The Roborock S91COP is the regional retail designation for the Roborock Saros 10R, one of Roborock’s most distinctive robots. The Saros 10R combines the Sonic Mop system for active hard floor scrubbing with the OmniGrip robotic arm: an integrated arm that reaches down from the robot’s body, picks up small objects such as cables and socks, and places them aside before they are run over or tangled into the brush. It is a genuinely useful feature in households where charging cables, small toys, and loose items regularly end up on the floor.
The mop pad on the S91COP attaches to the underside and contacts hard floors during each run. The reusable pad design means it is removed and washed between sessions, but microfibre wears gradually under that cycle: the surface texture compresses, the fibres pack down, and the friction the Sonic Mop generates against the floor declines. The household benefit of the active mopping system depends on the pads being in good condition to deliver it.
Four Plus.Parts® spare mop pads for the Roborock S91COP are included here. Each pad is sized and formed for the robot’s mopping plate, fits securely for stable contact during the vibration cycle, and is constructed from microfibre with the absorption and surface texture appropriate for this platform.
Each set is built to hold up across repeated washing without the rapid texture loss that can occur with lower-quality alternatives. Questions about your order or compatibility? We answer personally.
