Cleaning Action and Modes
Oral-B Smart 6
An oscillating-rotating cleaning motion sits at the heart of this electric toothbrush's everyday performance, shaping how it adapts to different brushing needs across its included 5 cleaning modes. In practical use, modes are selected to match the goal, and brushing should be done along the gumline with steady, light pressure until coverage feels complete. This single-handle, multi-routine approach is designed to keep the feel of brushing consistent across the mouth.
Oral-B Pro 1 600
Oscillating-rotating motion drives the cleaning action of the Oral-B, paired with a built-in pressure sensor intended to help reduce hard brushing. The handle uses a rotating head that moves in small, repeated cycles to help clean teeth and reach the gumline. The model offers 1 brushing mode, 3D Cleaning, with no separate sensitivity or whitening settings. With the pressure sensor in place, guiding the brush gently supports effective contact, because excessive force may trigger the sensor and affect contact. This makes the electric toothbrush best suited to simple daily routines with consistent technique.
Battery Life and Charging
Oral-B Smart 6
Battery life and charging on the Oral-B affects day-to-day convenience, particularly when brushing at irregular times or travelling. The handle is described as an app-connected electric toothbrush. A regular routine is therefore necessary to avoid the handle running out mid-brush, with home charging before trips being the practical approach. It includes a travel case for portability, but it does not replace knowing when to recharge. Battery performance remains a practical uncertainty until tested.
Oral-B Pro 1 600
Battery life depends on how the toothbrush is used, and charging convenience will matter for anyone who brushes more than once per day. The Oral-B is an electric handle with one cleaning mode, and its battery performance is influenced by regular daily use patterns. Charging uses the included 2-pin UK plug, so ease of use depends on access to a suitable home outlet. Charging routines can be planned around a bathroom setup.
Pressure Sensor and Timer
Oral-B Smart 6
A practical way to judge an electric toothbrush is to focus on technique support as well as cleaning. In this respect, the pressure sensor and timer are the key features to look for on a brushing routine, since they can help avoid pressing too hard and keep time consistent. For the electric toothbrush, the available information does not specify exact timer lengths or how the pressure threshold behaves. As a result, performance expectations should be treated as general, and any specific behaviour around pressure alerts or session timing remains not stated.
Oral-B Pro 1 600
A built-in pressure sensor helps keep brushing within a safer range, and it works alongside the toothbrush's timing features to guide consistent sessions. The sensor helps reduce the chance of brushing too hard, which matters because excessive force can irritate gums. The timing feature then encourages users to spread attention across the mouth, rather than rushing one area. This combination suits adults who want a routine without constant monitoring. The device has only one cleaning mode, so it cannot adapt to different needs, and correct handling is still required.
Brush Heads and Running Costs
Oral-B Smart 6
Brush heads shape day-to-day cleaning results and ongoing running costs because they wear down and need replacing. The Oral-B is sold with three toothbrush heads, so replacement heads must be considered once the initial set is used up. For best results, a head should be swapped when the bristles look flattened, since worn bristles clean less effectively. Using the wrong head model can also reduce fit and comfort, so compatibility matters.
Oral-B Pro 1 600
Choosing the right replacement heads is a key part of owning the electric toothbrush. The handle covers the motor and control features, while the brush head is the cleaning component. The title mentions a package includes 1 toothbrush head, so ongoing use depends on buying compatible replacement heads separately. Replacement head pricing and availability vary by supplier. Each head is designed to be swapped when the bristles wear, as worn bristles clean less effectively, which is a direct factor in running costs. If a single user mode and 3D cleaning are selected, fewer head types may be needed, but budgeting for ongoing head replacements remains necessary.
Smart Features and Travel
Oral-B Smart 6
Smart features on the electric toothbrush focus on app connectivity. The handle can link to a companion app to help guide brushing routines, rather than relying only on the built-in cleaning modes. In daily use, app support can add structure, although technique and timing can still vary without it. For travel, the included travel case supports transport and helps protect the handle and heads when packed. The toothbrush includes 5 cleaning modes and whitening, so brushing is possible without checking the app.
Oral-B Pro 1 600
The Oral-B Pro 1 600 is built around basic brushing functions, with no product information detailing Bluetooth connectivity, a companion phone app, or on-screen coaching. That lack of smart features keeps setup straightforward for travel, with no pairing required. The handle includes a pressure sensor, which can help reduce overly hard scrubbing when the brush is used away from home. Overall, it is aimed at users who want a standalone electric toothbrush.
Who Is This Electric Toothbrush For?
Oral-B Smart 6
This electric toothbrush is a good fit for adults who want an oscillating-rotating handle with built-in options and optional app help. It suits people who prefer choosing between five cleaning modes, and who like guidance via app connectivity, while users who skip the app can still use the built-in settings. It is also aimed at travellers, with a travel case included in the box. It may not suit users who want a basic, no-frills brush, because app connectivity and multiple modes add extra choice. Three brush heads are included, and compatible replacement heads are supported for ongoing use.
Oral-B Pro 1 600
This electric toothbrush suits people who want an uncomplicated, standalone brushing routine without app-based guidance. It is designed for adults and uses an oscillating-rotating action with a single cleaning mode described as 3D cleaning. A pressure sensor helps users avoid brushing too hard, which can be relevant for sensitive gums or beginners. It also fits shoppers who prefer a simple handle and a single toothbrush head setup, with no extra modes to select. Those who want multiple settings, smart tracking, or detailed custom coaching may find the feature set limited. Travel support is only covered in basic terms, as no specific details are provided.

Our pick is the Oral-B Smart 6 (our score 9.3/10) - A practical electric toothbrush (oscillating-rotating, 5 cleaning modes) that helps you brush more effectively than a manual brush. The Oral-B Pro 1 600 is still worth it if it is cheaper when you check, or if it better matches your specific needs.
