Comparison HOBOT 2S vs HOBOT 298

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

The noise level indicates how loud the window cleaner operates: the lower the value, the more comfortable the device is to use indoors. Models quieter than 60 dB are comparable in volume to a calm conversation, the 60 – 65 dB range is already clearly audible, while devices above 65 dB may interfere with work or relaxation nearby. A robot produces sound throughout the entire cycle, whereas a handheld vacuum makes noise only while directly collecting water.
