Nine meters (30 feet) beneath the waves, they found it: a vast, man-made stone wall, averaging 20 meters (66 feet) wide and two meters (6.6 feet) tall. The structure consists of some 60 massive granite monoliths, set directly onto the bedrock in pairs at regular intervals. Smaller slabs and packing stones fill in the gaps, locking the whole into a single, deliberate construction. With an estimated total mass of around 3,300 tons, this is the largest underwater structure ever discovered in France.
The Clean Navigation system of the Matrix is a marked improvement over simple robot vacuums that navigate randomly. This tech instructs the vacuum to methodically vacuum in a specific grid pattern and repeatedly passing over the same areas until all dirt and debris have been removed. Rather than rely on the hope that, over time, the robot catches all places through random movement, you enjoy deliberate coverage that systematically takes on your whole floor area one step at a time.
