The short answer: If you want a budget friendly smart bin with voice control and a modern look, the Smarter trash can is a great pick. If you value build quality, sleek design, and a reliable sensor that rarely fails, Simplehuman is the premium choice. Your final decision depends on your kitchen space, tech preferences, and budget.
When you bring a trash can into your kitchen, it becomes part of your daily life. Simplehuman has built a reputation for premium stainless steel finishes that resist fingerprints. Their step cans and sensor cans feel solid, with a weighted base that prevents tipping. The lid closes slowly and quietly, which is a huge plus if you have kids or pets.
Smarter, on the other hand, goes for a more futuristic look with a cylindrical shape and a matte finish. It is lighter and less expensive, but the plastic build feels less durable. Over time, you might notice scratches or wear, especially if you push it around. If you care about aesthetics and longevity, Simplehuman often wins in this category.
The core of a smart bin is its motion sensor. Simplehuman uses an infrared sensor that is highly responsive. You can wave your hand or knee near the lid and it opens within 0.2 seconds. The sensor has a range of about 8 inches, and it stops false triggers from pets walking by. The lid stays open for 4 seconds after the movement stops, giving you enough time to toss trash without it closing on you.
Smarter also uses a sensor, but it has a slight delay. It takes about a second to open, which can feel sluggish when you have your hands full. The sensor range is shorter, around 6 inches, so you need to be closer. However, Smarter offers voice control via Alexa or Google Assistant. You can say “Alexa, open the trash” and it responds. That is a nice trick, but is it practical? If your hands are covered in raw chicken juice, voice control might be your best friend.
Simplehuman bins are battery powered, using 6 D batteries for their sensor models. Depending on usage, those batteries last about 6 to 12 months. That is decent, but you have to replace them eventually. Some models also have a power adapter option, but it is sold separately.
Smarter uses a rechargeable lithium ion battery. You charge it via USB cable, which is more convenient in the long run. A full charge lasts about 3 months with normal use. The downside is that when the battery dies, you cannot use the sensor until it is recharged. You can still open the lid manually, but that defeats the purpose. Also, if you forget to charge it, you might be stuck waving your hand at a dead bin.
Simplehuman offers a wide range of sizes, from 30 liters to 58 liters. The most popular size for families is the 45 liter model, which fits standard kitchen trash bags. The square shape fits nicely into corners and cabinets. The lid has a plastic inner rim that holds the bag in place, so no unsightly bag overhang.
Smarter only comes in a 45 liter size, which is good for most kitchens. But it is round, which wastes corner space. Also, the bag installation is a bit fiddly. you have to stretch the bag over the rim, and if you use a cheap bag, it might slip. Simplehuman’s bag cinch system is foolproof. If you have specific space constraints, Simplehuman’s variety gives you more options.
Smarter is the true smart bin. It connects to Wi Fi and works with Alexa and Google Assistant. You can also use the Smarter app to set a schedule, like having the lid open automatically at 8 PM for trash night. The app sends notifications when the bin is full, based on usage time, but it does not actually measure the trash level. That is a gimmick, but some people like it.
Simplehuman has a few “smart” features too. Their higher end models have a sensor that counts how many times the lid opens, and they have a companion app that suggests when to take out the trash. But no Wi Fi, no voice control. It is more of a fancy sensor bin than a connected device. If you love smart home integration, Smarter is the winner. If you just want a reliable can that works without apps, Simplehuman is simpler.
Trash cans get dirty. Simplehuman’s inner bucket is removable, and the lid can be lifted off entirely. The stainless steel surface wipes clean with a damp cloth. The fingerprint resistant coating is a lifesaver.
Smarter also has a removable bucket, but the plastic exterior is more prone to scuffs. The lid has a rubber gasket that can collect grime. You can wipe it, but it is not as easy to deep clean. Also, because Smarter has electronics, you cannot submerge the lid in water. Simplehuman’s lid is also electronic, so same caution, but at least the body is easier to maintain.
Simplehuman sensor cans are positioned in the premium segment, while Smarter is a budget friendly option. That is a significant difference. You are paying for Simplehuman’s build quality and brand reputation. Smarter gives you smart features at a lower price, but you sacrifice durability.
Consider your usage: if you are a renter who moves often, Smarter might be fine. If you want a can that lasts 10 years, Simplehuman is the safer investment. Also, check the buying guide at best trash cans for more options.
Yes, both use standard kitchen trash bags, but Simplehuman’s rim system holds the bag better. Smarter requires you to stretch the bag over the top, which might slip if the bag is too small or cheap.
Simplehuman has a patented slow close lid that rarely slams. Smarter’s lid closes with a spring mechanism that can be loud and bang shut if you push the lid down. In a quiet kitchen, Simplehuman is more pleasant.
No. Both work as basic sensor bins without Wi Fi. Wi Fi only gives you extra smart features like voice control and app notifications on Smarter. Simplehuman does not need Wi Fi at all.
In the end, the best smart trash can for you is the one that fits your lifestyle. If you are a tech enthusiast who loves voice commands and can tolerate a less premium build, go with Smarter. If you value reliability, quiet operation, and a can that will look good for years, spend a little more on Simplehuman. Both are solid choices, but they serve different needs.
