Braun Series 9 PRO+ review
Five published cutting elements, sixty minutes of runtime, and the one figure most reviews never mention: how often you will be buying a new head.

This page carries affiliate links: if you buy through one we earn a commission at no extra cost to you, and it does not change the order of the picks. Full disclosure.
The short version
Buy it if you want the closest electric shave and a running cost you can plan. Five published cutting elements each with a stated job, plus a titanium-coated ProLift blade. 60 minutes of runtime, a five-minute charge for a full shave, fully waterproof. And Braun publishes replacement guidance of about 18 months for the foil and cutter block - which almost nobody else in this category does.

Five elements, each with a published job
This is unusually good disclosure for the category. Braun does not say “advanced five-element system” and leave it there; it says what each element is for:
- Two Ultra Thin gliding foils for shorter hairs.
- A protective SkinGuard, sitting between the cutting elements and the skin. This is the element that matters if your skin reacts, and it is a named component rather than a claim about gentleness.
- A Direct & Cut blade for hairs growing in any direction - the thing a straight-line foil normally struggles with.
- A Lift & Cut blade for flat-lying hairs.
- A titanium-coated ProLift blade on top of those.
Compare that to the Series 7, for which Braun publishes no element count at all, and the Panasonic Arc5, which publishes five blades and a motor speed but no per-element function. Braun's is the most legible specification in the category.
The number nobody quotes
Braun's parts guidance says to change the foil and cutter block about every 18 months to maintain maximum performance. That single figure is the difference between a shaver whose cost of ownership you can calculate and one whose you cannot.
It matters because head cassettes are proprietary. There is no commodity standard for electric shaver heads the way there is for double-edge blades, so Braun sets the price and no competition holds it down. A maker that at least tells you how often you will be paying it is doing more than its competitors.
Find the cassette price before you buy the shaver, multiply by the number of eighteen-month periods you expect to own it, and add it to the sticker. The calculator will do the per-shave arithmetic once you have both numbers.
Sixty minutes, and the five that actually matter
60 minutes of Li-Ion runtime is the longest of the shavers on this site, and at a three-minute shave that is roughly three weeks. Useful, and past the point where more would change anything.
The figure that removes charging from your life is the five-minute quick charge for one full shave. That is what makes a flat battery a non-event rather than a reason to reach for something else, and it is a published figure on both Brauns here.
What Braun does not publish
Motor speed. Panasonic publishes 14,000 cuts per minute and up to 70,000 cross-cuts for the Arc5; Braun publishes no equivalent, which means the two cannot be compared on how fast they actually cut.
Also absent: country of manufacture on the product page, and any noise figure. The second is a genuine daily consideration - foils are louder than rotaries, and nobody in the category publishes decibels - and it is one of the few places where our disclosure axis cannot help you because there is nothing to score.
Who should buy something else
If your beard is dense and you want the shave over fast, the Panasonic Arc5 publishes more about how it cuts than anything here. If your face is contoured or your hair is coarse and curly, a rotary may suit you better - the head-to-head covers it.
And if what you actually want is for your face to stop reacting, the sensitive-skin roundup starts somewhere cheaper and, for ingrown hairs specifically, better.

Our pickThe closest electric shave
Braun Series 9 PRO+
Five synchronized shaving elements — two gliding foils, a SkinGuard, a Direct & Cut blade and a Lift & Cut blade — plus a titanium-coated ProLift blade, 60 minutes of runtime, a five-minute charge for one shave, and it is fully waterproof. If the requirement is 'as close as an electric gets', this is the answer and there is not much argument about it.

What it gets right
- Five published cutting elements, each with a stated job, plus the ProLift blade
- 60-minute Li-Ion runtime, the longest of the shavers here
- 5-minute quick charge for a full shave
- 100% waterproof; usable wet with lather
Flaws
- Replacement head cassettes are proprietary and are the real long-run cost
- Braun's published 18-month replacement interval is guidance on its parts pages rather than a figure on the product specification, so it is easy to miss before you buy
- The most expensive way to remove hair in this ledger
The working behind the 7.4
- How long it lasts: not scored
- Not scored. This is a durable item, not a consumable, so how long it lasts is an assumption about service life rather than something the pack size tells us.
- Ease of switching: 9.0
- Wet-and-dry with 60 minutes of runtime and a 5-minute quick charge; nothing about daily use requires a decision (++). Braun publishes an 18-month foil-and-cutter replacement interval, which at least makes the running cost plannable (+), but the cassettes are proprietary so the price of it is Braun's to set (-).
- Refill economics: 4.0
- Only this maker's refill fits, so the ongoing price is set by the maker rather than by a market. This is where the real cost of ownership hides.
- What the maker publishes: 8.0
- 4 of 5 specifications a buyer would expect are published: runtimeMin, cuttingElements, waterproof, headReplacementMonths. Not published: chargeMin. 4 / 5 x 10 = 8.0.
Axes with no published input are dropped and the remaining weights re-normalized, so a product is not punished for a category where an axis does not apply. Specifications compiled 3 September 2026 from Braun Series 9 PRO+ published specifications.

Questions people actually ask
How often should I replace the Series 9 head?
Braun's parts guidance is about every 18 months to maintain maximum performance. It is worth finding the price of a replacement cassette before you buy the shaver, because it is the largest ongoing cost of owning one and it is proprietary.
What are the five cutting elements?
Braun publishes them as two Ultra Thin gliding foils for shorter hairs, a protective SkinGuard, a Direct & Cut blade for hairs growing in any direction, and a Lift & Cut blade for flat-lying hairs. The ProLift blade is a titanium-coated element on top of those.
Is the Series 9 worth it over the Series 7?
Braun does not publish a cutting-element count for the Series 7, so the gap cannot be quantified from the specifications - which is an honest answer rather than a helpful one. Both publish the same 5-minute quick charge and full waterproofing. For most faces the Series 7 is the sensible stopping point.
Can you use it wet with shaving gel?
Yes. Braun publishes it as 100% waterproof for wet and dry use. If you are getting irritation, shaving wet with a thin gel is the first thing to try - the guide is here.
