C7 Walk-Behind Floor Scrubber

Product Information

22" CLEANING WIDTH & 31.5" SQUEEGEE WIDTH: The KARHDIR C7 Walk-Behind Floor Scrubber combines a 22-inch cleaning path with a 31.5-inch squeegee suction width. It scrubs the floor and recovers dirty water as the machine moves forward, helping reduce the number of passes required during routine cleaning.

UP TO 32,000 SQ. FT. PER HOUR: With theoretical cleaning productivity of up to 32,000 square feet per hour, the C7 is designed for medium to large commercial spaces, including warehouses, factories, retail stores, schools, workshops, and other facilities.

LARGE DUAL-TANK SYSTEM: The machine features a 15.9-gallon solution tank for clean water or approved cleaning solution and an 18.5-gallon recovery tank for collected wastewater. Separate tanks help prevent clean solution from mixing with recovered dirty water and reduce interruptions during larger cleaning jobs.

BRUSHLESS MOTOR DESIGN: Brushless motor technology supports stable performance while reducing wear associated with conventional carbon brushes. The design also helps lower routine motor maintenance and operating noise during commercial cleaning.

VERSATILE HARD FLOOR CLEANING: The C7 is suitable for compatible hard surfaces such as concrete, tile, marble, epoxy, PVC, emery, terrazzo, and sealed hardwood. Select the appropriate brush, floor pad, and cleaning solution according to the floor material and soil level.

Features & Applications

One-Pass Scrubbing & Drying

• Clean water or approved low-foaming detergent is delivered from the solution tank to the floor.

• The rotating scrub brush agitates the surface to loosen dirt, marks, and residue.

• The rear squeegee gathers the dirty solution as the machine moves forward.

• The vacuum system transfers recovered wastewater into the separate recovery tank.

• For the best result, pre-sweep loose dust, stones, metal fragments, and larger debris before scrubbing.

Choose the Right Brush or Floor Pad

Different floors and cleaning tasks may require different floor-contact materials.

• Use a compatible scrub brush for textured floors, grout lines, and general cleaning.

• Use an appropriate floor pad and pad driver for polishing, maintenance cleaning, deep scrubbing, or floor stripping.

• Match the brush or pad diameter to the machine specifications.

• Confirm that the selected brush, pad, and detergent are suitable for the floor finish.

• Test the cleaning setup on a small, inconspicuous area before cleaning sensitive surfaces.

Easy Walk-Behind Operation

• The walk-behind design gives the operator direct control of the cleaning path.
• The machine is suitable for cleaning open floor areas, aisles, and spaces with fixed obstacles.
• The wide rear squeegee helps collect water beyond the width of the scrub deck.
• The rotationally molded polyethylene housing is designed to resist corrosion and everyday impact.
• The anti-collision body design helps protect the machine during regular commercial use.

Complete Parts Set

The C7 is supplied as a complete machine package for setup and operation, together with an additional set of consumable parts. Check the package list supplied with the product to confirm all included components before assembly.

Use only brushes, floor pads, squeegee blades, chargers, and replacement parts that match the C7 specifications. Incorrectly sized or incompatible parts may affect cleaning performance or damage the machine.

Care & Maintenance

• Empty and rinse the recovery tank after each use to prevent residue and odors.

• Do not allow dirty water to remain inside the recovery tank during storage.

• Inspect and clean the squeegee blades regularly to maintain effective water pickup.

• Remove hair, fibers, and debris wrapped around the scrub brush or pad driver.

• Check the vacuum hose and water pathways for blockage if the machine leaves excess water behind.

• Clean applicable filters and screens according to the user manual.

• Charge the machine after use following the charger and battery instructions.

• Store the floor scrubber in a clean, dry, and well-ventilated location.

Important Use Notes

• This machine is designed for compatible hard floor cleaning and is not intended to collect large dry debris.

• Pre-sweep the floor before scrubbing to help protect the brush, squeegee blades, and vacuum system.

• Use only low-foaming cleaning solutions approved for automatic floor scrubbers.

• Do not use highly corrosive, flammable, or incompatible chemicals in the solution tank.

• Avoid prolonged water exposure on unsealed wood or other moisture-sensitive flooring.

• Follow the operating, charging, maintenance, and safety instructions in the product manual.

• Actual cleaning productivity depends on operator speed, floor condition, obstacles, cleaning method, and required overlap.
