Powerful Cleaning Performance

The machine's high-pressure output ensures faster cleaning times and increased productivity, even in challenging environments.

Trailer-Mounted Mobility for Maximum Flexibility

Built on Kärcher's integrated trailer platform, the HD 9/23 De Tr1 can be transported easily between job sites.

Ergonomic EASY!Force Trigger Gun

The machine comes equipped with Kärcher's innovative EASY!Force Advanced trigger gun, which uses the recoil force of the high-pressure jet to reduce operator fatigue. This ergonomic design significantly improves user comfort during extended cleaning sessions and helps increase productivity on large-scale cleaning projects.
