Solimo sonic rechargeable toothbrush

Our verdict

There is no reason to buy one now, and you are unlikely to find one. If you own one, the practical question is replacement heads. Once you cannot find heads that are clearly listed as fitting your exact brush, replacing the whole brush with a basic Oral-B or Philips model is cheaper and simpler than experimenting with unbranded heads.

Which product this is

The 2021 Aligners.co review photographed the box and brush. The box reads "Solimo Sonic Rechargeable Toothbrush" and claims "up to 5x better plaque removal than a manual toothbrush" with "Advanced Sonic technology, 31,000 movements per minute". The brush has a slim, conventional-shaped head, not a round Oral-B style head. The plaque claim is Amazon's own, and we have not seen the study behind it.

That is the extent of what we can confirm about the UK model. We could not find a current or archived UK product listing, manual or model number for it, so we cannot verify its timer, battery life, charging time or head fitting. Our 2021 review said it came with a spare head and a charger with a two-pin shaver plug, had no timer, and needed 16 hours to charge, but the same review wrongly described it as an oscillating brush that took Oral-B heads, so treat those details with caution.

Is it still sold?

No Solimo or Amazon-branded sonic toothbrush appeared when we searched Amazon UK on 29 October 2026. In the US, Amazon has sold a Solimo Pro Advanced sonic brush, and now an Amazon Basics sonic brush described as previously Solimo. The US Solimo Pro Advanced listing claims up to 7 times better plaque removal, not the 5 times on the UK box, so they are not the same product. Do not rely on US listings for your brush's features, charger or heads, and do not use a US charger with it.

If you own one

Check what it does. Brush for two minutes and note whether it pauses or changes rhythm every 30 seconds. If it does not, it has no quadrant timer, and a phone timer will do the same job. Look on the base of the handle and the charger for a model number and voltage, which you will need if you search for parts.

Heads. Brush makers advise a new head every 3 months, or sooner if the bristles splay. Oral-B heads will not fit, because this is not an oscillating brush. Some unbranded sonic heads look similar, but a head that is not made for your exact handle may fit loosely, vibrate differently or come off.

Only buy heads whose listing names the Solimo sonic brush you have; if you cannot find any, it is time for a new brush.

Charging and battery. Use only the charger that came with it, and keep it away from water. The battery is built in. If it no longer lasts a few days on a full charge, replace the brush rather than buying a non-matching charger.

Disposal. Electric toothbrushes contain batteries, so take an old one to a small electricals or battery recycling point rather than putting it in household waste.

What to replace it with

Prices are sale prices on the date shown and change often. Our Oral-B Vitality Plus review explains what the most basic Oral-B models leave out.

Both types of brush have trial evidence behind them, though the trials compared types of brush rather than these models. A 2026 analysis of 19 trials found both oscillating-rotating and sonic brushes reduced plaque and gum inflammation more than manual brushes, with oscillating-rotating ranked first. The NHS says a manual brush is just as good if you clean every surface properly.

During aligner treatment

Any working brush, electric or manual, is enough to clean your teeth before your aligners go back in. If your Solimo's battery is failing, a manual brush will do the job until you replace it. Clean your trays separately as described in our guide to cleaning aligners.

How this review was put together

This review first appeared on Aligners.co in February 2021, and the photo is from that review. The original review described the Solimo as an oscillating brush compatible with Oral-B heads; the box in its own photo shows a sonic brush, and that error was corrected in October 2026. This update is based on the box text in that photo, Amazon UK and US listings and published research, checked on 28 and 29 October 2026. We did not retest the brush.
