The market for home safety testing products is huge. You can get a simple ten dollar test for just about anything that may show up in your home like radon or mold. You can even test your water and air quality to see if there are any harmful substances floating around.
All of those testing products and nothing to test for bacteria or other harmful items on your floors or other surfaces.
I’m pretty serious about keeping things clean, but I’d love to still be able to swipe something in some areas of my floors (on carpet and hardwood) and get a reading if there’s something there which means I should do some super deep cleaning.
Put a baby’s picture on it and sell one as a nursery testing kit too, bam – billions.
