A Shark AI Robot that has become noticeably louder, or that is making a grinding, rattling or whining noise, is almost always carrying something it should not, and finding it takes a few minutes. This RV2000-series robot has a brushroll, a side brush, drive wheels, a fan motor and a self-empty base, and each has its own typical sound. A robot is naturally louder on carpet and when it picks up debris, and it is louder in a quiet house, so first note whether the noise is new, constant or only at times.
The checks in more detail
A grinding or a rattle from the underside is usually an object in the brushroll or the wheels: a small stone, a piece of Lego, a screw or a bundle of hair with grit in it. Turn the robot over, remove the brushroll and look at both ends and the housing, and spin each wheel by hand to listen for scraping.
A high whine that rises as the robot cleans suggests a blocked airway, since a fan that cannot move air spins faster; check the bin, the filter and the path to the bin, and clear any blockage. A loud buzz from the side brush may mean it is bent or has hair wrapped under it. If the noise is loudest when it empties, the self-empty base is working: it pulls the robot's bin contents into the base bag with a loud burst of suction that lasts several seconds,
which is normal, but a base that sounds laboured with a full bag or a clog needs its bag replaced and its path cleared. Wipe the wheels and sensors, replace worn brushes and check that the filter is clean and dry. A grinding that remains with a clear brushroll, clean wheels and a free fan may mean a worn bearing in a wheel or the fan motor, which SharkNinja service can check with the model series from the underside.
