My husband had a bag of lemons on the counter, one of them was damaged at the bottom leaving mold all over the counter as you can see in the photo. Instead of spraying it I chose to vacuum it up before sanitizing. Not. There is a vent on the back of the vacuum and when I vacuumed the mold it immediately came out at the very end shooting a bunch of mold right in my face and covering the counter and floor in mold. It works great when you're vacuuming large items, but if you're planning on vacuuming something small (dust, dirt), this vacuum isn't for you.
