Roborock S7 MaxV vs Roborock Qrevo

The Roborock S7 MaxV is a little more capable than the Roborock Qrevo, though the Qrevo is a very solid option for the price. The S7 MaxV has a more advanced hazard detection system, which uses an RGB camera as opposed to the structured light sensor found on the Qrevo. Not only does this result in superior object recognition capability, but it also means that you can use the S7 MaxV as a roving security camera when you're away from home. The S7 MaxV also delivers better overall debris-pickup performance. That said, the Qrevo's mopping system can lift higher, so you don't have to worry as much when the vacuum is transitioning from mopping stains to cleaning carpets within the same cleaning cycle.
