Kärcher Tilt Safety / Orientation Sensor Sensitivity

Cordless vacuum stops when tilted to certain angles (e.g., when cleaning high areas)

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Over‑sensitive tilt sensor, Loose sensor mounting, Wiring issue to sensor, Firmware threshold too low

Safety first: Remove the battery before opening the housing.

Confirm behavior: Note the angles at which the vacuum stops. Ensure it is not simply a low‑battery cut‑out.
Reset unit: Remove the battery for 1 minute, then reinstall and test again.
Service if persistent: Tilt sensor calibration is not user‑adjustable on most Kärcher models. If the vacuum consistently cuts out at normal working angles, the sensor or PCB likely needs replacement.
