Sorry to tell you, but your bed is gross. The average mattress “can have thousands of dust mites that produce millions of droppings,” Dr. Manal Mohammed, a medical microbiologist and senior lecturer at London’s University of Westminster, told HuffPost in a previous report. These mites feed on your dead skin cells, sweat, food crumbs and sweat. Terrifying bugs aside, mattresses are also prone to mold and fungi due to their ability to hold moisture and warmth.

Per one reviewer, it’s gross-but-satisfying to see the machine in action. “I went to rinse off the filter and was shocked how much gunk came off that filter!” they wrote. “I also did all of my pillows... can’t wait to use it on the sofa!

This rechargeable handheld mattress vacuum cleaner has a UV light designed to kill germs and strong suction to grab any leftover midnight snacks. It also has a hand-washable HEPA filter and a metal screen pre-filter to minimize frequent cleaning.

Reviewer Kato says this device is a great buy, despite initial skepticism. “Honestly I thought it was a waste because we change our sheets often and i doubted the bed mattress was dirty,” they wrote. “So imagine my surprise when I used it on the mattress and tons of dirt got sucked up into the filter. It really worked. Now I am committed to using it every time we change the sheets.”
