iRobot Roomba 675 vs iRobot Roomba i7+

And lastly, we also like that they offer very good, even coverage, even in cluttered environments. Moving on to what we dislike about the 614 and 675,...

1. It is very loud when cleaning. As both my wife and I work from home I quickly learned that it can not be run during the day because it is just too loud and distracting. I also found that I couldn't run it in the evenings as it made TV watching unbearable

The batteries stopped holding a charge after 8 months or so. I replaced them and the second set lasted vaguely half as long. I replaced them again and that set lasted only a couple of months. Additionally, at some point the bin sensor failed (so it never detected that the bin was in place), so I bypassed it with some solder

Also important to note is that the N8 will want to recharge at 15% battery, so the most you ever really get out of this thing is 85%. The next big problem for me was the design of the auto-empty base. They opted to use a dual port discharge method that sucks from 2 doors in the dust bin simultaneously. I was prompted with a firmware update right away so let that run and waited until the next day to do the initial mapping run
