I had an ecovac high end AI model before this one but it has trouble auto emptying pet hair into the collection bin. The shark was able to handle this far better. That pretty much was the only positive thing about the shark. Their software is very poorly written along with their mapping and options. It’s like day and night as compared to ecovac software. The unit itself seems to get lost and repeats the same path a lot. It also will finish one room, go onto the next and then repeat a portion of the previous room again. Twice it was finished and supposed to return to base but just wondered around aimlessly until the battery was exhausted. Very disappointed in this unit. As far as the vacuuming function, it did great.
