Its narrow working width makes it easier to clean aisles, corners and areas around fixed equipment, while the wider squeegee helps collect dirty solution behind the scrub deck.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUP TO 14,531 SQ. FT. PER HOUR:\u003c\/strong\u003e With theoretical cleaning productivity of up to 14,531 square feet per hour, the KARHDIR 350 provides an efficient alternative to manual mopping for routine commercial floor care. Actual productivity may vary depending on floor conditions, obstacles, operating speed and required overlap.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e13.78\" DISC BRUSH WITH 33.1 LB PRESSURE:\u003c\/strong\u003e The single 13.78-inch disc brush operates at 160 RPM and applies 33.1 pounds of brush pressure to loosen everyday dirt, marks and residue from compatible hard surfaces. The disc-style scrub head can be paired with a suitable brush or floor pad for different cleaning tasks.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e3.43 \u0026amp; 3.96-GALLON DUAL TANKS:\u003c\/strong\u003e A 3.43-gallon solution tank holds clean water or an approved cleaning solution, while the separate 3.96-gallon recovery tank stores collected wastewater. This separation prevents clean solution from mixing with dirty water during operation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eREMOVABLE-TANK DRAINAGE DESIGN:\u003c\/strong\u003e The removable-tank design simplifies refilling, wastewater disposal and routine rinsing. After cleaning, remove the appropriate tank and empty its contents into a suitable drain according to local disposal requirements.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e1.5–2 HOURS OF BATTERY RUNTIME:\u003c\/strong\u003e Two included 32Ah lead-acid batteries form a 24V power system that provides approximately 1.5 to 2 hours of runtime. The supplied off-board charger requires approximately 3 to 5 hours for charging under normal conditions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCOMPACT WALK-BEHIND DESIGN:\u003c\/strong\u003e The compact configuration is designed for maneuverability in smaller commercial spaces, narrow aisles and areas with fixed obstacles. Battery-powered operation provides cordless movement without restricting the operator to a nearby power outlet.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVERSATILE HARD-FLOOR CLEANING:\u003c\/strong\u003e The KARHDIR 350 is designed for compatible, water-resistant hard surfaces such as concrete, tile, marble, epoxy, PVC and terrazzo. Cleaning and water recovery performance may vary on cracked, deeply grooved or uneven flooring.\u003c\/p\u003e\n\u003ch2\u003eFeatures \u0026amp; Applications\u003c\/h2\u003e\n\u003ch3\u003eOne-Pass Scrubbing \u0026amp; Water Recovery\u003c\/h3\u003e\n\u003cp\u003eClean water or an approved low-foaming cleaning solution is delivered from the solution tank to the floor. The rotating disc brush agitates the surface to loosen dirt and residue, while the 17.7-inch rear squeegee gathers the dirty solution for recovery.\u003c\/p\u003e\n\u003cp\u003eThis integrated process allows the machine to scrub and recover wastewater in a single pass, reducing repeated cleaning and helping floors dry faster than with conventional mopping.\u003c\/p\u003e\n\u003cp\u003eFor effective water pickup, keep the squeegee clean and ensure that it maintains even contact with the floor. Uneven surfaces, deep grooves and damaged flooring may retain water and require an additional recovery pass or manual drying.\u003c\/p\u003e\n\u003ch3\u003eStepless Solution Flow Adjustment\u003c\/h3\u003e\n\u003cp\u003eThe stepless solution-flow control allows the operator to adjust the amount of water or cleaning solution delivered according to the floor condition and level of soil.\u003c\/p\u003e\n\u003cp\u003eUse only as much solution as required for effective cleaning. Reducing unnecessary water flow helps limit excess moisture, conserve clean solution and extend the working time available from each tank fill.\u003c\/p\u003e\n\u003ch3\u003eChoose the Right Brush or Floor Pad\u003c\/h3\u003e\n\u003cp\u003eDifferent floor materials and cleaning tasks may require different floor-contact accessories.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eUse a compatible disc brush for routine cleaning and suitable textured hard floors.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eUse a compatible pad driver and floor pad for maintenance cleaning, polishing, deep scrubbing or floor stripping.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSelect the pad grade according to the floor finish and required cleaning intensity.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eConfirm that the brush, pad and cleaning solution are suitable for the floor before use.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eTest the selected setup on a small, inconspicuous area when cleaning sensitive surfaces.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eSweep or vacuum the area before wet scrubbing.
