£140 to £200, depending on condition and whether accessories are included. The RoboVac X8 retails around £319 new; used discounts of 35 to 55% are common and reflect appropriate depreciation.
Yes for hard floors and low-pile carpets. Our bench test scored it 7.6/10 — honest value at the price, with strong suction data but limited performance on thick carpet. At £150 to £180 used it is one of the most affordable entry points for lidar-navigation robot vacuums.
