The vacuum itself is larger than average robotic vacuum which is appropriate for large room or kitchen. Very easy to use if you are new to these type of vacuum, and the led on top show you what mode it is currently running. Noise is decent, I found it pretty quiet in normal circumstances don't expect it to be unnoticeable in fully silent environment. With that said, it run pretty smooth and did not interfere my activities at all.Two of its biggest selling point for me is the ability to self-charging when it run low on juice and compatible with Alexa. You can just set it up and forget about it, but you will need the app for setup (more on it later in this review), however my tip is that you need to get the dock charger against the wall, or else the vacuum will have a hard time finding it and charge (since if you put it in the middle of the room it will keep going). I didn't find this aa a disadvantage since I prefer the dock in my corner but some may find this annoying.My floor is hardwood without carpet so I can't speak for any other types of floor, but for hardwood this stuff is phenomenal. Pick up my tiny hairs all over the place quite well. Very strong suction while considerably quiet. I don't have cords laying around but so far it is quite smarts to avoid small stuffs that I accidently laying around.What I don't really like is the app. Using it is okay, nothing fancy, but the setup is quite annoying. The app name is Smart Life - Smart Living by Volcano Technology Limited and it is a universal app, so if you're like me looking for a specific app for robotic vacuum you will be left confusing for couple mins. I decided to install the app and having a hard time get it auto scan my vacuum. Now when I went to add it manually, again this is a universal app so you have to look for the device you need and that also take me a while. Setting it up from there is okay, it's not fast but it get the job done so I won't complain about it, but remember that if you ever need to add it manually, it was in "Small Home Appliance" in Clean section.Oh and be sure to dump out the dust in the dust box every time it complete the run, or else the next time it can't suck anything. This is where I wish the dust box is a little bit larger so I can dump once every other time it finished.Overall a very nice vacuum with some nit-picking disadvantages.Edit: so I tested the app's auto-scan again and it worked fine. So while not required, you should be in a well-lit environment to get it scan correctly.
