Comparing with my previous Samsung, for me, because it lacks power, it rather weakly. Moreover, it is not regulated in any way. Due to this, it does not always clean well. Samsung has several power modes, up to turbo. But he doesn’t build a map, so he often dulls it) It was because of the map that I took irobot, and due to the price I didn’t even think that it was so weak) in general, if I could try it live, I would still think whether to take it or not)
