Deebot T80 Omni
A robot that vacuums and mops with a roller. Its dock empties the bin, washes the mop and dries it.
Vacuum and mopPrice band: $500 to $1,000
Our take
A roller mop that the dock washes and dries, and up to 297 minutes on a charge, all for $500 to $1,000. The dock doesn't add detergent.
By Emma Walsh
Big houses are hard on robot vacuums, because a battery that runs flat halfway down the hall means the job gets finished after a recharge. The T80 Omni is the robot we’d look at first for a large home. Its 6,400 mAh battery matches the biggest in our list and keeps it going for up to 297 minutes.
It spends that time vacuuming at 18,000 Pa and mopping with a roller, which is why it’s the best overall pick in our guide to vacuum and mop combos. The roller pushes down on the floor with 3,700 Pa of pressure, reaches out to edges and corners, and lifts 1 cm clear when the robot meets carpet. The side brush is an anti-tangle design that doesn’t extend, and a front camera helps the robot around things left on the floor.
The dock picks up the chores afterwards. It empties the 220 ml bin into a 3-litre bag and gives the roller a hot wash, in water of up to 75°C. Hot-air drying follows and takes two hours, or three or four if you set it that way. The clean water tank holds 4 litres and the dirty water tank holds 2.2 litres.
Check two measurements before you order. The robot stands 9.8 cm tall and gets over a sill of 2 cm with its mop attached, so a very low couch or a taller sill rules it out. The dock is 33.8 cm wide, 45.9 cm deep with its ramp and 50 cm high. The robot weighs 4.95 kg and makes 63.4 dBA vacuuming in standard mode.
The one job this dock skips is detergent, because it doesn’t add any. The Deebot X8 Max Pro Omni mops with a roller too and its dock does add it, from one band up and with a little less suction at 16,600 Pa. We don’t think one job is worth a whole band, so for most homes we’d stay with the T80.
