Abstract: The invention provides a rugged cleaning device configured to clean outdoor surfaces using a variety of fluids and techniques. The outdoor cleaning device includes a brush head, a motor and a transmission for providing a driving force to the brush head, a fluid tank for storing a fluid (e.g., a cleaning solution or detergent), and a controller for controlling mixing (or not mixing) the fluid stored in the fluid tank during operation of the outdoor cleaning device. The controller may enable fluid from the cleaning tank to be mixed with a second fluid (e.g., water) prior to being dispensed via a plurality of nozzles. The nozzles may be formed via grooves on an inner cover and an outer cover may be provided to close off the grooves to form fluid channels. The fluid channels enable the distribution of cleaning fluids in various directions, enhancing the brush head's cleaning capability.

Abstract: The invention provides a rugged cleaning device configured to clean outdoor surfaces using a variety of fluids and techniques. The outdoor cleaning device includes a brush head, a motor and a transmission for providing a driving force to the brush head, a fluid tank for storing a fluid (e.g., a cleaning solution or detergent), and a controller for controlling mixing (or not mixing) the fluid stored in the fluid tank during operation of the outdoor cleaning device. The controller may enable fluid from the cleaning tank to be mixed with a second fluid (e.g., water) prior to being dispensed via at least one nozzle. The at least one nozzle may be secured to a guard cover via grooves on an inner guard cover and an outer guard cover. The nozzle(s) enables the distribution of cleaning fluids in various directions, enhancing the brush head's cleaning capability.
