The biggest difference is that the j8+ can be returned to Costco for a full refund a few months later when it doesnt work anymore.

The reason for the dust bunnies, I get them too, the rubber brushes collect static when on the rugs, and they keep balled up hair stuck to the rollers, since they r rubber and sticky, and when the roomba goes back to hard floor, the dust bunnies fall off the static roller brushes when it hits hard floor again, but I just set my roomba to do twice run over per room and I haven't found to many hair balls since I set it up that way... but yes, u will notice the hair balls just past rugs or carpet areas, my older roomba never did this, but it had the old school hair wrap brushes, so I'll take the dust bunnies over cleaning out the old style rollers any day! I hated the old style rollers! I had to clean them after every use cause I have long hair and 2 dogs that have longer hair, Australia shepherds.... so the new roomba is a huge upgrade! And I believe part of the static is more in winter cause air is dryer and static is alot worse in the winter then summer months, where I live at least... I got the j8+ cause they were the same price, and costco return policy is amazing and all the added features! One thing I hate tho. No handle on this new model roomba! And if there is a handle, I can't figure out where it is!! I loved the handle on my old roomba for moving it around from floor to floor... but I do not like not having a handle on the top of this model!

Love this unit; keeps our hardwood bare. 💪🏽

Thank you, very helpful. I wonder why they get different maps.

Thank You so much!

Good evaluation

JUST bought the j8+ for $499 from Costco. Last time I checked, which was probably a month or 2 ago, it was $699. Glad I waited lol

Has anyone figured out where to get a 4400 mAh battery replacement for the J8+? I don’t need it just yet but in a couple of years no doubt.

Question: if you put the bigger battery in de J7+, will it work correctly? (as it seems with the cuttout of the plastics of the J7+, there is room left to upgrade to a bigger capacity)

Just battery and extra bags.

sooooo J6 = normal J7 poop expert and a J8 normal poop expert - battery life -_-

I just bought my J8+ a week or two ago, but one thing i saw is that the obstacle review doesn't work... keeps saying something went wrong... edit: i fixed this problem by performing a factory reset!! yay!
