We bought our rainbow 3 days ago and we already are loving it. It picks up so much that our other “good” vacuum missed. Also, we have a 12 yr old black lab who is usually always loudly / heavily breathing we brought her in with it running in the evening and through the night and she slept so soundly and was breathing normally. The kids asked where she was cause they couldn’t hear her loud breathing. I feel better about my baby crawling on the floor knowing how much cleaner it is.
