The tank is more of a bother than help
I have a few other similar items. The difference (besides one having a camera) is the size and way that the water is handled. The one with the camera has a built-in tank that holds about 150ml (about 5 oz) and it also has a camera that records and a UVA disinfector https://www.amazon.com/gp/product/B09KLM695X . I loved this in the beginning, and still think it's a damn good flosser, but I don't really find much use at all for the camera. The UVA disinfector is a great idea but, in the end, the 150 ml tank is not enough and I have to re-fill it mid-flossing.<br /><br />The other irrigator https://www.amazon.com/gp/product/B09L1FK5XC , was a bit of a disappointment to me because you had to dip a hose into a water glass as it did not have its own internal tank. It did a great job, pretty much as good as the other, but I liked the all-in-one style of the other irrigator.<br /><br />And so this unit looked good since I could use the tank or not, and the tank is large enough for a whole water flossing session without filling. Cool. Except that with the water tank attached, this is very unwieldy and not at all fun to use. So, remove the tank and now we're back to using a water glass that I can fill with as much water as I like.<br /><br />This, as with the others, does a very good job of cleaning and is easy to use with long battery life. It all comes down to the water tank (and whether or not you want the other stuff such as a camera and UVA light). After trying several of these I have come to the conclusion that, although it does not look as cool, anywhere you can floss your teeth you can find a water glass (or fill the sink with water) and you won't need to worry about refilling, running out of water, or being uncomfortable to hold. This unit is good but I already threw out the water tank.<br /><br />Review of: CITAITAI Water Flosser Cordless, Portable Water Flosser IPX7
