I remember years ago, someone mentioned that sometime during the cleaning process, he wanted to change over from his floor wand or a handtool. He pulled of the vacuum hose dropping it on the floor, then disconnected the pressure hose and also dropped it next to the vac hose. When out to his truck, got the handtool, went back inside, hooked everything up and began to finish cleaning.
After he was finished, he tore down packed up the truck and re-entered the customers house to hear her screaming; "Where's our pet Gerbal?!!!"
Yep,.....he found it unfortunately, deceased in his recovery tank!
Moral of this story: Always take care and think what could happen on any job.
