Over the years of using various other robot vacuums I have found there to be a few spots in my house that seemed to cause issues with cleaning efficiently and thoroughly. This section with bar stools along a wall that is also close to the area carpet has consistently been one of those areas. The skinny bar stool legs are often hard for robots to go around in a fluid and non jerky way. The Z60 has navigated this section better than any previous robot vacuum I have had and it seems to do a consistently good job. It was relatively smooth and didnt take an excessive amount of time to navigate around them all while making sure the mop was as close as possible. I have the extending mop and side reach brush turned to high frequency so that every time it does a cleaning it will maximize the cleaning around the stool legs and close to the wall moulding. Having a roller mop that extends so closely to objects and walls in particular really shows just how capable and polished this Z60 is.
