I have always wanted to try one of these, and I finally bit the bullet. My boyfriend has a beagle/lab/cocker spaniel mix dog with long, stiff hair that falls out like crazy. He has hard wood floors with an area carpet rug over it. He also has tile floors. I was getting very tired of constantly vacuuming, so I'm excited I have something that will do it for me. It was very easy to set up based on the instructions, and once I got it going, I probably sat there for a good half hour just staring it it in awe. The remote allows you to use the direction buttons to "Steer" the vacuum, and you can stop in a spot to spot clean - it goes around in circles and gets up any dirt. There is a bumper at the front of the vacuum that senses when it runs into things, and it automatically turns until there is a clear path. There are little rotating brushes on either side that sense things as well. You can press the home icon on the remote and the robot returns back to its charging base. I have to be honest - it takes a while to figure out where it's base is, but it does eventually find it. You can also set up a cleaning schedule. The only thing I don't like is that I don't know how long the vacuum cleans for when it is on a schedule. I watched it for 45 minutes and then sent it home because I didn't want to wear it out. The dust pan does fill up fairly quickly, so you have to empty it after every use. It's very easy to do, though. It comes with extra filters and sensor brushes, which is nice. It's easy to pull off the brushes and wheels to clean, too. There is a cool function that you can run the vacuum along a wall in a straight line. I just wish it would "see" the dirt, or learn the layout of the room so it would be a bit more efficient. Either way, I am LOVING this. I wish I could afford to buy two!

2 month update, "Suzy" as we have named our ILife, has stopped working. When it works its wonderful. This time I'm beyond annoyned, and quite frankly don't even want to try and repair it. This is crazy that within 2 months it has stopped working.

Original: So far so good. I have had this vacuum for about 3 weeks now. We have 2 golden reteivers, a cat, and 3 kids. We just recently tore up all of our carpte downstairs and put in tile floors. I knew after the first day I would need one of these. I have "suzy" (Yes I named her) run every night at 9pm. I do have to clean her out everyday especially with the dogs. It did take a little while for her to become familiar with our layout, but I think shes getting the hang of it. It is easy to clean out. She will stop when she gets stuck or clogged. She can do our whole downstairs on one battery charge, which is nice and convenient. So far so good!

I am not too sure how this item has such great reviews. It seems well built and programming and operation are very easy. It may be that my house is not a wide open space and it cannot figure out where to go. I had the A4s for nearly a month and it ran daily at 11pm for about two weeks. Yes it picked up dirt and dog fur. I could tell a difference for sure that it was cleaning some places. The biggest issue was that out of 12 days of scheduled use it only made it back to the docking station twice. I would always find it sitting somewhere discharged. The next problem is that it seems like it did not learn the floor plan of the house at all. It kept bouncing off of things at full speed making noise when the machine itself is very quiet. The proverbial straw is that I set it to clean during the day and watched it work. I started it from the base 3 times and every time it would clean a few spots for 5 minutes and then all three times it ended up stuck between an area rug and tv stand that had plenty of open space on the end.(see video) If you have a big open house, with all hard flooring and very thin area rugs? Then this may work for you. My advice is to spend a bit more if you want a robotic vac.

We've been very impressed with this plucky little machine. It works in most of the house, it picks up debris large and small, it runs quietly, and is easy to clean.

Details.

Our house is largely hardwood with rugs. The vacuum easily cleans room to room, getting stuck only 1) on the fringe of the living room/dining room rugs (sometimes able to free itself) and 2) under the cross-piece of the dining room chairs.

Those two snags mean that large room is off-limits, so we just close that door. But all else is no problem. Under beds. Around corners. Behind furniture.

We haven't spent the time to learn how to program it for regularly scheduled activations. We just press the remote control to activate it when the kitchen floor, in particular, needs cleaning up. (That's where we plugged in the recharge station. Under the kitchen table. It's not the free and open space recommended in the instructions, because we don't have such a place. But it works just fine. It took a while for the machine to navigate the table and chair legs but now it comes out of the gate like a champ.)

We have no pets in the house, but this would be a boon for keeping hair at bay.

