Dupray steam cleaner buyer’s guide.

The Ecological Cleaning Solution

Steam cleaners are incredible tools. Far superior to conventional cleaning methods, they use a combination of heat and dry steam to effectively and efficiently eliminate dirt, grease, residue, mold bacteria, viruses and germs without relying on harsh chemicals. The super heated steam sanitizes and disinfects at the same time, producing professional results in less time.

Steam has proved itself to be a powerful cleaning agent in European markets for years. Today it is entering the North American market in full force, as more and more of us are beginning to understand the sheer benefits of steam. Using nothing more than saturated dry steam which contains less then 5% water, these premium, powerful cleaning machines can clean and disinfect nearly every surface you can think of. These are without a doubt the most versatile cleaning solutions available.

Producing steam temperatures of up to 212ºC / 413ºF bacteria and germ laden surfaces can be cleaned and disinfected with a simple pass. They are also extremely effective when it comes to bedbug extermination. Dupray steam cleaners use boiling water, super heated to reach pressures up to 170psi / 12 bar and with the highest temperatures in the industry, they make for some of the best cleaning products one could ever own. Not to mention, they are completely natural. Eco-friendly and efficiency goes hand in hand at Dupray. We believe that cleaning your home at the expense of the environment is too great a cost. Although, with no need for harsh chemicals, we are able to provide an environmentally safe alternative that are also safe enough to be trusted around pets and people alike.


Eco-friendly Steam Cleaners

The Boiler

The most crucial component of a steam cleaner is the boiler. Dupray boilers are built to withstand daily use at pressures far superior to their operation effectiveness levels. Rest assured, when you’re steam cleaning with Dupray, you’re benefiting from the safest and most dependable boilers on the market. Built using only the highest quality stainless steel available for boilers and skillfully TIG welded, which is the same technique used on airplanes, they possess superior strength and dependability. We are so confident in Dupray steam boilers that we back them with a full lifetime warranty.
Hands down, the most incredible feature of Dupray steam cleaners is the impressively high temperature produced by our superior boilers. The super powerful boiler incorporates the most efficient elements on the market producing temperatures up to 212ºC / 413ºF with powerful blasting pressures of up to 12 bars / 170 psi. The incredible pressures and temperatures of these units are ultimately safe on all surfaces as there is less than 5% water contained in the steam, the perfect combination of power and precision and exceptionally efficient.

Dupray commercial-grade, portable steam cleaners such as the Hill Injection are equipped with smaller 1.5L boilers requiring much less water to produce powerful jets of steam. This translates into extremely quick start up times, allowing you to clean sooner with more efficiency, making them ideal for both residential and commercial cleaning. For the bigger jobs, Dupray industrial units like the Steam Box™ and SteamPro™ Industrial are equipped with boilers up to 14L featuring up to 10 individual heating elements, yielding some of the highest steam production ever in a portable steam cleaner.

The Replaceable Heating Elements

A heating element is a resistor and after years they naturally start to wear out and lose electrical efficiency. Where some steam cleaners necessitate an entire boiler replacement, ensures a quick servicing of the machine is all that it is needed to keep it running strong. This is increasingly important on machines that feature multiple elements where only a single element may need to be replaced.

The heating elements are also the most efficient and powerful on the market, producing 28W / cm2. This allows for smaller boilers, meaning less water will be needed to generate steam and therefore more efficiency is inevitable. Advanced technology permits the heating elements to be self-cleaning thus eliminating the risk of deposit buildup and keeping your elements in top operating condition.

The backbone of steam cleaning units.

The Continuous Steam Technology (CST™)

There are two types of Steam Cleaners. Single tank machines, which need to be refilled when empty and double tank machines, which use continuous refill technology. Smaller units such as the Tosca™ and the One™ for residential and small commercial use feature a single tank, perfect for those who only need to use their machine for short 2-hour periods at a time. All other Dupray steam cleaners are equipped with Continuous Steam Technology™. This means the user can refill the steam cleaner at any time during operation, the boiler will always have the perfect level of water for optimal steam production. All you have to do is refill the water tank while the unit is still in use to continue with your steam treatments.

