Bests & Worsts Reviews from Amazon

As a big "Shark" fan of past equipment I was extremely interested in the promise of "automatic" vacuuming of our condo - but put off by the $600.00+ price tag, so I opted for the refurbished version. After arrival and set-up, which was a little cumbersome, I was initially with the robot vacuum, as it worked throughout the condo. However, that initial positive perspective changed after each use - due to continual false "stops" due to the device sensing something blocking the bottom of the machine. I tried repositioning the device after inspecting the unit to insure there were no obstructions and the complete robot and discharge areas were clean. No amount of cleaning or repositioning proved effective and continually babysitting the unit completely defeated the initial purpose of purchasing the unit. Apparently, the unit had a sensor problem that became worse with use and may have been the reason for the initial return. No replacement is available from the vendor (Woot) so it will be returned for credit.