This is an early review from about a weeks worth of use. But I do regularly update reviews with pertinent changes.
Let me preface with, I am an owner of a Neato Robot Vac for the last 4 years. It is the original XV series. I've liked it, but it had its bugs. The error message 'put my dust bin back in'.....UGH!!!!! That drove me crazy for the last 3.5 years. But the Neato did a good enough job, that I dealt with it.
We have 4 kids, so we stay busy and have little time for cleaning. Having 4 kids means we have substantial need for regular cleaning. I installed a central Vac for regular deep cleaning, but still find the need for daily robot Vacuum cleaning services. I like the robot to clean once and sometimes twice per day and we deep clean with the central Vac a few times per week. My stay at home wife, and amazing mother to our 4 children, and I share these duties, so I have an appreciation for the time and effort that goes in to floor cleaning.
The Neato got a weird error a few weeks ago. It started saying the dust bin need to be cleaned. This completely disabled it, no matter how I cleaned the dust bin and surrounding chamber. So I started shopping for robot vacs.
I have tried to add a second Neato for a while, but each one failed to be as effective as our original. So I really did not consider another Neato. I looked at several other brands, and I was a little put off by the iLife.
I figured it is too in-expensive to be effective.
I haven't heard of the brand.
How will it clean?
Finally I was intrigued by pretty good reviews, and a low profile for cleaning the under stuff. Though it won't go under our couch. But I'll be modifying the couch, it just needs to be raised an inch.
iLife wont vacuum in straight lines, If that bothers your OCD, I would look elsewhere. But I have found iLife to completely clean my floors in whatever random pattern it chooses. So if clean floors are your top goal, I can say I am pleased so far. If I were to sit and watch the little Vac clean, it may just drive me crazy watching it go all over the place, so I just set it and forget it.

So iLife it is.

I ordered it and had it all set up in minutes. The manual said charge overnight. So I planned to do that. However I set a schedule and got everything programmed. After about an hour of charging it started cleaning the house for some reason. Maybe one of my curious minions decided to play with the new toy.
Anyway, I was pleased with how quiet it was. Yet it still seemed to clean everything off our tile floor. I was a little disappointed that you must press the button for max suction each time it runs, in order to get max suction. Because we are often not at home while it is working. But after a week of running, on mostly standard suction, I can say my floors are always clean. We live in south FL. There is sand everywhere. So in addition to 4 children under age 12, we have the sand issue to deal with. If you don't vacuum at least once per day, you will get sand on your bare feet while walking around our home. For the last week I can walk around my house barefoot and my feet stay clean. I love it!! One of my compulsions, is tactile issues. The feel of gritty sand on my feet drives me a little nutty, unless I'm st the beach. Having cl an, sand free flooring eases that compulsion for me. It's actually a bigger priority than watching this vacuum travel in straight lines.
The iLife does require some maintenance. You'll need to clean the brush, especially if anyone in your household has long hair. You'll need to clean the filters as well. But these tasks are simple and relatively quick. The brush cleaning is tool-less. The filter does require a small screw driver. (Edit: 5/22, you don't need a tool. Removal of the screw is unnecessary)
I do really like the filter set up. It's three stages. It has a silk screen that keeps most large debris out of the main filter. I'll assume this is going to greatly extend the pleated paper filter life. It then has a secondary foam filter and finally a pleated paper filter. After 5 days the silk and foam filters benefited from cleaning, but the pleated paper filter still looked great. I did Vac it with the central Vac, since I had the filter all apart.
The dust bin always has a pleasing amount of debris after each vacuuming so we know it's doing a great job, clean feet not withstanding.
It has gotten stuck a few times. Twice on a loose draw string from low hanging clothing in the closet, and once under a piece of furniture. It does seem to navigate well around obstacles. Though it seems to find darker furniture more difficult to see.
It does not vacuum in long straight lines, like the Neato. But it does vacuum for nearly 2 hours. Neato was at maybe 45 minutes with fresh batteries. Neato was much louder and heavier.
We end up with clean floors, and tile does not show Vac lines, so I don't really care which path it takes. Just git 'er clean!!
ILife is quiet, but even on high suction it is much quieter on carpet, as evidenced by my video.
Time will tell how iLife holds up. But for daily vacuuming, and clean feet, I think it is an exceptional value thus far.
I would love a wifi and Alexa enabled version.

"Hey Alexa, clean the living room". Now that would be the bombdigity!!!!

Update: 7-26-17:
After a couple of months of fairly successful use, I found the robot unresponsive. I messed with it and cleaned everything. It would beep at me on the base, but refused to move. I contacted the manufacturer through their email. I let them know exactly what it was doing. Come to find out, the power switch on the side can accidentally get bumped to the off position. Ill blame one of my smaller minions! But it just as easily could have bumped into something and got switched off. So if you find your little bot a has stopped working, obviously check the power switch first! I feel a little silly, but I suppose it could happen to others.

(I paid for iLife with my own money, he was not given to me in exchange for anything, and no one has since contacted me with any sort of offer)
