I have a dust allergy among other things so someone recommended RAYCOP to me and after 2 weeks I can really feel the difference. The first photo of the dust I posted is after using it on my couch. Keep in mind that my couch already looked clean, but I wanted to see what would happen. I was a little surprised at the amount of rubbish RAYCOP was able to pick up and the second dust photo shows my sheets which have just been washed and I only slept on one night! The vacuum cleaner looks like an Apple product, which means the design is clean and surprisingly light. The suction is very good and the UV light is decent (not sure how effective it is but looks cool!) I thought I wouldn't like the power cord but it's a nice flexible long cord, that doesn't ruin the experience. So far I'm very happy with my purchase, RAYCOP has strong suction, solid build quality and is easy to use. It's also easy to clean, so I definitely feel like I'm getting quality dust and dirt cleaning every time. I think it's a solid investment in my health as my sneezing and headaches have been kept to a minimum since using RAYCOM. I am wondering if insurance will cover this as it is used to improve health? Well the bonus is clean furniture and upholstery! Thanks RAYCOP!
