Hi, I'm gonna try although yours it's an old post! Did the bissell Crosswave work for your non slip tiles? I'm going mad at finding something that works, we had a extension built with porcelain outdoor tiles, they are non slip (R11) so I can't possibly use anything that slides on them just like you. And because the area is actually an extension (indoor)I can't even jet wash them because of the mess, I have all white skirting boards 😵💫😣. I haven't found any other feedback online, and want to make sure I'm not throughing money away, thanks for reading.
