Charging contact plate sinks in, blocking charging; Ecovacs refuses free repair after warranty
An Italian consumer (Altroconsumo complaint board) reports the charging contact plate sank in, blocking charging; it was replaced under warranty, but mapping problems, Wi-Fi disconnections and abnormal suction/mop behaviour persisted, and once the warranty lapsed Ecovacs refused a free repair and offered only a 10% discount code.
What to check. Before buying, check the charging contact plate and whether the unit still charges reliably; note that Ecovacs' post-warranty support here was a 10% discount rather than a repair. EU market.
Fall-prevention sensor error stops cleaning; Ecovacs support unreachable for a month (Turkey)
A Turkish owner on Şikayetvar reports a persistent 'clean the fall-prevention sensor' error that stops cleaning entirely, persists after repeated cleaning, and Ecovacs support was unreachable for about a month (a WhatsApp number went unanswered for a week).
What to check. In Turkey this unit can be stopped dead by a sensor error the owner cannot clear, with very slow support response. Check the sensor area and the local service channel before buying.
Dock water-seal degradation at 12-18 months in hard-water regions; dock water leaks and nozzle clogging
Robovations' maintenance database records dock water-seal degradation at 12-18 months in hard-water regions, occasional dock water leaks (fixed by replacing the manufacturer seal kit), dock nozzle mineral clogging in hard water, and a rare mop-lift sensor malfunction that leaves pads wet on carpet.
What to check. In hard-water areas plan for seal/nozzle maintenance around 12-18 months; the dock can leak and reduce wash effectiveness. Check whether the seller covers the seal kit under warranty.
Mop mode gets lost, rinses pads but stays at dock, reports done after a quarter of the floor
A French owner reports that in mop mode the robot gets lost, often only rinses its mop pads and stays at the dock, and after returning to rinse the pads reports the task finished after covering only a quarter of the floor; a factory reset did not help.
What to check. The mop cycle can end early and leave most of the floor unmopped; a factory reset did not fix it. If mopping matters, verify the unit completes a full mop run before buying.
These reports come from the pages linked under each item: owner forums, repair guides and workshops. They are not a diagnosis of any one unit, and a careful check of the one you are buying still applies.
