    I’m really happy with this water flosser! It’s easy to use, has great water pressure, and makes my teeth feel super clean and fresh. It’s especially helpful for cleaning between teeth and along the gumline. Very convenient for daily use. Great quality for the price! Highly recommend!

    great cheap flosser

    Reviewed in the United States on October 11, 2026 · Color: Black | Set name: Professional Set · Verified Purchase

    Transitioning from traditional string to a water stream device completely changes daily oral care. This sleek black unit is incredibly powerful and easily reaches spots that regular brushing misses entirely. The reservoir holds plenty of water to get through a full cleaning session without needing a refill halfway through.

    It is highly effective at blasting away stubborn debris and leaves the entire mouth feeling incredibly fresh. The battery life is absolutely fantastic, holding a solid charge for weeks at a time, which keeps the bathroom counter completely free of messy tangled cords. The multiple pressure settings are a great feature, allowing for a gentle wash around sensitive areas or a stronger pulse for a deeper clean. Anyone looking to seriously upgrade their daily hygiene routine and get that professional clean feeling at home will be extremely satisfied with this device.

    Great customer service and product

    Reviewed in the United States on October 5, 2026 · Color: Sky Grey | Set name: Professional Set · Verified Purchase

    It is my pleasure to offer a five star review of this product. This flosser does a superior job and gives an excellent range of options as to how much pressure you wish to use. It is easy to hold, the water tank holds enough water for a thorough flossing without having to refill. The battery holds a charge for quite some time as advertised, which I put to the test with a two-week trip abroad and did not have to charge once.

    And now for the really good bit. I've had my flosser for two months and it stopped working for no apparent reason. The troubleshooting guide on the website was clear and intuitive. I tried all of the solutions and on the first go round could not get the unit working again. At this point I contacted customer service via e-mail on a Saturday. I received a prompt reply saying they would respond to me first thing Monday morning. In the meantime, I gave a couple of the troubleshooting suggestions a second try and was pleasantly rewarded with a working unit. Meaning I would not have to go through the hassle of packaging and returning. Also saving me the embarrassment of returning a perfectly good unit. I sent them a second email (Sunday night) letting them know the unit was working. When I opened my e-mail on Monday morning at the top of the queue were two emails from customer service the first one with a few more suggestions for troubleshooting and the second one an e-mail responding to my second e-mail letting them know that I had got the unit working. Both emails reflected care and concern in a very professional and pleasant manner. I have been fortunate enough on many occasions to receive great customer service from manufacturers. In this case COLSUS stands out and I'm even happier with my purchase. Thank you!

    GREAT product. New charging cable connector is a change for the worse

    Reviewed in the United States on September 12, 2026 · Color: White | Set name: Professional Set · Verified Purchase

    I bought this very good H2ofloss IPX7 machine about a year ago. It lasted one month longer than its warranty and the battery quit charging. So I bought the higher rated COSLUS C20 for its higher #1 rating and better warranty. I found its lowest setting too powerful for me and its charging cable to have a proprietary connector which means it must be carried and used rather than a normal USB micro cable. Its charging connector cover also is not attached to the machine and therefore easy to lose if dropped. So I bought this H2ofloss IPX7 again. It has more speed levels, now comes with more accessories, and is still much better than the C20 but disappointingly has now changed to a proprietary cable connector as well rather than the original convenient USB micro. Meaning the cable now has to be carried if travelling like the C20. Making it less convenient than the older machine. Dumb change. But still overall the better choice. Please switch back to the generic USB micro.

    Great Water Flosser with Multiple Attachments for a Deep, Refreshing Clean

    Reviewed in the United States on October 15, 2026 · Color: Black | Set name: Professional Set · Verified Purchase

    I really like this black Waterpik-style water flosser and how versatile it is for everyday dental care. The sleek black design looks modern and attractive, and I especially appreciate that it comes with multiple interchangeable attachments for different oral cleaning needs. Having different tips to choose from makes it convenient for cleaning between teeth, along the gumline, and around those harder-to-reach areas that a regular toothbrush might miss. It’s nice having one device that offers several cleaning options rather than needing multiple dental care tools. The water flossing feature is also a great addition to a regular brushing routine, especially for anyone who wants to pay a little extra attention to their teeth and gums.

    Another feature I appreciate is how convenient water flossing can be compared with trying to maneuver traditional dental floss into tight spaces. The stream of water helps rinse away loose food particles and debris from between teeth and around the gums, leaving your mouth feeling cleaner and fresher. I also like having the option to switch attachments depending on what areas I’m focusing on. Whether you’re cleaning around dental work, paying extra attention to your gumline, or simply wanting a more thorough daily cleaning routine, the different attachments add a lot of versatility. There can be a little learning curve when first using a water flosser, especially when figuring out how to position the tip without splashing water everywhere, but it’s something that becomes easier with practice.

    Overall, I think this is a great addition to an everyday oral hygiene routine. The combination of its attractive black design, interchangeable cleaning tips, and convenient water flossing makes it a practical product for anyone wanting to improve their dental care habits. I especially like that it can complement regular brushing and make cleaning those difficult areas a little easier. It’s a useful option for anyone interested in taking better care of their teeth and gums at home, and I’m looking forward to continuing to use it as part of my daily routine!

    Very happy

    Reviewed in the United States on October 17, 2026 · Color: Black | Set name: Professional Set · Verified Purchase

    I recently had a "All-in-4" dental implants and full upper and lower arches. This is the only rinse/flush/irrigation product I'd recommend. This one has a very gentle slow pressure setting for children and elderly, and let me tell it's perfect for flushing out the space between the arch and gums, gentle enough that I'm not concerned about possible injury to my gums from leaving it in a spot too long or cutting because the jet flow is too high. Also like that it's portable, so I can take it on trips . For me this is a must have. I'm very happy

    Great Travel Water Flosser! Definitely Recommend!

    Reviewed in the United States on October 25, 2026 · Color: Black | Set name: Professional Set · Verified Purchase

    Bought this specifically for vacation because I didn't want to give up my regular water flossing routine while traveling. Love that it's cordless, rechargeable, and has a generously sized water tank without being ridiculously bulky. The sleek black design is a bonus, too! It's super convenient to pack and eliminates the hassle of bringing a larger countertop flosser. If you're someone who loves using a water flosser at home and wants that same convenience while traveling, I'd absolutely recommend checking this one out! Such a practical little travel essential!

    Amazing water flosser

    Reviewed in the United States on August 26, 2026 · Color: Black | Set name: Professional Set · Verified Purchase

    Amazing dental floss/toothbrush. If you are a noob like me, you’re gonna get wet just keep a towel handy I’m actually very very impressed. I was not sure what to expect a purchase. This after being frustrated with some dental work I had done my dentist opened up the space between one of my back molars and the tooth in front of it instead of making it easier to floss it just made it easier for food to get jammed in between my teeth, the pressure on this dental floss is amazing and it definitely cleaned not only the problem area, but in between all of my teeth and gums. Only reason I gave this product four stars out of five is previous reviews claiming their toothbrush broke after a month or two of use. If this thing last me six months I’ll come back and change my star rating definitely worth the investment or just to give this type of toothbrush a try for now it will be added to my daily routine. I would have posted a photo, but apparently Amazon wants access to my entire photo library versus just the ones I wanna share.
