The Xiaomi Mijia F300 Portable Electric Oral Irrigator is the most advanced water flosser Xiaomi has brought to the F-series — combining the innovative Umbrella Pulse Technology that delivers 7 times the cleaning power of conventional water flossers, 2000 high-frequency pulses per minute, a 240mL large-capacity water tank and 115 days of battery life in a compact, travel-ready design that is fully IPX7 waterproof. The Umbrella Pulse Technology is the engineering breakthrough that distinguishes the F300 from conventional water flossers — rather than projecting a single cylindrical water column that impacts the same narrow contact point repeatedly, the Umbrella Pulse system produces a dual-layer water structure where a focused inner water column is surrounded by an outer ring of fine water mist that fans outward in an umbrella shape. This diffusion double-layer flow simultaneously cleans within the interdental gap with the focused column and cleans the outer surfaces of the adjacent teeth and the gum pocket with the surrounding mist — 

covering a significantly wider cleaning area per pulse than a single jet achieves, which is the mechanism behind the 7x cleaning power advantage. The 2000 pulses per minute frequency means the water pressure contacts the gum line and interdental spaces 33 times per second — at a rate fast enough to dislodge and flush biofilm and food debris from areas that a toothbrush cannot physically reach, including under orthodontic wires, around implant bases, behind wisdom teeth and within the subgingival space where gum disease begins.

Four cleaning modes let you customise each session to your gum sensitivity, oral health goals and the specific area you are cleaning — Gentle mode is designed for first-time water flosser users and anyone with sensitive or inflamed gums who needs the lowest water pressure for comfortable introduction; Standard mode provides the daily routine cleaning pressure that removes food debris and surface biofilm with the efficiency needed for maintaining oral hygiene between dental visits; Strong mode delivers the maximum pressure for deep cleaning around orthodontic appliances, implants and areas with heavy debris accumulation; and Massage mode alternates the water pressure in a pulsing rhythm that stimulates blood circulation 

in the gum tissue, improving gum health over time through gentle periodontic massage therapy. The three included nozzles are purpose-designed for different oral care needs — the Standard nozzle for general full-mouth cleaning, the Multi-Effect nozzle for reaching difficult posterior angles and the Orthodontic nozzle with filaments that thread between bracket and wire for cleaning around braces without the risk of damage. The 240mL water tank provides enough capacity for a complete full-mouth clean in a single fill without needing to stop mid-session to refill.

The integrated smart chip monitors operating conditions in real time to maintain stable, consistent water pressure throughout each session — preventing the sudden pressure surges that unregulated irrigators can deliver and that can traumatise sensitive gum tissue, ensuring every pulse is delivered at the intended pressure for the selected mode. The 2-minute auto power-off prevents the motor from running dry and overheating if the water tank empties mid-session, protecting the pump from heat damage automatically without requiring manual intervention. 

The 115-day battery life from a single USB charge eliminates the charging anxiety associated with shorter-battery devices — at twice-daily use of two minutes per session, the F300 charges less often than once a month, making it genuinely maintenance-free for daily life. IPX7 waterproof rating allows the F300 to be used in the shower and rinsed under running water without any protection — and the fully integrated design with no seams or gaps allows the interior of the device to be cleaned by running water through it at idle, preventing bacterial growth within the water path.
