The Model 1739 triple brush shampooer-scrubber was made by Electrolux Corporation from circa 1993-94.  The company is now called Aerus LLC and is headquartered in Dallas, Texas with store locations throughout the USA and Canada.  You will find a free online copy of the current model of your cleaner (which is almost the same except that it doesn't have a cord winder and perhaps some other minor differences).  Go to aerusvacuums.com, click on the Support tab, then select the Download Manuals hyperlink, choose Lux Floor Pro from the Current Models menu, and click Download.  Regards.
