Steamin Demon II FAQ

How much water flow does the Steamin Demon II use to clean with?
Most municipal water delivery systems deliver between 4.5 and 5.5 gallons per minute (GPM). With the built-in restrictions of the Steamin Demon II, the actual flow rate usually runs between 3 and 4 GPM.

How much water pressure (PSI) does the Steamin Demon II use?
The Steamin Demon II cleans using whatever water pressure is provided by the municipal water delivery system. It varies, but typically runs between 50 and 80 PSI. But PSI alone does not tell the full story of how the Steamin Demon II cleans. More important is the Impact Rate, which measures a combination of PSI and water flow. (For more on Impact Rates, see Pressure vs. Water Flow.) 

What if the water flow (or pressure) at a job site is low?
Occasionally, the hot water tap at a job location may - either by design or because of pipe corrosion - offers restricted flow. If this occurs, turn on the cold water as well. Doing so should give you sufficient water flow of at least 3 GPM.

With all that flow, won't I quickly run out of hot water?
So long as you are cleaning in a home or facility that has a full-size hot water tank, it is very unlikely that you will run out of hot water. This is because even as you are cleaning only about one third of the time is spent with the water on. Some facilities, however, utilize miniature (3-5 gallon) hot water tanks. In this case, you will end up using tepid to cold water for much of the job. Your results will not be as good as if you had hot water to use. However, so long as you are using a good-quality prespray, and unless you are attempting to restore a really "trashed-out" carpet, you will still achieve very satisfactory results with the Steamin Demon II.

How far from a water source can the Steamin Demon II be operated? 
The standard unit can be operated up to 250 feet from a water source. For longer hose runs, an optional dual-discharge pump system is available which will allow you to operate up to 400 feet from a water source. 

What is the capacity of the discharge pump?
Depending on how much hose is attached, the discharge rate is between 4.5 and 5.5 GPM. With the optional dual-discharge pump system, the discharge rate is between 6 and 6.5 GPM.

Won't the Steamin Demon II leave the carpet wet?
No. The Steamin Demon II features an amazing recovery system that extracts over 94% of the water and will leave the carpet dryer than systems that clean using a small fraction of the water. Drying times on commercial carpet average 2-4 hours, often less. On deeper pile residential carpets, the drying time typically runs 6-8 hours. This is comparable to drying times experienced with truckmounts.

What is the CFM and water lift of the Steamin Demon II vacuum system?
The Steamin Demon II uses a three-stage Ametek-Lamb vacuum motor that is rated at 105 CFM (cubic feet of air per minute) and 118 inches of water lift. But the important thing to understand about the Steamin Demon II's vacuum system is that only 8 inches of water lift is required to move the water from the carpet to the recovery tank. This, and the size of the recovery tank (one-third cubic foot) are the keys to the incredible effectiveness and efficiency of the Steamin Demon II's vacuum system.

In terms of performance, how does the Steamin Demon II compare to other portables and to truckmounts?
In field tests that compared the Steamin Demon II to conventional portable extractors, the Steamin Demon II removed, on average, nearly 2.5 times the amount of soil; its production rate was over double that of the conventional extractors; and it removed over four times as much soil per hour of operation. The Steamin Demon II has not been tested officially against truckmounts, but in unofficial performance comparisons it seems to perform on a roughly equal level. In water damage restoration, it has been shown to outperform truckmounts in water extraction.

Can you run cleaning chemical or a rinsing agent through the Steamin Demon II?
The Steamin Demon II is designed to operate as a prespray-and-rinse extractor. The on-board prespray system features an adjustable chemical injector and recoiling prespray hose that allows you to prespray up to a 20' x 20' area. 

Can I clean stairs and furniture with the Steamin Demon II?
Yes. An optional stair and/or furniture cleaning assembly is available. It features 25 feet of vacuum and solution hose.

What about repair and maintenance?
The Steamin Demon II is designed to be a very low maintenance machine. A comprehensive, illustrated repair manual and parts list comes with each machine, and our nationwide network of factory-authorized representatives and dealers are available to solve any problems you are unable to solve yourself.

How long has the Steamin Demon II been made?
The Steamin Demon II is based on a direct hookup machine that was developed over 30 years ago. The patented "high-flow" characteristic was developed in 1996 by Mike Downey, inventor of the Steamin Demon II.

Does it matter what type of prespray and defoamer we use?
Yes. The use of a top-quality prespray and a dilute liquid defoamer are important elements in successful cleaning using the Steamin Demon II. Our own specially formulated high-flow prespray and a silicone-based dilute defoamer work extremely well.
