SYSTEM AND METHOD TO DRIVE VACUUM EXCAVATOR
A system to drive vacuum equipment on a truck having an engine and a transmission includes a power take-off (PTO) unit configured to be coupled to a PTO port located on a side of the transmission. The system also includes a PTO shaft coupled to the PTO unit, vacuum equipment mounted to the truck, and a first gear box coupled to the PTO shaft and the first gear box configured to transfer power to the vacuum equipment. In addition, the system includes at least one belt coupled to the gear box, where the at least one belt drives additional auxiliary equipment. The additional auxiliary equipment comprises at least one of a water pump and a hydraulic pump, where the hydraulic pump is configured to stop and reverse a flow of hydraulic fluid to stop and reverse a rotational direction of air through the blower.
HAND-HELD DRAIN OPENING APPARATUS
A portable and compact, hand-held electrically powered vacuum tool, designed expressly for suctioning clogs from the drains and traps of sinks and bathtubs to pull clogs out of drains and traps thereby clearing the clog without use of chemicals and recover items such as rings and toothpaste-tube caps that have gone down the drain.
Vacuum
The present invention is directed to a vacuum including a dust extraction system. The system includes a filter assembly, an airflow generation assembly, and valve assembly. The airflow generation assembly is configured to draw contaminated air toward the filter assembly and exhaust filtered air as a discharge stream. The filter assembly is configured to remove contaminants from the contaminated airflow by capturing particulate material suspended within the airflow. The valve assembly is configured to selectively direct filtered airflow into the filter assembly such that the filtered air stream cleans the filter.
WET DRY APPLIANCE
A cleaning device and methods for cleaning are provided. In one embodiment, the cleaning device includes a head assembly, a body assembly, and a handle assembly. The cleaning device also includes components that enable the cleaning device to operate in dry cleaning modes and wet cleaning modes. Dry cleaning modes can employ a vacuum assembly, including a motor, tubing, and a fluid recovery tank in order to draw in debris and waste into a fluid recovery tank. Wet cleaning modes can further employ a fluid supply tank, a pump, and tubing in order to supply fluid to a brushroll to aid in a cleaning process.
SURFACE CLEANING APPARTUS
A surface cleaning apparatus such as an extractor has a fluid flow path extending from a dirty fluid inlet head to a clean air outlet. The fluid flow path upstream of the separation stage comprises a removable portion.
Suction apparatus
An apparatus may include a first layer that includes a plurality of inlets and a surface feature; a second layer, where the surface feature opposes the second layer; an outlet, and a pattern defined on at least one of the first layer and the second layer, where the pattern defines a suction path from each inlet of the plurality of inlets to the outlet.
Debris evacuation for cleaning robots
A robot floor cleaning system features a mobile floor cleaning robot and an evacuation station. The robot includes: a chassis with at least one drive wheel operable to propel the robot across a floor surface; a cleaning bin disposed within the robot and arranged to receive debris ingested by the robot during cleaning; and a robot vacuum configured to pull debris into the cleaning bin from an opening on an underside of the robot. The evacuation station is configured to evacuate debris from the cleaning bin of the robot, and includes: a housing defining a platform arranged to receive the cleaning robot in a position in which the opening on the underside of the robot aligns with a suction opening defined in the platform; and an evacuation vacuum in fluid communication with the suction opening and operable to draw air into the evacuation station housing through the suction opening.
Surface cleaning apparatus
A surface cleaning apparatus includes include at least a recovery system for removing the spent cleaning fluid and debris from the surface to be cleaned and storing the spent cleaning fluid and debris. The recovery system is provided with a recovery tank having a removably strainer that is configured to strain large debris and hair out of the recovery tank prior to emptying the recovery tank.
SYSTEMS AND METHODS FOR CLEANING A LAVATORY FLOOR
A system includes a dry floor assembly that is configured to be located within an interior space. The dry floor assembly includes a vacuum layer. A vacuum system is coupled to the vacuum layer. The vacuum system is configured to remove liquid from the dry floor assembly via the vacuum layer.
Surface cleaning apparatus
A surface cleaning apparatus includes a housing including an upright handle assembly and a base mounted to the upright handle assembly and adapted for movement across a surface to be cleaned. The surface cleaning apparatus is further provided with a fluid delivery system comprising a fluid dispenser configured to dispense fluid to a brushroll and at least one fluid delivery channel forming a portion of a fluid delivery pathway. The fluid delivery channel can extend adjacent to a portion of the suction nozzle assembly. An interference wiper interfaces with a portion of the brushroll to remove excess liquid from the brushroll.
