Use the regular attachment

Reviewed in the United States on June 14, 2024

Verified Purchase

When I first started using this, I was disappointed. I was using the quad stream attachment (purple tip) and I didn't feel like it worked nearly as well as my Waterpik did. However, after switching attachments, it works great, just like I expected it to. I tried the Philips device because my last Waterpik didn't last as long as I thought it should have. It does have a feature that pauses every thirty seconds but you can switch this off if you find it distracting.

I between devices I tried a handheld water flosser and I found these to be cumbersome and I wasn't able to get in between my teeth like a countertop device. It was like holding a cordless phone up my mouth and made it difficult to use.

like a nice quiet mouth spa.

Reviewed in the United States on December 5, 2023

Verified Purchase

I recently purchased the Philips Sonicare Power Flosser 5000 with high expectations, considering our positive experience with Philips electric toothbrushes. We've been loyal to the brand due to the impressive performance of their dental care products.

Compared to another popular brand we've used, the Waterpik, the Sonicare Power Flosser 5000 lives up to expectations with solid power and a remarkably quiet operation.

The design of this model is both sleek and practical, taking up minimal counter space. One notable feature is the convenient magnetic holder for the handle, making storage easy and fun. Using it is a breeze – just snap the pick in place, fill the tank, and select the cleaning type. The pic control is straightforward and user-friendly.

In summary, the Sonicare Power Flosser 5000 combines efficient performance with a thoughtful design. It's quiet, doesn't monopolize counter space, and the magnetic holder adds a touch of convenience to the overall experience. I wholeheartedly love using it and would highly recommend it to others.

Not as powerful as a water pic, adequate though

Reviewed in the United States on May 8, 2023

Verified Purchase

Not as powerful as a water pic, if you can find a water pic that actually works. After returning two water pics with internal leaks, I decided to get the Phillips machine. It feels sturdier and more refined and, at maximum pressure it works just fine. The magnetic wand holder has to be in the exact right orientation to function properly, but it does look cleaner than the water pic. As for the number of stars, I wouldn't rate the water pic any higher.

Nicely designed, with a wand and hose that stores very neatly and easily. The unit is also much quieter than others I’ve used before.

Broken After Few Months

Reviewed in the United States on May 18, 2024

Verified Purchase

I loved it at first but then after a few months of use, the thing just stopped one day. I noticed that it started leaking a little during usage but it was no major issue. My last time using it, it just loudly popped and the nozzle stopped spraying. After a bit of inspection I found that the entire reservoir contents had been draining onto my countertop. It seems that some internal component completely ruptured and made the whole thing useless. Don’t waste your money. This one isn’t worth it.

After a year and a half

Reviewed in the United States on May 28, 2024

Verified Purchase

A year and a half and it barely works. It sounds like a motor boat with fuel issues. Every once in a while it will surprise me and work for a few seconds. When it worked I loved it but now not so much. Not sure how long I should’ve expected it to last but for the cost I feel it should’ve been longer

Nothing annoys me more than that purchasing something on Amazon Australia to be delivered to an Australian address that comes with a lead for US power so that I now have to find an adaptor to use it.

good pressure, so much so, take care where you point it! the reservoir is a good size, i don't think the all-in-one versions would have enough water. it'd be nice if you could just hook it up to the faucet ... can't comment on longevity, but 4 weeks in, no issues.
