Tineco Pure One A50S cordless vacuum review: superb suction but a flawed design

Tineco Pure One A50S: two-minute review

While it certainly has a few foibles, the Tineco Pure One A50S cordless stick vacuum offers a decent combination of features and performance. I tried out the 'Plus' version, which comes with an extra detail tool, and while I wouldn't count it amongst the best cordless vacuums I've reviewed, it does come with some appealing features.

Its 60-degree or so swiveling floorhead and bendable wand make it easy to maneuver around furniture and under beds. The suction power is very impressive, too, effectively picking up dust, debris and even pet hair from various floor types. That said, I wouldn't recommend this model solely for dealing with pet hair because its floorhead feels very resistant on carpet and is therefore tiring to push and pull.

On the other hand, the smart DustSense sensor, which automatically adjusts suction power based on the amount of dirt detected, is genuinely useful and certainly contributes to more efficient cleaning. Battery life is reasonable, too, though larger homes might require a recharge for a thorough clean; and it has a larger bin than the norm which in turn reduces the need to empty it too often. However, while it performs very well at sucking stuff up, the A50S is let down by poor ergonomics and a few other niggling design details.

That's the short version; read on for my full Tineco Pure One A50S Plus review.

Tineco Pure One A50S review: price & availability

• List price: $329 / £329
• Launched: Fall 2024

The Tineco Pure One A50S has a list price of $329 / £329, which puts it in the mid-range price bracket for cordless vacuums. It's available to buy direct from Tineco, or via Amazon.

It's competitively priced when compared to other mid-priced cordless vacuums with similar features. However, there's some very strong competition out there, most notably the Dreame R20 which, while equipped with a smaller bin, is lighter in the hand and therefore easier to use.

If you're smart about when you buy, you might be able to avoid paying list price too. At time of writing the UK version was discounted to £229 on the Tineco site, for example. The Black Friday sales tend to be an especially good time to shop for new appliances.

Tineco Pure One A50S review: design

• Forward-bending wand for cleaning under beds
• Handle a little awkward and uncomfortable to hold
• No instruction manual included

Tineco – a sub brand of Ecovacs the robot vac company – has been producing innovative cordless vacs, wet and dry mops and carpet cleaners since 1998. The Chinese company is perhaps best known for the high level of 'smarts' it injects into the majority of its products. Chief amongst these is the interface, which invariably involves a (sometimes quite huge) colorful onboard LCD monitor that provides the user with all manner of information, often using animation for added pizzazz. Tech nerds (me included) love this kind of stuff, though I wouldn't say any of it makes Tineco's machines any easier or more efficient to use.

However, while other models like the Tineco Pure One S15 Pro and PURE One S11 come with huge, colorful circular displays at the head of the hand unit, this model opts for a much smaller and less fancy info monitor that provides little more than three vacuum modes – Eco, Auto and Max – plus a couple of tiny icons that light up if the air channel is blocked or the brushroll is tangled. There's also a simple three-bar battery level indicator. Oh, and you thankfully don't get a trigger with this model – instead you tap a simple on/off button on the rear.

Elaborating on these power modes a little more, the A50S Plus uses a feature called DustSense that automatically adjusts the suction draw depending on the amount of muck it detects. Many modern stick vacs have this feature and it provides a good balance between cleaning efficiency and battery use. However, I find the 'Auto' power band description a bit confusing because from what I've noticed, both Eco and Auto use the DustSense function whenever the floorhead sensor detects some extra detritus. And you can hear the change in motor pitch as the power is increased, usually for just a few seconds.

From what I can gather, the Eco mode ramps the power up to the equivalent of Auto mode, and Auto mode increases its power to the equivalent of Max mode which doesn't use DustSense at all because it's already at maximum power. You still with me? This means that 'Auto' is actually a false flag and more like a medium mode. Not sure why Tineco's designers opted for this labelling but I'm guessing they called the equivalent of a medium mode 'Auto' for marketing reasons because, well, everyone uses auto mode on every device, right?

According to Tineco, the Pure One A50S Plus boasts 185 Watts of suction power which is rather confusing since most manufacturers use either Air Watts or Pascals when measuring their products' statistics (here's more on how to tell how much suction your vacuum has). All I know is that there is no shortage of suction power here, as I'll get into in more detail in the Performance section.

Let's take a quick tour of the Pure One A50S Plus' handle design, starting with its ergonomics. The A50S Plus's handle is comprised of two grip sections, and your hand naturally gravitates to the rear handle because that's the area with the small protruding finger support. Also, this is the type of hand position that most stick vac manufacturers opt for.

