Though most of the conversation around pet hair pickup will involve how well that robot vacuum performs on carpet, pets don't stop shedding when they cross over to a hardwood or tiled floor. If your home has a pretty even split of both types of flooring, you should eye one of the best robot vacuum and mop combos for pet hair on hard floors. Strong suction power alone isn't always guaranteed to pull up every tiny strand of fur (especially fur that has blown into the corners of the room), and fine dust like pet dander and kitty litter is stubborn to be sucked up as well. In that case, a wet mopping pad using pressure to wipe is much less likely to leave finer debris behind.
