iRobot Roomba 505X vs Roborock Qrevo Curv 2 Flow

Full Robot Vacuums comparison in 2026

Updated November 2026
Data from the official iRobot and Roborock sites.
2026 verdict
Worried about a mop pad that keeps pushing dirty water around?
The Roborock Qrevo Curv 2 Flow handles it better than the iRobot Roomba 505X. Its roller mop is fed clean water through eight hydration points while an internal scraper lifts the dirty water away, so the surface touching the floor is rinsed as it works, where the iRobot Roomba 505X spins pads that its AutoWash dock washes and heat-dries between runs. The Roborock also leads on suction at 20000Pa against 7000Pa, on battery at 242 minutes against 180, and on water tank capacity at 4 L, while the iRobot does not publish its tank. The iRobot Roomba 505X keeps the lower price, dual-band Wi-Fi and Matter support that brings Apple Home, SmartThings and Home Assistant. Note that the Roborock Qrevo Curv 2 Flow does not clean tight against baseboards or under low cabinet kicks. Choose the Roborock Qrevo Curv 2 Flow for roller mopping and a longer run, and the iRobot Roomba 505X for the lower price, the known ecosystem and a slimmer 107 mm body against 119 mm.

What the differences mean

Mop system

The Roborock Qrevo Curv 2 Flow feeds clean water to a roller through eight hydration points and scrapes the dirty water away as it scrubs, so it is rinsing while it mops. The iRobot Roomba 505X spins two pads that the AutoWash dock washes and heat-dries between runs.

Suction power

20000Pa on the Roborock Qrevo Curv 2 Flow against 7000Pa on the iRobot Roomba 505X, which is a large gap on carpet and embedded pet hair.

Battery life

The Roborock Qrevo Curv 2 Flow is rated at 242 minutes, against 180 on the iRobot Roomba 505X, so it covers a larger single floor without a mid-run recharge.

Water tank capacity

The Roborock Qrevo Curv 2 Flow carries a 4 L water tank. The iRobot Roomba 505X draws from its dock but does not publish a water tank capacity, so the two cannot be compared on that figure.

Height and clearance

The iRobot Roomba 505X is 107 mm tall and the Roborock Qrevo Curv 2 Flow is 119 mm, so the iRobot is the slimmer body and reaches under lower furniture.

What owners say

Roborock Qrevo Curv 2 Flow owners describe running it daily for weeks without rescuing it, and they call the roller mop the reason they picked it: floors stay visibly cleaner with far less intervention, and the anti-tangle brushes leave hair in the bin. The app with per-room routines and automatic carpet boost earns repeated praise. Their warnings are edge cleaning that stops short of baseboards, a minority seeing streaks on hardwood, and routine cleaning of the roller, scraper and dirty-water tank. iRobot Roomba 505X owners highlight the AutoWash dock and reliable pet-hair pickup, and mention a loud cleaning cycle and fiddly first Wi-Fi pairing.
