipment
First check the material, sensitive areas, and dirt.
02 Factory Area Floor
First, check the floor, dirt, and drainage routes.
03 Fixed work position
First check the continuous water supply, power supply, and usage period.
04 Vehicle Exterior
First check the vehicle requirements, nozzle, and operating distance.
| Task | Objects and dirt | Water source and wastewater disposal | Judgment of working pressure and flow | Power, spray gun and accessories |
|---|---|---|---|---|
| The equipment should be rinsed at specific points on the exterior. | The outer shell, frame, and other water-washable surfaces; first distinguish between floating dust, adhered dirt, and oil stains. | The water source should be continuous, and wastewater can be collected; electrical and sensitive areas should be protected first. | Combine material test washing, working pressure, and nozzle compatibility, without using maximum pressure to replace continuous operating conditions. | Check industrial power according to the nameplate; long nozzle spray gun should be matched with appropriate nozzles, and direct impact on electrical parts should be avoided. |
| Factory hard-surfaced areas | First, confirm the floor material, joints, and coating; distinguish between mud and adhered dirt. | Check the water supply, drainage slope, and silt collection to avoid merely flushing the dirt to another place. | Balancing the requirements of sludge removal and flushing, the flow rate and discharge conditions should be evaluated together. | Check power supply and hose routing; the floor scrubber and flush attachment are optional, test the cleaning first to confirm effectiveness. |
| Fixed cleaning station | The task is relatively focused. First, list the daily cleaning objects, dirt, and usage time. | Confirm continuous water supply, inlet conditions, and wastewater discharge, to prevent water shortage from affecting operations. | Current standard pressure and flow are for configuration reference only; continuous operation conditions should be verified against the machine's original settings | First verify the power supply and protection; confirm the gun tube connection based on the working distance, and include the accessories and hose length in the delivery list. |
| Factory vehicle exteriors | First, distinguish between the paint surface, chassis, and sensitive components; then determine whether high-pressure washing is allowed based on the vehicle requirements. | Schedule vehicle parking, water supply, and wastewater collection without affecting traffic | From the perspective of material, nozzle, and working distance, it is not advisable to choose based on the higher pressure. | Check power supply, hose routing, and personnel isolation; use matching nozzles, avoiding impact on seals and electrical components. |
Before selection, it is recommended to bring these four pieces of information.
- Cleaning objects, surface materials, contaminants, and sensitive areas.
- Continuous water source, inlet conditions, and wastewater discharge direction.
- Available power, task time, and hose route.
- Required nozzles, spray tips, optional accessories, and operating distances.
The above is a reference for selection, and the final decision is based on the machine's data, on-site conditions, and trial washing confirmation.
