Same for my j8+, it avoids cables, then asks about them in the review step.

Tell me if I made the right choice! I have a 1 floor 2.5 bed (2 bedrooms + office) 2 bath which is mostly vinyl (bathrooms are tile and my walk in closet is carpeted); live alone but have a dog who’s a massive shedder. There are transitions between the bathrooms and other rooms but not otherwise. Went with the Dreame L50 Ultra; other things I considered were the L40 Ultra AE, Roborock QRevo Edge and the Eufy E28. Currently have a Roomba j8+ which struggles with the pet hair and also doesn’t mop.

Two labs and two roombas here. J8+ is the newer one. The old fella is a 900 series and lives in the bedroom only now. His battery isn’t so good and he has trouble docking, but he’s still sucking in the most important ways.

Very. I run the J8+ twice a week and the 900 once a week. That keeps the hair in check.

I’ve had very few issues with my j8+ roomba from Costco. No mop. Self empty. Not the speediest: it covers 700 sq ft in an hour. Two cats and mostly hardwood with some flat/low pile area rugs and one plush area rug. Bag doesn’t fill for MONTHS.

I have a couple-year-old j8 that handles the downstairs. It runs daily and empties itself into the base, but I have to clean the rollers & edge brush and empty the bin & knock the dust out the filter once a week. I also have a over-ten-year-old Roomba 595 for the upstairs bedroom. That one I need to empty and de-fur after every use, but I only use it as needed (usually once a week or so). Even with the daily Roomba run, I still need to occasionally vacuum the fur tumbleweeds with the Dyson stick vacuum whenever I see them. And the house gets vacuumed with the big Dyson every other week or so.

I just returned the iRobot J8 Roomba that I bought 15 months ago. It worked fine until the last month or so. It would start a cycle and move out a few feet and then just spin in place until I paused it. I was unable to get it to start over again. I cleared it electronically and re-set it up over and over again and it just kept doing the same thing. Luckily, Costco refunded the $500ish we spent on it in June 2024. I am starting to research other brands. does anyone know about Samsung or Dyson? Thanks in advance.

I have a iRobot j8+ from Costco. Works great for my needs. It only vacuums and has auto-empty and obstacle avoidance.

We have the Roomba j8 from Costco. The first one was flaky so we went and exchanged it and the replacement has been solid
