Typical application
Outdoor hard-surface pressure washing: lance, optional bars and water handling
Identify the object before power, material tolerance, delivered configuration and waste destination. More pressure is not automatically more suitable; a pictured accessory is not necessarily included.
Assess a lance for local targeting and a bar only as a verified compatible assembly. Organise work by water handling and trials, not fixed-output or measured-saving promises.
- Exclude petrol units from underground, indoor and exhaust-trapping semi-enclosed locations.
- Verify actual electrical supply, water protection and permission; 380 V is not explosion protection.
- Do not operate until surface, nozzle and accessory compatibility are verified.
- Provide suitable waste recovery/disposal; original images do not prove customer delivery.
Outdoor hard floors: distinguish loose mud from bonded soil
J-3515H
Connect local soil removal, sediment collection and sectional reopening to reduce unnecessary wetting and repeat cleanup. Suitable nozzles, distance and a trial help protect compatible surfaces.
01 · What makes this task difficult?
Water-compatible factory/property hard floors can carry loose mud, wheel marks and bonded local soil. Re-deposition, access conflicts and insufficient supply/disposal are common problems. An image proves no pressure tolerance of stone, coatings or joints.
Loose sediment and bonded soil mix
Collect loose debris before trial-cleaning deposits
Cleaning affects traffic and nearby objects
Protect sensitive objects and plan supply, drainage and handover
02 · Why consider this Jinjie machine?
Match the current model’s power, pressure, flow and nozzle to local deposits on water-compatible hard surfaces, then manage sediment toward a collection route. Verify each machine’s supply rather than interchanging gasoline and electric configurations.

Outdoor hard floors: distinguish loose mud from bonded soil
Site, material and contamination
Water-compatible factory/property hard floors can carry loose mud, wheel marks and bonded local soil. Re-deposition, access conflicts and insufficient supply/disposal are common problems. An image proves no pressure tolerance of stone, coatings or joints.
Equipment basis and model differences
A single lance allows staged targeting of local soil. Water capacity and material tolerance drive the plan; higher pressure is not automatically better. Unresolved pressure terminology or delivered configurations of J-5015S, J-3515H and J-5022H are not recommended operating settings. Verify 380 V supply, electrical protection and cable management for J-1730D. Petrol units operate only in suitable open outdoor space away from doors/windows and air intakes. Do not borrow H/HS component materials.
Model configuration and selection
Check model-specific configurations against the machine and order before purchase.
| Model | Current basis and limits |
|---|---|
| J-3515H | Current information lists 15 L/min, a GX630 twin-cylinder petrol engine and AR pump. Verify the maximum/working basis of the 350bar（35MPa） entry; assess only open outdoor non-hazardous tasks. |
| J-3522H | Current information lists 22 L/min, Honda twin-cylinder petrol power and AR pump. Pressure terminology remains unresolved; no parallel-operator or time-saving promise is made. |
| J-5015S | The current page lists maximum 500bar（50MPa）, 15 L/min and petrol positioning. Engine brand and delivered pressure configuration are order-specific. The single lance is standard; a surface cleaner and other attachments are optional. |
| J-5022H | The current page lists 22 L/min, petrol power and AR pump. A maximum-500bar（50MPa） headline coexists with unresolved terminology; it is not certified working pressure. |
| J-1730D | Current information lists 170bar（17MPa）, 30 L/min and 380 V electric power. A long single lance is standard; flushing bars and rotary heads are optional, not evidence of simultaneous multi-gun capability. |
| J-1730HS | Model information lists maximum 170bar（17MPa）, 30 L/min, GX390 petrol engine, AR pump and a 304 stainless-steel reel. Frame material is separate; a flushing bar is optional. |
| Site problem | Equipment / conditions | Suggested method | Potential value |
|---|---|---|---|

Working method, accessories and site supply
- Prepare and trial · Collect larger debris first and identify finish, joints and soil. Trained staff trial under the machine and surface instructions.
- Supply, collection and separation · Verify sustained supply and waste collection; isolate sections without flushing sediment towards people or unauthorised drains.
- Single-lance work · Use compatible nozzle, distance and method under the instructions. Avoid electrics, loose finishes and sensitive parts; no unverified pressure setting is prescribed.
- Stop and hand over · Stop/depressurise before changing tools. Collect waste and inspect surface, slip risk and access before handover.
Limits and safety
Exclude petrol units from underground, indoor and exhaust-trapping semi-enclosed locations. Verify actual electrical supply, water protection and permission; 380 V is not explosion protection. Do not operate until surface, nozzle and accessory compatibility are verified. Provide suitable waste recovery/disposal; original images do not prove customer delivery.
Questions for this task

FAQ
Can a 500bar（50MPa） maximum rating be applied directly to property floors?
No. A maximum is not a recommended setting; verify working specification, surface tolerance and a trial.
Does more water remove the need for waste collection?
No. Supply, contaminant recovery and drainage capacity must be assessed together.
What site information is needed for selection?
Provide surface/joint and soil photos, area, access times, supply/recovery route, actual power and configuration list.

J-2815H
With compatible accessories and sufficient supply and disposal, coordinate flushing routes with collection to reduce blind tool changes and unnecessary passes. Assess equipment and labour costs against the actual scope.
01 · What makes this task difficult?
These original images show multi-outlet bars for compatible hard floors and loose residues. Assess coverage, transport and water handling rather than confusing multiple outlets with simultaneous operators.
Loose sediment needs organised collection
Trial toward collection before defining routes and coverage
Accessory and machine ratings may differ
Verify the configuration and supply instead of guessing from nozzle count
02 · Why consider this Jinjie machine?
A multi-nozzle flushing bar is an optional method for suitable hard-surface sediment only after rated pressure, flow, connections and machine compatibility are confirmed. It is not standard on every model and nozzle count does not establish output.

Equipment basis and model differences
Bars for J-2815H, J-1730D, J-1730HS and J-2050H are model/order-specific options, not standard equipment because they appear in an illustration. Obtain compatibility data for nozzle count/bore, total flow, rated pressure, connections and hose. Without it, select no attachment and promise no parallel work or time saving. The pictured bar establishes the illustrated method, not the delivered accessory model, working pressure or area output. J-1730HS's 304 statement covers its reel, not the bar or frame.

01 · What makes this task difficult?
Two original J-1020D images show lance work on floors and channel edges. The task is compatible service-area hard flooring, loose mud and residues, with collection to avoid merely pushing waste into a blocked opening. Visible water does not prove pipe clearance.

Equipment basis and model differences
The current 100bar（10MPa）, 20 L/min electric positioning supports local-task assessment; verify nameplate supply rather than borrowing another model's voltage. Specialist surface tools are project-specific options. The images show a lance, not hose-fed jetting or large-area scrubbing. Even open service entrances require checks of electrics, supply, drainage and people. Indoor or sensitive sites need separate assessment.
