MOPALL Motion-Sensor Trash Can, 3.5 Gallons

What matters most

Some bathroom bins are simple containers, this one is built for people who want to avoid touching the lid and the bag during everyday cleanup.

A motion sensor opens the lid, and the bin closes it after five seconds without activity. That hands-free setup can be useful when you’re at the sink with a used tissue or cotton pad in hand.

It also pairs a 3.5-gallon capacity with an auto-bag suction feature and a one-pull sealing mechanism. The idea is to keep the bag against the bin’s inner walls, then make removal less of a hands-on task.

The listed sensor range is 11.8 inches, and the lid is specified to open in 0.3 seconds. Keep in mind that the sensor has a defined range, so placement matters: you’ll want to be able to reach it naturally from where you stand. It’s not described as a lid that stays open indefinitely.

Charging is via Type-C rather than disposable AA batteries. The maker says a full charge can last for weeks, but doesn’t provide usage conditions for that estimate. Its construction is described as moisture-proof and splash-resistant for humid areas, that is not the same as a claim that the bin can be submerged or rinsed under running water.

A solid pick if you want touch-free opening and a bag-sealing feature in one bathroom or bedroom bin. It might not be a great match if you need a larger-capacity wastebasket or want a lid you can leave open while cleaning.

How to use it

Place the bin where you can bring waste within the sensor’s stated range, then let the lid open as you approach. Once you’ve dropped something in, it closes after five seconds without activity. For a bathroom routine, that could mean tossing a used tissue without reaching for a pedal or lifting a lid by hand.

When the bag is full, the pull-to-seal feature is intended to let you close and lift it with one pull, avoiding a knot and reducing contact with the waste. The suction feature is designed to hold the bag flush against the interior rather than leave loose folds taking up space. No specific bag size or replacement-bag requirement is provided, so don’t assume every liner will fit the same way.

Practical tips

Think about the spot before choosing this bin. A position beside a vanity or desk may make the sensor easy to reach, while a tight corner could make its motion-triggered opening less convenient. The listed 3.5-gallon capacity is aimed at smaller rooms and routine waste, not a high-volume kitchen or shared workspace.

Because it uses rechargeable power, you’ll need access to Type-C charging when the battery needs a top-up. The description doesn’t state a charging time or battery indicator details. For humid rooms, the splash-resistant design is relevant, but placing electronics near direct water spray would go beyond what the product information confirms.

Compared with a basic open-top bin, this one adds a closing lid, touch-free access, and bag sealing. Those features may be worthwhile if you value less handling, if you mainly want the simplest possible container, they may be more than you need.

Questions before you buy

Does the lid stay open? It is described as closing automatically after five seconds without activity, so it isn’t presented as a lid that remains open until you close it yourself.

Does it use disposable batteries? The listed power setup is rechargeable with a Type-C port, rather than AA batteries.

Can you seal the bag without tying a knot? The one-pull feature is designed to seal and lift the bag with a single pull. The product details don’t specify which liners are compatible.

Final verdict

This MOPALL bin makes the most sense when touch-free opening and simpler bag removal matter more than maximum capacity or a no-frills design. Its 3.5-gallon size and defined sensor range are the key fit checks: choose it for a compact bathroom, bedroom, or office setup where you can position it within reach. Skip it if you need a larger wastebasket, a lid that stays open, or clearer guidance on bag compatibility before buying.
