Review on 🚿 Umbra Flex Squeegee - White, Rust-Proof Squeegee with Extended Handle, Suction Cup | Keep Shower Tiles and Walls Dry | Store in Shower | 10¼ x 11½ x 1½ inches by Heather Powell

I've only found two Sliding Shower Scrubbers and this is the best of the two. Better Living's shower mop uses a softer material that may work better, but it also requires the perfect amount to extend past the metal support bar. The Umbra Mop material is stiffer and does not require a metal backing for support, but is also slightly less capable of removing 100% water from the shower glass. I've used both scrapers, but I like the umbra better.
