Included productivity & control features explained
KIK Key System: Kärcher Intelligent Key (KIK) provides secure machine access, allowing administrators to assign user permissions, restrict operating functions and customise cleaning parameters for different operators. This helps prevent unauthorised use, reduces training requirements and ensures consistent cleaning performance.
Machine Connect: Integrated smartphone connectivity enables operators and fleet managers to monitor machine status, customise settings, manage user permissions, access maintenance information and troubleshoot faults, helping to maximise uptime and simplify fleet management.
DOSE Cleaning Detergent Dosing: Automatically dispenses the correct amount of cleaning detergent according to the selected concentration, reducing chemical consumption, lowering operating costs and delivering consistent cleaning performance every time.
Auto-Rinse Tank Rinsing: Automatically rinses the dirty water tank after use, improving hygiene, reducing unpleasant odours and helping to minimise operator contact with contaminated wastewater while significantly reducing machine cleaning time.
Auto Fill Fresh Water Filling: Automatically fills the clean water tank directly from a mains water supply, allowing unattended filling while preventing overflows with automatic shut-off. This saves operator time, improves productivity and ensures the machine is ready for use with minimal intervention.
Linatex® Suction Blades: The 850mm parabolic suction bar is fitted with premium Linatex® natural rubber blades, offering exceptional abrasion resistance, flexibility and chemical resistance. This provides excellent water recovery, leaves floors drier after cleaning and delivers a longer service life than conventional rubber blades, helping to reduce maintenance costs.
