Hi, excellent idea getting the central vac up and working for you. We have a brush for the TurboCat but we suggest a better upgrade if you have the money. We highly recommend an electric powered brush over the air powered TurboCat and Zoom. The carpets will never be cleaner. The air stream in the electric brush is larger and uninterupted as it is with air powered ones which spin a turbine. Can your system support a new electric hose and nozzle? Yes. You are using the same suction as before. The only difference is that the hose, at the wall end, has an 8ft electric cord that you plug into a nearby electrical outlet. The wires are hidden in the lightweight 30ft or 35ft hose so all you pull around is the hose as before. Take a look here and let us know if you have any questions https://builtinvacuum.com/electricpowered.html
. Anyhow, if you want TurboCat parts see this page https://builtinvacuum.com/parts/turbocat-parts.html
. The Manta and CentraMop are good tools. The Manta is best to homes with a lot of wood floors. The CentraMop is best for mid-week cleans in the kitchen.
