Gtech supply the cable free of charge, but we do ask you to supply your Air Ram serial number which can be found on the underside of your Air Ram. Through the Data Bridge you can also find cleaning & usage information, get support from Gtech customer support & leave feedback about your Air Ram experience. Air Ram Data Bridge requires both an Air Ram cordless vacuum & Air Ram software to be installed on your computer (PC only, minimum system requirements apply). Internet connection & email address are required to utilise full Data Bridge functionality. Note: The Data Bridge cable does not charge the Air Ram battery.
