With such an amazing list of features, there are some drawbacks which will pinch you to think for a few seconds or minutes before giving it a final call.

It does not come with a built-in camera as like one found in Roomba 980.  Shorter run time than Roomba 690 and 980. 

Noise and piercingly loud when it operates. If kids are studying or you are working it will surely cause a distraction to you. Not kind of “horrible” thing but if you are sleeping at 6’o clock in the morning it will wake you up. 

Cleaning is not so easy like other vacuum cleaners. Sometimes you may need a pair of gloves to clean it by yourself. Sometimes kitty litters it pick up have to be cleaned. 

Roomba does not efficiently clean the walls and edges. Dust may be missed by Roomba 850 and you may have to clean it manually. Roomba 850 is heavier than its previous versions.

The debris bin is small compared to other vacuum cleaners in this range. 

The charging time of the Roomba battery is little longer than its upright counterparts.

Frequently gets clogged and if not cleaned at right time, it may miss some spots in the room to clean.  

No readout notification for remaining battery life.
