Both robots’ mop pads typically last 2-3 months with regular use before needing replacement. Dreame replacement pads tend to be slightly cheaper due to higher market competition. The Roborock’s hot-water wash system may extend pad life slightly by keeping them cleaner between uses.Is the mechanical arm on the Saros Z70 reliable long-term?

The OmniGrip arm is still relatively new, so long-term reliability data is limited. Early owner reports are positive, and Roborock has a strong track record with hardware reliability. The arm does add a moving part that could theoretically fail, but Roborock’s warranty covers mechanical defects for the standard 1-2 year period.
