This unit is fully functional. The only issues are:
(1) The battery does not last as long as new. The unit will dock itself more frequently to charge.
(2) The lid on the canister is currently held down by velcro to ensure a vacuum seal. Replacement lids are available new.
Along with the unit comes these additional items:
2 Extra Barrier Sensors (for a total of 3)
8 Vacuum Bags (new)
4 Filters (new)
2 Edge Sweeping Side Brushes (new)
The retail on the list of additional items alone is $240.00
