2026 verdict
Hands-off cleaning is the dividing line: the iRobot Roomba Plus 505 washes and dries its own mop pads, which makes it the better robot vacuum of this pair.

Its AutoWash dock empties the bin, rinses and dries the pads and lifts them over rugs, and the robot adds a longer 180 minute battery, 7000 Pa of suction and dual-band Wi-Fi. The SwitchBot K11+ is the more affordable and far more compact option, a 248 mm robot with a small self-emptying dock, quiet running and the same Matter, Apple Home, Alexa, Google Home, SmartThings and Home Assistant support, but its mop is a moistened pad you rinse by hand. Choose the iRobot Roomba Plus 505 if you want vacuuming and mopping to look after themselves, and the SwitchBot K11+ for a small apartment or tight furniture where size and price matter more than the mop.

What the differences mean

Mopping

This is the real gap. The iRobot Roomba Plus 505 has a mop its dock washes and dries, and it lifts the pads over rugs. The SwitchBot K11+ uses a moistened pad with no washing, drying or lifting, so it wipes floors rather than mopping them and the pad is yours to rinse.

Size

The SwitchBot K11+ measures 248 mm across and 92 mm tall, small enough to reach corners and chair legs a full-size robot misses. The iRobot Roomba Plus 505 is 357 mm wide and 106 mm tall, with a much larger dock to find room for.

Battery

The iRobot Roomba Plus 505 runs for 180 minutes against 150 on the SwitchBot K11+. Both return to recharge on their own, so the gap shows only in larger homes where the smaller robot has to stop mid-run.

Wi-Fi

The iRobot Roomba Plus 505 joins 2.4 GHz and 5 GHz networks, while the SwitchBot K11+ is 2.4 GHz only. Both carry Bluetooth for pairing. On a combined dual-band router, the Roomba is the easier of the two to pair.

Which one to buy if

What owners say

Owners of both robots agree on two things: fast, accurate LiDAR mapping and strong pet hair pickup for the size of the machine. iRobot Roomba Plus 505 owners single out the AutoWash dock coming back mid-run to rinse the pads and then emptying and drying everything, while their warnings are about noise during the dock's self-cleaning cycle, bumper-stuck or docking errors a few months in and warranty trouble when bought from third-party sellers. SwitchBot K11+ owners talk about how compact the robot and dock are, an anti-tangle brush that stays free of long hair and a year of spare consumables in the box, and they complain that the pad is only a wipe, that hair gathers at rug edges and that the robot can stop with a lidar-blocked error under very low furniture.

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.
