A fluid extracting device with a shaped head and associated systems and methods of use and manufacture. In one embodiment, the device includes an extractor head that includes an extractor port housing having a cavity configured to be coupled to a vacuum source. The extractor port housing includes a recessed surface and individual openings extending through the recessed surface and in fluid communication with an interior suction cavity. The extractor port housing can further include first and second lips each adjacent to opposite sides of the recessed surface and each configured to provide a squeegee function. In another embodiment, the device includes a tubular member and a handle operably coupled to the tubular member and including a suction control device. The suction control device is configured such that a user can simultaneously operate the device to control the suction and operate the extractor to remove fluid from a flooring surface.

1. An extractor head for removing fluid from an at least partially liquid-saturated surface, the extractor head comprising: an extractor port housing having a cavity positioned to be coupled to a vacuum source, the extractor port housing including—a recessed surface aligned with an elongated axis, and individual openings extending through the recessed surface and in fluid communication with an interior suction cavity of the extractor port housing, andwherein the extractor port housing further includes first and second lips each adjacent to an opposing side of the recessed surface, aligned with the elongated axis, and having a fixed shape that is generally convex relative to the recessed surface, and wherein the first lip is configured to provide an edge that directs liquid from the at least partially liquid-saturated surface toward the recessed surface when the first lip contacts the at least partially liquid-saturated surface with a contact force greater then another contact force applied to the second lip. 2. The extractor head of claim 1 wherein: the first lip is configured to provide a first squeegee function when a portion of the first lip is contacting and moving in a first direction across the at least partially liquid-saturated surface, andthe second lip is configured to provide a second squeegee function when a portion of the second lip is contacting and moving in a second direction across the at least partially liquid-saturated surface. 3. The extractor head of claim 1 wherein the individual openings are elongated, aligned with the elongated axis, and arranged in staggered rows that are also aligned with the elongated axis. 4. The extractor head of claim 1 wherein the recessed surface is concave and shaped to form a depression. 5. The extractor head of claim 1 wherein the fixed shape of the first lip is the same as the fixed shape of the second lip. 6. The extractor head of claim 1 wherein the first and second lips each have a rounded surface. 7. The extractor head of claim 1 wherein the openings are configured to draw the liquid from the first lip into the suction cavity via an applied suction force. 8. The extractor head of claim 1 wherein the first lip is further configured to direct the liquid toward the recessed surface when the first lip is contacting the at least partially saturated surface and the second lip is not contacting the at least partially liquid-saturated surface. 9. An extractor, comprising: a tubular member having a first end, a second end opposite the first end, and an outlet configured to be operably coupled to a vacuum source;a handle coupled to the tubular member towards the first end and including a suction control device positioned to control a fluid flow rate at which fluid is drawn through a portion of the tubular member, wherein the suction control device is positioned such that a user can simultaneously operate the suction control device to control the fluid flow rate and operate the extractor to remove liquid from a flooring surface; andan extractor head configured to be operably coupled to the tubular member at the second end, wherein the extractor head comprises— a recessed surface having openings extending through the recessed surface and configured to be in fluid communication with the tubular member, andfirst and second lips each adjacent to opposite sides of the recessed surface, wherein each of the first and second lips has an outer surface with a fixed shape that protrudes outwardly relative to the recessed surface, and wherein the outer surface is configured to direct the liquid from the flooring surface toward the recessed surface when (1) one of the first and second lips contacts the flooring surface with a contact force and (2) the other one of the first and second lips does not contact the flooring surface or contacts the flooring surface with lesser contact force. 10. The extractor of claim 9 wherein: the tubular member has a wall,the tubular member comprises suction control openings extending through the wall, andthe suction control device is configured to adjustably cover the suction control openings. 11. The extractor of claim 10 wherein the suction control device comprises a plate positioned to adjustably cover the suction control openings. 12. The extractor of claim 10 wherein the suction control device further comprises a gasket configured to adjustably cover the suction control openings. 13. The extractor of claim 10 wherein the suction control device further comprises: a plate positioned to adjustably cover the suction control openings;a lever arm pivotally coupled to the plate and a body of the handle; anda finger tab coupled to the lever arm. 14. The extract of claim 10 wherein the suction control device further comprises: a plate positioned to adjustably cover the suction control openings; anda capstan mechanism configured to hold the plate in at least a first fixed orientation and a second fixed orientation, wherein— in the first orientation, the capstan mechanism is configured to substantially cover the suction control openings, andin the second orientation, the capstan mechanism is configured to at least partially uncover at least a portion of the suction control openings. 15. The extractor of claim 9 wherein the recessed surface is concave and shaped to form a depression. 16. The extractor of claim 9 wherein: the first lip is configured to provide a first squeegee function when the extractor head is moved in a first direction across the flooring surface, andthe second lip is configured to provide a second squeegee function when the extractor head is moved in a second direction across the flooring surface. 17. The extractor of claim 9 wherein the outer surface of each of the first and second lips is rounded. 18. An extactor, comprising: a tubular member having a first end, a second end opposite the first end, and an outlet configured to be operably coupled to a vacuum source, wherein the tubular member includes a wall and a plurality of suction control openings extending through the wall, wherein the plurality of suction control openings includes a first opening and a second opening;a handle coupled to the tubular member towards the first end and including a suction control device positioned to control a fluid flow rate at which fluid is drawn through a portion of the tubular member, wherein the suction control device is positioned such that a user can simultaneously operate the suction control device to control the fluid flow rate and operate the extractor to remove fluid from a flooring surface, wherein the suction control device includes— a plate pivotally coupled to the tubular member such that the plate pivots at least between a first position and a second position, anda first plug element on the plate and projecting toward the tubular member,a second plug element spaced apart from the first plug element on the plate and projecting toward the tubular member,wherein in the first position the first plug element partially closes the first opening and the second plug element completely covers the second opening, and wherein in the second position the first plug element is completely removed from first opening and the second plug element only partially extends into the second opening; andan extractor head configured to be operably coupled to the tubular member at the second end wherein the extractor head comprises— a recessed surface having openings extending through the recessed surface and configured to be in fluid communication with the tubular member, andfirst and second lips each adjacent to opposite sides of the recessed surface, wherein each of the first and second lips an outer surface with a fixed shape that protrudes outwardly relative to the recessed surface. 19.
