ZDNET has tested 10 robot vacuums for sand pickup, with the Ecovacs X8 Pro Omni being the clear favorite. The lab tested each robot vacuum through three tests over five sessions, totalling 15 tests per vacuum. Each robot vacuum was tested in a simulated living room on different floor types to determine the percentage of sand it picked up on hardwood, low-pile carpet, and mid-cile carpet. The robot vacuum with the best pickup performance was the X9 Pro Omni, picking up an average of 60.28% of sand across all three testing categories. The Roborock Saros 10R was the least successful robot vacuum, despite its 22,000Pa of suction and flagship model status. The results may vary depending on the type and condition of the flooring, the type of debris being picked up.
