Grout lines are the nemesis of every homeowner. They start white and clean, and within months they're grey, stained, and almost impossible to restore with a standard brush. The problem isn't effort — it's geometry. A manual brush can't maintain consistent pressure across dozens of millimetre-wide lines.
The Twinbrush 18V's counter-rotating heads are precisely sized to align with standard grout joints. As they rotate in opposite directions, they pull grime out rather than pushing it aside — the mechanical action that makes the real difference on deeply ingrained stains.
From bathroom tiles to large-format kitchen floors, the result is a surface that looks professionally steam-cleaned — without the cost or the wait.
The right tool for every detail.
Soft Brush
Safe on delicate glazed tiles, polished marble, and sensitive finishes. Cleans without scratching.
Medium Brush
The everyday workhorse. Perfect for standard ceramic bathroom and kitchen tiles.
Hard Brush
For heavily soiled grout lines, unglazed stone floors, and areas with deep-set staining.
Adjustable Angle
Tilt the head from -15° to +90° to match floor and wall tiles without changing your posture.
My bathroom tiles look brand new. I've tried everything — nothing worked like this.
