Product information and benefits

Efficient, economical, user-friendly: the HDS 7/12-4 M from Kärcher is a single-phase, heated, entry-level high-pressure cleaner in the Middle class. The hot water high-pressure cleaner is fitted with a 4-pole electric motor and offers not only extensive equipment but an ideal balance between outstanding cleaning results and maximum environmental protection. This is ensured on the one hand by the patented nozzle technology, ceramic pistons, turbo blower and increased pump efficiency, and on the other by the unique eco!efficiency mode, precise cleaning agent dosing unit and optimised burner engineering. The machine also offers maximum user-friendliness for you as the operator: the intuitive control panel, LED displays and sophisticated mobility concept simplify operation, handling and transport of the machine. And you will not have to make any compromises when it comes to servicing and maintenance, as all of the components required for maintenance are easily accessible, and operating data can be retrieved at any time using the service switch.

Economic efficiency

In eco!efficiency mode, the machine operates in the most economical temperature range (60 °C) – with full water flow. The burner cycles are optimised to reduce fuel consumption by 20% compared to full load operation.

Maximum efficiency

Proven and highly efficient burner technology. 4-pole, slow-running electric motor guarantees a long working time.

Operational safety

The large, integrated water fine filter reliably protects the high-pressure pump against small dirt particles. The integrated exhaust gas thermostat switches off the drive motor if the emission temperature exceeds 300 °C. The Soft Damping System (SDS) compensates for vibrations and pressure peaks in the high-pressure system.

Storage

Safe and ample storage options for protective equipment, accessories and detergents. Storage hooks for power cable and high-pressure hose.

Mobility concept

"Jogger" design with large rubber wheels and steering roller. Integrated tipping trough for effortless transport over ledges.

Save time and energy: EASY!Force high-pressure gun and EASY!Lock quick-release fasteners

Fatigue-free work at last: the EASY!Force high pressure gun. EASY!Lock quick-release couplings: durable and robust. And five times faster than screws.
