The SEBO 300 Mechanical (Model 91303AM) is a commercial-grade upright vacuum designed for durability, simplicity, and powerful performance. Engineered entirely mechanically — with no electronics in the handle or bag housing and all electrical components located in the power head — it minimizes points of failure and simplifies maintenance.
It features a 12-inch power head with a 10½-inch cleaning path, a sturdy 1000-watt motor delivering strong airflow (106 CFM), and a large 1.4-gallon sealed bag, making it well suited for both carpeted areas and hard floors. A flat 5½-inch profile helps it reach under furniture, while the four-level manual height adjustment ensures good carpet contact.
Built-in features such as a brush obstruction indicator, automatic shut-off in case of blockages, tool-free brush strip access, and a full-bag/clog warning protect both the machine and the user. With a long 39-foot power cord, hospital-grade S-class filtration (with HEPA option), rubber-coated wheels, and warranty coverage that reflects its commercial pedigree, the 300 Mechanical delivers robust performance for demanding cleaning environments.
