Does anyone else’s bassets get easily afraid??

I was thinking of getting a robo vacuum but one of my two bassets easily scares. We have a heater that slowly turns and she barks and refuses to come into the room if it’s on. If you clap or even start sweeping for some reason she runs off. As you all know they shed so much and I have back issues so the robo vacuum would help in a huge way. My husband and me wanted to just see if anyone else has these issues with their basset.
