ᐅ How does an electric door release work?

Hello
The IKEA online planner shows me an option for an electric push-to-open mechanism for the FA170 (base cabinet for sink with drawer), Utrusta item number 702.272.36.
Could someone please explain to me exactly how it works?
I am not entirely clear on it even after reading the installation manual.
Best regards

Do you mean during installation or in general?

Important product features
- The recycling bin can be opened with a push of a finger or by bumping it with your hip, knee, or foot; very convenient when your hands are full.

The question is whether it’s really worth spending that much money on something like this...

Are you referring to the installation or in general?

I mean in general!?!
What happens if I tap the drawer? Will it open by itself then???
I’ve already looked for a video, but there doesn’t seem to be anything...

And the installation instructions are not clear to me either.
I assume I need an electrical outlet near the cabinet, but where is the "sensor" or whatever it is supposed to be placed?

Yes, you of course need a power outlet somewhere nearby, since the device is electric...

From the installation manual, I gathered the following:
There is no separate "sensor"; everything is already built into the opener.
So, when you press against the front, the drawer opens a few centimeters (pushed forward).
What this is supposed to achieve is unclear to me, since you still have to open the drawer fully by hand...

But I find it somewhat amusing that it is automatically included in the kitchen planner.
They probably figure that with a kitchen costing several thousand euros, an extra 100 euros won’t really be noticed...

Best regards

Thanks for the reply.
Could it be that the drawer fully extends after tapping it? That would make more sense.
However, even then, I would still need one hand free to open the lid of the waste container.
Does Ikea actually offer a solution, like other kitchens, where the lid of the waste bin opens automatically when the drawer or door is opened?
Does anyone in the forum have this electric push-to-open mechanism and can share more details about it?
Otherwise, on my next Ikea visit, I will ask where it is installed in the showroom and record a video of it.
