Best Electric ToothbrushesUnited Kingdom - 2026

The Oral-B iO Series 6 earns our runner-up position for shoppers who appreciate real-time digital coaching and interactive screen feedback. Its round brush head delivers a classic mechanical clean, and the multi-color smart pressure ring is a helpful visual guide for protecting sensitive gums.

Where it falls behind Miroooo Brush X is everyday ergonomics and ongoing cost. The 14-day battery life requires frequent recharges on a proprietary 2-pin bathroom plug, the motor runs noticeably loud (>65dB), the plastic handle is heavy (140g), and the high recurring cost of iO replacement heads (£8–£12 per head) makes ownership over two years considerably more expensive.

Philips Sonicare DiamondClean 9000 is well known for its luxury bathroom presentation and iconic charging glass. Its sleek finish and smart brush sync tracking offer an attractive high-end feel for countertops.

However, the value equation is difficult to justify for most UK buyers. The £124.99 purchase price is steep, the charging glass requires an awkward 2-pin bathroom socket, the handle is heavy (135g), and the 14-day battery life feels dated compared to modern 60-day magnetic USB-C docks. If luxury countertop aesthetics are your sole priority, it's a solid performer—otherwise, Miroooo Brush X offers superior lightweight comfort, battery life, and long-term value.

The SURI Pro 2.0 continues SURI's eco-conscious mission with recyclable cornstarch heads, castor-oil bristles, a modular aluminium chassis, and an integrated Touchsense™ pressure sensor, selling as a standalone brush for £85.

While its sustainability focus is commendable, everyday ownership reveals persistent trade-offs. The £85 base box includes zero extra heads or travel accessories, the plant-based cornstarch heads are prone to micro-cracking and loosening under moisture, and proprietary refill packs remain expensive (£14.99 for 3). Without companion app coaching, only 2 cleaning modes, a heavier 85g handle, and a standard 30-day return policy, SURI Pro 2.0 remains a high-priced eco alternative that trails Miroooo Brush X in performance, bundle value, and long-term convenience.

The Oral-B iO3 Matt Black serves as an accessible £75 entry point (RRP £160) to Oral-B's magnetic micro-vibration system. Featuring the classic round brush head, a 360-degree smart pressure ring that glows green for optimal brushing and red for excess force, 3 cleaning modes, and a hard travel case, it delivers a capable mechanical clean.

However, in stripping down the brush to hit an entry price tier, Oral-B removed the defining smart features of the iO line. The iO3 has no interactive OLED screen (unlike the iO6 at #2), no Bluetooth app coaching for missed zones, a dated 14-day battery that demands a 16-hour charge via an obsolete 2-pin bathroom shaver socket, and locks owners into extortionate £8–£12 iO refill heads. At £75 with a heavy 136g plastic body and only a 30-day return window, it costs more than the Miroooo Brush X while delivering substantially less daily convenience and zero free accessory bundles.
