Three heads, and how far they tilt
A rotary shaver works in circles, which is why it suits a neck that grows in several directions and a face that is not shaved every day. Three round heads on independent pivots follow the jaw; the number of directions each head tilts in is a published figure and it is the one that separates the ranges. Beyond that, three things decide the years you get from it: whether it is rated for wet use, whether a cleaning station is supported, and what a replacement head costs — because it is a consumable, and the cheapest shaver is rarely the cheapest over three years.
27 self-sharpening blades · 55,000 cuts/min · 5D flex heads · wet & dry
The entry Philips rotary: 27 self-sharpening blades cutting 55,000 times a minute, heads that move in five dimensions, SkinProtect, and stainless blades Philips states keep sharpening themselves for two years.
Best for: A first electric shaver, for a face shaved in the shower a few times a week.
27 blades · 55,000 cuts/min · 4-way flex heads · wet & dry
The 3000X: the same PowerCut system and two-year self-sharpening blades as the Series 3000, on spring-mounted heads Philips describes as flexing in four directions rather than five.
Best for: The same shave as the Series 3000, from a reference that can actually be ordered on amazon.com.

360° heads · click-on precision trimmer · 100% waterproof · 50 min
Fully flexible heads that turn through 360 degrees, a click-on precision trimmer for mustache and sideburns, a head that opens for rinsing, and an hour's charge for fifty minutes of use.
Best for: Shaving every day or two, with the head rinsed rather than brushed.
≈ $120
SkinIQ · 45 blades · 90,000 cuts/min · charging stand · 5-year warranty
Philips's top rotary in this group: 45 SteelPrecision blades cutting 90,000 times a minute, a micro-bead coating stated to add 30% glide, SkinIQ, a charging stand and travel case, and a five-year warranty.
Best for: Shaving daily, on a three-day beard, with the shaver living on a stand rather than in a drawer.
Cutting speed takes only two values on this shelf: three of the four state 55,000 cuts a minute and one states 90,000. So speed here is a single step at the top of the range rather than a ladder, and it is the step that matters when you are going over several days of growth.
The entry models use the same 27-blade head and the same 55,000 cuts a minute as the mid one. What they do not publish is a runtime, a quick-charge figure, or a water rating beyond wet and dry use in the shower. The saving is real, and so is the missing information.
Three of these four share the same 27-blade head. What the mid model adds over the entry pair is what the entry pair leave unstated: a published runtime, a five-minute charge for one shave, a head that opens and rinses under the tap, and a stated 100% waterproof rating.
Rotary follows the contours of face and neck better; foil shaves closer on flat surfaces. Beard type and face shape decide, and no figure on this page changes that choice.
In small circles, without pressing. Pressing irritates the skin without shaving closer, and it is the single most common reason a rotary shave feels worse than it should.
Only where the manufacturer states it, and on this shelf that statement comes in two forms: two models state wet and dry use in the shower, and two state 100% waterproof. Read the sheet for the model rather than assuming the range behaves alike.
Nobody publishes a figure that would answer it. Three of these four use a 27-blade head and the top one uses 45, which is a count of cutting edges rather than a measured result. Treat it as a specification, not as a promise.
Each maker describes head movement in its own words, and across these four shavers there are four such descriptions. They are not a common scale, so a shaver described in degrees is not demonstrably more flexible than one described in dimensions.
All four models here publish a self-sharpening claim stated at two years. It describes the sharpening, not a service life, and the replacement interval is published separately by the manufacturer. A shave that pulls, or that needs several passes where one used to do, is the practical signal.
Manufacturers publish a replacement schedule, and it is worth pricing the heads at the same time as the shaver: on an entry-level model a replacement head can cost a large share of the machine, which changes which shaver is actually cheaper over three years.
Three causes, in the order worth checking: too much pressure, heads that have gone past their replacement interval, and going over the same area several times. Reducing the pressure is the first thing to try, because it costs nothing and it is the commonest of the three.
A pre-shave helps some skins glide and does nothing for others, so it is worth one trial rather than a rule. On very dry skin many people end up wet shaving instead, which the water rating on your model either permits or does not.
Rinsing in lukewarm water where the model allows it, otherwise a brush, and drying completely before reassembly so the contacts do not corrode. One of the shavers here publishes a head that opens at the press of a button and rinses under water; the others state what they allow on their own sheets.
Rarely, and not reliably even within one maker's range. The reference is printed on the head itself or given in the manual, and that reference rather than the shaver's model number is what a replacement is ordered against.
On the two models here that publish one, enough for a single shave. Both also publish a full-charge figure of an hour. The two entry models publish neither, so there is nothing to compare them on.
Rotary follows contours and foil shaves closer on the flat, so face shape decides as much as preference. Within this shelf the published figures separate into two groups rather than four: three models share a 27-blade head at 55,000 cuts a minute, and one steps up to 45 blades at 90,000. Everything else worth knowing is about what is stated and what is not — a runtime on two models of four, a water rating in two different forms, a warranty on one. Shave in small circles without pressing, price the replacement heads before you buy, and change them as soon as one pass stops being enough.
Specifications that fewer than four of these models in five publish are left out of this table. Keeping them would fill it with blanks and make a shared gap look like a difference.
