Electric toothbrushes are popular purchases every year in Amazon Prime Day deals, so much so that the website is completely flooded with the stuff. Not only do you have massive amounts of old-guard models from Oral-B, Philips, Colgate and more, but you’ve got newer upstarts like Suri, Ordo and Supermouth to browse, as well as Amazon’s usual range of no-name dupes.

All the while, they all pack different features, be it pressure sensors, multiple modes, AI brush guidance or reward points. It becomes harder to choose between them because of all the noise!
This is where I come in. I’ve reviewed plenty of electric toothbrushes in my time as TechRadar’s resident health technology editor. I’ve put together our best electric toothbrush buying guide, and I’ve picked out a trio of products that a) are all discounted during Prime Day and I think will be good value for money. For comparison purposes, I’ve grouped them into three categories: under $50, under $100, and under $200. Let’s get started!
Under $50: Ordo Sonic Lite
I liked this electric toothbrush when I reviewed it in 2024, calling it ‘simple and light in function, but great value’. Therefore, even though it’s a tiny discount (the Ordo Sonic Lite was $38.47 but is now $34.99 at Amazon), the brush is usually such a good value that I still feel comfortable recommending it.
The USB-C charging port is convenient, the battery life and brushing power are impressive, and it comes in a nice range of colors. The sonic handset (which simply means ‘vibrating’ in this case) has two modes (soft and hard), a two-minute timer and a pulse every 30 seconds to remind you to switch ‘zones’. That’s all most people need out of an electric toothbrush.
Under $100: Suri 2.0 Sustainable Toothbrush
The Suri range of electric toothbrushes are built with quality and sustainability in mind. The reusable heads are made up of bamboo, while the aluminum handle can actually be disassembled so the device can be repaired to reduce electronic waste.
It’s also a very good toothbrush, with a powerful motor, month-long battery life, head cover for travel, an optional case with UV light to kill bacteria, and a pressure sensor that prevents you from pushing too hard on your teeth. Our reviewer awarded it 4.5 stars and claimed it “cleans up on all fronts”. It even comes with a sticky-backed magnet so you can easily mount it to your bathroom wall.
Right now, you can get the Suri 2.0 Sustainable Electric Toothbrush (no case) marked down from $105 to $84 at Amazon, a 20% discount.
Under $200: Philips Soniclean Diamondcare 9000
A powerful premium electric toothbrush, the Philips Sonicare Diamondclean 9000 is packed with features most of us would never think of, with 12 brush settings, a powerful motor that delivers 62,000 bristle movements per minute, smart teeth cleaning, coaching via the Sonicare app, a USB charging travel case and more.
In our review we said it was a “powerful, good-looking electric toothbrush with a wide range of modes and intensity settings so you can tailor it to suit you”. Although we didn’t think it was smart enough for the asking price, you can now get the Philips Sonicare Diamondclean 9000 two-pack for 50% off, marked down from $399.99 to just $199.99 for two brushes, charging cases and stands. At this price I would recommend it if it’s within your budget.
