It has it's limitations.  It is too thick to go under my living room furniture, and has problems crossing some thresholds.  It is advertised as PET HAIR robotic, and since I have two long haired dogs and one long haired cat, I felt it would be ideal for use sweeping up the animal hair when I didn't feel like using a larger vacuum.  Sadly, the animal hair wrapped around the main brush and prevented it from rotating.  Luckily, the instruction booklet addressed this matter and gave detailed information on how to disassemble part of the robotic vacuum, so I could clean out the hair, reassemble it, and get it back to working again.
