Product Description
Karcher Sensor S Commercial Upright Vacuum
The Karcher Sensor S is a dependable commercial upright vacuum designed for daily carpet cleaning in schools, offices, hotels, healthcare facilities, churches, government buildings, and other professional environments. Available in 12-inch and 15-inch cleaning widths, the Sensor S gives facilities a choice between compact maneuverability and wider floor coverage.
A single-motor design helps reduce machine weight, while manual brush-height adjustment allows operators to match the brush position to different carpet types. Electronic indicators help identify a full bag, restricted airflow, incorrect brush height, or a brush obstruction before machine damage occurs.
