Winner (Based on Challenges)

On hard floors the VIOMI A9 and the Roidmi X20 perform the best in my challenges. Taking in account, the Roidmi X20 is more expensive therefore i would pick the VIOMI A9 as winner.
When it comes to carpets only, the Roborock H6 adapts wins as it can clean deeper than All other 3. Even after I used all vacuums on the carpet, the roborock still took off dust hidden deeply inside the carpet! there's a possibility to buy a softroller brush separately!
The Dreame V9 is currently the cheapest of them all and comparing it I think it's the less best. Still worth buying as it eventually picks up everything on the floor in normal conditions. In fact I have use this cordless vacuum from more than a year now! Also check upon newer models from this company as they improve with every version!
