content: I love it. Air cleaning machine. Not for everybody. Perfect for a small cramped house with a pet and plenty of rugs and carpet. You certainly need a garden hose with power spray to clean a water tank outside. Yes, I agree - suction is not strong, a lot of labor to operate, but if you want to remove a dust and POLLUTION from your house, it works. I was HORRIFIED yet HAPPY looking at the dirty water that I disposed after vacuuming. Happy because all dust is out, flushed to the toilet. Only after a two vacuuming, my bedrooms (including mattress and pillows)feel super fresh. The air quality improved considerably. I feel more in control of condition of my house. I am still dreaming to have a Rainbow, but for now I am cleaning with Aroma.
