In the recreational vehicle maintenance and sales sector, maintaining exemplary cleanliness in the wash bay is a top priority. Recently, the Multi PSI team was hired by the Quebec-based company Grégoire Sport to modernize its facilities and optimize its industrial cleaning processes. The goal was clear: provide robust, high-performance, and safe equipment suited to intensive daily use.
Faced with structural constraints in the building, installing a conventional rail system proved impossible. Our specialists therefore designed a custom solution based on a high-pressure washer paired with a wash boom suspended from the ceiling. This article details the engineering behind this project, the concrete benefits of this ergonomic configuration, and the key criteria for choosing an industrial wash station in Quebec.

Grégoire Sport Project: Needs Assessment and Technical Constraints
Why Choose a Suspended Wash Boom Over a Wall-Mounted or Rail System?
Preventive Maintenance for Your High-Pressure Wash Installation
A Profitable Investment for Your Shop's Operational Efficiency
Grégoire Sport, known for its expertise in the sale and maintenance of recreational vehicles, handles equipment daily that's exposed to mud, grease, and road residue. To maintain high quality standards, their wash area required high-performance equipment capable of withstanding a demanding work pace while ensuring operator safety.
During our initial site evaluation, a major challenge quickly emerged. The ceiling structure and existing configuration made it impossible to install a traditional guide rail system. Conventional rails require significant linear clearance and specific anchor points that weren't feasible in this work area.
Rather than imposing costly structural work, our experts developed an innovative alternative concept. We proposed integrating a wash boom suspended directly from the ceiling, rotating a full 360 degrees. This customized approach made it possible to work around the architectural obstacles while maximizing the coverage area of the high-pressure washer.
To meet Grégoire Sport's demanding cleanliness standards, the choice of pump and motor was critical. We selected an industrial cold-water high-pressure washer delivering a rated pressure of 2000 psi and a flow rate of 4 GPM. This precise combination provides the ideal impact to dislodge dirt without risking damage to paint or vehicle electronics.
Electrically, the unit runs on industrial 575-volt power. This voltage, common in Quebec commercial and industrial installations, ensures high energy efficiency, reduces motor overheating, and guarantees maximum durability during extended use cycles.
The centerpiece of the setup is its suspended wash boom. Measuring 9 feet in length with a drop of a few inches from the ceiling, this stainless-steel structure delivers pressurized water directly above the vehicle. The high-pressure hose no longer drags on the floor, eliminating premature wear caused by friction and equipment crushing it.
In an industrial environment, floor space management is a critical productivity factor. Hoses dragging on the floor pose a constant tripping hazard for workers and degrade quickly when stepped on or snagged by vehicles. The suspended boom permanently resolves this workplace safety issue.
Unlike a rigid wall mount that limits the range of motion to one side of the wash bay, the ceiling-mounted wash boom offers smooth 360-degree rotation. The operator can freely move around the vehicles without ever having to untangle or painfully pull the hose.
The suspended boom also outperforms rail systems in tight spaces. It requires no complex mechanical bearings prone to fouling from humidity or soapy water spray. It's a simple, highly durable solution requiring very little long-term mechanical maintenance.
Implementing this custom high-pressure cleaning station brings immediate positive results to employees' daily work. Thanks to the boom's ergonomic drop, handling the wand requires no excessive strain on the shoulders and back. This reduction in physical fatigue lowers the risk of repetitive-motion injuries.
On the operational efficiency side, the reduction in wash time is dramatic. No longer having to continually move hose reels — also known as reelers — or cables on the floor, the worker devotes their full attention to actually cleaning the equipment. The client confirmed a clear decrease in the average duration of each service.
Financially, return on investment is accelerated through preserved accessories. Guns, nozzles, and high-pressure hoses suspended from the ceiling have a significantly longer lifespan than equipment left on the floor. This translates into a direct reduction in recurring replacement and maintenance costs.

Installing a 575-volt high-pressure washer in a wet environment requires strict compliance with the Canadian Electrical Code. In a wash environment where water and electricity meet, no shortcuts are tolerated.
Every electrical component must be housed in a certified NEMA 4X watertight enclosure to withstand direct splashing, ambient humidity, and corrosion. Additionally, ground fault circuit interrupters (GFCI) rated for high voltage are mandatory to protect personnel from electrical shock.
Ensuring electrical connections are handled by a certified master electrician, combined with mechanical installation carried out by Multi PSI specialists, guarantees infrastructure that complies with the requirements of the Régie du bâtiment du Québec (RBQ) and CNESST. This ensures a safe work environment and avoids unplanned production stoppages.
To preserve your equipment's 2000 psi power and 4 GPM flow rate over the long term, a structured preventive maintenance program is strongly recommended. Even the most robust industrial systems require regular attention to maintain optimal performance.
It's recommended to check the high-pressure pump oil and the condition of the water intake filters monthly. The presence of minerals or debris in the supply water can prematurely erode the pump's valves and seals.
For the wash boom, a semi-annual inspection of the rotary fittings (swivels) and ceiling mounting points is advised. Applying suitable grease to the bearings ensures smooth boom rotation without mechanical resistance, preserving operator comfort day after day.
The setup completed at Grégoire Sport perfectly demonstrates that a custom approach can overcome any space constraint. By combining a robust 2000 psi, 575-volt high-pressure washer with a 9-foot ceiling-suspended wash boom, Multi PSI transformed a tight space into an ultra-high-performance, safe, and ergonomic cleaning station.
Ceiling-mounted or wall-mounted wash booms represent a major strategic advancement in industrial maintenance in Quebec. Their versatility, superior efficiency, and ability to raise workplace safety standards make them an essential choice for mechanical shops, dealerships, and factories. Want to optimize the productivity of your cleaning operations? Contact the Multi PSI team of experts today to design your custom wash system.
This combination offers the perfect balance of pressure and water volume. The 2000 psi dislodges stubborn grease and grime, while the 4 GPM flow rate ensures fast, effective rinsing of accumulated debris.
A suspended boom fully clears floor space, prevents hoses from being stepped on, offers 360-degree rotation around vehicles, and greatly improves employee ergonomics and safety.
Yes, our specialists custom-fit the boom's length and drop based on your ceiling clearance and the size of the equipment being washed in your bay.
575-volt power is ideal for industrial environments in Quebec. It allows very powerful electric motors to run while reducing current draw, thereby limiting motor heating during continuous use.
Absolutely. Our suspended booms and rotary fittings are built from stainless steel and high-temperature seals capable of handling hot water and cleaning chemicals.
A suspended boom pivots around a fixed central point, ideal for square wash bays. A rail system allows linear movement along the full length of the building, perfect for tractor-trailers.
We recommend integrating an automatic compressed-air purge system or installing freeze-protected water recirculation circuits to protect the pump and suspended boom during cold weather.
Maintenance is very simple: periodically inspect the upper mounting points, grease the rotary fitting bearings, and check the high-pressure seals for leaks.
Dual boom models with two independent lines are available. This allows the use of two wands, or combining degreaser application with high-pressure rinsing on the same structure.
Generally, the physical installation and technical hookup by our specialized team take one to two working days to minimize disruption to your operations.
