Published on 2026-10-09

## Price seen in shops

According to the brand's website, the [Dreame X60 Max Ultra Complete](/robots/dreame-x60-max-ultra-complete) was listed at $1,349.99 on the US market during the Prime Day promotion, and at $1,499.99 on the brand's US store during another promotion, with a usual price shown of $1,699.99 (manufacturer's claims, source consulted on 8 October 2026). The [Roborock Saros 20 Flow](/robots/roborock-saros-20-flow) appears at $1,699.99 on Amazon, according to vacuumwars.com, with the price widget timestamped 28 September 2026. All three figures are in US dollars, but they reflect different sales conditions and dates: they are observed prices, with no common reference price.

## Charging time

According to Dreame's website, the Dreame X60 Max Ultra Complete goes from 9% to 80% charge in 80 minutes, based on internal lab data (manufacturer's claim). According to Roborock's website, the Roborock Saros 20 Flow takes 150 minutes for a full charge, based on the manufacturer's internal tests (manufacturer's claim). The two measurements do not cover the same cycle: a partial charge on one side, a full charge on the other.

## On-robot image processing

According to Dreame's website, "the recognition algorithm runs exclusively on the robot vacuum", wording that applies to the image recognition algorithm (manufacturer's claim). Roborock's website states that visual data is processed on the device ("processing all visual data securely on-device", manufacturer's claim).

## LiDAR

According to Dreame's blog, the X60 Max Ultra Complete has a "VersaLift LDS sensor", a retractable LDS turret that deploys in open spaces and lowers under low furniture (manufacturer's claim). According to Roborock's website, the Saros 20 Flow has a "full LiDAR system" (manufacturer's claim). The detail of a retractable turret appears only for the Dreame model in our sources.

## Camera

According to Dreame's blog, the X60 Max Ultra Complete uses "two 120° wide-angle AI cameras" (manufacturer's claim). For the Saros 20 Flow, vacuumwars.com mentions a "camera-based Reactive AI system". Both sources mention cameras, but we found no sourced figure for the number of cameras or their viewing angle on the Roborock side.
