This Robat is the easiest to use just set it up with a time to start and that’s all you have to do it does the rest. I got a Samsung for Christmas a couple years back and that thing never worked I replaced it 5 times until I just give up. This Robat is a beast

This is my second Romba product. The other one no longer charges after several years of use. This one is more powerful and cleans longer. The new design solves the problem of collecting hair. The only issue based on my only use is that it may not pick up fine particles as well on tiles. Overall，I am satisfied.

This product WILL BE awesome. It was somewhat time-consuming to program, but as far as vacuuming goes, it's wonderful. Unfortunately, we're having problems with the dumping action. The company is replacing that part. We have friends with this product and they haven't had this problem. It WILL BE great.

Works great. Love the room mapping and ability to choose what room/rooms to clean

Map my floor then it went to update its self and aould never get past the update.

Step above the others, yet constantly getting errors

Returned item

Vacuum constantly gets stuck on chair bases. The vacuum climbs on top of cone shaped table and chair bases and gets stuck.

Does not work with all WiFi systems. Return to Sam’S Club (store) took forever to get the money back.

I replaced a 880 roomba with the J9+ vacumn and the difference is great! I like that it maps the whole house and then I can tell it to clean a room and it takes off and cleans that room then goes back to dock itself and emptys itself .
