The vacuums, as well as the location, all turn off at 8pm during summer hours (March - October) and at 7pm during winter hours (October - March). To answer your question, they are currently turning off at 8pm.
8pm summer hour's.
Primeshine closes at 8pm so I think they would shut the vaccumes off 15 mins b4 closing. Thats just my guess u might want to call PrimeShine to get more information.
