MOPUP Motion Sensor Trash Can 3.5 Gal Slim White — Automatic Hands‑Free, Vacuum‑Seal Liner

The MOPUP 3.5‑gallon motion sensor trash can is a slim automatic bin that opens hands‑free, secures the liner by vacuum seal, and fits narrow spaces like bathrooms, bedrooms, and offices.

This compact white trash can combines space-saving dimensions with smart, touchless operation so you can remove waste without bending or touching the lid. Designed for small rooms, it uses a quick‑response infrared sensor, air‑seal liner technology and a damped lid for quiet closing. The unit runs on AA batteries and includes features intended to keep bags snug, contain odors, and operate reliably in humid environments.

How fast and reliable is the sensor when you need to toss rubbish?

The built‑in sensor detects motion within about 6–10 inches and responds in roughly 0.3 seconds, so the lid lifts the instant you approach. After you move away, the lid closes automatically after around six seconds for hands‑free convenience.

• Infrared detection activates in under half a second.
• 6–10 inch sensing range suitable for hand or knee activation.
• Automatic 6‑second close to reduce lingering odors.
• Operates on four AA batteries (not included); indicator shows power status.

What makes the bag stay neatly attached inside the bin?

MOPUP’s internal air inlet and outlet create a partial vacuum when the lid is closed, pressing the liner against the can’s inner wall. This self‑attach effect reduces slipping and maximizes usable volume, particularly helpful in narrower containers.

• Vacuum seal holds standard small liners tightly in place.
• Works best with bags sized for a 3.5‑gallon (14 L) capacity.
• Helps prevent bag collapse and improves interior capacity use.
• Simplifies liner changes — fewer manual tucks required.

Will this trash can be quiet and durable enough for nightly use?

The lid uses air‑damping technology and an upgraded control chip for slow, silent opening and closing, minimizing disturbance. The design and materials are chosen to sustain sensor performance in splashy or humid spots like bathrooms.

• Air‑damped lid prevents loud slams.
• Quiet motor and slow close suitable for bedrooms and night use.
• Electronic components calibrated for consistent lifetime operation.
• Sealed lid design helps limit odor escape.

How compact is it and where does it fit best in my home?

The 3.5‑gallon size and narrow 6.3‑inch opening let the bin tuck into tight corners, beside vanities, or next to desks without taking up floor space. A minimalist white finish blends cleanly into modern bathrooms, powder rooms, and small offices.

• 14‑liter (3.5 gal) capacity balances compactness and usable volume.
• 6.3‑inch wide mouth optimizes placement and disposal access.
• Slim profile fits narrow gaps and tight layouts.
• White plastic surface wipes clean and resists humid environments.
