Bests & Worsts Reviews from Amazon

I have been looking for a cleaning robot that can do both vacuum and mopping. I was attracted by its claimed dual function. To compare I put this Noisz unit side by side with a iRobot Roomba i have. You can see this unit is about 1" smaller in diameter than Roomba. I also noticed that this unit could go under and get out of my Queen size bed without problem. My Roomba had some sticking out points on its surface which made it easier to get stuck under my bed frame. it seems to me that this unit is much more quieter than Roomba, and it could last fairly long time after each charge. I have wood floor on the first floor and low profile carpet on the 2nd floor, it worked well on both. This unit comes with a remote controller, which allows me to move it around which is useful. Virtual wall works as it is expected. After switching the dust bin to a water container, this unit sprayed some water dots along its way. limited by its water container size, it can not completely replace human mopping yet, but it is a good starting point. Overall, i think this is a good machine considering its cost and performance in comparison to competitors.
