Clocky Alarm Clock on Wheels

I share a bed with a deep sleeper; the alarms on an iPhone or an Alexa, or even most bedside clocks are useless. I got this hoping that a loud AF clock that rolls off the table and then proceeds to roam the room would be the thing that would finally get him moving. He set the time on the clock, then set an alarm for a few minutes away to see how it would work. The alarm went off as expected, but the volume was very lacking. We decided to try it the next morning -- maybe it would seem louder in the morning than midday. The next morning, the alarm went off *around* 8:40 am (more on this to come) and sounded like a kids' toy robot -- and not loud. It *did* roll off the bedside table, eliciting a response from the two dogs that amounted to "What was that?" but then they both went right back to sleep. Clocky proceeded to roll maybe a foot, and then just sounded its diminutive alarm. Shock -- nobody woke up to the alarm. When I did get up, I found Clocky right under the edge of the bed when I noticed the time said something like 11:05... but the alarm had gone off when it was set to; not sure what's up with that. At 9:45 am today, the time on Clocky said 1:05. So yeah, all done here with this one. There must be better options in an alarm clock -- one that alarms loudly enough to wake you up and clocks well enough to keep time.
