Our kitchen floor is stone tiles with a deep grout which has lots of lumps and bumps on it and nothing cleans it properly except a scrubbing brush with me on my hands and knees which is time consuming and back ache inducing to do multiple times a week and I'm lazy
We tried this one but the bumps in the floor just tore the sponge on first use
. Then we had this one which the spray nozzle limescaled up within a month. There must be something decent out there - any recommendations?
