Note that the ratings and Q&A were originally for the Ace Power Head, but since the CT20 is the exact same brush but with a different name and color, we kept the information.
The CT20 Central Vacuum Power Brush features a low profile to get under most furniture and is a reliable vacuum with innovative belt that rarely brakes. It also has an overload reset, foot release, height adjustments, light, and good edge cleaning. It's "V-Belt" breaks much less than traditional cogged vacuum belts.
We kept the 485 part number online because that was the Ace number and same brush. However, when you order it you will recieve part 484 - the CT20 brush.
CT20 requires an electric hose and wand that is make to fit it (has an electrical connection on the back).
CT20 is interchangeable with and replaces all vacuums that look like the ones pictured here and replaces many vacuum heads including Ace, Hayden Super Pack, HAY202, HAY203, HAY300, HP500, all Cen-Tec CT20DXQD, CT18DXQD, CT16DX, CT14DX, Vacuflo Electroglide, AirVac VM454 & 380, M&S VM380, Nutone Broan CT600 (needs one of these lower wands), CT650, and Nutone CK350 & CK355, and and most Sears Kenmore PowerMate central vacuums and Kenmore Power Mate canisters.
