Very poor QC, but great CS
Last updated on 5/03/2024:The replacement has been working flawlessly for 5 days; if not for the lemon I get first, this x10 is almost the best mop/vac I have ever used(4 in all). It will not run into object on the way, will not go over thick cords and cannot get out, wash mop quite frequently, and make sure edges and areas around legs of furnitures are cleaned by circling around it multiple times, better than I would do. And great CS with real person answering the call with not much wait time.Update: contacted Eufy and they were quick to have a replacement on the way. I have many Eufy products, this is the first I have problem with, and it was a rare problem too, so I was willing to take a replacement instead of refund. Will update next after the replacement.I received my X10 yesterday; never had one product die on me the very first day!It was doing mapping fine last night, so I set up a daily routine to have it clean every day. This morning I heard it was going on but coming down the stairs only to find it is sitting in the middle of the kitchen floor - with no power!I tried many time to reset the connection, delete and re add the device, still coming back with the same message, error code 5021, robovac won't move at all.Totally disappointed, may want to return it even I had called and waiting for Eufy product support to find out the problem. But my experience all these years tells me, unless they send me a new one, this one will have the same problem in the future for sure.Will update the review.
