Data from the official Ecovacs and iRobot sites.
2026 verdict
For buyers who rank suction and battery life first, the Ecovacs DEEBOT T80S Omni is the better of these two robot vacuums.
It is rated at 24,800 Pa against 7,000 Pa on the iRobot Roomba Plus 505 and runs about 236 minutes against 180, with a 4 L water tank. Both bring Apple Home, SmartThings and Matter in through Matter, and both docks empty, wash and dry the mop the same way. The iRobot Roomba Plus 505 keeps a 5 GHz Wi-Fi band, where the Ecovacs is 2.4 GHz only. Choose the Ecovacs DEEBOT T80S Omni for carpet, pets and fewer refills, and the iRobot Roomba Plus 505 if a dual-band network and the iRobot app and support network are what you value.

What the differences mean
Suction power
The Ecovacs DEEBOT T80S Omni is rated at 24,800 Pa against 7,000 Pa on the iRobot Roomba Plus 505, so it lifts more pet hair and embedded dust from rugs and carpet.
Battery life
Ecovacs rates the DEEBOT T80S Omni at 236 minutes and iRobot rates the Roomba Plus 505 at 180 minutes, a clear edge on larger floors.
Wi-Fi band
The iRobot Roomba Plus 505 supports both 2.4 GHz and 5 GHz Wi-Fi, where the Ecovacs DEEBOT T80S Omni is 2.4 GHz only. Both carry Bluetooth.
Water tank
The Ecovacs DEEBOT T80S Omni lists a 4 L tank, and iRobot does not publish that capacity for the Roomba Plus 505, so the Ecovacs is the known quantity.
Mop style
The Ecovacs DEEBOT T80S Omni uses a self-washing OZMO roller cleaned with hot water at the dock, while the iRobot Roomba Plus 505 uses lifting mop pads. Both dry the mop after washing.
Which one to buy if
- pets and carpet dominate your home
The 24,800 Pa of the Ecovacs DEEBOT T80S Omni pulls far more out of carpet than the 7,000 Pa iRobot Roomba Plus 505.
- you want the longest run between charges
The Ecovacs DEEBOT T80S Omni is rated for 236 minutes against 180 minutes on the iRobot Roomba Plus 505.
- your network offers a 5 GHz band
Only the iRobot Roomba Plus 505 connects on 5 GHz, while the Ecovacs DEEBOT T80S Omni is limited to 2.4 GHz.
- you want a roller mop washed with hot water
The Ecovacs DEEBOT T80S Omni washes its OZMO roller at the dock, where the iRobot Roomba Plus 505 uses pads.

What owners say
Owners of both describe a dock that takes over the messy parts, emptying the bin and washing and drying the mop after every run, and both groups say the mapping is accurate enough to trust with room-by-room schedules. Ecovacs DEEBOT T80S Omni owners emphasise quiet operation and suction strong enough for pet hair on rugs and hard floors, and their recurring complaint is the app, which they describe as less refined on iOS when fine-tuning maps. iRobot Roomba Plus 505 owners point to fast mapping and strong pet-hair pickup, and warn about noise during the dock's self-cleaning cycle, occasional navigation faults after a few months and warranty trouble for third-party buyers.
