ECOVACS DEEBOT T90 PRO Omni Robot Vacuum and Mop, 30000Pa Blast Suction

Why it's worth it

The OZMO Roller 3.0 is a 10.6-inch roller that rinses itself continuously while it mops, so it lays down clean water instead of pushing dirty water around. Pair that with a lot of suction headroom and an edge-hugging roller, and it's the better choice for busy kitchens.

A pad drags. A roller scrubs. That's the whole argument, and after a week of real cooking you can see it on the floor near the stove. The roller here spins under pressure and gets rinsed as it goes, with a scraper pulling the dirty water off into a separate tank. Owners consistently single out the mopping as the strongest part of this machine.

The suction number is marketing, and it still cleans very well. TechRadar's benchmarking suggests real-world pickup plateaus around 6,000 Pa on low and medium pile carpet, with more mainly helping on deep pile and heavily soiled rugs. So don't read 30,000 Pa as five times better than a 6,000 Pa robot. Read it as plenty of margin, which is what you want with a shedding dog in the house.

What we like

• +A pad drags. A roller scrubs
• +The suction number is marketing, and it still cleans very well
• +TruEdge 3.0 pushes the roller about 0.6 inches past the body so it can scrub along baseboards, and ZeroTangle 4.0 steers long…
• +It handles the practical stuff too

What to know

• –The app and mapping are the weak spot
• –It's a tall, heavy dock, and the roller system has its own upkeep
