"All the parts that will have tangled hair (like rollers, empty bin, rotating brushes, and wheels) are extremely easy to remove and clean, almost with no tools needed. I literally take only ten minutes to remove every dog hair inside the system."


"We have three kids, two dogs, and a cat that sheds more than both dogs combined, and having robot vacuums has been a game changer. ... But the robot keeps the main areas of the house from getting hairballs and dirty."


"I've had my roomba for like 5 years now.. We have 3 big dogs and a cat, in a small house. Still works great, I've replaced the brushes and obviously the filters on it but it still works awesome."

"It's able to be repaired and cleaned regularly which is key to making sure it lasts a long time."


"Also, all that parts are removable and replaceable, so if one of them brokes, you can easily buy one and change it."

"I upgraded to a roomba with the self emptying thing and I love it."


"Now we have two good ones (iRobot) with the bin that they self empty into when they get full. ... Before we got the one with the bins, it would get full and need emptying before it finished a whole cycle. Now it goes and empties itself and then goes back to cleaning."


"It runs daily at 9:30 am, recharges and empties itself, then finishes rhe rest around 2 in the afternoon. ... That robot is a wonderful thing."

"However, the few times I have attempted to use the mopping feature, it has not worked well at all. ... It starts off fine, but after no more than 10 min if that, it seems to get stuck. ... What it's stuck on is beyond me because it happens in dining room each time & sounds like it's spinning it's wheels (like a car stuck in mud). ... There are no rugs, chairs are moved out of the way & there's no visible debris obstacles like one of my son's marbles or a plastic milk cap or anything. Literally just hardwood flooring. ... I've tried rebooting, I've tried popping the water/mop pad on & mopping immediately (thinking it would help reduce soaking & "puddling" near the wheels), I've tried wiping the wheels and following behind it to wipe up the drag marks of water. But it still spins & does nothing."

It works well, my dog is afraid of it so it’s hard to find a time when I can run it unless I’m at the dog park but on a schedule never works out. Don’t forget to pick up your cell phone charger cables as they can damage the rollers. Not as convenient as you would think, it works better if you move ottoman’s and small tables out of the way first, so you kind of have to prepare to run it. It does clean well overall though!

I have a Roomba i3+, and what you described with it leaving the base and returning means the charging contacts are dirty. Either on the base station or Roomba, or both. Also, if it's escaping and falling down stairs, the sensors are dirty.

I have a Roomba i3+, but a change in layout has confused it beyond belief. Any vac only with self empty with decent mapping/ navigation (such as not banging itself into the wall for 40 minutes)?

I have the Roomba i3 with tower, I think that’s around $500. It is the second unit through warranty and the new unit has had two chassis replacements. Cleans well but damn the maintenance on it has been crazy.

J9+ Combo is on Amazon for $800 right now 46% off! Great choice though many mixed reviews. The Combo Max 10 is on Amazon for $800 but I’d choose the J9+ Combo because self cleaning bases don’t actually “wash” the pads. The j9’s brown design is better than the all black in my option and the j9 has a wood top to put small plant on top for design. The j9 you can just quickly remove the pad and put in the washer I have an i3+ and Brava m6 that I’ve had for 4 years now and always worked well but I’m thinking of upgrading to a combo j9+

iRobot i3+. Literally a tank. Ran it three times a week for over three years. Over 1000 hours and 300,000 sqft of cleaned area. Replaced the battery for $50 and was still running fine… until it ate poop. Twice. Finally decided it was time to upgrade to a S1 Pro. Might clean up the i3 and retire it to garage duty.

r/RobotVacuumsBest Robot Vacuum for Pet Hair Now
about 1 year ago

Hi, i have one german shepard and one labrador, both of them have long hair and a lot of shredding almost half of year. I recently bought my first robot vacuum and after researching a lot i went with an iRobot Roomba i3+. I am very satisfied with it but i will give you some points to have in mind first: - For pet hair rollers must not have brushes because its problematic. - You will need to pass it every day to avoid big bricks of pet hair. - Self emptying dock is a must if you have pets. - You should do quick maintenace (no more than 5-15 min) to the robot at least one day per week. Knowing that, i am very happy with the Roomba because it goes great with all of that. Beside of that, some things that i really liked about this brand is that: - All the parts that will have tangled hair (like rollers, empty bin, rotating brushes, and wheels) are extremely easy to remove and clean, almost with no tools needed. I literally take only ten minutes to remove every dog hair inside the system. - Also, all that parts are removable and replaceable, so if one of them brokes, you can easily buy one and change it. - Dust bag in dock compresses very hard the hair, so every bag will last you like a month. - They have tons of video tutorials in their official youtube channel for cleaning and maintaing every single model of their brand. - App is simply great, it haves a nice user interface and user experience. This Roomba i3 doesnt have extremly powerful suction, but it is more than sufficient for pets hair. Sometimes for other things (for example some heavy food crumbs) it doesnt catch them. But if you go for higher series (5,7,9) i understand that they have better suction. I have not tested other brands so i cant tell you if there are any better, but i am really satisfied with this Roomba. This is my honest review and i hope it can help you to pick a Robot Vacuum. I picked mine reading tons of comments from this subreddit. Happy new year for everyone and sorry for my bad english, i am Argentinian! 👍

Hi! The i3 still doing it excellent. I definitly recommend this model. I am not really sure what is going on with iRobot company, i read a few days ago that they have made bad decisions on their lastest models and they are close to bankrupcy or something like that haha, but i keep reading comments of people with classic models (like series I/J) and they still happy with them. The app keeps nice and without errors (at least for my use).

Adhd here with two cats. When I first got my roomba i3 plus I was amazed at just how much weight off ones shoulders robot vacuums can relieve, the braava mop was also nice.... but eventually I started seeing flaws and in my new place they struggled with thresholds and then I heard of roomba going bankrupt So I decided to bite the bullet and got the curv s5x and it is also an amazing upgrade! Just the lidar alone is such an upgrade (besides not being able to go under my couches skirt)  People can complain/make fun of how everything is smart/automated now a days but for a lot of people it can make all the difference
