The Roomba 670 listings range from $50 to $85 (both used), while the Roomba 880 tested-working unit is $200. The 880 offers superior AeroForce filtration and stronger suction, justifying the premium for allergy sufferers. Among 670s, the $50 option is the best value if fully functional, though the $85 move-out sale unit may offer more buyer confidence.
