Two-part stone roller set from Kärcher for the deep yet gentle cleaning of resistant hard floors made of stone or ceramic. Thanks to integrated bristles, the stone rollers also remove stubborn dirt even on structured floors and from joints. For use with our hard floor cleaner BR 30/1, but do not use on sensitive natural stone floors such as marble or terracotta. The stone rollers can also be easily washed in the washing machine at up to 60 °C.