However, I've found that if you use the rear section of the handle, the angular edge of the info screen mount digs into the flesh between thumb and index finger and rests on a pressure point that hurts after just a few minutes of use (Dyson's vacs have a similar effect). But worse than that, this position also involves bending the arm at the elbow which means your biceps and anterior muscles in the forearm end up holding all the weight, while the shoulder muscles take care of the pushing and pulling.

Call me a loafer but I want an easier ride when doing one of the most mundane tasks in the home, so I tend to vacuum with a completely straight arm while performing a pendulum motion using mostly the top of my biceps and shoulder muscle group. I simply walk slowly forward while swinging the whole unit back and forth like a grandfather clock's pendulum. You should try it.

However, if the handle on the vac is positioned in a way that involves bending the wrist and arm – like this and most other models – I immediately ask myself why manufacturers continue to insist on making models with right-angled handles on the rear when they should ideally be positioned above, and be smooth and circular in shape. Roidmi with its rounded rectangular handle on the X30 Pro, Miele's Duoflex models and Vax with its Blade series have managed it, so why has no one else cottoned on?

But I digress, because, as alluded to above, the Tineco A50S Plus does indeed have a second grip section at the top, though it's still not especially comfortable to use because the pinky finger is squashed in the process. It's not terrible but it's not brilliant either. Also, this model's weight – 3.3kgs with wand and main floorhead – is higher than other models I've tested – just over half a kilo heavier than the Dreame R20 I very recently reviewed – and that makes it feel heavy in the hand, especially during a long session on the pile.

While most stick vacs ship with a relatively small dust bin of between 0.5 liters and 0.8 liters, this one comes with a substantial one-liter capacity for longer cleaning sessions and fewer trips to the kitchen bin. The emptying mechanism is pretty much the same as all stick vacs, Dyson notwithstanding. In other words you awkwardly unlatch the bin section from the motor housing, and flip a latch to empty the contents. Since this bin is larger than most, clumped pet hair tends to fall out though it might involve a gentle tap of the unit against the inside of the kitchen bin. However, it can be a bit fiddly to fit the bin back onto the vac.

Since the inner mesh filter inside the cyclone section was as dusty as expected, I attempted to pull it out to give it a clean but it wouldn't budge. So I tried twisting it, still to no avail. I then reached for the accompanying manual only to discover that it was full of useless safety and troubleshooting information with absolutely nothing on how to use the machine, let alone remove the mesh filter. So I went online and downloaded the manual from the Tineco website but it was the same piece of safety literature. Needless to say the mesh filter is still firmly attached and perhaps it's designed that way – answers on a postcard please. [Ed's note: we contacted Tineco's PRs, who say the filter can be removed, although we're still not sure exactly how.]

I was, however, able to access the washable sponge HEPA filter system, which works in tandem with said mesh filter to remove '99.9% of dust and debris as small as 0.3μm', one micrometer. This model also includes a scent block that clips under the battery to help keep carpet smells at bay. (This last feature is unusual but not unheard of – it's most associated with today's best Shark vacuums.)

Regarding the business end, this model comes with a sturdy articulating wand that can bend 90-degrees for easy access under beds and sofas, and a 23cm brush bar comprising two rows of chevron-shaped bristles designed for both hard floor and carpet. The roller brush can be easily removed for cleaning.

In general, the build feels clunky, unrefined, and less maneuverable than other vacuums I've tested – not just pricy models like those made by Dyson, but even more budget-friendly options from the likes of Dreame.

According to the blurb, the Tineco's 3DSense brush bar has built-in sensors that will automatically boost suction whenever it detects the edge of a skirting board. In fact you can see two small cutouts on each side of the floorhead's housing, which allow the suction to draw in air from the sides, along with any dust that's lurking along the edges. Nice. There are also two rows of stiff combs at the rear of the brush to prevent entangling of hair and cotton strands.

In order to help the brushroll collect larger particles on hard floor and when using it on carpet to help reduce friction, the floorhead is also equipped with an air intake switch that opens two little ports where the front of the head meets the floor. And, in a nod to the best Dyson vacuums on the market, this model's front headlight is green colored to make dust on hard floors more visible. However, unlike the Dyson, which uses a laser to highlight even the finest of particles, this model uses a simple green LED bulb. Nevertheless, it's still surprisingly effective.

For use in handheld mode, the Tineco also comes packaged with a motorized upholstery brush, a detail nozzle with slide-down brush fitting and a wall mount that holds everything in one place. The rear handle position works just fine with this setup, though the body does feel heavy when held up high. Also, like the majority of cordless stick vacs, this model won't stand up on its own so there will be times during use when you'll just have to prop it up against something while you shift any furniture around.

Tineco Pure One A50S review: performance

• Great suction performance
• Decent running time
• Too much suction resistance on carpet

The first thing you notice when holding the Tineco Pure One A50S Plus for the first time is the 3.3kg weight, which makes it feel a bit clunky when carrying it around – a bit like the equally hefty Dyson gen5detect. Personally, I think much of the weight comes from the wand and its over-engineered centre section where it bends at 90-degrees.

