So there are main 5 differences:
- base station configuration
- mapping system
- pad-washing module
- front obstacle avoidance sensor
- price
The Q Revo will rearrange the layout of its base station moving the bag to the middle underneath the water tanks.
1. The base station configuration.
While the S8 Pro Ultra uses the same configuration as the S7 MaxV Ultra with the water tanks and bag in one row.
2. The mapping system.
The Q Revo with the first robber up with two spinning discs similar to other brands like Ecovacs. The S8 Pro uses one pad with two vibrating elements for agitation.
Roborock S8 Pro Ultra
A self-cleaning, auto-emptying docking station places it a few notches above other robot vacuums, ensuring a mostly hands-off cleaning experience.
$1599.99 on Amazon3. A pad-washing module.
The key level design is simpler by using a tray with these studs where the pads spin against and agitate.
The S8 Pro releases on the bristle brush component that slides back and forth the scrub off debris from the pad.
And maybe the Q Revo version is better since it's a one-piece plastic component that doesn't wear out easily compared to the bristle brush of the S8 Pro. That's prone to wear.
4. is the front obstacle avoidance sensor.
The Q Revo only has the front IR sensor while the S8 Pro Ultra has the IR sensor and two lasers flanking.

Based on internal testing carried out by the manufacturer, the mops can be lifted up to 7mm.
$899.99 on Amazon5. The price.
So our last point is the price and it is worth noting that the difference in price is pretty decent. Therefore, if this matters to you when choosing a device, then you should pay attention to this.
