    Xiaomi 5 Pro: 80°C mop wash and AI camera

    Check price on AmazonAffiliate link

A self-cleaning dock rinses the mop between rooms or after a run, but cold water struggles with kitchen grease. Docks that heat the wash water are meant to loosen that residue so the mop goes back out cleaner, and warm air drying afterwards stops a damp pad sitting in the base. The wash temperature is the figure to look for, and it varies a lot: from around 45°C up to 80°C on the listings here. Drying matters just as much, so check whether the dock uses hot air or cool air and how long it runs. This guide compares six robots on the stated wash temperature, drying method, mop type, suction and whether the dock also empties the dust bin, so you know how much is left for you to do.

The products in detail

No. 1 · ECOVACS

Ecovacs Deebot T80 Omni: wash at 40 to 75°C by dirt level

A roller mop that rinses itself while it works, a dock that sets wash temperature by dirt level and AIVI 3D 3.0 avoidance. The most complete mopping package here.

In its favour

  • Temperature Controlled Pad Wash 2.0 chooses between 40 and 75°C by room and dirt level.
  • TruEdge 2.0 pushes the roller out along edges, and the side brush extends into corners.
  • Carpet Priority vacuums every rug first with a dry pad to avoid wetting them.

Good to know

  • This listing does not mention the dock emptying the dust bin.
  • Roller width is not stated, so coverage per pass is unclear.

No. 3 · Xiaomi

Xiaomi 5: 80°C washing with scraper-cleaned washboard

The same 80°C wash as the 5 Pro, plus dual rotating scrapers that clean the washboard during each wash. A fit for buyers who want the hot wash without the camera.

In its favour

  • The Item Highlight lists 80°C hot water washing at the base station.
  • Dual rotating scrapers clean the washboard while the mop is washed, so the tray needs less attention.
  • Retractable dToF radar lets it get under furniture as low as 9.5 cm.

Good to know

  • The listing does not mention mop drying.
  • There is no AI camera, so obstacle recognition is less detailed than on the 5 Pro.

No. 6 · Xiaomi

Xiaomi 5 Pro: 80°C mop wash and AI camera

Xiaomi's dToF radar rises in open rooms and lowers in tight spaces, letting the robot reach areas as low as 9.5 cm. Suits furniture with a gap a little over 9.5 cm rather than true low sofas.

In its favour
