My gen 1 started ignoring magnetic stripes. Brought to IMM service center but they could not repair feel abit wasted to buy new one but leh zeh to build my own barridcades/close doors everytime wanna vacuum
Didn't try magnetic strip, don't like it on the ground. Usually just use chair to barricade kitchen entrance.
S5 is reasonably good for it's price, s6 have minimal improvement over it at least to my usage.
