Over the years I have wanted a robot vacuum, but waited until my research findings allowed me to decide on a unit that was worth the money. I finally chose this unit because it vacuums, mops, self cleans (and uses hot water to self clean), air dries it’s mops after the self clean, empties out its dust bin into the base station and holds enough water to clean my entire house (1800 sq ft). This unit did not disappoint. Another thing to mention is my husband cannot take the noise of a loud noisy vacuum as he has severe tinnitus and that noise will cause it to get extreme. I was worried about just how noisy this unit would be - couldn’t find much in the reviews about noise level. Well, I am happy to report that as the vacuum is going, it is very tolerable. It is a low hum that you barely hear in the next room. The unit arrived in a rather large box, was packed well inside the box, and was easy to take out and set up. One thing to mention is you will need to download the app on your phone and connect it to your network that your phone is connected to. (I made the mistake of downloading an app that asked for a lifetime one time fee of $24.95). Turns out you don’t need that app- make sure to scan the machine’s QR code to get the free app that comes with the machine. This QR code is on the inside of the base station lid.Once I set up the machine, (note I filled the tank with plain water), I set it off to go explore the house. It mapped out my house and returned to its base. I then went on the app and labeled the rooms it mapped out and then set it off to clean the living room floor. The machine at first appeared to wander around the perimeter, but then started a methodical cleaning once it completed a perimeter run. When it found rugs or carpet, it turned off its mop feature, raised the mops and increased the suction of the vacuum. When it rolled off of the carpet it lowered the suction, lowered the mops and started the vacuum/mop feature. When it reached the end of the cleaning, it announced it was complete in its cleaning and that it would return to home.I have real wood floors, linoleum, rugs, and carpet throughout my home. The machine adapted to every surface. Only once did it get stuck under a dining room chair where it could not get out of the position. It turned itself off and announced that it was stuck and to please remove it from the jammed area.I would like to see some improvement on the app, (it would not allow me to divide a large room (that is really 2 rooms) as it says “error” tap to divide room again.The machine also has a camera, so you can record or watch what it cleans. Pretty fancy for a robot vacuum.I give this unit 5 stars as it has done everything to my expectations and I have floors that are gleaming clean.Now, if they could design one that dusts furniture (hover to tabletops lol), my cleaning experience would be perfect.I did not use any tech support so I am not rating that.One last thing to add, I bought the unit on good Friday at a great deal of 30% off. So instead of $1,500.00 I paid $1,000.00.Update: It has been a few months. I named my robot Rosie- Rosie does a great job of maintaining my floors. I start her once a week and she keeps everything gleaming. One time I accidentally left my phone charger cord hanging on the floor. I was not home while Rosie was cleaning and she sucked up the cord. She stopped and sent me a message to clear her rollers. When I got home, I found her sitting where she stopped and opened her up, pulled out my cord and cleaned some wrapped hair that was wrapped as well. I am amazed she still worked great with the end of the roller wrapped with hair. Once clean, I sent her home and restarted her. She started right up and worked perfectly. I am still thrilled with my machine.
