Advice on getting cat to use the litter robot?

[u/NoBee4251]

Hello! I'm looking for help on getting my boy to use the new litter box we recently got. I've kept it on sleep mode so the sifting wont scare him, he has seen our other cats use it just fine, and is able to be inside of it without a problem but he just won't use it. I've tried Dr. Elsey's cat litter attractant and that hasnt helped.

Any advice appreciated!
