While the Roomba can be a formidable vacuum cleaning robot that can rid your floors of dust, the tougher job of mopping needs a specialist. If clean, unassisted, fully automated mopping is what you are looking for, we recommend you the Braava jet Mopping Robot. Here is why we like this neat little bot. The small size enables it to manoeuvre itself to even hard-to-reach places. It doesn't harm furniture or accidentally spray walls and is intelligent enough to avoid rugs or falling off stairs.
