Water System Options
The Leisuwash SG supports three water management configurations:
3. Washing Process & Technology {#washing-process}
The Leisuwash SG employs a 6-stage precision washing protocol engineered to deliver a spotless, streak-free finish without any physical contact with the vehicle’s paint surface.
Stage 1: Vehicle Detection & Profile Scanning
Before a single drop of water is released, the SG’s laser profile scanner maps the vehicle’s three-dimensional shape — roof contour, door mirrors, antenna position, and wheel arch geometry — with ±3mm accuracy. This data is fed to the Siemens PLC, which dynamically adjusts spray arm angles and pressure zones throughout the wash cycle.
Why it matters: Precise profiling eliminates the risk of high-pressure jets contacting delicate surfaces (door seals, windshield wipers, antenna mounts) at damaging angles — the leading cause of damage claims in inferior touchless systems.
Stage 2: Chemical Pre-Soak Application
Dual-nozzle pre-soak arches apply a pH-balanced alkaline foam to the entire vehicle surface. The foam dwell time (30–90 seconds, configurable) allows the active chemistry to:
Stage 3: High-Pressure Wash
The SG’s rotary oscillating spray arms — a Leisuwash proprietary design — deliver 800–1,200 bar water pressure in a sweeping pattern across all vehicle surfaces simultaneously. Unlike fixed-nozzle competitors, the oscillating geometry ensures complete coverage of complex surface profiles (door handles, wheel arches, rocker panels) with no wash shadow zones.
Key technology differentiator: The variable-pressure algorithm automatically reduces nozzle pressure when the scanner detects flexible aerials, chrome trim, or sensor housings — preventing damage that fixed-pressure systems cannot avoid.
Stage 4: Rinse & Chemical Neutralization
A triple-stage progressive rinse removes all pre-soak chemistry and loosened contamination. The final rinse stage uses either:
Stage 5: Spot-Free Final Rinse
The SG’s integrated spot-free rinse arch applies a final ultra-pure water coat that sheets off the vehicle surface in a continuous film — eliminating individual water droplets that leave mineral spots during air drying.
Stage 6: High-Velocity Air Drying
Dual 7.5kW overhead blowers combined with optional side-mounted air curtains reduce surface moisture by 85–95%, delivering a near-dry finish suitable for immediate customer collection. Drying quality significantly exceeds that of a single overhead blower — a key differentiator versus lower-cost alternatives.
4. Key Features & Competitive Advantages {#features}
Siemens PLC Control System
The heart of the SG is a Siemens SIMATIC S7-1200 PLC, the industry’s gold standard for reliability in industrial automation. Key advantages over proprietary PLC systems used by some competitors:
Leisuwash Cloud IoT Platform
Every SG unit ships with integrated 4G/Wi-Fi remote monitoring connectivity. Operators access real-time and historical data via the Leisuwash Cloud Platform dashboard:

| Real-time wash counter | Live transaction count and daily/weekly/monthly totals |
| Chemical consumption tracking | Per-wash usage data; alerts for low chemical levels |
| Revenue reporting | Revenue-per-wash, revenue-per-day, comparative period analysis |
| Equipment health monitoring | Motor current, pressure sensor readings, fault history |
| Remote diagnostics | Leisuwash support team can run remote fault diagnosis |
| Multi-site management | Single dashboard for operators running 2–50+ sites |
Premium Component Specification
Leisuwash’s engineering philosophy prioritizes Tier-1 global component brands over cheaper domestic alternatives, resulting in substantially longer operational life and lower total cost of ownership:
| Component | Brand |
|---|---|
| PLC Controller | Siemens (Germany) |
| Variable Frequency Drives | ABB (Switzerland/Sweden) |
| Hydraulic Pumps | Parker Hannifin (USA) |
| Bearings | NSK (Japan) |
| Motors | INNOMOTICS / Siemens (Germany) |
| Stainless Steel Frame | 304-grade food-industry standard |
| Nozzles | German precision-machined ceramic-tip |
CE Certification & International Compliance
The Leisuwash SG holds full CE marking (Machinery Directive 2006/42/EC, Low Voltage Directive 2014/35/EU, EMC Directive 2014/30/EU), enabling direct commercial deployment across all 27 EU member states and EEA countries without additional certification barriers.

11. FAQ: Leisuwash SG {#faq}
Q1: How does the Leisuwash SG compare to the Leisuwash 360?
The 360 is optimized specifically for high-throughput passenger car operations with a focus on speed and volume. The SG offers wider vehicle compatibility (accommodating taller SUVs and light commercial vehicles up to 2,350mm height), a more comprehensive standard feature set, and the modular water management options. For mixed traffic sites with a significant proportion of SUVs and light trucks, the SG is typically the better choice.
Q2: Can the Leisuwash SG wash electric vehicles (EVs)?
Yes. The SG’s touchless design and sealed electrical components make it fully compatible with EV washing. Unlike brush-based systems where spinning brushes can compress charging port covers and potentially allow water ingress, the SG’s high-pressure touchless wash poses no mechanical risk to EVs, PHEVs, or hybrid vehicles. The SG is already deployed at several Tesla-authorized service facilities in Europe.
Q3: What is the minimum water pressure requirement for the SG installation?
The site water supply must provide a minimum sustained pressure of 3 bar (43 PSI) at the machine inlet, with a flow rate capacity of at least 25 liters per minute. Below this threshold, wash performance and cycle time will be compromised. If site water pressure is below 3 bar, an optional booster pump (+$450) can be added to the installation.
Q4: Does the SG require a dedicated operator during operation?
No. Once a customer initiates a wash cycle (via coin, token, card, or app), the SG operates fully automatically from start to finish. A single attendant can monitor multiple bays while performing other tasks. Most fuel station operators report the SG adds minimal labor requirement — typically 15–20 minutes per day for chemical refilling and daily checks.
Q5: What is the expected operational lifespan of a Leisuwash SG?
With proper preventive maintenance following the Leisuwash maintenance schedule, the SG’s frame, rail system, and core mechanical components are designed for a 15–20 year operational life. The Siemens PLC, motors, and pumps are modular and can be replaced individually as they reach end-of-service life, avoiding the need for complete machine replacement.
Q6: Can the Leisuwash SG be operated in freezing temperatures?
The SG is rated for operation down to -20°C when equipped with the optional winter protection package, which includes insulated chemical lines, anti-freeze water management programming, and heated component enclosures. Units in Scandinavia, Canada, and Russia operate year-round without issue using this configuration.
Q7: How long does delivery from order to operational typically take?
For sea freight delivery, total lead time from purchase order to fully operational machine typically runs 8–12 weeks:
Air freight can reduce transit to 1 week but at significantly higher cost — typically reserved for urgent replacement units.
Q8: What chemicals does the SG require, and can I source them locally?
The SG uses standard commercial car wash chemicals available from regional suppliers globally:
Leisuwash provides recommended chemical specifications; operators are free to source equivalent products locally. Leisuwash also offers a premium own-brand chemical range optimized for SG system performance.
Conclusion: Is the Leisuwash SG Right for Your Business?
The Leisuwash SG delivers a compelling proposition for commercial operators across virtually every market segment. Its combination of Siemens-grade control technology, proven touchless wash performance, modular water management options, and 24/7 IoT monitoring — at a price 40–55% below equivalent Western competitors — makes it one of the highest-ROI investments available in the automated car wash equipment market.
