I used this tool to clean heat exchangers under 3 different fridges. I had to remove the front grille on one of the three, so if this tool was a bit thinner it would probably fit under most fridges. Between the hole on the end of the tool and the hole on the side of the tool, it seems to have removed most of the dirt from under any fridge. I'm planning to use this tool to clean my tumble dryer vent but haven't done so yet.
