iRobot Roomba j7+ (7550) Self-Emptying Robot Vacuum –Identifies and avoids obstacles like pet waste & cords, Empties itself for 60 days, Smart Mapping, Works with Alexa, Ideal for Pet Hair, Roomba J7+

Weve owned an older Roomba, a Neato XV21 and now this Roomba J7+. Review sites adore this J7+ but I dont get it. Weve had connectivity and setup issues with it, the app is a tick above mediocre and we dont like it requiring cloud storage of photos it takes in your home to get its reviewed performance. Here are the numbers (higher is better) of the latest runs after it has had over a week to map out the house: Noise: 5 Battery Life: 9 Avoids Getting Stuck: 7 Brush Maintenance: 10 Self Emptying: 10 Smarts: 3 (if you dont care about pet poop that is, higher if you do) Cleaning Efficiency: 3 Edge / Corner Cleaning: 2 Finds Home / Self Charges: 7 Obstacle Avoidance: 5 (does avoid obstacles but is overly cautious) This robot is really blind and inefficient. It is constantly stopping short of where it should clean, only to turn around and then come back and revisit the same place over and over again. It bumps into objects hard which is antiquated at this stage of robot vacuum evolution. Ive watched this Roomba J7+ attempt to clean areas it has mapped out and it attempts to row clean areas from memory but the control systems for the wheel motors arent super precise for any of these floor robots. As a result, it will clean at an angle with respect to a toe kick / wall / edge where it should be driving parallel to it. This results in it having to have to re-clean the same areas more than once. The room mapping would be far more useful if you could set priorities for the rooms. For instance, the kitchen and hallways are more important, in our case, than the bedrooms, but the J7+ often cleans the bedrooms before more important areas. I think this is a decent robot for people that arent home when the robot is cleaning. The brushes dont appear to require any maintenance, its pretty good at finding its base and the self-emptying works well. Our base is near a gate-leg dining table and it gives this robot all kinds of trouble. It has a very hard time with the mine field of table and chair legs. Unfortunately, with a lot of people working at home, this one falls short in that scenario. It does have a good run time but its on the noisy side and is so inefficient in how it covers the floor area, that it runs and makes noise far longer than it should have to. For reference, our $300 Costco Neato was quieter and far more efficient in its cleaning patterns. It was also better at edge and corner cleaning. The review sites state that the roomba has better suction than older bots but we didnt notice any difference in cleaning. In the end, none of them are going to deep clean carpets like an upright and they all seem to clean hard floors well in our experience. Our Neato lasted maybe 6 years or so and then began intermittently failing with my vision is blocked. This evidently is due to the lidar motor / belt system wearing out so this is a vulnerability the roomba doesnt have. That said, having a robot that can see makes it so much more efficient in how it traverses the house, I can deal with replacing it every 6 years. We really dislike watching and listening to the Roomba j7+ bump into everything (and hard) after having the Neato with lidar where it can actually see where its going. Although use of a camera based, machine learning, convolutional neural network to see where its going does seem like the inevitable future of these robots (as its a big part of self-driving car tech), the Roomba J7+ evidently has a very weak system (camera, computational, ML model, etc). I think I can objectively say it uses its camera system for obstacle avoidance only and not navigation. The obstacle avoidance is overly cautious and causes the robot to miss areas it needs to clean.

This is an update: We have had this for 10 months. I still like it and it is better than the old ones, BUT it does not pick up cat litter very well. As a matter of fact I give it a poor rating in that dept. It has also ruined our wool rug. It transitions well from floor to rug but leaves dirt and debris on the rug. It has also ruined out hand knotted rug, whereas the older models didnt seem to phase it. We own 2 older Roombas. Have had them for 4 years and they just keep on going. Only had to order one battery in all that time. We have a 3 level house and it has always been a pain to drag one of the Roombas upstairs and keep a eye on the time so decided, after doing a lot of remodeling, we would get the big boy for the middle level and move one of the older ones upstairs. I read a few bad reviews but as a Roomba user for so long I can say that this model is a winner. It has no problem transitioning from my floor to wool rugs. It does make a 747 jet sound when it empties itself but it is much quieter while cleaning that my old guys.

So far so good. It is still learning how to map the house and I had to manually empty the robot on the fifth time because the bag was full.
