Comparison HOBOT 198 vs HOBOT 268

The nominal processing time for 1 m² of glass helps assess the operating speed of a window-cleaning robot: the lower the value in min/m², the faster the pass. For example, at 2.5 min/m², a surface measuring 4 m² will require about 10 minutes, excluding a repeat cycle, repositioning the device, and preparing the cleaning cloths. Models are best compared in identical modes, since the result is affected by the route, degree of contamination, and number of passes.

The electrical power consumption reflects the load on the motor, suction fan, drives, and electronics, but does not directly measure cleaning quality. It is more appropriate to compare this figure within the same type of equipment: a more powerful device may provide greater operating capacity, but streaks and residual water are influenced more strongly by the nozzle design, the condition of the cleaning pads, and the movement algorithm. For corded models, this value also helps assess the requirements for the adapter or external power source.

Smartphone control allows you to control the window-cleaning robot through the dedicated mobile app. From your phone, you can start and stop cleaning, select a mode, change the direction of movement, and monitor the device status—the exact set of commands depends on the model. The smartphone connection can be established via Bluetooth—for direct control nearby without a router—or via Wi‑Fi, which provides a greater connection range and may support remote access over the internet.
