Here is my review after 6 months of use. I know, you were expecting it, how and what.
I waited for a year for the price to drop on Black Friday in 2021, and indeed I got it for 499 instead of the lowest price back then, which was 699.
Meanwhile, I had seen an English review and comparison online, and I already have a Xiaomi vacuum cleaner with the attachment for mopping, which simply moves a wet cloth around the floor but works great as a vacuum cleaner.
I thought to myself, if I am so satisfied with the Chinese vacuum cleaner I bought for around 200 euros, I will be amazed by the expensive mop designed in the USA.
Unfortunately, you missed the mark.
Its basic function is okay, it does spray fresh water with detergent, and depending on the program, the strong/slow program, it makes a relative back-and-forth "scrubbing" motion. The result is good, as you can see in all the videos on YouTube.
Here is where the positives end and the disappointment begins.
1. The device is painfully slow.
For a minimal house without rugs, clutter, and furniture that touches the floor, with 4 rooms measuring 75 square meters, with a usable floor area of 43 square meters, the "good" program takes 3 and a half hours, and the "quick" one takes about 2 hours.
2. It makes more noise than you would expect from a mop:
Every time it sprays water, which is every 15-20 seconds, the motor of the pump, which is quite powerful, is activated. Also, despite the fact that the device needs to do 2 mapping runs to learn the space, it still bumps into every surface with its bumper/sensor. So, you can't sleep to save those 3 hours.
3. The software is embarrassingly bad compared to the competition.
You don't see a live map. While it mops, the program starts and you have no idea where the device is and what it has done until the program finishes (if you want to interrupt it halfway, for example).
4. It gives errors for no reason.
One of its favorites is "cover is open" even though you have closed the lid, and "fill tank with water" even though you have filled the container. Also, many times it fails to dock properly, resulting in it just sitting there without charging. The combination of these three things makes scheduling when you are away from home very problematic, as the status check happens before the program starts, not when you close the lid. So, one out of three times, the device will decide that you did something wrong and refuse to start the program. As a bonus, in all of this, if it runs out of water while mopping, it doesn't tell you and just continues with the agonizingly slow program, dragging a dry cloth around the house.
5. It tends to get stuck in certain areas (like low furniture or the base of an office chair with wheels - see photo / I also don't know how it got there) and then if it can't "get out the way it got in," it struggles for 5 minutes and then gives up until you pick it up and put it somewhere else.
Overall, it cleans okay, WHEN it doesn't get stuck for 1002 reasons, but my issue is that on one hand, it's not worth the high price it costs, especially with this software, and on the other hand, anyone who has a Xiaomi shouldn't have the illusion that iRobot is the dominant player in this field, they just have much better marketing and preferential treatment in America. It is clearly an inferior product and not worth more than 200 euros
