Leaf Blower for fridge, water heater and furnace cleaning

We have the small but powerful Makita blower that takes a rechargeable battery. I use it blowing off sidewalks, driveway, etc. at home. And we take it camping with us. Where we camp the spaces have asphalt pads, so before we back into our space, I blow the dust and tree debris off the asphalt. Then right before I bring the slide in, I get on the roof (ladder on back of TT), and blow any dust and debris off the top of the slide out.
