It’s not often that a toothbrush makes it onto but then this isn’t any ordinary toothbrush. Philips’ top-of-the-range electric toothbrush, the Sonicare DiamondClean, promises the ultimate hi-tech tool for keeping your pearlies ultra white, but how does it really scrub up?

With the world on the edge of economic meltdown and a manual toothbrush widely available for a couple of quid, you have ask yourself seriously why you’d want to spend £250 on Philips’ flagship electric toothbrush. However, this feature-packed cleaning machine has a lot of the answers. It not only takes the arm ache out of getting consistently hygienist-clean teeth but it’s also a gadget-lovers dream bathroom weapon.

Philips Sonicare DiamondClean Features
The Sonicare DiamondClean comes in a stylish matte white, is about the height of a pint glass when the heads are attached and has some truly standout features.

Five different brushing modes - Clean, White, Polish, Gum Care, Sensitive - let you customise your brushing to get a really effective regime.

The real cleverness though comes with the USB travel case that doubles as a charger while it protects your brush, thanks to a mini USB slot on the outer edge.

The stylish silver case is robust and, at about twice the size of your average glasses case, is just about acceptable for travelling light. As it is USB charged, you can choose to hook it up to a laptop or plug it into the mains using the USB adaptor plug that comes in the box. Sadly Philips opted for mini USB over micro which really feels like a trick missed here.

When you’re not on the move, there’s also a clever inductive charging glass that plugs into a shaver point and is about as stylish as you’ll get for a vessel for your toothbrush.

While brushing, there's a handy timer with intermittent ‘quadpacer’ beeps at 30 second intervals to encourage even cleaning and protect against over scrubbing.

Philips Sonicare DiamondClean Build and Design
Aside from the minimal, classic white design, the brush body features a single power button on the handle on the front, a column of mode lights that show up once turned on and a battery status indicator that flashes orange when you need to power up.

It comes with two interchangeable brush heads that are simple to add and remove. The smaller head sports diamond shaped bristles that promise – and deliver - gentle and efficient cleaning.

Philips Sonicare DiamondClean Performance
The Sonicare DiamondClean is a comfortable weight and easy to hold, with the angled bush neck making it super simple to get to those tricky back gnashers.

Philips has employed rapid vibration rather than the sliding brush technique we see with other brushes and kicks out a massive 31,000 brush strokes per minute – unmatchable with the human arm.

While the size of the head and the vibrating motion isn’t immediately natural for those used to brushing with a larger manual brush, it doesn’t take long to feel comfortable guiding the head for an effective clean.

The option of five different brushing modes is excellent, giving you complete control over your own regime and the addition of a ‘sensitive’ setting is great if you prefer a softer clean.

One word of warning however, when starting up the brush and switching between modes, it’s best to have the brush in your mouth to avoid splattering toothpaste all over the bathroom.

The 2-minute timer is also a welcome addition but the fact that the brush switches off after the allotted time is a bit irritating. We often found we needed slightly longer to allow for interruptions and having to switch it back on does seems a little counter intuitive.

The DiamondClean’s battery life is impressive. In testing we got just shy of a month’s use from it without needing to recharge but we would have liked a demarcated battery indicator to give us earlier warning when we’re running low, rather than the jump from green to orange.

Philips Sonicare DiamondClean Verdict
Philips claim the DiamondClean will give you a brighter smile in just one week and while this is pretty tough to discern, we can say that after a single use our teeth felt noticeably cleaner than with a manual or our usual electric toothbrush.

The multiple modes certainly encouraged a more varied cleaning regime and the brushing pacer was really effective at stopping us over brushing or spending too long on one area.

The travel case is a fantastic addition but we would have liked to see micro rather than mini USB charging but with a battery life that’s longer than most travel breaks, this is less of an issue.

Overall the DiamondClean is a great electric toothbrush and while there are cheaper alternatives with the potential to produce similar results, if you’re after best in class form, function and some pure gadget indulgence then the £250 price tag is a lot easier to swallow. It should at least mean one or two fewer trips to the hygienist.
