I don't think it is a battery failure but the fine jet getting clogged. I had this with a Panasonic EW DJ40

i bought one 2 years ago but after 2 months the battery failed. The charging piont fills with water and the connections corrode. The water bottle also cracked due to the vaccum crfeated during operation.After reading the other comments I think Waterpik should show some sympathy with customers and recall this model.

I bought one of these a month ago as I have braces, top and bottom. Seen dentist and hygenist since and they are amazed at how clean my mouth is. Recommend use with warm water. I think it's excellent.

Firstly the re-charge point is in line with the water flow when you are using it, which will cause the re-charging to fail eventually. Secondly the water tank is very hard to empty and mine eventually had black mould growing in it. I would not buy this model again but am a ..
