It cleans and mops with dual pads and an AutoWash dock that empties the bin and washes and dries the pads, and it is the only one of the two that joins a 5 GHz Wi-Fi network, so setup on a modern router is simpler. The Roborock Saros 10R answers with far more suction, 22,000 Pa against the 7,000 Pa iRobot rates, a slimmer 79.8 mm body that slips under low furniture, a riser chassis that climbs tall thresholds, and solid-state LiDAR that maps fast. Pick the Roborock Saros 10R if raw suction, a low profile or threshold climbing matter most, and the iRobot Roomba Plus 505 for the same hands-off combo routine at a friendlier price with dual-band Wi-Fi.

What the differences mean

Suction power

The Roborock Saros 10R is rated at 22,000 Pa, more than three times the 7,000 Pa of the iRobot Roomba Plus 505. On carpet and heavy pet hair that is the difference you feel, because the extra pressure lifts embedded dirt the smaller motor leaves behind.

Height and thresholds

The Roborock Saros 10R stands 79.8 mm tall and uses a riser chassis to climb high thresholds, so it reaches under low sofas and moves between rooms without help. The iRobot Roomba Plus 505 is 106 mm tall, which rules out some low furniture and raised doorways.

Wi-Fi bands

The iRobot Roomba Plus 505 connects on either 2.4 GHz or 5 GHz Wi-Fi, which makes pairing easy on a modern router. The Roborock Saros 10R is 2.4 GHz only, so a router that keeps its bands separate needs the 2.4 GHz one free at setup.

Dock and mop routine

Both docks empty the bin and wash and dry the mop pads, but the Roborock Saros 10R also refills its own water tank and dispenses detergent from a 4 L reservoir. The iRobot Roomba Plus 505 has no automatic detergent dispenser, so solution is added by hand.

Which one to buy if

What owners say

Owners of both of these robots praise the same thing: a dock that washes and dries the mop pads and takes most of the weekly upkeep off their hands. iRobot Roomba Plus 505 owners single out how fast and accurate the LiDAR map is, how well it pulls pet hair off mixed hard floors and carpet, and how much the AutoWash dock removes from the routine; their warnings are about noise during the self-cleaning cycle and a minority who hit navigation or bumper errors after a few months. Roborock Saros 10R owners talk more about cleaning power, describing strong suction and higher-pressure mops that scrub up paw prints, navigation that avoids furniture without scraping it, a slim body that climbs high thresholds and brushes that stay clear of long hair; their complaints are that no floor cleaner is included, that it uses more water than older models, and that the silicone brushes struggle on deep-pile rugs.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.

Frequently Asked Questions

Which is better overall: iRobot Roomba Plus 505 or Roborock Saros 10R?

The iRobot Roomba Plus 505 wins as the better value. It is the more affordable and better reviewed of the two and it matches the hands-off dock routine, while the Roborock Saros 10R counters with much more suction, a slimmer body and threshold climbing. Pick the Roborock if suction and low-furniture reach lead your list.

What is the biggest difference between the iRobot Roomba Plus 505 and the Roborock Saros 10R?

Suction and size. The Roborock Saros 10R is rated at 22,000 Pa and stands 79.8 mm tall with a riser chassis, against 7,000 Pa and 106 mm on the iRobot Roomba Plus 505, so it cleans deeper and fits lower.

Which one has stronger suction?

The Roborock Saros 10R, by a wide margin: 22,000 Pa against the 7,000 Pa of the iRobot Roomba Plus 505. If carpet and pet hair pickup are the priority, that is the model to choose.

Do these robot vacuums need 5 GHz Wi-Fi?

No, but the iRobot Roomba Plus 505 supports both 2.4 GHz and 5 GHz, so it pairs easily on a modern router. The Roborock Saros 10R is 2.4 GHz only.

Who should buy the iRobot Roomba Plus 505?

Buyers who want a genuine vacuum-and-mop routine handled by a self-washing dock, with dual-band Wi-Fi and the lower cost, and who do not need the deepest suction or a low-profile body.

Who should buy the Roborock Saros 10R?

Homes with deep carpet, low furniture or tall thresholds, where the extra suction, the 79.8 mm body and the riser chassis of the Roborock Saros 10R do the work the iRobot Roomba Plus 505 cannot.
