What's good
- The biggest dust bag here (5 L, up to 150 days by Dreame's figure) and the biggest onboard bin (500 ml)
- Nothing in the base to fill, drain or descale
- Longest rated runtime on this page
What's not
- The base does not wash the mop pad: cleaning or replacing it is on you
- Dreame's page names no camera or structured-light obstacle avoidance, so tidy cables and socks before a run
- Lowest suction figure on this page
Our verdict
The right robot when the job is vacuuming. Most of the cost and maintenance of an Ultra-style dock is the mopping side (water tanks, hot washing, drying), and if you mostly have carpet or just want the hair picked up every day, this skips all of it and still empties itself for months.
