9-IN-1 SCRUBBING BRUSH SET: Comes with 9 interchangeable heads so one tool works as a grout cleaner, cleaning brush and all-purpose scrubbing brush for tile, tub, dish, sink, wall, kitchen and other everyday household surfaces around the home. DUAL-SPEED POWER: Switch between a 370rpm fast setting and a 320rpm slow setting so this cleaning brush handles both delicate finishes like glass and tile grout, and stubborn built-up grime, without needing extra manual scrubbing effort. THREE LENGTHS, ONE POLE: The stainless steel telescopic pole adjusts from a 30cm handheld grip to a 130cm full-reach floor scrubbing brush and electric scrubber, so you can clean floors and ceilings without kneeling or stretching. BUILT FOR BATHROOMS: An IPX5 waterproof housing and auto shut-off let it double as a shower cleaner, grout brush and bathroom cleaning brush, rinsing clean and switching off safely if pressure is lost during wet use. ALL-DAY CORDLESS USE: An 18650 1500mAh battery charges via USB-C in 3-4 hours and runs 60-80 minutes, so this spin scrubber and electric cleaning brush is ready for a full cleaning session whenever needed.
