Apple has released watchOS 11.4 software update for all compatible Apple Watch models with Matter-compatible robot vacuum cleaners, Sleep Wake Up alarm, and a few bug fixes and security fixes.
The update was first released yesterday but quickly pulled by Apple. However, it is now available since a few hours for all compatible Watches.

Unlike previous releases, watchOS 11.4 is a relatively minor update. It features a new update to the Home app which now supports Matter-compatible robot vacuum cleaners. There are only a few compatible models available so far. Sleep Wake Up alarm is the other major features in this update which lets your alarm break through Silent mode, so you don’t oversleep.
Here are the complete release notes from Apple:
This update includes new features, improvements, and bug fixes, including:
– Matter-compatible robot vacuum cleaners can be added to the Home app as well as used in scenes, automations, or simply say “Siri, clean the living room.”
– An option to allow Sleep Wake Up alarm to break through Silent Mode
– An issue where face selection may become unresponsive when switching faces
