The app is incredibly slow and unresponsive. It doesn't appear to run any background services which update the status of the vacuum automatically and instead waits until you open the app; that's why it takes so damn long to load status of the vacuum unit. Notifications barely work at all. The vacuum maps my entire house but it can never find its way back to the dock; the algorithm for this feature being, "turn right until you bump into it". Firmware updates must be requested; no auto-update.
