Yes. The Roku Simple Remote ($15), an IR device, will not work on a Roku TV. Third party Universal remotes won't either, unless it specifically says Roku TV on the packaging.
But the Roku Voice Remote ($20) will. Walmart carries them, as do Target, Best Buy, and other retailers. You can walk in and pick one up. Or you can also buy them online from Roku, Amazon, and other places.
