Upgrade your daily routine with the Amumu EB511 Sonic Electric Toothbrush - one handle, five brushing modes, six brush heads, and up to 40 days of cordless use on a single charge. FIVE MODES, ONE BRUSH Clean (the 2-minute default deep clean), White (surface stain care in 2 minutes), Polish (gentle polishing for the front teeth - press and hold the power button to stop early), Milder (a gum-massage routine recommended for first-time electric toothbrush users), and Soft (extra gentle for sensitive teeth and gums). The motor drives up to 19,800 sonic vibrations per minute across all five modes. Short-press the power button to turn the brush on or off; short-press the mode button to switch modes while brushing. SIX BRUSH HEADS INCLUDED Six replaceable brush heads come in the box - at the recommended 3-month replacement interval, that is roughly 18 months of refills covered. No separate refill purchase for the next year and a half, and every household member can keep their own head on the same handle. SMART TIMING, DENTIST-RECOMMENDED The brush runs for the dentist-recommended 2 minutes and pulses every 30 seconds, nudging you to move to the next quadrant. No guessing, no under-brushing. IPX7 WATERPROOF The sealed IPX7 body handles rinsing under the tap after every use. Close the dust cover at the base before charging and keep the charging port dry. TYPE-C DIRECT CHARGE Skip the charging dock. Plug the included 80 cm USB-C cable into any standard 5V 1A adapter, power bank, or laptop - straight into the base of the handle, and the 500 mAh lithium-ion battery reaches a full charge in about 3 hours - good for up to 40 days of typical brushing (2 minutes, twice a day). A practical pick for travel, dorms, and busy households. QUIET AND LIGHTWEIGHT At under 55 dB the motor stays quiet enough for early mornings and shared bathrooms - noticeably quieter than most sonic brushes in this class. The handle weighs just 88 g and stands 191 mm tall, slim enough for a toiletry bag or a crowded toothbrush cup. WHAT'S IN THE BOX 1 x Amumu EB511 sonic toothbrush handle (White), 6 x replaceable brush heads, 1 x 80 cm Type-C charging cable, English instruction manual, retail box. COMPLIANCE AND CARE Product: CE-EMC, CE-RED, CE-RoHS, BSCI. Battery (14500 Li-ion 500 mAh): UN38.3, MSDS, sea-freight classification. Replace each brush head every 3 months, or sooner if bristles are visibly frayed. Rinse and air-dry the head after each use; do not pull the bristles. GOOD TO KNOW Recommended for adults and teens. Keep out of reach of children - this is not a toy. If you have a pacemaker or other implanted device, or have had oral surgery in the last 2 months, consult your doctor or dentist before use. Mild gum tingling during the first 1-2 weeks is common and usually settles; if it persists beyond 2 weeks, stop use and consult a dentist. AMUMU SUPPORT Questions about setup, modes, or replacement heads reach the Amumu support team through Walmart messaging; we reply within one business day. Covered by a 12-month limited warranty.
