I have been using this product for 1.5 years now(I purchased it on September 2015th). It’s my favorite Waterpik so far. I love it for its huge water tank and high pressure. I also love the Sonic Toothbrush that comes with this product. Overall I absolutely recommend it for your home.

It’s my personal experience

I’m not a medical expert by any means. It’s just my experience from using this product over a long period of time. Now let’s dive into the review.

Waterpik Complete Care Water Flosser and Sonic Toothbrush, WP-900

The water tank is huge and I don’t need to refill it

The capacity of the water tank is 23 oz (700 ml). I love it because I fill it with water once and it is enough for me to clean my entire mouth. I know that other portable water flossers have small water tanks and you have to refill them several times to clean your entire mouth.

I also have braces and I need to clean them very well. And this Waterpik works great for my braces as well.

The water pressure is good

It provides good water pressure and cleans well. If I got hard food pieces in my braces(like nuts) it removes them as well. So it works for me.

It has 10 settings and you can adjust them to your preference. I personally use the highest one, but I recommend you starting with the low setting. Your gums are sensitive at the beginning and they have to get used to the water pressure. Once you feel comfortable you can gradually increase the water pressure.

The Sonic Toothbrush is high quality

I love the Toothbrush. It is very powerful. It makes my breath a lot better. It works from the internal battery. I have been using it for 1.5 years and didn’t notice any power decrease. Maybe it decreased, but not significantly, so it still works just fine for me.

The Toothbrush comes with 2 heads, which is nice. I replaced my first head after 6 months I guess. I know that it’s advised to change heads more often, but mine was in a great shape, so I kept using it.

It has 2 settings. You just press the button and it starts working. I find the first setting too weak, so I always use the second setting, which is powerful.

I also like 2-Minute Timer. It helps me to clean my mouth more evenly. It makes pauses every 30 seconds, so I know when to move to the next quadrant of my mouth. Very comfortable brushing so far.

It also comes with a plastic travel case. But the toothbrush itself is high quality and I never used the travel case.

The Water Flosser has many tips for any occasion

I have braces so I was particularly interested in the Orthodontic tip. It has a little brush on the end and cleans braces well. I also use generic tip – Classic Jet Tip.

The Water Flosser comes with 5 tips:

  • two Classic Jet Tips – works nicely for general use
  • one Orthodontic Tip – great for braces
  • one Plaque Seeker Tip – for implants, crowns or bridges
  • one Pik Pocket Tip – for furcations and periodontal pockets

This product also has a special Tips Storage where I keep all my tips, which is handy. It is covered with a lid so dust can’t get in there.

Overall feeling is that it’s a quality product

The product is made with good plastic. I’ve been using it for a long time and it still works well.

The weight is 2.4 Lbs, so it stays confidently on my countertop and doesn’t shift around. The dimensions are 7.7″ x 5″ x 10.6″.

The fact that it also saves my countertop space by combining 2 products into 1 is also a plus.


Waterpik Complete Care is a high-quality product. The Water Flosser provides high pressure. The Sonic Toothbrush is powerful as well. I’ve been using it for several years and it still works for me. So I absolutely recommend it.
