Yesterday I tried out the suction ring for tile. It has small holes all around the perimeter to slurp up water n slops. On VCT, I scrubbed with the blue tile brush (slow but effective). The ring picked up most of the water, but I expected it to draw a lot more aggressively and leave the floor nearly dry. What has been your experience? Is the new tile brush with suction slots better than the brush & ring combo? Would enlarging the suction holes in the ring make it work better?
