I will no longer consider this company for purchase, it is better to overpay a little more and buy a decent device. Although honestly, this vacuum cleaner cost 20,000, not cheap.
Pros
I liked the rich equipment and double brush.
Cons
The vacuum cleaner broke after 1 year and one month of operation, i.е. The warranty ended and the vacuum cleaner broke. I press the button and the vacuum cleaner does not turn on. I wrote to the seller and in support of redroad they answered that it was not a warranty case, bring it to the service.
