A hub or wheel assembly includes a retaining element, biasing element, and hand-maneuverable release mechanism. The housing includes an axle bore configured to receive an axle and a pin sleeve including a first end in fluid communication with the axle bore, a second end, and a conduit between the first end and the second end. The retaining element is within the conduit and is configured to operatively engage a groove in an axle. The biasing element is within the conduit and is configured to bias the retaining element towards the axle bore. The hand-maneuverable release mechanism is configured to displace the retaining element away from the axle bore.

An autonomous floor cleaner can include a housing, a drive system for autonomously moving the housing over the surface to be cleaned, and a controller for controlling the operation of the autonomous floor cleaner. The drive system can include at least one drive wheel for driving the housing across a surface to be cleaned. The drive wheel can be selectively moved from an engaged or in-use position to a disengaged or maintenance position. In the disengaged or maintenance position, the wheel is disengaged from the autonomously moveable housing such that it can be pivoted, extended, removed, or otherwise moved farther away from the autonomously moveable housing.

A wheel to axle securement system (WASS) that facilitates securing a vehicle wheel to an axle, or removal of a vehicle wheel from an axle. The WASS includes a wheel hub with a centered opening, an axle, and a quick release ball lock pin that is dimensioned to be inserted into an axle insert within the axle. The wheel hub is placed onto the axle through the opening such that the axle end is adjacent an outer surface of the hub. The lock pin has at least two balls that extend from or retract into the pin's shaft. A button on the pin actuates an internal assembly. When the button is released, the balls extend outward. Once the hub is on the axle, the pin button is depressed and the pin is inserted into the axle insert. When the button is released the balls are located adjacent and in contact with the end of the axle insert, which functions as a barrier that precludes the pin from being removed from the insert. Once the pin is in place, the hub is secured onto the axle.

An axle assembly having a wheel flange with a central opening and a slot having an end dimensioned to fit within the wheel flange central opening. A molten binder, such as molten zinc, fills the space in between the wheel central opening and the shaft end. Upon cooling, the binder locks the wheel flange and shaft together.
