Description
Custodial staff damage expensive baseboards and furniture legs when dragging heavy uprights across hard-surface conference rooms. The Sanitaire SL3681A PROFESSIONAL 2.6 Qt. canister vacuum eliminates furniture impact trauma through a compact 10-pound wheeled chassis and multi-surface floor tools. It pulls 135 CFM airflow and 96 inches of static water lift. Ingesting standing water will short the bypass motor.
Canister tub fabrication utilizes high-density ABS polymers that flex under impacts with steel desk frames without fracturing. Inside the base, a 10 Amp 1200-watt commercial motor operates on dual sealed precision ball bearings. A balanced aluminum centrifugal fan wheel pulls vacuum pressure through a sealed multi-stage paper filter bag. Clean air bypass ports route fresh ambient air across electrical motor windings to prevent thermal saturation, exhausting warm air outward through sound-dampening acoustic side diffusers.
Hardware Matrix Operational Specs
A compact rolling canister follows operators on dual rear transport wheels and a 360-degree front castor. On-board detail attachments slip onto the chrome extension wands for quick dusting of window blinds, drapery, and HVAC vents.
- 10 Amp 1200-watt commercial motor delivers 135 CFM airflow for aggressive dry floor extraction.
- 2.6-quart collection bag holds commercial sweepings without restricting motor intake velocity.
- 10-pound lightweight canister chassis glides on rear wheels without scuffing polished floors.
- Deluxe multi-surface floor tool switches between stiff bristles for tile and smooth glides for rugs.
- Two chrome-plated steel wands provide rigid reach during overhead ceiling and vent cleaning.
- 20-foot commercial power cord reduces wall outlet transfers across executive office suites.
- 7-foot flexible suction hose resists kinking when pulled around tight partition cubicles.
Dyno Thermal Bench Benchmarks
A calibrated shop load tester records a 9.8 Amp continuous draw on a 120-volt line circuit under full working load. Motor fan velocity stabilizes at 21800 RPM under operational vacuum resistance. Sump casing surface temperatures rise 44 degrees Fahrenheit over ambient room baseline during an 80-minute continuous run. Static suction pulls 96 inches of water lift on clean filters, dropping to 82 inches when the bag fills. Sound pressure measures 71 dBA at technician ear height. High-limit thermal switches trip at 208 degrees Fahrenheit during blockages.
Field Maintenance Trade Offs
Dragging a canister tub requires operators to navigate around door thresholds to prevent the hose from catching on corners. Never assign this dry commercial vacuum to wet restroom maintenance or carpet shampoo extraction because liquid intake ruins motor windings in seconds. The 2.6-quart bag requires frequent changing on large post-construction jobs.
- Check the floor tool bristle strip for trapped hair and lint after each work shift.
- Inspect the secondary motor protection filter for dust caking every 30 run hours.
- Replace the paper filter bag when dry debris reaches the marked fill line.
