Is the Soniclean Pro 3500 worth it?

At $17.99 at eBay as of November 6, 2026, with 8 heads included, it is a cheap way to get a sonic brush and a long refill supply. Check that you are fine buying Soniclean heads, since Sonicare heads do not fit.

Does it take Sonicare brush heads?

No. The Pro 3500 is listed as not compatible with Sonicare brush heads. Use Soniclean replacement heads.

How often do I replace the heads?

Dentists generally suggest a new head every 3 months, so 8 heads last about two years. Soft bristles wear faster if you press hard.

Can I use it in the shower?

The handle is waterproof, so splashes and shower use are fine. There is no cover for the head, so dry it before packing it.

How does it compare with a Sonicare?

It matches the 40,000 vibrations per minute of many Sonicare models and costs far less, but it lacks Sonicare's head ecosystem and any timer or pressure sensor features.

The handle and 8 replacement brush heads in manufacturer packaging. No travel case or head cover is included.

Our take on the Soniclean Pro 3500 Sonic Toothbrush with 8 Heads

The Soniclean Pro 3500 is a rechargeable sonic toothbrush that runs at 40,000 vibrations per minute and ships with 8 replacement heads. It has a waterproof handle, soft bristles and is aimed at people with sensitive gums who want plaque removal and whitening. Its best new price is $17.99 at eBay as of November 6, 2026, and it is the only new price listed, so there is no recent range to compare against. The bundle of 8 heads is the main draw at this price.
