iRobot Roomba i7+ vs IRobot Roomba i3+ Evo

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

The only con I see so far is that if it gets to far from the base and runs low on battery it may or may not make it back. Have had it for a week no and twice coming home from work I have had to return it to the base to charge. Once it was only a few feet away and didn't make it home. Please know it had just cleaned 600sqft of the 1,000sqft in 3+ hours so it's not a defective battery, but could use a software update to adjust the low power return setting

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

PRO-I like the robot as I have two hairy German Shepards and need to vacuum daily. Works well on the hardwood and tile but bunches up the hair on the carpet which isn't that big of deal to pick up. CON- Loud! It sounds like a jet engine starting up and then the noise at the end is almost unbearable. This is not my first robot and the emptying noise was not like this at all on my 1st and 2nd one but they were a different brand
