Two other Roborock models from the same period, the
S4 and the
S6, share the S5 Max’s suction rating. On suction the S5 Max ranks 38th of
38 in the chart below, which pairs Roborock’s
current active lineup with the S5 Max itself.
Roborock's active lineup, suction power (Pa)
Since suction does not separate the three, noise does. The S4 is rated at
68 dBA, the S5 Max at 60 dBA and the S6 at 50 dBA. In the noise
chart the S5 Max ranks 3rd of
16 Roborock models with a noise rating.
Roborock's active lineup, noise level in dBA (lower is better)
Against the S4, the S5 Max adds a water tank and electronic water flow control,
which the S4 lacks, and its dustbin is a little larger (460 ml against
420 ml). Against the S6, it takes longer to charge: 240 minutes, where the
S6 needs 150.
Placed between the other two, the S5 Max is quieter than the S4 and able to mop,
but louder and slower to charge than the S6.
