Roborock F25 RT Gen 2: Specs, Runtime & Differences

Updated 1 October 2026. Roborock’s F25 Gen 2 family is a wet-and-dry floor-cleaning range aimed at homes that want one machine to vacuum loose debris and wash hard floors in the same pass. In South Africa, the Roborock F25 RT Gen 2 is the clearest locally documented Gen 2 model, so this guide focuses on that version rather than mixing specifications from every F25 variant.

That model distinction matters. Roborock sells several F25 configurations globally, and battery life, sensors, displays and self-cleaning features vary between them. A specification that applies to the F25 Gen 2 or F25 LT Gen 2 should not automatically be treated as an F25 RT Gen 2 feature.

Roborock F25 RT Gen 2 specifications

• 20,000 Pa claimed suction power.
• 450 RPM roller cleaning frequency.
• 20 N downward cleaning pressure.
• Less than 1 mm edge-cleaning gap under Roborock’s test conditions.
• Up to 38 minutes of Eco Mode runtime for the RT Gen 2.
• Claimed cleaning coverage of up to 284 m² per charge in Roborock testing.
• 870 ml clean-water tank and 720 ml dirty-water tank.
• Approximate machine weight of 4.2 kg for the RT Gen 2.

Roborock publishes these figures on its South African F25 RT Gen 2 page and global model comparison. They are manufacturer figures, not Technology Blog laboratory measurements, and real runtime or cleaning area will vary with floor type, cleaning mode and dirt load.

Roborock F25 RT Gen 2 vs Gen 1: what changed?

The easiest measurable difference is not simply suction. Roborock’s earlier F25 RT was already rated at 20,000 Pa on the company’s support material. The Gen 2 model is better understood as a refinement of the platform rather than a straightforward suction-power upgrade.

The older F25 RT global specification listed about 40 minutes of Eco Mode runtime, while the F25 RT Gen 2 is listed at up to 38 minutes. That means buyers should not assume that a newer generation always means longer battery life. The Gen 2 changes instead centre on the updated cleaning head, FlatReach 2.0 positioning, edge cleaning, anti-tangle design and revised chassis.

FlatReach 2.0 and cleaning under furniture

Roborock positions FlatReach 2.0 as a way to lower the cleaner for access under furniture while maintaining cleaning performance. For homes with low sofas, cabinets or beds, that can matter more in practice than another headline suction number.

The practical limitation is still physical clearance. Owners should measure the gap under furniture rather than assuming every low space is reachable. A wet-and-dry upright also needs room for the handle and user movement; it is not a robot vacuum that can disappear under furniture by itself.

JawScrapers and hair management

The RT Gen 2 uses Roborock’s JawScrapers anti-tangle design, combining a scraper against the roller with comb-like elements intended to reduce hair wrapping. Roborock advertises a zero-tangle result under its own tests. That should be treated as a manufacturer test claim rather than a guarantee for every household, particularly where long hair, pet hair and fibrous debris are mixed.

Self-cleaning and maintenance

A wet-and-dry cleaner still needs maintenance even when it can wash and dry its roller. Dirty-water tanks should be emptied promptly, hair and debris should be removed when necessary, and the cleaning head should be inspected for residue. Self-cleaning reduces manual work; it does not eliminate hygiene and maintenance.

Owners should also follow Roborock’s detergent guidance. Using a concentrated or foaming cleaner that is not intended for the machine can create residue or excessive foam and may affect the water path.

Is the F25 RT Gen 2 a robot vacuum?

No. The F25 RT Gen 2 is a powered wet-and-dry floor washer that the user pushes. If the priority is autonomous daily vacuuming, a robot is a different category. Technology Blog’s Tapo RV30C guide and Eufy Omni C20 guide cover robot-vacuum alternatives with a very different ownership model.

Who does it make sense for?

The F25 RT Gen 2 makes the most sense in homes dominated by sealed hard floors where spills, footprints, fine dust and everyday debris are common. It is less compelling if most rooms are carpeted or if the buyer primarily wants unattended cleaning while away from home.

For South African buyers, the value calculation should include local warranty support, replacement rollers and filters, detergent availability and the cost of those consumables. Those ownership details often matter more over several years than a small difference in suction claims.

Bottom line

Roborock F25 RT Gen 2 is a refinement of the company’s wet-and-dry floor-cleaning platform rather than a simple power increase. Its strongest selling points are the 20,000 Pa rated suction, updated edge and anti-tangle design, low-reach cleaning and local South African product support. The 38-minute Eco runtime is sufficient for many hard-floor homes, but buyers should compare the exact F25 variant rather than treating the whole Gen 2 family as one specification.
