Replace wireless vacuum cleaner battery

I've been using the wireless vacuum cleaner that I bought when I first lived alone.
It's a plus-minus zero Y010 product, and it's a home appliance that I love because it's so pretty, light, and has good performance.
Recently, my battery ran out quickly, so I thought I should buy a new vacuum cleaner.
But when I searched it, I found that only the battery can be replaced!
There were a lot of companies in Naver's smart store
I chose a place where the main body and head cleaning services are also available.
smartstore.nav...
I was very satisfied because I was able to buy a battery replacement, cleaning, and dust filter for less than the original battery cost (99,000 won)! (It's my money ^^)
Not only vacuum cleaners but also other home appliances have battery replacement services, so it would be good to refer to them.
