Karcher FRV 30 hard surface cleaner is designed for use with a Karcher pressure washer and with integrated suction of waste water from the cleaned surface the FRV 30 leaves surfaces much drier than all other hard surface cleaners. Please note: this FRV 30 Hard Surface Cleaner is compatible with pre-2017 Karcher Professional Pressure Washers, which use a black trigger gun. Walls and hard floors can be easily cleaned with the Karcher FRV 30 without splashing water, and without leaving excess water on the ground. Three non-marking wheels give the hard surface cleaner great manoeuvrability, and the integrated handle enables comfortable wall cleaning. The Karcher FRV 30 hard surface cleaner is ideal for many outdoor and indoor applications. The FRV 30 is compatible with the HD and HDS range of professional pressure washers.
