A water squeezing type roller cleaning device, comprising a device main body (10), a rolling cleaning mechanism (20), a water squeezing rod (30), and a base (40). The rolling cleaning mechanism (20) comprises a roller (21), a driving mechanism, and a spray cleaning mechanism (22). The roller (21) is exposed at the bottom of the device main body (10) and is transmittingly connected to the driving mechanism. An accommodating cavity (11) is provided in the device main body (10). The accommodating cavity (11) is provided with a receiving gap. The spray cleaning end of the spray washing mechanism (22) extends into the accommodating cavity (11). The base (40) is provided with an assembly cavity (41). The water squeezing rod (30) is disposed in the assembly cavity (41), and when the device main body (10) is disposed in the assembly cavity (41), abuts against the roller (21), so as to achieve periodic cleaning and water drainage of the roller (21), thereby achieving thorough cleaning of its outer peripheral surface. Moreover, when the spray cleaning mechanism (22) completes the cleaning of the roller (21) and stops spraying a cleaning liquid to the roller (21), only the roller (21) and the water squeezing rod (30) are required to work in conjunction to effectively remove excess water of the roller (21), so that after the roller is cleaned, its water content is effectively controlled.