Since this vac only comes with one floorhead, which is designed more towards carpet use, it isn't as smooth sounding on hard floor as most hard floor-specific soft rollers. However, while the A50S has proved to be a very impressive cleaner on carpet (see results below), the design of the floorhead makes it feel very stiff to push on even medium-pile carpet, and that's with the little front air-intake wide open and the power in Auto (i.e. medium) mode.

Moreover, when the DustSense feature kicks in, it produces even more friction between the front of the floorhead and the carpet. Put another way, your arm will feel like it's had a good workout after just five minutes of cleaning, although the aforementioned pendulum action helps in this regard. In hindsight I would opt for vacuuming on carpet in ECO mode, which applies less downward suction to the floor and makes it that little bit easier to push.

The Tineco A50S's floorhead articulates up to about 60-degrees – less than a Dyson or the Dreame R20, but decent enough for easy steering around furnishings. However, it is a bit of a struggle removing the wand to swap over to any of the hand tools. The fit is very firm – which is good – but also tricky to release. Incidentally, while quite heavy to hold up in the air, the handheld side of it using the mini motorized brush head is efficient at doing the stairs, the car, the dog bed and sofas, and so on.

I tested the Tineco A50S's noise level and it's not too shabby. In ECO mode it registered at a pleasant 63dB at shoulder height, 66dB in Auto mode and a not considerably louder 69dB in Max mode.

Suction tests

As well as assessing general usability, I ran a series of suction tests. For my main hard floor vacuum test I scattered 25g of oats, flour, orzo pasta, crushed digestive biscuit and a few Coco Pops and set the unit to Auto mode. The motor started gently before the DustSense sensor ramped up the power as soon as it detected the extra debris.

Impressively, it collected everything – even the large pieces – in one sweep. Weighing the contents of the bin, it collected 24g in all but I'm betting at least 1g of the flour likely remained in the bin and around the mesh filter. And that's a great result in my opinion.

For the carpet test I used the same pre-weighed 25 grams of ingredients and used the same Auto setting with the front air intake open. This test required one back-and-forth sweep to remove the majority of the debris and a few more quick passes to remove any evidence of flour.

Like the hard floor test, I measured the bin's contents but this time it said 26 grams because it had also collected some hidden dust in the carpet. Yes, it did take a lot of effort to push the floorhead on the medium-pile rug I used but, hey, it did the job and did it well.

Tineco Pure One A50S review: battery life

• Lasts around 70 minutes in Eco, 17 minutes in Auto and 10 in Max
• Will automatically drop to Eco mode as battery life runs low
• Recharge takes just over three hours

Tineco states a maximum runtime of 70 minutes, which is up there with the longest you'll find anywhere. However, that figure is always for the lowest powered mode. However, I ran a test in Auto mode on a 50:50 medium-pile carpet and tiled hard floor mix and after seven minutes the battery depleted by two bars (from three). Nevertheless, it carried on running till around 17 minutes before automatically switching to Eco mode where it continued at lower power before coming to a stop at 20 minutes and 22 seconds.

In Max mode, runtimes are understandably shorter. I ran this test on hard floor only, because it's too powerful and creates too much friction on carpet. From full charge, it lasted just shy on 10 minutes in Max, before dropping to Eco where it ran until 12 mins 16 seconds before stopping.

Now I should add that most day-to-day vacuum tasks would likely be just one or two rooms unless doing a full spring clean, so 20 minutes in Auto mode is perfectly acceptable, especially given the the DustSense feature boosts the power and battery usage when it detects extra dirt. However, if you have a weekly cleaner who uses your cleaning tools to vacuum the entire home, this model may struggle to complete a whole three bedroom house with kitchen lounge, dining room and bathrooms on a single charge, especially if used entirely in Auto mode.

Now that the battery was completely flat, I fully recharged it and it took exactly three hours and four minutes, which is about average for a cordless stick vac. By the way, I did notice that the charging bar on the screen turns off after a set amount of time so you will need to press the power button while it's connected to the mains to check its progress. However, there is also a green light on the side that pulsates throughout the charging process so I would use that as a charging state reference.

How I tested the Tineco Pure One A50S

I received the Tineco Pure One A50S Plus a few weeks ago so have had plenty of time to live with it and put it through its daily paces. Despite some annoying traits, it does vacuum well and I do rate the extra large bin. Aside from general vacuuming on both hard wooden flooring and carpets up to medium pile, I also tested it using a variety of ingredients – including some large biscuit crumbs – and it sailed through both floor-type tests. However, my overriding thoughts is that it feels a bit clunky when compared to other stick vacs I've used.
