Roku devices, like most smart TVs and streaming boxes, can slow down over time due to ageing hardware, outdated software or a poor internet connection. Roku does not provide a dedicated "clear cache" option in its settings menu, but users experiencing sluggish performance can still clear cached data using one of three workarounds involving a system restart, which may help apps load more quickly and the interface feel more responsive.

The article explains that a hidden remote-control shortcut triggers a cache-clearing restart: pressing Home five times, Up once, Rewind twice and Fast Forward twice. Alternatively, users can navigate to Settings > System > Power > System restart, or power-cycle the device by unplugging it for around 30 seconds. This maintenance is generally only needed occasionally, such as once a month or when performance issues arise, and the piece notes it would be useful if Roku allowed clearing the cache for individual apps, as some Android TV devices do.
