Premium Beard Trimmer with Steel Build

The Norelco BT9810/40 Series 9000 is a premium beard, hair and stubble trimmer built with a full steel head and self-sharpening blades. Beard Sense Technology adapts motor power to hair density for an even cut in every pass. It suits users who want a durable, all-in-one grooming tool with precise length control.

Upgrade from Basic Trimmers with Fixed Guards

This model replaces trimmers that offer fewer length steps or plastic guards that flex during use. The quick-adjust zoom wheel locks in 30 settings at .2 mm increments from .4 mm to 10 mm, removing the need to swap multiple attachments. The jump is worth it when you want a single reinforced guard that holds its position on thick or coarse hair.

Consistent Cordless Power for Extended Sessions

A lithium-ion battery delivers 120 minutes of runtime after a 1 hour charge, maintaining cutting speed throughout the session without fading. The trimmer is 100% waterproof for wet or dry use and easy rinsing. A battery indicator prevents unexpected shutdowns, while blade oil and a premium travel case support long-term performance.

Questions about this item

What guard attachment comes with the BT9810/40 for length control?

One reinforced guard attachment is included and works with the zoom wheel to deliver 30 length settings from 0.4 mm to 10 mm in 0.2 mm increments.

How do you set a precise cutting length on the zoom wheel?

Spin the quick-adjust zoom wheel until the desired setting clicks into place; each click moves the guard 0.2 mm so you can lock in any of the 30 lengths between 1/64" and 25/64".

When should the supplied blade oil be applied to the steel blades?

Put a drop of the included oil on the full-steel blades after cleaning and drying the trimmer; regular oiling keeps the self-sharpening edges cutting evenly and reduces friction on dense hair.
