How to teach your pet not to be scared of the vacuum cleaner 
Store the vacuum in an open area. 
When the vacuum cleaner is not in use, place it where your pet can easily see it. Being around the vacuum while it is not making noise should help your pet view the cleaner as something other than a threat.

[2]. Place your vacuum in a well-ventilated area of your home. Place the dishwasher at the end of the line.
[3]. Try keeping the vacuum out of reach and allow your pet to see it without fear of it swinging or moving. Keep your cat in your lap, indoors.
