Systems, apparatuses, and methods for determining item availability are provided. A computer implemented method for determining item availability in a shopping space comprising: receiving a request for an item for purchase from a customer, querying an inventory database to determine whether the item for purchase is in stock, in an event that the item for purchase is not in stock according to the inventory database: determining an out of stock response to present to the customer, in an event that the item for purchase is in stock according the inventory database: instructing a motorized transport unit to travel to a display space in the shopping space corresponding to the item for the purchase, determining whether the item is available in the display space based on information captured by one or more sensors of the motorized transport unit, and in an event that the item for purchase is not available in the display space: determining an item unavailable response to present to the customer.

An example high pressure ice-breaking machine with a double row of wheels comprises: a frame, a plurality of wheels, and a plurality of spring mechanisms. The plurality of wheels comprises: a front ice-breaking wheel group and a rear ice-breaking wheel group. The plurality of wheels include a total of two rows of wheels, which include a front ice-breaking wheel group and a rear ice-breaking wheel group. The plurality of wheels are positioned horizontally under the frame. The front ice-breaking wheel group and the rear ice-breaking wheel group include a same number of wheels. The two rows of wheels are staggered in double rows from front to back. A first ice-breaking wheel from the front ice-breaking wheel group and a second ice-breaking wheel from the rear ice-breaking wheel group form a staggered wheel pair, and the first ice-breaking wheel and the first ice-breaking wheel are hinged to a same spring mechanism.

An ice removal machine provides crushing and removing ice formed on hard surfaces such as sidewalks or external stair steps in front of houses. A rotating pulley wheel fixed on an electric motor generates an oscillation movement for a nailed hammer system. The nails of the hammer system are forced dropping on the ice layer covered a rigid surface; thereby crush the ice into small pieces. The machine is provided by an attached shovel bucket fixed on front of it in order to collect the residual ice and moves it away from the surface. The machine includes a box cart carrier movable by hand and it is provided by front and back wheels and a handle drive that a user holds. The machine is in small reasonable size for private use at home.

A plurality of lockers can each serve to contain items that have been ordered by a customer. By one approach these lockers are stored in a locker storage facility. By one approach these lockers are configured such that a motorized transport unit can physically engage the locker in order to move the locker. So configured, a central computer system can be configured to select a particular motorized transport unit to retrieve a particular locker that has been previously associated with a particular entity (such as a particular customer or their designated agent) and to make that locker available to that particular entity such that the latter can retrieve their item or items from that locker.
