I don't have the Allergy one, but the one for hardwood floors, which has an attachment with only a brush in the front so it doesn't scratch the floors. Personally, I prefer this one even though I have tiles because the vacuum cleaner sucks so much that I struggle to lift it off the floor with the larger attachment (the one that automatically adjusts the height according to the type of floor/rug).

The other attachments are also very useful, both for furniture, corners, hard-to-reach areas, and also for the computer box given the suction power.

For my 60 square meters, I believe I should have gotten the stick one, although the cord is long enough that I plug it somewhere in the middle of the apartment and I can vacuum the entire house.

I have never seen a vacuum cleaner change the color of my carpets before. The vacuum cleaner sucks up even the tiniest dust particles while recycling the air through 18 HEPA filters. My previous vacuum cleaners left a recycled dust smell, but this one cleans the air. In my 56 square meter house, my hand doesn't hurt because it is relatively heavy. If I had to clean more, I would complain more. Additionally, the price is a negative if it lasts less than 10 years, considering I have only had it for 1.5 months. I have vacuumed 7 times and haven't emptied the bin yet. The assembly took me 10 minutes, the instructions were insufficient, but it's not rocket science. I highly recommend it.
