I've tried several robot vacuums. I am impressed with this Midea product and it is absolutely worth the money. What I like: 1. I like its simple, elegant and high-tech look. Metallic gray is cool. It's a bit bigger and heavier than I expected (see attached picture). But you can tell it's well built. Midea has a good reputation as a home appliance manufacturer in China.2. It combines multiple cleaning functions including suction, sweeping and vibrating deep cleaning. In this price range it is very competitive. I tested it on carpet and tile. You can see significant differences before and after.3. It is equipped with different water flow rates for mopping floors and different suction power. You can fine-tune depending on the condition of the carpet and your needs. I like its silent mode and it can still work at night and while reading/working.4. Using AI, this vacuum cleaner can detect obstacles and either go around them or climb over them (but don't expect it to go very high). His mapping technology works well and he really gets to every corner and he remembers. You can also set specific regions and times for cleaning. Convenient voice control via Alexa and Google. Needs Improvement: App design is not that appealing. I use an iPhone and the look and feel of his app is pretty mediocre, far from pretty. Some fonts are too small. Overall, this is a great product with handy features.
