Lightweight and versatile, the model converts between stick and handheld modes and is suitable for cleaning a variety of floor types and multi‑room apartments.

Advantages

The Deerma DEM-T20W offers simultaneous vacuuming and mopping, reducing the need for separate appliances. Its 9‑cone cyclone design improves dust separation for stable suction and better cleaning performance. The brushless motor delivers consistent 18 kPa suction to pick up fine dust and larger debris. A five‑layer filtration system helps contain allergens and fine particles, and the one‑touch dust bin emptying ensures hygienic removal of dirt without direct contact. Compact dimensions and low weight (2.27 kg) make handling and maneuvering easier during daily cleaning tasks.

Operate the vacuum with steady passes over floors and surfaces; use the handheld configuration for furniture, stairs and tight spaces. After use, press the one‑touch release to empty the dust container and rinse removable parts according to the maintenance instructions.

Recommendations

For best performance, charge the 5000 mAh battery fully before extended cleaning sessions, empty the dust container regularly to maintain suction, and clean or replace filters as needed to preserve filtration efficiency. Use the 0.2 L water tank only with clean water and avoid harsh chemicals to protect the mopping system.
