Let me start by saying this: I had NO idea how dirty my mattress was until I used the Colesy Mattress Vacuum. That first use? Absolutely disgusting (in the best way possible). The amount of dust and dead skin this thing pulled out of my 'clean' mattress made me want to burn my sheets immediately.

The Good Stuff:

• Powerful Performance: The 500W motor + 16Kpa suction is no joke. It picked up layers of embedded dust that regular vacuums miss. After just two uses, my husband and I noticed fewer allergy symptoms in the morning.

• Game-Changing Features: The UV-C light + ultrasonic vibration work together to tackle dust mites. While I can't see the UV working, the heated air (140°F) definitely makes surfaces feel fresher.

• Smart Design: Love the dual-cup system that separates hair from fine dust. The 16.4ft cord is perfect for king beds, and it's surprisingly lightweight for one-handed use.

The Not-So-Good:

• Learning Curve: Press too hard and the rollers stop (blinking light alerts you). Found it works best when I let gravity do the work by gently dragging it across surfaces.

• UV Effectiveness? Doubtful - needs longer contact time than vacuuming allows to truly sanitize. But hey, nice bonus feature.

Pro Tip:

The real magic happens when you go SLOW - like glacial speed. My first pass on our 8-year-old Casper mattress filled the cup with disturbing gray powder (see photos in reviews). Three sessions later, it's still pulling up debris!

Final Verdict:

$57 well spent. Even with mattress protectors and weekly sheet changes, this revealed how much gunk accumulates over time. Works great on pet beds, couches too - though surface dog hair might need a follow-up with your regular vacuum.
