Designed to help heavy sleepers wake up by physically moving away from the bedside, requiring the user to get out of bed to turn it off. These clocks typically feature wheels or treads that enable them to move and emit loud, persistent sounds to ensure wakefulness.​

Key Features:

• Movement: The clock autonomously rolls or jumps off the nightstand upon activation, moving around the room to prevent easy deactivation from bed.
• Audible Alerts: It produces loud beeping or ringing sounds that continue until the alarm is manually turned off, encouraging the sleeper to rise and address the noise source.
• Snooze Limitations: Many models allow only one snooze, after which the alarm will move away, ensuring the user gets up promptly.
