In addition to a vacuum cleaner robot, I also have a battery-operated vacuum cleaner on hand when I do housework. There are dime a dozen, for example from eufy, from Jimmy or from Dreame and Tineco. The latter manufacturer presented a new series with the Tineco Pure One S15; Caschy had tested the predecessor S12. There are three different ones: S15 Essentials, S15 PET and S15 Pro. The S15 Essentials is the base model. The scope of delivery already includes a free-standing charging station, the crevice tool and the 2-in-1 dusting brush. The S15 PET also has the mini power brush and an app connection. The Pro model also comes with an LC display, which provides insight into the status of the cordless vacuum cleaner. I’ve got the full-featured Pro model in front of me, although I can anticipate at this point: the slimmed-down versions would certainly do the same. 
Tineco specifies a suction power of 29,000 Pascals for the S15 Pro. The dust container has a capacity of almost half a liter. The battery is built-in – just like the predecessor – 2,500 mAh, which – depending on the cleaning mode of course – should last up to 40 minutes. A second battery is no longer included in the scope of delivery. Of course, the volume also varies. Tineco specifies a maximum of 80 dB(A). You can manually switch between 6 levels, but the vacuum cleaner can also be set to maximum mode (level 6) and an automatic mode. In automatic mode, the vacuum cleaner is based on the degree of contamination of the surface.
When the carrier brought the S15 Pro, I was surprised by the compact size of the package. If you take the S15 apart into its separate parts, it takes up little space despite the included accessories. The vacuum cleaner weighs almost 3 kilograms.
Tineco offers another app for the cordless vacuum cleaner. One may wonder what the use is. The vacuum cleaner communicates with the app via WiFi, so you don’t have to connect with a Bluetooth connection every time, adding it once to the network during setup is enough. An account is also required to use the app. Then details the condition of the filter and battery capacity.
I’d say the information about the new display is enough – and you don’t have to pick up your smartphone first. For statistics enthusiasts, there is also a cleaning report. At least in the Pro model, Tineco has installed a new display. In normal use, in addition to the battery status, the display also shows the current cleaning mode and the suction power. In addition, whether a Wi-Fi connection is available and whether the voice output is active. There should definitely be a place here for a display of the filtering performance – then the app would be almost redundant. A colored ring on the edge indicates the degree of soiling.
When switched on, the vacuum cleaner is immediately in automatic mode. The button on the handle allows you to switch between maximum mode, automatic mode and manual mode. As with the previous model, the unpressurized, capacitive slider gives you the ability to vary the suction power – or navigate through the settings.
The “trigger” is only used as an on/off switch. So nothing has to be pressed, the vacuum cleaner remains switched on until you press it again. By the way, it only communicates with the app when it’s turned on – so it’s not permanently connected to Wi-Fi and eats up the battery. Fortunately, the speech output can be switched off with a little searching in the settings and practical navigation via the display.
I already mentioned it: there is no removable battery, but there is a new charging station. It stands free-standing and is connected to the power supply with the socket. Practical, because you can quickly change position and you do not drill anywhere in a rented apartment. The base station holds the vacuum cleaner without any problems, so you don’t have to worry about anything falling over.
Even visually, the Tineco doesn’t pull as many looks as the brightly colored competition at Dyson. In addition, the replacement nozzles can be cleverly stored at the base station. The battery is replaceable, but cannot be charged outside the vacuum cleaner. That would certainly be practical for people buying another battery. At least that shouldn’t be a problem in terms of longevity and the battery can be replaced separately. During the charging process, the display shows the charge percentage in the correct direction – so it’s not just the LED on the battery that lights up.
The handpiece of the Tineco makes up almost 1.8 kilograms of the total weight of 3 kilograms. This doesn’t exactly make it the lightest handheld vacuum, but it’s flexibly adjustable. Since you don’t have to keep your fingers on the trigger all the time, the weight of the cordless vacuum is okay, although the handpiece can probably support a slightly smaller proportion of the total weight.
I was always pleased with the cleaning performance of the S15 Pro. The suction power does not have to hide for competing models and the automatic mode is also switched in dusty places, although Level 2 and Level 3 often didn’t seem like much to me. The automatic mode did not really bring the vacuum to full speed for me. Apparently the vacuum robot is also doing well so my dirt couldn’t challenge the Tineco S15 Pro anymore.
The different suction nozzles make it easy to adjust the cordless vacuum cleaner. What I like here is the regular brush, which, as promised, ensured that few hairs got tangled. So if there are male, female, different or even animal creatures with long hair in your household, this should be a real breath of fresh air.
At full speed, the battery is empty within 10 minutes – when the battery is lukewarm. Thanks to the automatic mode, you don’t have to fiddle with it manually or give it full throttle. Practical when vacuuming under furniture: thanks to the joint on the brush, the cordless vacuum cleaner can rest almost vertically on the floor. The LED lighting at the bottom is also useful here if you want to see the cleaning result yourself and do not fully trust the automatic mode.
As with the vacuum robots, the corners are the most problematic, so the nozzle needs to be replaced. In automatic mode, I had no problems vacuuming the entire apartment. Extrapolated, the specified 30 to 40 minutes comes out. Unfortunately, the teat is not full as quickly as it is empty. The charging process takes three to four hours. It would therefore have been very practical to charge an optionally available second battery outside the device and simply place it in the device instead of charging it. I dare not judge what the loss of suction power will look like in the long term – but even with a full dust container, nothing was noticeable. In the long run, however, the Anker model used here earlier did.
After cleaning is before cleaning. And the dust container, which holds almost 500 milliliters, needs to be emptied every now and then. Handy was a lever that opens the lid of the dust container for emptying. This pushes the collected dirt down so that no tufts of hair get stuck. I can’t say much about the filter performance, except that my house dust allergy didn’t bother me when vacuuming – so the HEPA filter does a decent job. Practical story: The filter is easy to replace and rinse. And: A valve prevents dirt from sliding back into the vacuum cleaner tube.
Some kind of conclusion? cost point for the S15Pro? 599 euros. The essentials variant and PET edition cost 399 and 499 euros respectively. Compared to last year’s model, the new base station is a welcome innovation. The display is also a welcome improvement – does that really justify such a price premium? Hardly likely.
Otherwise a very flexible cordless and hand-held vacuum cleaner model, which has never let me down in everyday life and has delivered a decent cleaning result. As for the suction power, the “Non-Pro model” for 200 euros less will suffice.
