How to fine tune product details on Google Shopping search

I have a very specific need.

A front-load washing machine of maximum 83cm tall.

But the ranges I see in google shopping are like the following:

I need to specify very well the range for a characteristic of the products.

Process:

1. Click on one of those options with a range and get the URL

https://www.google.com/search?tbm=shop&sxsrf=AL9754&q=lavadora++frontal&tbs=vw:l,mr:1,pdtr0:70722|7073,cat:2549,pdtr1:10093|80.0%2483.0&sa=X&ved=0ahUKEwjs1ss7_uAhNxoS-AH0QvSsoAQ&biw=18&bih=929  (note: this url will not work, I removed lots of stuff for clarity purposes).

2. Inspect it and look for the 2 numbers of your range. In the URL above are 80 and 83

80.0%2483.0&sa=

3. Replace them for whatever you want  (80 and 83 in my case) and paste the URL

4. Voila! Now you have the exact range you were looking for.

Now... We have setup the range on the left pane.

However the results ... may or may not respect that.

And some results say something (82cm) and if you go to the page of the manufacturer it shows 84.8cm

Well.... It's Internet. Don't believe everything/anything you see.

I hope it helps.
