oneisall Pro Upgrade review

The quietest clipper in this group at under 49 dB, fully washable under the tap, with three and a half hours of runtime from a 2,000 mAh cell. It costs about the price of two bags of litter.

What we take from it The one to start with. Quiet enough for a cat, washable, and cheap enough that finding out your animal hates clippers costs almost nothing.

What it is

A cordless two-speed pet clipper: 6,000 to 6,800 rpm, a 2,000 mAh cell good for three and a half hours, an IPX7 body and a detachable blade. oneisall quotes under 49 dB.

Noise is the specification here

Everything else in this group is louder, including every grooming vacuum. For a cat, a small dog, or any animal that has already been frightened by a clipper once, that figure is not a nice-to-have — it is the entire reason to choose one machine over another. The quiet motor is what oneisall sells, and it is the right thing to sell.

Washable, properly

IPX7 covers the whole housing rather than just the head. Hair and skin oil are what stop a clipper cutting, and a tool you can rinse completely is a tool that stays sharp for its whole life rather than for a season.

What it will not do

Full clips on a thick double coat. It is a two-speed hobby machine, and it will slow where a salon clipper keeps its speed. If you are clipping a large dog to the skin twice a year, look at the Wahl or the Heiniger further down this page and pay four to ten times as much for the privilege.

The questions owners ask

Is under 49 dB really quieter than the rest?

By the published figures, yes: 49 dB here, 55 dB on the metal-comb oneisall, 60 to 75 dB on the grooming vacuums. Manufacturer measurements are not comparable methods, but a spread that wide is a real difference, and on a cat it is the difference between a session and a fight.

What does IPX7 mean in practice?

The whole body can be rinsed under running water, not just the blade. On a tool that fills with hair and skin oil, that is the difference between a clipper that keeps cutting and one that gets sticky and gets thrown away. Dry it fully before charging.

Will it handle a matted coat?

No, and neither will anything else at this price. A mat sits against the skin and has to be cut out by someone who can see what is underneath — that is a job for a groomer or a vet, not for a home clipper of any make.
