A vacuum cleaner that can quickly be configured in various operating modes, including a standard-style upright vacuum, upright vacuum capable of cleaning under furniture, stick vacuum, handheld vacuum, and pod vacuum. An example embodiment is a surface cleaning apparatus that includes an elongated support member, a handle coupled to an upper end of the elongated support member, a vacuum module slidably and detachably coupled to the elongated support member, and a hose coupled to the vacuum module and expandable to accommodate lower and upper positions of the vacuum module along the elongated support member. The surface cleaning apparatus can further include a floor nozzle detachably coupled to a lower end of the elongated support member and the hose.

Surface cleaning apparatus

A microneedle injection apparatus comprising a dual cover. The apparatus can include a housing having a base and a cavity; a microneedle array comprising a first side comprising a plurality of microneedles; and a microneedle array holder configured to hold a microneedle array and located in the housing. The microneedle array holder can be movable between a retracted position, and an extended position. The apparatus can further include a cover configured to be positioned to cover the opening in the base of the housing. The cover can include (i) a first portion configured to cover at least a portion of the base of the housing adjacent the opening, and (ii) a second portion configured to be received in the cavity of the housing and further configured to cover the plurality of microneedles on the microneedle array when the microneedle array holder is in the retracted position.
