Description
SEBO Mechanical 350 91313AM Commercial Upright Vacuum is designed for demanding commercial environments where durability, serviceability and reliable floor-cleaning performance matter. The 350 MECHANICAL uses a wide 14-inch power head, four-level manual height adjustment, a 39-foot cord, large 1.4-gallon bag and a simple mechanical design intended to reduce electrical complexity and make maintenance easier.
Unlike many electronic uprights, the MECHANICAL series places all electrical components in the power head rather than the handle or bag housing. SEBO designed the machine this way to minimize connectors and simplify repairs, making it particularly well suited to offices, schools, churches, hotels, retail stores and other high-use environments.
SEBO Mechanical 350 91313AM Commercial-Grade Design
The SEBO Mechanical 350 91313AM is built around a deliberately simple mechanical architecture.
Its on/off switch is located directly on the power head and can be operated by foot. The external power cord can also be removed and replaced without tools, helping reduce downtime if the cord becomes damaged.
14-Inch Power Head
The 350 MECHANICAL uses a 14-inch power head with an approximately 12.5-inch cleaning path.
This wider format allows the vacuum to cover more floor with each pass than the 12-inch Mechanical 300, making it especially useful for larger commercial spaces.
The head also provides one-sided edge cleaning for walls and baseboards.
Four Manual Height Settings
The brush height can be adjusted through four settings for different carpet piles and flooring conditions.
SEBO designed the adjustment button so the tip of the cleaning wand can be used to press it while the operator remains standing upright.
Powerful 1,000-Watt Motor
The 350 MECHANICAL uses a 1,000-watt suction motor rated at approximately 106 CFM of airflow and 91 inches of water lift.
This provides strong airflow for commercial floor cleaning while keeping the machine’s design simple and serviceable.
3,200 RPM Brush Speed
The brush roller operates at approximately 3,200 RPM to agitate carpeting and loosen embedded dirt, lint, debris and pet hair.
The heavy-duty sealed brush mechanism is designed to withstand frequent use while maintaining effective carpet agitation.
Tool-Free Brush-Strip Removal
Instead of requiring full brush-roll replacement for routine maintenance, the MECHANICAL series uses a removable brush strip.
The strip can be removed without tools for cleaning hair buildup or replacing worn bristles, which can significantly simplify maintenance in commercial settings.
Automatic Brush-Obstruction Shutoff
If an object jams the brush roller, an indicator window alerts the operator, the brush stops immediately and the vacuum shuts down.
This helps protect the motor, geared belts and flooring from damage caused by obstructions.
39-Foot Commercial Power Cord
The SEBO Mechanical 350 91313AM includes a 39-foot power cord for extended cleaning range.
The long cord helps reduce outlet changes in large rooms, corridors and commercial spaces.
If the cord is damaged, its external design allows quick tool-free replacement rather than requiring extensive disassembly.
Large 1.4-Gallon Filter Bag
The 350 MECHANICAL uses a large 1.4-gallon disposable filter bag.
The large capacity reduces bag changes during long cleaning sessions and helps control operating costs in high-use environments.
A hygiene cap closes the bag opening during removal to help keep collected dust contained.
Three-Stage S-Class Filtration
The vacuum uses a three-stage filtration system consisting of a pre-motor microfilter, three-layer SEBO AeraPure bag and an S-Class exhaust microfilter.
SEBO also lists optional HEPA filtration as available for the 300/350 MECHANICAL platform.
Instant-Use Wand and Hose
An integrated cleaning wand and suction hose are always ready for above-floor cleaning.
The standard hose is approximately 6 feet long, and the wand and hose together provide about 8 feet of reach for corners, crevices, furniture and edges.
An optional 9-foot extension hose can increase total hose length to approximately 15 feet for stair cleaning.
Three Full-Size Onboard Tools
The 350 MECHANICAL comes with three onboard attachments:
- Dusting brush
- Crevice nozzle
- Upholstery nozzle
Full-Bag or Clog Indicator
If the bag becomes full, the airflow pathway becomes clogged or a microfilter becomes excessively dirty, an indicator window turns orange.
A mechanical bypass valve opens to help prevent overheating and motor damage caused by restricted airflow.
Low 6.5-Inch Profile
The vacuum reclines to an approximately 6.5-inch profile, making it easier to clean under desks, beds, tables and other furniture.
Protective Rubber-Coated Wheels
Rubber-coated wheels help the vacuum roll smoothly while protecting compatible floor surfaces.

Mechanical 350 vs. Mechanical 300
The primary difference is cleaning width. The Mechanical 300 uses a 12-inch power head with a 10.5-inch cleaning path, while the Mechanical 350 uses a wider 14-inch head with a 12.5-inch cleaning path.
For larger open areas, the 350 can clean more floor with each pass. For tighter areas and maximum maneuverability, the 300 may be preferable.
USA Vacs Expert Recommendation
At USA Vacs, we recommend the SEBO Mechanical 350 91313AM for commercial customers who value durability, easy maintenance and a wide cleaning path.
The simple mechanical architecture, replaceable external cord, removable brush strip, large bag and long 39-foot cord make this model especially practical for high-use commercial environments.
For facilities with large carpeted areas, the 14-inch power head can also improve productivity compared with narrower commercial uprights.
