With two labs and a cat our J6+ has been a valuable member of the family over the years. An absolute life changer, we love you Alfred, thank you for your service. (Sorry for trapping you in the bathroom)
I have an old j6+ that is a workhorse. I lightly clean it every weekend. It runs every day on hard floor surfaces. (I have a golden who sheds nonstop). I also have an s9+ for my carpeted spaces. It rarely returns to base. Inevitably I find it in the room it was supposed to be cleaning telling me the brushes need to be cleaned(they don’t). As Fire_Hunter_8413 noted, it chews those brushes up and I can never get the side brush to last longer than a week. When it does work, it vacuums extremely well. Idk why they chose such crappy brushes for it. I will have to try the hack for the brushes - I have to change them frequently because of the dog fur.
Proper maintenance by checking the underside and rollers for tangles is very important. When I got a Roborock I gave away my Roomba j6 to a family member. Within 2 weeks, they said it broke. I didn't get a chance to see the robot for another 4 months and when I took it all apart the rollers had more things wrapped around them than what could even fit in the bin. I was pretty grossed out cleaning it up. I told them I sold it for parts, when I actually got it working again.
Indeed it is. Not just for its vacuum ability, but it, and other VSLAM Roombas, are the only ones that can clean close around my round dining table pedestal. All lidar-based bots leave about a 1" gap of crumbs.
Gotta get the roomba that’s rated for pet hair.
I boarded dogs in my house for 8 years, I got one of the beefed up roombas made specifically for pet hair and it helped cut down on the daily sweeping/vacuum. Still gotta break out the big vac and do a deep clean once a week but the roomba keeps it clean enough each day that you won’t notice a ton of hair floating around. If cost me 1k but it’s been going strong for all that time.
Mine is named Optimus Grime. He’s been part of our family for 3 years. He works harder than anyone else in this household cleaning 2-3 hours per night every night on a schedule. Upkeep has been fairly inexpensive. Before bed, my husband and I pick up everything off the floor that the Mr.Grime could consider a hazard (takes maybe 3-5 minutes because kids toys), and we’re good! We have a self dumping one, which makes it really easy to set up a schedule and forget about it. It’s been a life saver considering we have 3 kids and a large dog.
