Typical cleaning methods include rinsing the heads under the tap, using a small brush to remove trapped hairs, and applying blade lubrication as recommended. Some models offer automated clean‑and‑charge stations that clean, lubricate and dry the shaver for you.
Many models are marketed as wet/dry or waterproof. Some are fully waterproof and can be rinsed or used in the shower, while others are described as wet/dry or showerproof for cleaning and wet shaving. Waterproof capability varies by model, so check the product details before use.
