SEBO ET-1 (12 inches wide, 10 1⁄2-inch cleaning path) and ET-2 (15 inches wide, 13-inch cleaning path) – This model comes in two widths and has four-level manual brush height adjustment. It aggressively cleans carpets, but the brush roller may be switched off by pressing the green illuminated on/off button, so delicate rugs and hard floors can be cleaned with straight suction. Its amazing 180° steering ability provides maneuverability around furniture, and the extension side of the L-shaped head makes cleaning edges and under counters easy. It also has easy brush roller removal, a convenient clog removal door, and an orange warning light with automatic shut off for brush roller obstructions. This prevents the belt from breaking and protects the motor and carpet from damage. Its warning light also remains illuminated during use when brush height is set too high for optimal cleaning or when the brush should be replaced due to reaching maximum bristle wear.
