SUBJECTCarpet Detection & Boost

The vacuum uses sensors on the bottom to detect resistance the brush meets. When the brush spins slower on carpet fibers, it signals the vacuum to increase suction and spin faster.Why does carpet detection matter for mixed-floor homes?

It saves you from manually adjusting suction between rooms, ensuring carpets get strong cleaning while hard floors don’t waste battery with unnecessary power.
