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

This lil guy cleans really well! And the automatic emptying is really handy compared to my old one that we have to dump out. The emptying process is incredibly loud like an airplane taking off, removed one star bc I have to cover my ears when it gets back to the base

Initially, I really thought my Roomba i4 vacuum was working as it moved flawlessly around my house seemingly cleaning my hard tile and carpeted floors. After about 10 uses, I noticed an issue where it kept telling me to empty the bag, which I didnt understand since the bag hardly had any debris in it so I thought maybe dust, dirt, or dog hair was blocking a sensor so I used microcloth and my 20yr old upright Hoover to clean any unseen dust off my Roomba i4 but this didnt rectify the issue. I then just used my 20yr old upright Hoover vacuum to clean my two SMALL rooms that were carpeted and I then confirmed that the Roomba i4 was definitely not picking up any dirt from floors as I was able to fill an entire Type Y vacuum bag with dirt, dog hair, and dust from a 10x10 sized room. At this point I returned the Roomba and Amazon (who was wonderful) sent me a replacement. The replacement immediately had a problem attaching itself to the app despite all troubleshooting; however I was able to manually push clean on the unit and it zipped around seemingly cleaning the floors. After one entire run around my 2500sq ft home, I followed immediately up with my 20yr old upright Hoover and again was able to fill a bag half full of debris that the Roomba did not pick up due to very poor suction power. I really wanted the Roomba i4 to work due to having a bad back, which makes it difficult for me to vacuum but after trying two units, which had no suction to pick up anything, I found them both defective and an expensive worthless piece of machinery! Amazon was absolutely great in assisting with my return and subsequent refund of these defective Roomba i4 units. Thank you!!

I bought this vacuum at a Black Friday price. I was skeptical when I first put it into service. It got stuck in several places in my home, but after I blocked those places the vacuum has performed very well. My home is about 2,200 square feet with a mix of tile, vinyl plank, and carpet and the vacuum handles them all well. Im glad I bought the i4 with the larger battery as the vacuum has to stop to recharge about halfway through the job, which takes about 4-4.5 hours. The cell phone app makes it easy to setup and control the vacuum, plus you can see the cleaning history including maps of each job. The edges of rugs sometimes turn up and cause the vacuum to turn in another direction, but it gets covered in another pass of the vacuum. Cleaning power is good overall, hair and larger pieces dont seem to bother it much. Overall, very pleased with my purchase!
