ECOVACS DEEBOT T90 PRO Omni Robot Vacuum and Mop

Station and running costs

The station carries most of the ongoing ownership cost. The roller mop, anti-tangle main brush, antibacterial filter, antibacterial dust bag and cleaning solution are all sold separately, and only a 260 ml solution bottle ships in the box. The station is not plumbed: EcoVACS lists automatic upper and lower water supply and auto drain as not compatible, so the 4 L clean and 2.2 L dirty tanks are filled and emptied by hand, and the stated 400 m² per tank sets how often that happens. The support page documents maintenance guides for bag, filter, brushes, dust bin, roller mop, washing tray and both tanks, along with alarms for sensor dust, a stuck bumper, tangled mop, abnormal tanks and an abnormal washing tray.

Noise and water

The published noise figures are the ones worth remembering: 60 dBA for sweeping or mopping, but 76 dBA for standard-mode dust collection at the station, with 71 dBA in silent mode. That station figure is the loudest number in the product and is easy to miss because the 60 dBA figure is the one repeated in marketing. Water is the other practical limit: 4 L clean and 2.2 L dirty with no plumbing, so the station is filled and emptied manually.

Evidence gaps

No instrumented test of the T90 PRO Omni was located, and no results were read from RTINGS, Wirecutter, Tom’s Guide, CNET, PCMag or a lab. The closest independent source is Vacuum Wars’ Ecovacs buying guide, which restates the specification set and pricing tier without publishing test measurements. Vacuum Wars does warn that the “Plus”, “Pro”, “Max” and “Omni” naming is largely marketing and that the T series is the most confusing in the brand, with wide feature variation between families. No Reddit thread, specialist forum post or retailer Q&A about this exact model was found, so no reliability, app or consumable-life verdict can be stated.

Warranty and support

ECOVACS’ US online-store returns and warranty page states a 30-day refund or exchange period for store purchases, with the original receipt, original packaging and all included accessories, and buyer-paid return shipping unless the product is defective. That page states products are warranted against defects in material and workmanship for 12 months from the date of purchase, and that products not bought from ECOVACS or its dealers are not covered. The T90 PRO Omni instruction manual was not read, so a model-specific warranty statement has not been verified, and a third-party marketplace buyer should confirm coverage in writing before purchase.

Which model this is

This page covers the ECOVACS DEEBOT T90 PRO Omni, the US model with a 110 V station heating module and the part name “Automated Vacuum Cleaner (30,000Pa Suction, 10.63 inch Long Roller Mop, BLAST)”. The listing this page covers is ASIN B0GJ5S4V78. Do not merge it with the DEEBOT T90S PRO Omni, the DEEBOT T90 MAX PLUS Omni, or the T90 PRO Omni and Buddy Kit, which is a bundle that adds a second device rather than changing the vacuum itself. Accessory pages group the T90 with other models where the main brush, roller mop, filter and dust bag are shared, and that shared-parts statement is not evidence of shared cleaning performance. The direct product page read as sold out at the time of this check.
