The Tapo RV30 Max Plus is our favorite cheap robot vacuum, boasting features you'd typically only find on far pricier models. In addition to its self-emptying dock, the robovac offers an impressive 5,200Pa suction power, picking up dirt and debris particularly well on hard floors. It even comes with a wide mop pad, which performs surprisingly well given it lacks active pressure application and oscillation.
