Of the robots up to 20 thousand, I believe that the iRobot Roomba 698 is the best option, because it costs even less than 20, and it has more features than some robots over 20. Do not get fooled by marketing, all sorts of wet cleaning. In such an inexpensive robot, it's just smearing dirt on the floor, not cleaning. As a result, he wonβt really vacuum, because the motor is low-power, and wash. And Roomba 698 is quite powerful, so it can even vacuum carpets. And he has two turbo brushes, not one, better pick up all the dirt from the floor than robots with one brush. If you donβt need some fancy functions, then this iRobot is exactly what you need, it just vacuums really well.