The Detergent and Hot Water Injection

Some commercial grade Dupray steam cleaners come equipped with a convenient water and/or detergent injection feature. A simple touch of a button is all that is needed to reinforce your steam with some biodegradable detergent or a burst of superheated water to deep clean the treated surface. Injection technology provides extra moisture, which helps flush the dislodged dirt off of the surface, ideal for grout cleaning, bathroom cleaning, automobile detailing and more. For certain applications like gum removal or commercial kitchen cleaning, this feature is an absolute must. Once you've started using it it's impossible to go without it!

Whether it’s the Hill Injection with the water injection, the Carmen with the detergent injection or the Steam Box combining both features, you are sure to find a solution perfectly fit for your needs. Dupray also offers BIOVAP detergent, an ecological, biodegradable and nontoxic cleaning product. This extraordinarily efficient cleaning product combined with the extreme power of steam, blast away dirt and bacteria resulting in an unparalleled level of cleanliness. The powerful combination of steam jets with industrial-grade cleaning products makes light work of even the heaviest duty cleaning tasks.

Adjustable Steam Pressure

All premium quality Dupray steam cleaners, feature variable pressure technology. This allows you to select the appropriate steam pressure of between 1 bar / 20 psi and 12 bars / 170psi. They literally adapt to your cleaning application to ensure the best results without causing damage. Higher end Dupray units even come equipped with convenient fingertip pressure controls just another of our many user-friendly features that make you a more efficient cleaning pro.

The Integrated Vacuum

Dupray proudly offers built-in wet/dry vacuums to boost your cleaning power with steam extraction. The stainless steel waste collection tank is also a feature that Dupray is very proud of. After years of operating with a plastic tank, it was found that a stainless steel drum adds extra durability and heat resistance while also improving aesthetics. Steam extraction is ideal for such hevy-duty cleaning tasks as gum removal where our Carmen Super Inox steam extractor is capable of removing 700 pieces of gum per hour, residue included! Plus, the stainless steel tanks are extremely easy to clean out, extending the lifetime of the unit.

The High Steam Temperature

Steam temperature produced in the boiler is of course one of the most crucial features to be aware of when purchasing a commercial steam cleaner. A simple rule of thumb is, the higher the temperature, the more cleaning power the unit possesses. This is extremely important for applications such as removing allergens, bedbugs and bacteria as they’re extremely sensitive to heat. This is also important in terms of total sanitization and disinfection. The higher the temperature of the unit the more effective the treatment will be.

The High Steam Pressure

Steam pressure is a good indication of quality. Units with pressures less than 2 bars/29 psi are almost useless as they will certainly not have enough pressure to properly clean, sanitize or produce high enough steam temperature for disinfection. Dupray steam cleaners pressures start at 3.5 bars/50.8 psi, more than enough to deep clean and disinfect any surface.

The Overall Quality

The materials and built quality of the steam cleaner and accessories is extremely important. Dupray steam cleaners are built of materials you can trust, 100% assembled in Europe using only the most premium components. Of course the boilers in every single Dupray steam cleaner are built with high-grade stainless steel and attention to details.

Quality professional steam cleaners do not come with flimsy light plastic accessories. Those are reserved for the bottom feeders. Accessories should be molded out of premium hard plastic to be thick and durable. Fittings designed to withstand years of use at extremely high temperatures are also a good thing to consider when examining tools and accessories. Never buy a steam cleaner if you're not convinced by the quality of the accessories in your hand.

Always ensure it’s made to last.

Make sure that the steam cleaner you're looking to buy is backed by a solid warranty and service.  Dupray offers a 3-year limited warranty on its steam cleaners and a lifetime on boilers, the heart of every machine.
