The reason bathroom grout stays grimy is that scrubbing it by hand is slow and hard on your wrists. This is a cordless powered brush that spins the head for you: one button starts it, you guide it along the surface, and it works through soap scum, limescale marks, and tile grout without you having to lean into it.
Five interchangeable heads cover the range of surfaces in a bathroom and a kitchen. The stiff nylon brush handles tile, grout, and shower trays; the sponge head suits baths, sinks, and glass where a bristle would scratch; the soft cashmere-style head is for polishing taps and finished surfaces. Heads pull off and push on without a tool, so you can switch part-way through a job.
It charges over USB and runs cordless, which matters in a shower cubicle where there is no socket and you would not want a mains cable near water anyway. The body is ABS with nylon bristles, and the kit includes a hook and an adhesive pad so it stores on a wall instead of disappearing into the back of a cupboard. It works as well on kitchen tiles, toilets, worktops, and car interiors as it does on a bathroom, which is usually what justifies buying one at all.
