Description
Commercial office cleaners waste time clearing tangled pet hair and thread from jammed upright vacuum brush rolls. The Sanitaire SL4110A PROFESSIONAL 13″ Bagged upright vacuum prevents brush roller binding through a wide-track chevron brush roll and commercial bypass motor. It produces 115 CFM airflow and 80 inches of water lift. Hard carpet staples will snap the belt.
The main body utilizes high-impact ABS resin with a protective front bumper that shields office baseboards and desk corners. Suction originates from a 9 Amp commercial motor riding on dual sealed precision ball bearings. A heavy-duty grooved rubber belt transfers motor torque to a balanced chevron bristle brush roll. Dirty intake air passes straight into the multi-layer synthetic bag chamber, bypassing motor windings to prevent internal electrical contamination from abrasive grit.
Hardware Matrix Operational Specs
A 13-inch cleaning head covers commercial corridors in fewer passes while navigating between desks and filing cabinets. On-board stretch hose and wand attachments pull out for immediate above-floor dusting of bookshelves and HVAC grilles.
- 9 Amp commercial motor pulls 115 CFM airflow for aggressive commercial carpet extraction.
- 13-inch wide cleaning head covers office suites while maneuvering between narrow cubicle gaps.
- Multi-layer synthetic filtration bag captures 99.9 percent of dust particles down to 0.3 microns.
- Automatic carpet height adjustment compensates for changes between low loop carpet and plush pile.
- On-board stretch hose and extension wand extend reach up to 9 feet for elevated vent dusting.
- 30-foot commercial power cord reduces wall outlet changes during long corridor cleaning runs.
- Chevron bristle brush roller funnels sweepings toward the central suction intake to stop scatter.
Dyno Thermal Bench Benchmarks
A line multimeter tracks an 8.9 Amp continuous draw on a 120-volt circuit under full carpet sweep resistance. Motor armature velocity reaches 19800 RPM while the chevron brush roll spins at 3500 RPM under load. Motor casing surface temperatures climb 42 degrees Fahrenheit over room ambient after 75 minutes of continuous operation. Suction velocity holds at 115 CFM on clean bags, dropping by 15 percent when the bag packs with dirt. Sound pressure registers 70 dBA at operator height. Thermal cutouts open at 210 degrees Fahrenheit during fan stalls.
Field Maintenance Trade Offs
The single-motor belt drive shares motor torque between brush agitation and suction draw, reducing brush speed on dense shag rugs. Do not use this dry vacuum on wet bathroom floors or damp entry rugs because moisture rots the paper bag and shorts internal wiring. The 13-inch head cannot enter narrow gaps between toilet stalls.
- Replace the rubber motor drive belt every 90 days to prevent slip friction.
- Cut wound hair and threads from the brush roller ends after each work shift.
- Change the synthetic collection bag before debris reaches the upper fill line.
