The invention relates to the field of cleaning instruments, in particular to a cleaning
robot. The
robot comprises a water tank, a
brush disc mechanism and a water suction mechanism, the
brush disc mechanism comprises a
brush disc and a water spraying
pipe, an inlet of the water spraying
pipe is communicated with the water tank, an outlet of the water spraying
pipe is formed in the brush disc, andthe water suction mechanism comprises a water suction rake, a
sewage suction pipe and a suction fan arranged on the water tank, an air inlet of the suction fan is communicated with the water tank; the water suction rake is connected with the water tank through a
sewage suction pipe, the water tank is a single water tank, a filter
cartridge is arranged in the water tank, two spaces are formed inside and outside the filter
cartridge in the water tank, one space is used as a clear
water area, the other space is used as a
sewage area, the sewage suction pipe sucks sewage into the sewage area, andthe
water spray pipe is communicated with the clear
water area. Only one water tank needs to be designed to contain
clean water and sewage at the same time, a power device for sewage to flow to the
clean water is omitted, the structure is simplified, and cost is reduced.
