Say goodbye to dirty hands and germs with an innovative, hands-free automatic touchless soap dispenser that was designed for everyday use. Introducing Otto Automatic Hand Soap Dispenser from Umbra Updated Design!! Otto Automatic Hand Soap Dispenser is now available with a larger 8.5oz (255ml) capacity for even more cleaning and less refilling. Otto’s sleek profile, high-gloss finish, and chrome accents look great in any kitchen or bathroom. The innovative sensor pump technology automatically dispenses a fixed amount of liquid soap – not too much, not too little - helping reduce waste and saving you money on supply costs. Otto’s new 8.5oz (255ml) capacity can be filled with dish soap, liquid hand soap, or hand sanitizer. The fluid level indicator window lets you see when it’s time to refill and the large, top-load refill opening makes topping it up quick and easy. Operating on four AAA batteries (not included), Otto measures 3.5 x 4.5 x 10 inches (8.89 x 10.16 x 25.4 cm). IMPORTANT INFORMATION: After inserting the batteries, if the blue light comes on and you hear the motor but the soap doesn’t dispense, try pouring the soap into a separate container, then fill the pump with hot water (not boiling) and let sit for 5-10 minutes until cool. Put your hand in front of the motion sensor and repeat until the water starts to flow well. Now empty the water and refill the pump with soap. If you find the brand of soap you have purchased is too thick, try adding some water to thin it out. Otto Automatic Soap Pump is not recommended for use with foaming hand soaps. Stop messing around with germ covered hand soap dispensers and order Otto from Umbra today.
