Listings describe either rotating (spin) or oscillating-rotating motions; many product descriptions use 'rotating' or 'oscillating rotating' to describe the brush-head action.
Many spin toothbrushes offer multiple modes—commonly three—such as gentle/sensitive, daily/regular, and a deeper or massage cleaning mode.
Some rechargeable models list runtimes up to 30 days per full charge. Other models use replaceable batteries (for example, a single AA), but available product details do not specify runtime for replaceable batteries.
Some listings include a 2-minute timer with 30-second interval alerts or pulses to cue when to switch mouth quadrants.
Some listings claim multi-fold plaque reduction versus a manual brush (examples quoted in listings include 'Remove up to 11x more plaque from between teeth', 'Removes up to 300% more plaque', and '200% more plaque removal'), and several listings reference whitening or stain-polishing effects.
