Electric toothbrush

I am in the market for an electric toothbrush and have chosen a rotating toothbrush with brushing modes as my desired model. Of the available brands, I prefer the Oral-B electric toothbrush. I am looking for an electric toothbrush with a long-lasting battery and multiple brushing modes so that I can easily customize my brushing experience. Furthermore, I would like to find an electric toothbrush that is within my budget. To be specifically I want to design it for interdental cleaning. Hence, it should be small in size as much as possible and it’s working in clock and anti clock wise direction with slow rpm.
Thanks
