This Beldray Deep Clean Power Scrubber Brush is designed for deep cleaning, allowing you to scrub away stubborn dirt and grease from tiles, hobs, window seals, upholstery, and more. It comes with 4 interchangeable oscillating brush heads for precise cleaning and features a non-slip grip for easier control. This handheld tool is ideal for grout, tiles, shoes, and even refreshing pet bowls. It requires 4 x AA batteries to operate (batteries not included). Please ensure batteries are inserted with the correct polarity and the compartment is secure. Do not push too hard on the surface being cleaned as this may stop the head from spinning. Ensure the selected head is attached correctly by slotting it on and turning clockwise to secure.
