How are the newer combo vacs like, especially that one I heard that handles both wet and dry and even come with scent or air tools built in, we still have the older vacs at work and I'm thinking of pitching the idea of the newer one to the higher ups but I wanna get my facts right before I make a move that may fire me lol, I've read all the readables about it but I would like to hear from people that may have had first hand experience with them, so help a brother here, and hopefully I wont be fired, stay tuned haha
