Although it was made to clean the dryer vent, I got it to clean the bottom of my fridge and all parts of it. It doesn't take long for a kitchen fridge to start building up a lot of dust and pet hair. This can seriously damage the compressor and cooling coils. You should clean them at least every few months or you will overheat the motor and compressors and cause problems with the fridge. It's a quick and easy alternative: get on your hands and knees, stick the brush in those crevices, and get all the dust and dirt out. Your fridge will thank you, and so will your wallet.
