Hello Dale, upgrading to electric is the smartest thing you can do. You have proprietary inlets that only Vacuflo hoses will benefit from but you can buy any new electric kit with corded hose and it will work with the system you have. However, the suction on/off benefit will not work unless you switch to industry standard inlet valves. First install an easy-to-use adaptor plate and then a new inlet. Here is the information on all that https://builtinvacuum.com/help/vacuflo/adaptor.html
. The electric kits we prefer are the Stealth and EdgeLift and here they are: https://builtinvacuum.com/electricpowered.html
. Remeber, you can use them without updating your inlets. If the suction on/off ability you really miss then you can update your inlets at a later time.
