Eufy Eufy X8 (Open Box)

This is going to be a 2 for 1 review. I bought my X8 back in January. It was reliable and efficient for 6 months. Suction, even on normal levels, was excellent. It picked up a surprising amount of dirt, even on what I thought was a clean floor. It really does pack the dirt into the bin allowing you to go at least a few days of running daily cleanings before emptying. Every 2-3 weeks I take it apart and blow everything out to keep it functioning perfect. On the normal setting, the noise is tolerable and you'll be able to watch tv or talk on the phone without issue. My only annoyance was that every few weeks it must get hung up on something just for a moment and it causes the map to get distorted. It doesn't really matter as far as the vacuum is concerned, but it annoyed me every time I looked at the map in the app. Overall though, performance, noise levels and function are far superior to my previous vacuum robot. Unfortunately, about 6 months in, my battery started to fail. It would run for about 20 minutes then just stop dead in it's track. I'd put it back on charge, it would power back up and show maybe 40% charge. I'd send it back out and it would stop dead again within a couple minutes. I contacted customer service and they informed me that they had no batteries in stock but I could buy one on Amazon and they'd refund the cost. However, none were available on Amazon either. I waited a few days to see if they'd show up, but no such luck. I contacted customer service again and they offered to upgrade me to the L35+. I returned my x8 and received the L35+ a few days later. I've been using the L35+ for probably 2-3 weeks now. I think your specific needs will dictate if that's an upgrade. It has mopping capabilities and also a base station with self emptying. Because of the water chamber, the dust collection bin is considerably smaller than the x8. It's not really an issue though since it's self emptying. That will require you to replace the collection bag every couple months. It also doesn't have the feature that packs the dust into the bin like the x8, but again, not really an issue. It does seem to navigate better and almost never touches a wall where the x8 did pretty frequently. It seems to have less suction power overall compared to the x8 also. I've not tried mopping with the L35+ just yet but in generally most of these robots are just dragging a wet microfiber around your house. Better than nothing, but don't expect miracles. So, overall, if you need mopping or want the self emptying feature, the L35+ is a fine machine. If you only need a vacuum and don't mind the little bit of extra maintenance, the x8 is a much better choice.
