Royal Bin® vs simplehuman
Royal Bin® vs simplehuman: Which Smart Trash Can Actually Seals the Bag?
simplehuman makes some of the most popular sensor trash cans in the world. Trash King® makes the Royal Bin®, a self-sealing smart trash can. They solve the same chore two different ways, and the difference shows up at the exact moment the bag gets full. This page compares the Royal Bin® 17L with simplehuman's sensor cans using only facts published on each maker's official store, checked on October 10, 2026.
The short answer
A simplehuman sensor can opens when you wave or speak, and that is where the automation ends: when the bag is full, you pull it out, tie it, and fit the next liner by hand. The Royal Bin® 17L opens with a wave or a tap, and when the bag is full it heat-seals the bag shut, drops it, and reloads a fresh bag automatically. If you want a large can that opens hands-free, simplehuman is built for that. If you want the bag handled for you, that is the job Royal Bin® was designed to do.

simplehuman's smaller sensor model, the 45L Semi-Round Sensor Can, costs $150 to $160, opens by motion only, runs on AA batteries, uses Code J liners, and carries the same 5-year warranty. It also does not seal or reload bags.
What happens when the bag is full
This is the honest dividing line between the two brands. With a simplehuman can, a full bag is your job: open the rim, pull the liner out, tie it, carry it, then pull a fresh liner from the storage pocket and fit it by hand. Their official copy describes the rim as a way "to keep the liner tidy and out of sight," which is exactly what it does. It hides the bag. It does not close it.
With the Royal Bin® 17L, one tap starts the full cycle: sealing bars clamp the bag and heat-seal it shut, the sealed bag drops, you lift it out with clean hands, and a fresh bag reloads itself from the SmartRing™ refill inside the bin. No tying. No mess. No second thought.
What each one costs to own
The cans: $199 for the Royal Bin® 17L, against $300 to $325 for simplehuman's 58L sensor can and $150 to $160 for its 45L semi-round. The bags: a SmartRing™ ring holds up to 25 bags and costs $12.60 on its own, or $7 per ring in the 6-pack, which works out to as low as $0.28 per bag. simplehuman's Code Q liners for the 58L can cost $32 for 100 (about $0.32 per liner). Both systems use bags made for the can; the running costs are in the same range, and the difference is who changes them.
Which one fits you
Choose simplehuman if capacity is the priority: at 45L and 58L, their sensor cans are much larger, the 58L adds voice control and a dual-compartment recycler version, and the brushed steel look suits a big kitchen. Choose the Royal Bin® 17L if the point of a smart can, for you, is never touching the trash: sealing, dropping, and reloading happen for you, the 17L size fits standard spaces, bedrooms, and offices, and every bin is covered by a lifetime warranty. For a large kitchen, Trash King® also makes the Royal Bin® Ultra 30L at $349.
