What the differences mean

Mopping

The Ecovacs DEEBOT T90 Omni scrubs with a self-washing roller, lifts it over carpet and dries it at the dock. The Shark PowerDetect Self-Empty has no mopping function at all, so its floor care stops at vacuuming.

Detergent dosing

The Ecovacs DEEBOT T90 Omni dispenses cleaning solution automatically as part of its station routine. The Shark PowerDetect Self-Empty has no mop to feed, so there is nothing to dose.

Suction rating

The Ecovacs DEEBOT T90 Omni is rated at 30,000 Pa. Shark does not publish a pascal figure for the PowerDetect Self-Empty, so there is no like for like number to compare it against.

Runtime

The Ecovacs DEEBOT T90 Omni is rated for 260 minutes per charge and the Shark PowerDetect Self-Empty for 110, which lets the Ecovacs cover a large home in fewer charge cycles.

Noise and price

The Ecovacs DEEBOT T90 Omni is rated at 60 dB, and owners describe it as quiet for its power. The Shark PowerDetect Self-Empty is the more affordable of the two, which is its main advantage.

Which one to buy if

What owners say

Both groups of owners describe a machine that needs very little attention, then emphasise different things. Ecovacs DEEBOT T90 Omni owners who moved up from pad mops call the roller a generational change, saying it scrubs with fresh water instead of dragging a wet pad, and they single out how quiet it stays for its rated suction and how the anti-tangle brush handles long hair. Their recurring criticism is the app and mapping, described as adequate rather than polished, with occasional odd routing. Shark PowerDetect Self-Empty owners are more focused on reliability, crediting NeverStuck for clearing thresholds and the bagless HEPA base for a month between empties, while calling the SharkClean app basic and reporting setup and Wi-Fi pairing friction.
