<human>: Condense the text into a few key points

This actually happend a couple of summers ago when I was working as a temp. I was suppose to clean the outside floor of a foodjoint in an amusement park. I pushed the damn thing from storage to the floor. Rolled out the power supply and water supply and connected them to the power and water source. 

I started the cleaner and started cleaning the floor. Pretty soon I noticed that the water comming out was pretty hot, nearly steaming. I didn't think much of it and started to clean the floor. After a minut or so the floor started to get a little brownish and the water started to get more and more dirtier. The hose started to feel really hot and all of a sudden it started to smell weird. I turned around and the high pressure cleaner was spewing black smoke and the plastic top was starting to boil. I dropped the hose and quickly turned of the machine. I tried to pickup the hose after but I nearly burned my hand. I tried to kick it away from the floor but part of the hose had already melted and was sticking to the floor. 

After the machine started spewing the black smoke a few of my coworkers and boss got allerted and hurried towards me. The cleaner nearly caught fire but I turned it of just in time. It turned out I hadn't properly opened the faucet the water came out of, so only a little water was going through the hose and the little amount of water was boiling inside of the cleaner.

 Due to it melting from the inside they thought it was a faulty machine while in fact it was my fault the thing melted in the first place. They didn't know because I opened the faucet full after I discovered my mistake and they arrived right after that. The machine was ruined and had to be fixed but they never suspected me.
<bot>: TIFU by melting a high pressure cleaner to the floor by not opening the water intake properly. Causing it to spew black smoke and melting the hose to the floor.
