We would choose Qrevo S Pro when heated mop care at the lower checked reference is the main goal. Choose L40 Ultra Gen 2 when its documented extending side brush and mop solve recurring edge-cleaning work. Both already provide automatic pad care and dust emptying. The extra Dreame expenditure should buy a feature you need, not an assumption that Gen 2 means every premium function is included.

What extra work could the Dreame’s extending hardware address?

L40 Ultra Gen 2’s official specification lists extension for both the side brush and the mop. That offers a clear purchase rationale when cabinet edges and corners are the areas you repeatedly finish by hand.

Qrevo S Pro’s checked feature description gives a dual spinning-mop system and an all-rubber main brush. We do not assign an extending-mop feature from another Qrevo model to this package. The useful comparison is the hardware described for these exact robots. If you do not have an edge-cleaning problem, the Dreame’s additional reach is a less compelling reason to spend more.

Do both robots lift and detach their mops?

Both document lifting pads for carpet management. Gen 2 lists 10.5mm; S Pro lists 10 mm. Dreame’s model-specific table marks automatic mop removal as unavailable, so do not confuse its lifting mechanism with a dock that takes pads off for vacuum-only work.

This matters for rugs you want fully separated from wet pads. Dreame explicitly advises avoiding fringe rugs and yoga mats in its carpet guidance. Inspect the actual surfaces and use appropriate cleaning restrictions. Similar lift figures are not permission to ignore pile or to present either robot as guaranteed to cross every rug safely.

Which station chores remain?

Gen 2 documents hot-water pad cleaning, hot-air drying and refilling the robot’s water box. Its FAQ explicitly leaves filling the station’s clean tank and emptying the used-water tank to the owner. S Pro also lists heated pad cleaning, warm-air drying, dust emptying and refilling.

These shared functions explain why both are worthwhile wash-station candidates. They also show why a station needs convenient access. Gen 2’s automatic solution-adding configuration is marked separately purchased; do not add that benefit to the base comparison price. A connected station may remove pad washing while leaving water handling and other supplies in the weekly routine.

What should the checked prices decide?

The US references are $499.99 for Gen 2 and $429.99 for S Pro. These manufacturer snapshots cover the named hardware, without guessing tax treatment or adding an accessory configuration.

At those references, we would favor S Pro for a first buyer who primarily wants washing and drying handled by the dock. Gen 2 is more persuasive when both extending implements address the home’s floor edges. For owners, remember that a switch costs another complete system: the price gap between two new products is not the upgrade bill from hardware you already own.

Which prices are being compared?

These are separate listed hardware reference prices from Dreame US store and Roborock US store. The displayed difference is not a delivered checkout saving; tax, shipping, promotions and package details can differ.
