All the attachment kits, air and electric, on this website will work with your system without any modifications. The inlets you have will be a snug fit for the hoses but if you buy any kit with a hose that has an on/off switch on the handle you can easily make the end fit perfectly into the wall inlets. If you buy an electric kit, we highly recommend the Stealth Kit
, buy one with a corded hose. When you plug the vacuum in the wall you then also plug the cord into an electrical inlet within 8-feet of the inlet. Wires are hidden in the hose for 30-feet - you only have to deal with a hose when actually vacuuming, not a cord as well. A new kit will bring life to your Broan vacuum!
