The QV 35A is an upgrade over the Qrevo S (that's what Roborock states). Both have the same mopping system, cleaning mechanics, and a self-cleaning station.
Roborock mopping:
- Features dual mops
- Lifts the mops on the carpets
- Washes and dries the mops on the station
The multi-functional dock does the things:
- self-emptying
- water tank auto-fill
- washing and drying the mopping pads
- has a detachable base
The two models have the same self-cleaning station; however, the Qrevo S station dries the pads with hot air, while the QV 35A uses cool air.
Qrevo S is the basic Qrevo modification
The upgrades over the QV 35A:
- Hot air pads drying
The Qrevo S is a better mop thanks to its hot air drying feature. The mops don't stink after cleaning and are ready for the next cycle. This feature also reduces the number of times you have to wash the pads manually.
The Qrevo S is a better mop
Upgraded Qrevo S, the QV 35A
The upgrades over the S:
- Stronger suction
- Newer side brush
The robot is a better buy for carpets, or if you don't need mopping as much.
A better option for pet owners and homes with carpeted surface
What to buy
The Qrevo S is if you need a better mopping feature.
The QV 35A for vacuuming performance.
