iRobot Roomba i4+ EVO (4552) Robot Vacuum with Automatic Dirt Disposal - Empties Itself for up to 60 Days, Wi-Fi Connected Mapping, Compatible with Alexa, Ideal for Pet Hair, Carpets

So, we bought one of these for our main floor. Had it for a few weeks, and loved it. Created a map on the first cycle, and all was good. So we bought another one for the second floor. This one was on the spectrum I think... Ran it probably 7 times, and it would not create a map. Then it started running in circles, going up and down the same area, just acting weird. Tried contacting support, useless. I put in the ticket almost two weeks ago and still havent heard back. We ended up sending it back to Amazon, and got a new unit. This one is doing much better but still had some issues. On the first couple runs, it cleaned our whole house but for some reason only created half a map. Then when it would clean, it wouldnt go any further even though the map ended right in our hallway. It would stop in the middle of the hallway and go back. Deleted the map, then had it to another everywhere run. This finally worked. So, I would recommend it but but only because the first example we bought did such a great job. Hopefully both of these dont need much support, because Im not sure support is even available given my experience... Update 11/25/2022: The 2nd floor unit has been doing pretty good. Both of our i4s have issues periodically. Sometimes they just decide they will not finish the whole floor and report back they did, or get caught on something stupid like an electric piano stand. Or, occasionally the map wont load. Overall though, they do a very good job of keeping the floors clean. (Upgrading to a 4 star rating) Most errors can be cleared by simply rebooting them. We also bought a refurbished i7 for our finished basement which is mostly carpet. The i7 is a much smarter robot, and hasnt got caught or had any problems yet. Its much more efficient at cleaning too. If you can afford the i7, it will be less hassle but the i4s generally get the job done.

Works well but is loud.

The i4+ vacuums so much better than my previous Roombas (and alternatives). It runs in logical patterns (compared to the random directions others often do), covers ground better and more efficiently, and picks up more dirt/hair/stuff than any other robo-vac that ive owned. Thats the good side. The bad side is that it doesnt always run and cant be managed. Ive had 2 other Roombas that worked great with the iRobot app, but this one does not. I can setup the vacuum, add a schedule, and then it disappears from the app. It may or may not run according to the schedule, it may run more than the schedule or it may not run at all. The app will never reconnect to the vacuum after initial setup, at least not completely. It partially connects because I can (sometimes) reboot it from the app. But it doesnt maintain a history of runs, wont on-demand, cant change the schedule, etc. Ive tried 3 different wifi networks, 3 different phones, etc, nothing works reliably. This vacuum is impossible to manage & control. Im hoping Roomba support will be helpful on this and if so will adjust review accordingly, but for now, this vacuum mostly requires manually starting it.

Having a self-emptying Roomba takes cleaning to the next level. We had a basic version but it only did an “okay” job of cleaning the floors. And we had to constantly dump it because of dog hair. The i4+ EVO does a great job of cleaning the carpet and hardwood floors AND empties itself. Having the ability to set it on a schedule and let it go is amazing. The only thing is it’s VERY loud when it’s emptying into the bag at the base. Overall I love this vacuum and may have to get another one for upstairs.

Packaging came a bit torn but that was becuase it was in a “used-very good” condition. It has never been used. Seal was still on it. This thing is doing great! Mapping is still unavailable but it just more run time to explore. This was a bargain for the price I got it for. THANK YOU ROOMBA

Love how this keeps the small stuff cleaned up and I can wrk on other things

There is a chance that I have a defective unit. I am willing to believe that. Otherwise there is no excuse for how bad this machine is. It came scratched up without me ordering a used one in a box that was almost destroyed and was barely hanging together with loads of tape on the outside. When it comes to actually cleaning it is TERRIBLE. I have a german shepherd so I do have a lot of hair to clean up. I ordered this because I wanted something that could handle the pet hair and clean itself out when it was too full. It does neither of these things. It will barely run for 5 minutes before giving an error for a blocked brush. Now, this might not be a huge issue if it would then go and clean itself out to clear up the issue, but FOR SOME REASON instead of being able to go back to its home base it just sits wherever the error happened and you have to go fetch it. What is the point of the automatic emptying if an error that can be solved by emptying it is never utilized?????? Also when it does go back it sounds like a shopvac, but I guess theres only so much you can ask for. In summation: I thought I was ordering a new device that would mean I had to empty out my vacuum a little less often and instead what I got was a used device that has required a lot more maintenance from me than the offbrand vacuum that I have been using. I may see if a replacement will solve this issue, but if not I dont really understand the point of this device.

Expectations: robot silently keeps the house clean with a 45 day auto emptying bag. Reality: noise levels are uncomfortable on hardwood or carpet. Takes an hour to clean 400 square feet, then gets tangled in hair and requires manual service. It will not set up without wifi, I spent over an hour trying to use a hotspot, it would not go though activation, so a couple times I did run it manually by pushing the button. One thing I did not hear mentioned is the NOISE, that thing is whirring, sucking and bumping into objects. It’s not pleasant to be in the same apartment while it cleans, definitely not for a work from home arrangement. What prompted me to write this review is the fact that the first ever scheduled run after connecting to wifi simply failed. I come in and find the robot dead. Later I see a notification on my phone with a cleaning instructions. I ended up taking out both brushes and cutting the hair which is tangled at both bases. Previously I cut hair from the triangular spinner. So here goes my dream of low maintenance automatic cleaning. I thought it would keep cleaning for over a month before needing my attention .The hair (over 20 inches long) is not going away. So it will keep jamming every few runs. The speed is not great, our house is mostly empty hardwood with some rugs. The history says it cleaned 400 square feet in an hour. None of the jobs ever were completed, mostly because I got tired of the noise. I moved the base station a number of times, and each map is broken, looks like I need to do another reset after finding a permanent position. Overall, mediocre. I hope the motor would not burn out due to the hair situation

yes, its loud when the house is asleep, but a welcome sight midday. weve 2 dogs & this keeps up easily. sounds like a jet taking off when it empties. easy to set-up & app makes it seamless. voice command works but name your rooms simply & distinctly. dont know why I waited so long to get one...

The Roomba i4 (4552) model is a great time saver. I give a 4 on battery life only because it has to recharge during the cleaning. However, since it works automatically, it is not an issue. My floor has a lot of obstacles which causes the Roomba to have navigation problems because it bumps into chair and table legs. If you have a lot of open space the machine will be very effective and get the job done quicker. This is a great machine that cleans well. Yes, it is loud when emptying the dirt. That is not a problem, though- it is automatic! I purchased it during an Amazon Prime Day sale and got a great deal of $399.00. If you have a floor with open spaces it will work very well and quickly. If you have lots of obstacles, it will take longer to complete the job and you may have to reset it. Overall, it is a good buy.
