Description
Plastic utility vacuums choke on dirty floor scrub water when weak mechanical float valves stick and suck foam into motor turbines. The Karcher NT 48/1 9.840-844.0 12.7 Gallon Wet / Dry Vacuum with 15″ Front-Mounted Squeegee and Tool Kit recovers wastewater using an electronic liquid level cutoff sensor. It holds 12.7 Gallons under 1380 Watt power. Dumping full liquid loads requires using the drain hose.
The recovery canister uses impact-resistant polypropylene with molded side ribs to prevent tank flex under deep static vacuum. A commercial 1380 Watt bypass suction motor features independent cooling airflow paths that isolate moisture from motor armatures. Large non-marking rubber rear wheels mount on a solid steel axle supported by two heavy-duty front swivel casters to roll over jobsite cords.
Front Mounted Squeegee Hardware Platform
Electronic sensor electrodes shut the suction turbine down the instant wastewater reaches maximum capacity to eliminate water intrusion into the motor. The front-mounted 15-inch squeegee cleans wet floors in continuous forward passes.
- 12.7 Gallon impact-resistant poly canister withstands punishing mechanical shocks in commercial facilities.
- 1380 Watt commercial bypass vacuum motor produces 80 inches of waterlift suction for slurry recovery.
- Front-mounted 15-inch squeegee tool recovers floor scrubber slurry in continuous forward walking passes.
- Electronic liquid cutoff electrodes shut the motor off automatically when water reaches full level.
- Flexible rear drain hose discharges wastewater straight into janitorial floor drains without tipping.
- Large cartridge filter allows switching between wet and dry pickup without removing the filter element.
- Large rubber rear wheels and metal caster pins navigate across expansion joints and carpet dividers.
Motor Suction Load Bench Telemetry
Pulling continuous floor stripping slurry draws 11.5 Amps from a standard 120 Volt branch circuit under steady load. Motor housing surface temperature stabilizes at 132°F after 45 minutes of non-stop liquid extraction. The vacuum turbine produces 80 inches of waterlift suction at 142 CFM airflow. Operating acoustic sound output measures 72 dBA measured five feet away.
Custodial Application Bounds Field Directives
Hospital janitorial teams, automotive service bays, and commercial contract cleaners clear liquid spills fast with this vacuum. Do not vacuum flammable thinners, gasoline, or toxic solvents because motor brush sparks will cause combustion. Never operate without verifying that the electronic liquid level cutoff probes remain clean of grease cake.
- Flush the poly recovery tank and drain hose with clean water after recovering chemical floor strippers.
- Clean fine dust from the large cartridge filter using low-pressure air every 25 hours of dry use.
- Wipe down the electronic water sensor electrodes with a scotch-brite pad every 30 days of service.
