Everybody who buys a PFX3S runs into the same wall about a week later. The machine cleans open carpet beautifully, and then somebody asks about the stairs. A walk-behind cannot do stairs, and it cannot do a sofa, and it cannot get into the six inches along a baseboard. This is the part that fixes that, and it is Powr-Flite’s own. This kit is for the PFX3S, and only the PFX3S Powr-Flite make a separate kit for the Prowler PFX900S and the other 100 PSI machines, because those run at a higher pressure. Ordering the wrong one is the usual mistake here. If you are not certain which machine you have, the model number is on the plate on the body — call 888-565-6163 and read it to us and we will make sure the right box leaves the building. What is in the box Flexible vacuum hose The black corrugated hose that carries the dirty water back to the machine. It coils and stores rather than kinking. Solution line The clear braided line that runs alongside it and feeds clean solution out to the tool, so both jobs happen in one hand. Upholstery hand tool The clear-headed tool at the end. Clear on purpose — you watch the water coming out and you can see when a cushion has stopped giving up dirt. A carry bag comes with it, which sounds like a small thing until you have hunted for a hand tool in the back of a van. Everything stows together with the machine. How it goes on There is nothing to fit and nothing to modify. The PFX3S is already built to take it: Pull the white cuff off the clear cover and push the accessory vacuum hose in where it was. Push the solution line onto the quick-connect at the back of the machine — the locking ring slides back to seat it and forward to release. Flip the accessory switch, which sends the power to the tool instead of the brush. Two minutes, and it goes back to a floor machine just as quickly. Why it matters A commercial extractor that cannot do stairs is half a machine in most buildings. Offices have them, rental units have them, and the customer who is paying you notices the ones you skipped. Specifications Part number PFX3S-KNS Type Upholstery and stair kit — accessory, not a machine Includes Vacuum hose, solution line, upholstery hand tool, carry bag Fits Powr-Flite PFX3S self-contained extractor Does not fit Prowler PFX900S and other 100 PSI extractors — those take PFX900S-KNS Attachment Accessory hose position plus quick-connect solution fitting on the machine Made by Powr-Flite — genuine part, not an aftermarket copy This kit or the carpet wand? These are the two ways to add hose work to a PFX3S and they are not the same job. One is for furniture and stairs, the other is for carpet the machine cannot drive over. PFX3S Upholstery Kit $331.75 The one most PFX3S owners need 500 PSI Single Jet Wand $641.99 What it is for Sofas, car seats, stair treads, edges Open carpet in rooms the machine cannot get into Hose included Yes — hose and solution line both No — wand only Ready to use out of the box Yes Needs a hose you already own Reach Hand tool, close work Full length, standing up If you own a PFX3S and nothing else, buy the kit. It is the cheaper of the two, it comes with the hose, and stairs and furniture are what a walk-behind actually cannot do. The wand is for somebody who already has hose and wants a full-length tool for carpet — and it is bought on its own because most professionals already have a hose in the van. Goes with Powr-Flite PFX3S Carpet Extractor, 3 gallon — the machine this kit is made for Powr-Flite 500 PSI Single Jet Wand — the full-length carpet wand for the same machine All carpet and steam cleaners Will this fit my Prowler PFX900S? No. The Prowler runs at a higher pressure and takes Powr-Flite’s PFX900S kit instead. Call 888-565-6163 and we will get you the right one. Do I need any tools to fit it? None. The hose pushes into the accessory position on the cover and the solution line clicks onto the quick-connect at the back. It comes off just as easily when you want the machine back on the floor. Can I use it on car interiors? Yes, that is one of the things it is best at. The hand tool is the right size for seats and the clear head lets you see when the water is running clean. Is this a genuine Powr-Flite part? Yes. Part number PFX3S-KNS, made by Powr-Flite for this machine. It is not an aftermarket kit built to fit approximately. Is the hand tool heated? No. The PFX3S is a cold water machine, so the solution reaches the tool at whatever temperature you put in the tank. Fill it with hot water from the tap if you want heat.
