If you have been waiting for an excuse to buy a robot vacuum, you will want to look at Amazon. The EufyVac X8 is one of the best mid-range models. You can purchase one for $400 instead of $600 if you take the $200 off. The X8 lacks some features that are found on more expensive robot vacuums. It does not come with a clean base. It doesn't include the mop function found on Eufy's X8 hybrid model. The X8 is an excellent value at $400 if you can do without those two features. It has four cleaning modes and four levels of cleaning. We found that the vacuum could still clean up dust and dirt even at its lowest setting. It was easy to set up, with a mobile app that offers a number of valuable features, including a tap and go feature that lets you find any spot in your home you want to clean. The RoboVac 30C is a more affordable option. It isn't as powerful as the X8 and has a less advanced navigation system, but at its current price of $170, it is hard to find a better robot vacuum.
