eufy L50 Robot Vacuum with 4,000 Pa Powerful Suction

It was really good but stopped working a month after I bought it. Missed the return window for amazon by a week. Sent it in under warranty and the process was great and easy. I got what appeared to be a brand new l60 and was excited to have it clean again. Second l60 is terrible at mapping, constantly crashing into stuff unlike the first one that seemed to know when something is in front of it. The roller brush is also really hard to clean. One side, the plastic pops off easy and I can get the hairs out. The other side? Can't do that. I have had FOUR brushes and all have that same problem. Because you can't remove that, the hair eventually pushes the plastic so far in that it wouldn't rotate anymore and it melted due to the rotation. Had to get a whole new brush. Since it self empties I didn't think I would have to clean it every day but it's clear that you do have to. The front wheel is also impossible to pop out of the little plastic structure so cleaning is very frustrating. These two badly designed pieces make keeping it clean frustrating. RMA process went so well I was happy but I can't recommend either the l50 or l60. Badly designed brushes and the l60 just stopped working after a month when the second being awful at mapping.
