TL;DR
Nit hoovers (electric lice combs) use suction to remove lice and nits. They can help but aren't a substitute for treatment — you still need to kill live lice with a silicone- or oil-based product or wet combing.
What is a nit hoover?
A nit hoover is a battery-powered device with a fine comb and suction. As you comb through hair, it draws lice and eggs into a chamber. It can make removal easier, especially for nits that cling to hair.
How do nit hoovers work?
You comb section by section from roots to ends. The suction pulls lice and nits into a disposable filter. They're available from pharmacies and online. Combine with a proper treatment — the hoover removes debris but doesn't kill lice. Check first. For stubborn cases, find a clinic. See best nit combs.
