About steam cleaning in general

What is a Vapor Steam Cleaner?

A vapor steam cleaner is a cleaning machine that superheats water to produce dry saturated steam containing only 5% water. Steam cleaners can help you achieve superior cleaning results with more efficiency. Steam cleaners also have the power to sanitize, disinfect, degrease, get rid off bed bugs and allergens, and remove mold, mildew, and odors. Because steam does not require any chemicals, this process is one of the most environmentally friendly ways to deep clean and it is also safe for allergies sufferers. The specifications of the steam cleaner will depend on the type of usage and the frequency.

Why choose a vapor or a dry steam cleaner?
Why are they more expensive than regular steam cleaners?

Dry vapor steam cleaners produce a high temperature steam that contains only 5% water. Although some manufacturers will claim their carpet cleaners or carpet extractors are steam cleaners, the technology behind dry vapor steam is quite different. If the unit in question requires a lot of water, it is simply not a steam cleaner and it might results in creating mold and other humidity problems. Actual steam cleaners -such as those from Dupray- will require about 3 liters of water per hour, on average, when used continuously. As the steam contains very little water, it is completely safe for almost every surface, including carpets, upholstery, mattresses, cushions, leather and other delicate fabrics.

What pressure temperature should I look for in a decent steam cleaner?

A high-quality steam cleaner should operate at a minimum of 43 psi / 3 bar and produce steam temperatures of 303°F / 150°C or more. Don’t be fooled by low-quality steam cleaners. Although they might cost less, they are not a strategic long-term investment. A decent steam cleaner should also allow you to adjust the pressure, as more delicate tasks need less pressure. The low-pressure feature is important in getting the job done without making a mess and spraying dirt all over the place. Also, verify the quality of the accessories, boiler and casing.

What does bar mean?

A bar is a metric unit of measure for pressure used to compare the pressure power of steam cleaners. One bar is equal to 14.5 psi.

Are steam cleaners safe?

Yes. Quality steam cleaners are very safe and easy to use. Please make sure read your user guide and visit our training videos section before use. When used for it’s intended purpose, steam cleaners are safe and eco-friendly.

Can I burn myself?

While burning yourself is possible, if the instructions manual is followed, and the machine is used for it’s intended purpose and with caution, you will not get burned. Naturally, the steam jet, it’s tip and the brushes will get very hot during use.

Why are some steam cleaners so expensive?

The purchase of a steam cleaner is a long term investment. Costly units will have increased safety features, quality stainless steel boilers, heavier wiring, better quality switches, more insulation, a mounted heating unit inside the boiler, more attachments and better accessories. The machine will most likely need fewer repairs and will have a longer life span. A high-end steam cleaner will produce higher steam temperature and pressure, making your cleaning much more efficient.

When steam cleaning, where does the dirt end up?

It depends. During carpet or floor cleaning, a washable microfiber cloth is used on the accessory to insulate the steam but also to pick up dirt dislodged from the surface. Other tasks will require you to wipe off the surface afterwards, for example, when cleaning windows or grout lines.

Why should I use a steam cleaner over regular cleaning products?

For three main reasons: it's simple, efficient and ecological. Steam requires only regular tap water to clean and sanitize, which is the perfect solution for those who have allergies, those with pets and children, and for those who are sensitive to the chemical film left by some cleaning products. Steam cleaners detail all surfaces quickly and efficiently. Steam can also be used for any and all applications, meaning there would be no need to buy an endless list of cleaning products for every surface in your house or business. Steam cleaners are also a quick and precise cleaning option, able to penetrate deep into the pores of the surface and in any nooks and crannies faster than any other cleaning product.

Is it possible to clean effectively using only tap water?

Yes! When using a vapor steam cleaner, the heat produced by the steam emulsifies the grease and dirt which gets picked up by a cloth. You simply have to fill your steam cleaner with regular tap water to produce superheated steam.

About Dupray steam cleaners

How long will my Dupray steam cleaner last?

With proper maintenance and cleaning procedures, your steam cleaner can last well over 10 years.

What is the purpose of a pressure gauge?

A pressure gauge, or manometer, lets you know when the machine has reached the perfect pressure and is thus ready to use. It also indicates that the steam cleaner is working properly.

Do I have to empty the tank or boiler of my steam cleaner after each use?

No, you certainly don't have to. Simply drain the boiler (once the machine is completely cold) if you won't be using the machine for a few months. Otherwise, the only time you should empty the tank or boiler is to do a boiler drain after every approximately 30 hours of use.

Can I put chemicals in my steam cleaner?
Or add chemicals into the steam cleaning process?

Do not put anything else other than clean water inside the water tank or boiler. A steam cleaner uses only tap water to do the job and the boilers are built for water only. You can always spray a soft ecological detergent directly on the surface. Let it work a few seconds and steam clean the surface as you would normally. We recommend using natural surfactants on heavily soiled and stained carpeting to improve your cleaning. Also, some greasy areas may need some extra help from natural cleaning products.
