I am a very big fan of Ecovac. The company manufactures some of the best robot vacuums and MOP combo units, and its current flagship is Debot X9 Pro Omni. As we speak, my house is cleaning, and it does a tremendous job (Debot X8 Pro is even better than Omni, which I gave a 4-star rating).
The biggest defect of X9 is its price – it usually retails for $ 1,599. However, you can buy currently Debot X9 Pro Omani for $ 1,099 on Amazon – 31% discount from regular price.
I am now using Debot X9 Pro Omni for about a month, and I have not had to separate the brush once. I just have to do regular maintenance, such as cleaning roller MOP and other recommended cleaning tasks, to run it correctly. Otherwise, it is a complete bliss – from mapping to daily cleaning works, all this is easy.
Ecovacs have several robot vacuum and MOP combo devices on the market and it seems that each of them combines the technology given in and merge them into one. For example, it has a blast from Deebot X50 to 16,000pa Suction and Ozmo Roller Instant Self-Washing MOP from X8.
As you can expect, there are lots of AI mixed. Nevertheless, you can ignore it and use a robot vacuum such as any other (outside AI navigation and avoidance, which are important parts of functionality). Just select the kind of cleanliness you want, where you will like it, and this is the case.
At the end of the day, I can only say that I think Debot X9 Pro Omni is worth every money. While it is not cheap, it has already saved me tons of time and I look forward to avoid many more hours in the future because I continue using it to keep my house immaculate.
