I LOVE getting new toys. This one was sent to me in January 2020 by Banggood and it turned up in the UK in February. The battery-powered, USB-charged Zajia clips straight into the tap in the kitchen or bathroom to provide proximity-controlled water. If you are on a water meter or just environmentally-conscious – this device might just be for you.
As you can probably tell in this article generally, back in February the health positive implications of this device had not really occurred to me – but in May 2020 in the middle of the pandemic, it seems absolutely sensible, even essential, on returning home after shopping, NOT to touch ANYTHING in the house BEFORE washing hands. All I need now is an automatic soap dispenser to go with the Zajia which, incidentally is STILL on it’s first charge.
The Xiaomi Zajia comes with a range of (plastic so no rusting) tap adaptors and takes seconds to slip onto the bottom of any mixer tap. I don’t bother to turn off the tap as the device has zero leaks, instead, I just leave the tap mixer set to the kind of temperature I usually need for handwashing etc.
The Zajia has proximity sensing on the underside for a short burst of water as required and another on the back (or front as you prefer) for constant ON or OFF. Just put your hand, toothbrush, razor or whatever underneath the Zajia and out comes the water. It’s all very intuitive – so that I could not tell you if it came with instructions or not – certainly didn’t need any.
When the device arrived last week I lifted the grey flap and plugged in a USB supply to give it an hour’s charge – and that’s it, the device has been in constant use ever since. Now that I’m used to it, I hate using taps that don’t have similar devices. I fitted this in the kitchen to test initially and then into the smaller of our two bathrooms – the only thing wrong is that I now need two more for life to be complete again. The Zajia doesn’t seem to get in the way and doesn’t get dirty as of course you don’t actually touch it. Needless to say it is waterproof.
If I were to improve the device I’d add a temperature sensor and third proximity sensor to somehow detect how hot or cold I wanted the water to be – but I guess that’s stretching things a little.
