In this article, we dive deep into the main differences between the SURI 1.0 electric toothbrush and its upgraded version, the SURI 2.0. Although they look nearly identical at first glance, the second generation introduces several meaningful updates that may influence your decision depending on what you value most.

Main Differences Between SURI 1.0 and SURI 2.0
Here’s a breakdown of the most relevant changes and innovations:
- Charging System and Contact Points
The SURI 1.0 uses two gold charging contacts at the base to connect to its charger or travel case. The newer SURI 2.0 removes those contacts entirely and switches to inductive (wireless) charging for both the stand and case. - Motor and Power
While both brushes deliver around 33,000 vibrations per minute, the SURI 2.0 features a new motor that provides up to 25% more brushing intensity. - Pressure Sensor (Gum Protection)
One major improvement is the pressure sensor, absent in the SURI 1.0. It detects when you’re pressing too hard and sends vibration alerts or stops the bristles until the pressure is reduced. - Travel Lock Mode
The SURI 2.0 introduces a travel lock that disables the power button to prevent accidental activation—something the SURI 1.0 lacks. - Brush Head Fitting
Both use identical brush heads, but the SURI 2.0 allows for easier attachment and removal, requiring less grip and force. - Battery Life and Charging Time
The SURI 1.0 advertises over 40 days of use, while the SURI 2.0 promises “1+ month.” In real tests, the SURI 1.0 achieved around 42 days per charge, while the SURI 2.0 averaged about 38 days—likely due to the stronger motor.
Charging time also increased slightly—from 3–4 hours on the SURI 1.0 to up to 7 hours on the SURI 2.0. - Travel Case with Upgraded UV-C Sanitizer
The travel case now includes a built-in battery to power the UV-C light even when unplugged. The SURI 1.0 required external power for sterilization. - Weight, Design, and Finish
The SURI 2.0 is lighter (≈ 75 g vs 84 g).
It also features an improved coating to prevent wear and includes a plant-based brush head cover, which the SURI 1.0 did not. - Launch Price
The SURI 2.0 debuted at roughly 10% higher retail price compared to the SURI 1.0.
Performance and User Experience
Cleaning Efficiency
Both models perform equally well when it comes to cleaning capability. The main advantage of the SURI 2.0 lies in convenience features like the pressure sensor, travel lock, and better UV-C case.
Battery Trade-off
The SURI 1.0 offers slightly better battery life, but the new motor and features of the 2.0 justify a small reduction in runtime.
For most users, those few extra days are not decisive.
Durability and Sustainability
SURI is known for its eco-friendly design—an aluminum body, brush heads made from plant-based materials like corn and castor oil, and a recycling program for used heads.
The SURI 1.0 faced occasional issues with corrosion on charging pins due to water exposure—a flaw the 2.0 addresses by switching to wireless charging.
Tom’s Guide notes that this fix resolves one of the most annoying problems of the first version.
Which Version Is Right for You?
Choose SURI 1.0 If…
- You’re budget-conscious and want the most affordable option.
- You prioritize brushing performance over new features.
- You rarely use the UV-C case or don’t mind plugging it in.
Choose SURI 2.0 If…
- You want gum protection via a pressure sensor.
- You travel often and benefit from a travel lock.
- You prefer a wireless UV-C case with its own battery.
- You want a more durable, corrosion-resistant handle.
Experts agree that the SURI 2.0 represents a thoughtful evolution of the original, solving its biggest weaknesses without compromising performance.
According to Electric Teeth, the modest price increase is well worth it for the added convenience.
Conclusion: Is the SURI 2.0 Worth the Upgrade?
In summary, if you already own a SURI 1.0 and are satisfied with it, upgrading isn’t strictly necessary. However, if you’re buying for the first time, the SURI 2.0 is the better long-term investment thanks to its added comfort, smarter design, and better usability.
The wireless charging, pressure sensor, built-in UV-C battery case, and travel lock make it a more polished and mature product. The slightly shorter battery life is a fair trade-off for these practical improvements.
