"The roborock I have kicked and smashed with my foot so many times out of anger when it doesn't collaborate, and still he rocks 4-5 yrs later and no broken parts"
"I've used it daily for at least 10 years now, probably closer to 15 and apart from the fact you need to clean it periodically, it's still works like brand new."
"One huge leg up for a Shark over Roomba is that the brush roller is similar to a vacuum (e.g. hard plastic), whereas the roomba is a plastic roller with a rubber cover that is DESTROYED by dog fur and you have to frequently replace."

"I’ve seen on the camera the poor guy making multiple trips to self empty while in one room but it’s cut the hair buildup tenfold."
"With three they can just make it to a full week for emptying. ... Life changing."
"The roborock cleans the carpet so well I haven't seen or felt any litter anymore."

"splurge for the self emptying because if you have to empty it every time you're less likely to use it. We only have to empty ours like once a month and I have a 14mo and a 3yo who drop crumbs everywhere. ... we have a Shark with a large self emptying bin and that thing is great for the price point."

"I like the bag. Our bagless vacuums always made a MESS cloud of dust when trying to empty them in the kitchen. I'd have to go outside, and it would still make a cloud all over me. This was easy, close the lid on the bag, lift it out, toss it in the trash, put a new one in. It holds more than I'd typically think, because unlike our bagless, the dirt all gets packed into the bag, it gets more dense. So it holds more than you would expect."
"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."
"The nv352 is rock solid. ... My nv352 lasted almost 12 years, and it still was working, but the wheel broke off due to my own negligence. ... 6 I did was filter changes and a belt change."

"It's amazing at cleaning without getting stuck... It detects cables, socks random objects and generally doesn't get stuck."

"The fan that circulates the air is so ridiculous it sounds like an airplane is idling inside my house, and it literally changes the air pressure in my kitchen and hurts my ears"
"I don't even want to be home when my roomba is running."
"Plus they were obnoxiously loud."

"it is also way more prone to tracking pet messes about, that happened once with a pile of cat vomit and I was a little traumatized."
"if you take if off the dock yourself it loses the mop function unless you restart it literally 10 times"
"for the love of God please don get a roomba combo model. They don work… ever."

"a change in layout has confused it beyond belief."
"its lack of lidar or any type of cameras makes it wedge itself under my furniture almost every time it runs. ... It gets stuck almost every day. ... I actually considering a new one for upstairs because it s so bad by comparison."
"another that supposedly maps the space. The cheaper, random movement robot is vastly superior in all ways."

"It clogged docking because it was moist from the mopping it was doing at the same time. ... the brushes and ducting getting dirty with wet dirt."

"battery died just months after warranty expired."
"The out of warranty repair cost was 75% of what a new one would cost so I chucked it."

KhyronElric 1.0I have this one it works with no problems.
DerekDrinksHere2 0.5It 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! Roomba I3 plus
Eastern_Pangolin_309 0.5I 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.
evilsprig 0.5I 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)?
himbobflash 0.5I 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.
lucky__potato 0.5Our irobot i3+ lasted 25 months. Wasn't great when it worked either tbh
Nick6468 0.5J9+ 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+
onegianthead 0.5iRobot 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.
scalometrica 0.5Hi, 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).
Snakeberrys 0.5Adhd 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
