Kärcher K5 WCM Flex eco!Booster Car & Home Pressure Washer with 145 Bar and Dual Kit

Water-Cooled Motor Built for Frequent Use:

The K5 WCM Flex eco!Booster runs on a 2,100W water-cooled induction motor that operates at a lower temperature than air-cooled alternatives, extending the lifespan of the unit under regular use. It delivers a maximum pressure of 145 bar and a flow rate of 500 L/h, making it well suited to moderate to heavy dirt on paths, patios, decking, fencing, and vehicles.

eco!Booster Lance for Delicate Surfaces:

The included eco!Booster lance delivers 50% increased cleaning performance compared with the standard Kärcher flat jet, while using less water and energy. It is particularly suited to surfaces such as rendered walls, painted wood, and garden furniture where a more focused jet could cause damage.

Complete Car and Home Kits Included:

The Car & Home bundle contains two dedicated kits covering outdoor surface cleaning and vehicle washing. The home kit includes a T 5 surface cleaner, Stone and Façade Cleaner 3-in-1 1 L, and Dirt Blaster lance. The car kit adds a 0.3-litre foam jet, rotating wash brush, and Natural Car Shampoo, so both tasks can be tackled without purchasing accessories separately.

Quick Connect System and 10m PremiumFlex Hose:

All attachments connect and disconnect via the Quick Connect system, which requires no tools and allows lances and accessories to be swapped in seconds. The 10m PremiumFlex high-pressure hose provides generous reach around larger vehicles and outdoor areas, while the 5m power cable adds further flexibility in positioning.

Setup and Care

Getting Started:

Connect the garden hose adapter to your outdoor tap and attach the PremiumFlex hose to the machine using the Quick Connect fitting. Run water through the unit for a few seconds before switching on to prime the pump and clear any air from the line.

Choosing the Right Lance:

Use the eco!Booster lance on painted surfaces, rendered walls, garden furniture, and vehicle bodywork where a gentler, wider jet is appropriate. Switch to the Dirt Blaster for concentrated cleaning of grout lines, stubborn stains, and heavily soiled concrete or stone.

Using the Foam Jet:

Fill the 0.3-litre foam jet bottle with diluted car shampoo and attach it to the G 180 Q gun. Apply foam across the vehicle from the bottom up, allow it to dwell for one to two minutes, then rinse from the top down with the standard lance.

After Use and Storage:

Run the machine briefly on plain water after using detergent to flush the suction hose and internal pathways. Wind the PremiumFlex hose loosely around the onboard storage points and store the unit upright in a frost-free location during winter months.
