TOWNEW S2000 review

The S2000 is the best-built thing in a small category and the only one whose maker will put real numbers on paper. Sensor lid, a thermal head that welds the liner shut on command, a ring that feeds the next bag into place, and a published spec sheet: 16.0 liters, 305 x 260 x 390 mm, a 2000 mAh cell TOWNEW rates at up to 20 days of standby. Buy it for a bathroom, a nursery or a sickroom, where a bag sealed before it crosses the house is worth real money. Do not buy it as a kitchen can, and do not buy it before you have worked out what the rings cost you per year.

If you have not settled on the category yet, the best smart trash cans ranks this against the five alternatives and explains why none of them connect to an app. This page is for the reader who has decided they want a self-sealing can and wants to know what owning this one is like.

The mechanism is worth describing precisely, because "smart trash can" covers two different products and only one of them is this.

1. The lid opens on a motion sensor, the same infrared arrangement as any touchless can.
2. The liner is not a bag. It is a ring of continuous polyethylene film - TOWNEW calls the S2000's an R16 ring - seated in the top of the can and fed downward as it is used.
3. When the can is full you press the seal button. A heated bar - TOWNEW's "flexible thermal sealing head", which it says adapts to bag thickness and pressure - closes across the film and welds it shut.
4. You lift out a sealed parcel, and the head welds the film again below the cut so a fresh liner is already open and waiting.
5. You never knot a bag, and you never fit a new one. That is the entire value proposition, and it does deliver it.

In the box: the unit, one R16 ring pre-installed, a charging cable and a manual. No wall adapter, which is standard for this class and worth knowing if you do not have a spare USB brick.

This is the first of the two things the listing will not tell you, and it is the one most likely to disappoint somebody.

The Amazon listing title for the S2000 says 5.5 gallons. TOWNEW's own specification page for the same model says 16.0 liters. Sixteen liters is 4.2 US gallons. That is a gap of about a third, and it is not a rounding error. We checked the same brand's T Air Lite as a control: TOWNEW specifies it at 16.6 liters and sells it as 4.4 gallons, which converts correctly. So this is one listing out of step with the spec sheet rather than a company that cannot do arithmetic.

The footprint is genuinely compact for what it is: 305 mm wide, 260 mm deep, 390 mm tall, which is 12.0 by 10.2 by 15.4 inches. That is a can that fits beside a toilet or under a desk, and the dimensions are published, which is more than most of this category manages. Measure the lid swing above it as well - a sensor lid needs clearance it does not advertise.

This is the second thing, and it is the one that should decide your purchase. The S2000 does not take trash bags. It takes R16 refill rings, sold by TOWNEW in three-packs and eight-packs, and there is no supermarket substitute.

Here is the honest complication: TOWNEW publishes a bags-per-ring figure for its T1-series ring - up to 150 bags from a six-pack, which it calls about six months - but we could not find an equivalent published figure for the R16 ring used by the S2000. So you cannot calculate a cost per bag from the box. You have to buy a pack, use it, and find out. We are not going to estimate a number we cannot verify.

What we can say with confidence is the direction. On pure cost per liner, a self-sealing can loses to a box of 8-gallon drawstring bags by a wide margin, and that is true of every brand in this category, not just this one. If you are hoping the convenience pays for itself, it does not. The case for the S2000 has to be made on what the sealing does for you, not on what it saves.

• Buy rings with the can. It ships with exactly one ring installed. The eight-pack is the sensible standing order.
• Do not buy the wrong ring. The R16 fits the S2000 and its variants. TOWNEW's T1-series ring - the one with the published 150-bag figure - does not fit this can, and no Airdeer ring fits either.
• Third-party rings exist at well under half the official price. Fit is reported rather than guaranteed, and a ring that does not seat correctly will jam a sealing head, so the saving carries a real risk on this particular part.
• Measure your own consumption for a month before you commit to a bulk order. A bathroom bin and an office bin burn film at completely different rates.

TOWNEW rates the S2000's 2000 mAh cell at up to 20 days of standby. That is a manufacturer figure on their own testing, and it is worth reading as a ceiling rather than an average - a can in a busy bathroom is not on standby, it is cycling a sensor and firing a heating element.

Two practical notes. First, a heated sealing bar is a far bigger draw than an infrared lid motor, so this will want charging considerably more often than a battery-powered sensor can wants new cells. Plan for a cable within reach. Second - and this is the structural weakness of the whole category - the battery is not user-replaceable and TOWNEW does not sell it as a part. A rechargeable cell has a finite number of cycles in it, which makes this a five-year appliance rather than a ten-year can.

Interestingly the cheaper T Air Lite is rated longer, at up to 30 days standby, which is what you would expect from a simpler mechanism with a push-button seal instead of a sensor lid. If battery anxiety is your main worry, that is the model to look at. For battery behavior generally across sensor cans, touchless trash can batteries and power covers the ground.

We are skeptical about a lot of this category, so it is worth being equally clear about where this can is the right answer rather than an indulgence.

• A bathroom. A bag welded shut before it leaves the room is the single best argument for the product, and it is the one the marketing underplays in favor of the word "smart".
• A nursery. Compared fairly - against a diaper pail with a proprietary cassette rather than against a box of bags - the running cost looks much more reasonable, and the sealing is at least as good.
• A sickroom, or a household where handling waste is physically difficult. Not having to gather, knot and lift a liner is an accessibility feature. This is the use we would defend hardest, and it is the one nobody markets.
• A small office or a studio flat where the bin shares a room with you and the walk to a dumpster is long.

And the uses we would talk you out of: a family kitchen, because 16 liters will not keep up and the per-liner cost at that volume is punishing; a garage or utility room, because nothing there needs sealing and a plain can is tougher; and buying it to fix a smell, because a sealed bag does nothing about the bucket underneath it. That is a cleaning problem, and it is free to fix.

If the attraction is hands-free and the sealing is incidental, buy an ordinary sensor can - you will get far more capacity for less money and you will not be on a film subscription. The best touchless trash cans ranks that field. If the attraction is the sealing but the price is not, the TOWNEW T Air Lite does the same weld with a push button instead of a sensor, at a published 16.6 liters and a longer battery rating. And if you need this at genuine kitchen capacity, the only option is the Airdeer L2 at a listed 8 gallons - with the caveat that Airdeer publishes no spec sheet at all, which after reading this page you will understand why we weigh heavily.

The can and the consumable it needs. Buy them together - the S2000 ships with exactly one ring installed.

The comparison we would most want you to make before ordering: price a year of R16 rings against a year of 8-gallon drawstring liners, look at the difference, and decide whether a sealed bag is worth that to you. For a nursery or a sickroom the answer is often yes. For a spare bathroom it is usually no, and there is no shame in that.
