This isn't a chain like great clips so it's more expensive for them to create a wait list system. They have a ticket system if a lot of people are waiting. That being said you get better quality than you would at great clips.
I never saw them clean the nozzles, but they kind of use their hands to create a seal between your hair and the nozzle
Great quality
Don't know about the vacuum nozzles. There are usually enough barbers that there isn't too much wait time
Can't answer about the vacuums. First come first served, no appointments.
