Of course it has jets. Silly.
The SD is NOT like any other machine. Its concept is totally unique! It doesn't have a pump. It cleans with 2-3 gallons of water per minute. And it successfully recovers the water with a single 2-stage vac motor.
How is this accomplished? By brilliant design engineering! I'll try to explain...
Massive Amounts Of Water Without A Pump:
The SD is not a high pressure machine. It is a HIGH VOLUME machine!!! It gets hooked to a faucet and it derives its pressure from the city water source. Most cities have water pressure between 30-50 psi. The water gets sprayed into the carpet (via jets) with the full force of a garden hose!
Can you clean with 30-50 psi? Let me answer that by asking a different question. Can a fire department put out a blazing fire in a building, with just the force of 30-50 psi? They do it all day long. Picture a fire hose blasting water at a burning building. They are using just 30-50 psi of city water pressure to put out the fire. It's not the pressure that puts out the fire, it's the volume of water that gets the job done.
So there is where the SD does what it does - with volume. Imagine that you were to go behind your house and hook up a garden hose to and a spray nozzle and opened up the faucet full blast. You would be able to blast your patio clean using copious amounts of water. Envision the massive amount of water running across your patio. It isn't a pressure cleaner, but it is absolutely perfect for rinsing the patio! Now picture taking a portable extractor or even a truckmount over to your patio. Connect a carpet wand, lift up the wand - and spray water across the patio... you aren't getting much water at all!
Now you're starting to see what makes the SD unique. Water! Lots and lots of water. A limitless supply of water for rinsing the carpet. Not like anything you have ever experienced before. And all that water is produced without a pump. A unique concept, wouldn't you agree?
Recovering All That Water With A Single Wet Vac Motor:
The SD does not require a #45 Roots Blower Motor to recover the water! All that water can be recovered with a simple 2-stage vac motor. How is this accomplished? By brilliant design engineering! Again, I'll try to explain...
The vacuum chamber on the SD is very small. It probably holds about 2 quarts of water. Hmmm, pretty small you say. Yep, that's part of the trick! You fill that SMALL vac chamber half full of recovered water and what do you have? You have a vacuum chamber that operates on only about 1 quart of air volume space. Picture how the suction is transformed when you are sucking the air through such a tiny air space. A brilliant idea!
In addition to using a small air chamber to recover the water, the vacuum chamber is only about a foot from the floor. The water gets sucked through the vac shoe and up a very short distance to the miniscule high velocity vacuum chamber. A very cool design! And it works!!! The carpets are about as wet as they would be using any other typical extraction cleaning equipment. Not bad, considering that you're cleaning with 6 times more water than a typical porty.
More Stuff You Should Know:
The SD does not require filling and emptying like a porty does. There are 2 hoses that lead to the machine. The hoses and the power cord are nicely packaged together in a flexible plastic sheath. The plastic sheath keeps the 2 hoses and the power cord neat and untangled.
One hose gets hooked to directly a faucet. (The SD comes with a variety of faucet adapters to fit ANY faucet configuration you can imagine). The other hose delivers the dirty water to a toilet or drain. The recovery tank has a small pump (similar to a bilge pump) that pumps the dirty water out of the machine (via the discharge hose) as you are cleaning.
You can run 150 feet of hose with the standard SD configuration. It can also be ordered with dual discharge pumps if you intend run longer lengths of hose than 150 feet.
Does the SD have limitations? Yes it does. You are not cleaning the carpet with the agitation of high pressure. And you are not cleaning the carpet with high heat. What you are cleaning the carpet with is VOLUME! Lots and lots and lots of water!!!
The way to max out your SD cleaning is to pre-scrub the carpet with a Cimex, cylindrical brush machine, oscillating machine, etc. Then after you've provided good agitation to the carpet fiber, you can flush it like crazy using the SD.
This one-two approach provides a terrific way to provide a deep restoration cleaning!
The SD weighs about 30 pounds. It is super light and portable. It is not like any other machine on the market, in that it can produce and recover more water through the carpet than a $90,000 "big box" truckmount. Can you see why I like the SD so well?
Another place the SD excels is in rinsing rugs in a rug cleaning operation. A simple rug cleaning operation can consist of a Rug Badger, a Cimex, and a SD machine. Simple!
The SD is a very cool machine that can be used to rinse better than any other rinsing tool on the market. When you combine the BEST agitation machine (the Cimex) with the BEST rinsing tool on the market (the SD), you now have the ability to produce superb results. And it can be accomplished on the 30th floor of a building with equipment that can fit into a small closet.
The SD is a pretty special machine, wouldn't you agree?
