I already have 1 600 series for our downstairs. It worked okay for the 1st couple of months. My only complaint was that it was loud. After 2 months it would run out of battery before returning home and it ran in random patterns. Now I have a hard time finding the right charging point. I have to keep maneuvering it until the contact points are aligned correctly (yes, I've cleaned the contact points). On the rare occasions it returns home on its own, it can't even find the proper contact points so when I'm ready to run it another day, it isn't charged. Last year we got an i2 for our upstairs and love it. It does everything it is supposed to do and have had few problems. This year, I decided to retire the 600 series to our Bonus room level since it has a smaller cleaning area and got another 600 series for our downstairs. I was hoping maybe in 2 years iRobot would have made some improvements. Well. I ran it for the 1st time today and it is doing the EXACT same cr@p the 1st one does. Only this time, it didn't wait 2 months to do it. It is now sitting in some random spot downstairs having run out of battery before hitting home. I will be returning it and buying another i2.

As you can see from the pictures I have iRobots literally littering my house. When they work they are decent. When they don't you may as well toss them. Support is nearly non-existent. They put you through what I like to refer to as a support beatdown where they wear you down over the course of days at hours a time up to a point you don't care if it works or not. My wife and I are both Technical Architects each with 20-plus years in IT. I think we know how to add a device to wifi. When we tell them we have 4 different networks we have tried and have reset the vacuum 20 plus times and it won't connect and it has been connected how can it be a problem with our very well thought out and deployed system which has access points in every room, non-hybrid, but actually an access point for each band on separate VLANs with distinct SSIDs. Foolishness. Then when you get done with a 2 hour support call where they confirm everything you already told them then they ghost you for a week or more with no calls, emails or inkling that they even care about you as a customer. Did I mention I also have the mop? The lid broke on that in a week and won't latch down, so I have duct tape holding that together. Looks sweet for the 300 bucks I dropped. You think when you have a track record of investing thousands of dollars in a company's products they would have a minimal care in the world. Trust me iRobot does not care about its customers. They clain to have all the highest end cool features like the app quality and obstacle avoidance but does any of that make the least bit of difference if the machine won't add to the app you use to control it by? I bought a OKP vacuum on Amazon here since iRobot won't support their products for about 100 dollars and the thing was set up and working in 5 minutes and hasn't skipped a beat. Save yourself a complete nightmare and buy something that either works and doesn't require support or has support that actually cares.

UPDATE as at 9/25/23 - So following on from the previous review hereunder - the third problem was the battery which has now been replaced! Two months after the one year warranty expired, guess what? The side brush keeps falling off! This is the same thing as the first problem we had with this unit! Now the company is sending us a box to send the unit to them for repairs!!!!! Honestly this unit is absolutely awful!!!! I have been waiting for 10 days now to receive the box for the return and still haven’t got it! And I can expect it to be gone for (they say) +/- 14 days 🤦‍♀️🤦Had I written a review when I first purchased the item it would have been 5 starts! We were really excited to get this unit after doing a lot of research before purchasing the iRobot as there are a number of options available. We are a 2 person family with no children, no pets and no carpets, we have hardwood floors throughout our home. We keep all our home appliances well maintained and took great care with this unit, even purchasing replacement brushes and rollers and filters to make sure that we had them on hand when they needed to be replaced. We purchased the iRobot in July of 2022 and less than a year later, in April, had to replace the side bush module as it stopped working and the brush wouldn't spin and kept falling off. Then in May, we had to replace the main roller module as the iRobot would start its cycle and then stop completely. Honestly this is not something we expected with the iRobot. And now we are having difficulty charging, even after it returns to its base. We have cleaned the sensors on the docking station and on the unit and we keep hearing "Charge iRobot" even when it is on its base - that voice will drive you crazy! We have to keep moving the iRobot about until a connection is made and it starts charging. We are basically rebuilding the entire unit and it's not even a year old! Obviously, we're on our own when the warranty is up in July of this year!!!

Constantly gets stuck, clogged, or runs out of battery before it can crash its way back to the charger. It just randomly drives throughout the house like it's blackout drunk. Areas of a room cannot be programmed to be avoided, so furniture that is just the right height to squeeze under, but too heavy to squeeze out from under, or outlets with power cords that cannot be kept out of its way, or doors that are easy to shut all become problems as this thing smashes into them all and never finishes a job successfully.UPDATE with MORE issues that I didn't mention on the initial review: This thing appears to seek out problems to be created for you. It's very noisy, and when I happen to be around when it runs its schedule, I usually determine it's too noisy to let it continue and try to send it back to its charger. But if it's more than 5-feet from the charger or not pointed directly at it, it has no clue how to get back there. It wanders around aimlessly as if I never tried to send it back. When it gets to its charger, it has often moved it around the floor enough, pulling it away from the wall such that it will never be able to dock itself on the charger. If it runs completely out of battery, good luck getting it to charge again! It needs to be lined up ever so perfectly that it is extremely difficult to do so by hand. It practically needs to line itself up. If it's off by a millimeter it won't charge at all.Rugs are completely off limits for this worthless machine. Some I have are light enough that it tries to vacuum them up and gets them jammed into its gears. Others have patterns on them that are incompatible with its programming, somehow making it conclude that it is surrounded by cliffs, and it gets stuck on them every time never cleaning them at all.If you have certain rooms or areas of a room that you want to keep it out of because it has problems there, it is a massive headache trying to find any workable solution. Any obstacles that I try to put up it views as a challenge to be overcome, constantly smashing into them and attacking at different angles until it finds a weak spot to be exploited. Usually it gets past my best effort, but if it doesn't there is still an annoying obstacle in a passage way that I need to step around that the Roomba cannot.Finally, I would be remiss to not mention to never consider buying one of these if you intend to have a new dog in the house! On multiple occasions it has found a mess left by my dog in training before I could. It doesn't see something that's sitting an inch higher than its brushes as something to be avoided, it sees it as an enemy to be pushed around. When it comes across a fresh pile of poo, it goes over it as many times as its mechanics will allow. Smashing it down and spreading it all across the floor. Getting it mixed up into its wheels, brushes, and gears and leaving me with hours worth of cleaning of the mess it spread across the floor and within itself.If you have money to waste, get a few of these things for friends who you don't want anymore. The cruel joke will be realized soon enough and they will all stop talking to you altogether.
