Best purchase I have ever made.  With a chocolate lab running around daily, this has solved all of my problems.  I just watch shark clean every other day and mop the off days.  Absolutely love it, it has been 3 weeks of daily cleaning bliss.  I have emptied the storage weekly due to all the dog hair, but I don’t have to, I am just curious.   I used to have an early model low end robot that was a pain, this is so much more advanced and consistent- it doesn’t get stuck or leave marks on my white molding.  If I can figure out how to use this, anyone can- I am not techy at all.
