Astro, after docking on the charger and sitting for a couple of minutes, may decide that the charge connection is not ideal. When that occurs, Astro will leave the charger and dock again. This takes less than a minute, but devices such as "Snacky" cannot depend upon Astro leaving the charger for 45 seconds as proof that a snack has been delivered.

If Astro loses the WiFi connection it can still navigate, find the charger or just "hang out."
