Thirteen pieces, and the three you use
A kit is sold on the number of attachments and lived with on three of them. What separates a useful kit from a drawer of plastic is whether the attachments cover different jobs — beard, body, nose, detail edging — or the same job at four lengths. Every attachment shares one motor and one battery, and the stated runtime does not say which head it was measured with. We list what each attachment is for, the guard steps supplied, whether the head is rinsable, and what the kit is stored in, because a thirteen-piece set without a case is a set that loses pieces. The all-in-one kit guide ranks the models here, and two comparisons set them side by side: AIO3545 / MG3946 and AIO7565 / MG7962.
9-in-1 · 12 lengths, 0.5–12 mm (0.02 to 0.47 in) · nose trimmer · no oiling · 90 min
Nine attachments covering beard, hair, nose and ear hair and body, with twelve lengths from 0.5 to 12 mm (0.02 to 0.47 in), an intimate comb that shields the skin, and blades Philips states never need oiling.
Best for: One tool for everything, on a body that will not be oiled and cleaned on a schedule.

The number of available heights decides what the appliance can genuinely do: short beard, long beard, hair, body.
A multigroomer is used more often than a dedicated trimmer. Runtime decides how often it is recharged.
An entry kit already covers beard, hair, nose and body. The lowest recorded price on the shelf; today's price sits beside it.
For ordinary use, often. Each head does a little less well than the corresponding specialized appliance; anyone trimming a beard to the quarter-millimeter will prefer a dedicated beard trimmer.
Appliance off, pulling straight without forcing sideways. Bent heads no longer refit correctly.
Not necessarily, even on an appliance declared waterproof. The manual specifies head by head.
On a short, uniform cut, yes. The block is often narrower than a hair clipper's, which lengthens the work.
All heads with moving teeth, yes. Foil and precision-blade heads follow the maker's instructions.
Heads separate in a case or a holder. A dirty head left fitted clogs and seizes.
No: heads that demand more effort use more. The advertised runtime generally corresponds to the most favorable configuration.
Not always, and it is a question to ask before buying: a broken head with no replacement available can take the device out of service.
A multigroomer does everything a little less well than a dedicated appliance, which is enough for most daily uses. Check head by head what goes under water, oil every head with moving teeth, and store them detached — a dirty head left in place seizes.
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.
