Our verdict

The Philips 9000 Series is the most different clipper in this guide, and that difference is its entire case. Instead of swapping guards, the user dials a length by touch through Digital Swipe, choosing from 400 settings between 1 mm and 42 mm, and saves preferred lengths for repeat cuts. Titanium blades need no oiling, run time is 120 minutes with a 1 hour charge, and cleaning is simple. The cost is control style: digital controls feel fiddly to lever lovers, motorized combs move slowly between lengths, and the feature set exceeds what a basic buzz cut needs.

What we like

  • Four hundred length settings from 1 mm to 42 mm in 0.01 mm steps via Digital Swipe give finer control than a guard set
  • Self-sharpening titanium blades with DualCut technology need no oiling
  • One hundred twenty minutes of run time with a 1 hour charge covers repeated cuts
  • Memory for preferred lengths saves setup time on repeat cuts, per owner reports

What to watch out for

  • The digital controls feel fiddly for users who prefer a simple lever
  • The motorized comb movement can feel slow when changing lengths
  • The premium feature set is more than a basic buzz cut requires

Who it is for

Users who repeat one or two exact lengths and want to set them precisely without handling a guard set.

Digital length control, honestly assessed

Four hundred settings in 0.01 mm steps sound excessive until you repeat a cut: the difference between a good repeat and a visible change can be a fraction of a millimetre, and a guard set jumps in larger steps. Digital Swipe lets the user touch a length and have motorized combs move to it, and memory for preferred lengths saves setup time on repeat cuts, per owner reports. The trade-off is speed of change: motorized combs move more slowly than a hand swapping a guard, so users who change length many times per cut will notice the pause.

Blades and maintenance

Self-sharpening titanium blades with DualCut technology cut cleanly and, importantly, need no oiling. That removes the maintenance step many home users forget, and it simplifies cleaning after a cut. For a user who wants a clipper that is ready, cuts precisely and asks little in return, that low maintenance profile is a genuine advantage over traditional steel blades that need regular oiling.

Who should not buy it

Anyone who prefers a simple lever, changes length constantly during a cut, or only does basic buzz cuts should look elsewhere. The digital controls feel fiddly to users who want tactile simplicity, the motorized movement can feel slow when changing lengths, and the premium feature set is more than a basic cut requires. This is a precision tool for repeatable lengths, not a general purpose clipper for every household, and judging it as the latter misses its point.

Questions, answered

Are 400 length settings actually useful?

They are useful for repeating an exact length, because small differences matter when the same style is cut every few weeks. For a first cut or a simple buzz cut, most of those settings will never be used, and a guard set is simpler. The value depends entirely on whether repeat precision is your main need.

Do I need to oil the Philips blades?

No. The blades need no oiling, which simplifies maintenance and cleaning compared with traditional steel blades. That is one of the model's practical advantages for home users who forget blade maintenance.

Is the Philips 9000 Series good for fades?

It can do a gradual length change, but it is not a fade specialist. Fade work relies on a taper lever moved constantly mid cut, and the Philips digital and motorized system is slower at that kind of continuous adjustment than a lever clipper such as the Magic Clip. For fades, buy a fade clipper; for exact repeat lengths, buy the Philips.
