iRobot - i4 (4150)

I would go for a j7 all day. If you want a bare bones i4,…..I have many many many and would send one for the cost of shipping. It won’t have removable bits, but you just take off your i4 and re use. Or if your wheels are real worn, I can throw in a pair free too.

I did not score one on Vine but we scored an i4 for $130 on our local auction site for Amazon returns. We love the self emptying, the self charging, and the ai mapping with programmable jobs with the app. I am glad you are happy!

I have had several Roomba vacuums, and currently have a J7+ on main floor and an i4 in the basement. They really aren't great. Our J7 has been replaced by Roomba 2-3 times, which is great from a customer service aspect, but not great because it has needed to be replaced multiple times. In addition to full replacements, we have already had to change the battery after a little over a year. The running times to sweep our main floor have gone from a few hours to now over 6 hours. It gets lost randomly, and then finds new areas and maps them, that don't actually exist. All roombas have a pretty big design flaw, the sweeping brush pushes dirt across one of the charging leads. It will randomly stop charging, and when you look, one of the charging leads will be covered in grime and the other will be pristine. The self-empting feature is great, rarely had an issue with that. I would suggest that any robot vacuum you get be able to empty itself. The obstacle avoidance isn't great, it will often try to eat things that shouldn't. I would say approximately twice a week the vacuum is not able to finish its job and return to its base properly. It's nice to not have to worry about cleaning up all the time, especially with kids and dogs, but it is a lot of Maintenance to keep it running. We also have a brava jet mop, that has entirely stopped working. If you take it off the base it will run, but it's not able to leave its own base, which makes it a real pain. Personally, I will not be buying another Roomba.

My roomba i4 (old model) was a game changer for us! It picks up a full 2 cups of dogs hair Every. Single. Day. Our house is mostly hardwood with a couple of rugs and it does a good job navigating the changes. Add others have said: daily vacuuming is way better than weekly!

We got a refurbished Roomba i4 for $200 on Amazon and it has been awesome. Also has the self emptying can. No issues at all. Have had it for about a year now.

I’ve owned two iRobot i4’s and an iRobot Braava Jet for four years. I decided to upgrade to an iRobot Combo J9+, but wanted to be sure it was the right choice so also bought a RoboRock QRevo MaxV. I cannot emphasize enough how much better the RoboRock is in every single way compared to the iRobot. I’m absolutely a convert and will likely never consider an iRobot again unless they fully restructure their lineup and technology - which is unlikely given the current financial situation of the company.

For me, the irobot I4 series from Costco has been amazing. I did not use nor by the self emptying container. I have a St. Bernard. (I say from Costco because Costco requires vendors to upgrade their parts and increase their warranty. If you buy it from somewhere else it may not be the same.)

Just got this one today. My old one is an i4 that I've had for over 5 years now and it's starting to not clean whole areas of my floor and miss the charging station when it comes back so I figure it's time for an upgrade

I just bought an i4 for $84 from Amazon. I always get the Amazon warehouse deals on refurbished and have never had a problem. It's doing what I wanted - a good job at cleaning specific rooms of the house on demand and on a schedule. So I think it matters what you want from it. Also agree that combos are just not good generally.

All the i and j7 and below series vacuums have the same motor. Only the s9 and j9 have more suction, the s9 is actually better suction. On hard floors any of them will pick up the hair. The s9 will do very well on the area rugs. Not worth buying the combo models.
