Who Should Buy This
This simplehuman 45L semi-Round Sensor can in Matte Black Steel is perfect for anyone who wants a clean and easy way to manage trash in the bathroom. It is great for people who like modern design and want a trash can that opens automatically. The 45-liter size is good for medium to large bathrooms. If you want a durable and stylish trash can that helps keep your space neat, this is a good choice. It is also ideal for those who appreciate hands-free convenience and want to avoid touching the lid.
However, this product might not be the best for small bathrooms or tight spaces because it is quite large. If you have a limited budget, the $169.99 price could be too high. Also, if you prefer a simple manual trash can without sensors, this one may be more complex than you need. People who do not want to worry about battery replacement or sensor maintenance might want to look for a simpler model.

Our Testing Experience
First Impressions
When I first unpacked the simplehuman 45L Semi-Round Sensor Can in Matte Black Steel, I was impressed by its sleek look and solid build. The size felt just right for my kitchen space, not too big or too small. Setting it up was easy—I just placed the liner inside and the outer lid lifted smoothly without any hassle. The sensor seemed smart right away, as it didn’t open randomly when I moved nearby. I was curious to see how well it would work with daily kitchen messes.
Daily Use
Over the next few days, I tested the sensor can during meal prep and clean-up. The adaptive motion sensor worked like a charm. It opened as I approached with hands full and didn’t close too quickly or unexpectedly. I never had to touch the lid, which kept things hygienic and simple. The lid’s smooth, steady movement was noticeable—I liked that it didn’t slam shut but closed gently every time. Also, lifting the outer lid to change the liner was super easy and neat, no fumbling or mess at all.
Key Features in Action
The adaptive motion sensor really stood out. It adjusted well to my movements and the lighting in the kitchen, avoiding false triggers that I’ve experienced with other sensor bins. The planetary gear system made the lid open and close quietly and smoothly, which was a big plus for me. The design with the outer lid lifting up made changing liners quick and clean—no need to remove the whole top or struggle with a bucket inside. This kept everything looking tidy, even when the bin was full.
Long-Term Performance
After using the simplehuman sensor can for a few weeks, it still works flawlessly. The sensor remains reliable and hasn’t lost sensitivity or started closing unexpectedly. The matte black steel finish holds up well, resisting fingerprints and scratches better than I expected. Overall, it’s been a great addition to my kitchen, combining smart technology with practical design. I feel confident this bin will last a long time and keep my space neat and convenient.
