The electric kit, especially Stealth, will make a HUGE difference in cleaning and will last a very long time. The belt has a lifetime warranty! You don't need to change anything in the system, just buy any electric kit with the 8ft Cord/Pigtail option. The hose, on the wall end of it, has an attached electric cord that plugs into a nearby electrical outlet. You don't need to plug it in if you are not using the electric head and if the outlet is too far use a small extension cord. The wires are hidden in the lightweight hose. We're confident they will be very pleased. Here are the Electric Kits for Modern Day Vacuums.
