With the Roborock E4, you can clean floors more effectively and efficiently. Each of its movements is monitored by multiple high-precision sensors. In conjunction with an internal map that outlines walls and potential obstacles, the robot recognizes where it has already been and what still needs to be cleaned. It is not only up to 10% faster but also provides a more thorough and sustainable cleaning thanks to an 11% higher suction power and double the battery performance. Combine vacuuming and mopping functions to effectively eliminate fine dust, something other vacuum cleaners may not always achieve. The app allows you to set detailed cleaning schedules for different days and even suction levels. Through gyroscopes, OpticEye motion tracking, and a shock absorber, the E4 keeps a precise eye on its movements, room edges, and obstacles. It recognizes where it has already been and can determine what still needs to be done. Since it moves up to 10% faster, it finishes cleaning more quickly. Integrated gyroscopes monitor even the slightest changes in movement angle and detect if the robot has been turned around. The easy-to-attach mopping module makes floors shine and removes fine particles that other vacuum cleaners may not always eliminate. Thanks to the innovative hydraulics of the expanded E4 mopping system, which is 28% larger, you can adjust the water output according to your cleaning preferences. The anti-tangle main brush, side brush with scratch protection, and front steering wheel help reduce hair entanglement, allowing the E4 to operate longer without interruption. Particularly large living spaces can be effortlessly cleaned with automatic recharging. The E4 recognizes when it is not yet finished. When the battery is low, it returns to the dock to recharge and then resumes cleaning from where it left off.
