Great purchase for a sticky kitty litter area
These are great.  We had a horrible problem with the kitty litter area in the bathroom.  This has wiped it out.  You can't tell we have a cat.  Some people commented in thereviews about how loud it was.  It does make a noise, but it is not distracting and it doesn't interfere with TV etc.  When the whole house is silent I can hear it in the room I'm in, but it's a white noise.
