摘要： A carpet extractor includes a base assembly 1 including a housing 10 which selectively receives a recovery tank 22 for collecting dirty cleaning fluid. A first supply tank 14 for concentrated cleaning fluid and a second supply tank 15 for clean water are mounted on an inverted Y-shaped handle assembly 12. The handle assembly includes a central member 334 with a hand grip 336 at its upper end and two splayed leg members 338, 342, 340, 344, which define a triangular shaped gap therebetween. The two tanks are removably mounted in the gap. The cleaning fluid tank is supported on a shelf 346, which spans the gap between the leg members. The water tank is pivotally mounted on two projections 374 on the leg members to allow for easy removal and replacement on the handle. The arrangement of tanks in the gap allows for large capacity tanks, a well-balanced handle, ease of removal of the recovery tank without the need for removing either of the two supply tanks, and ease of refill of the supply tanks.

摘要： A bagless canister vacuum cleaner includes a selectively removable dirt cup, and an airstream flows rotationally through the dirt cup between an interior wall of the dirt cup and a filter assembly selectively mounted in the dirt cup so that entrained contaminants are separated from the airstream flowing through the dirt cup and collected by the dirt cup. The filter lies substantially parallel to the support surface on which the vacuum cleaner is supported. A cover member is connected to the main housing, and the cover member is selectively movable to and held in an operative position in covering relation with an open first end of a dirt cup. The main housing defines a base conformed to self-support the main housing on a support surface with the dirt cup arranged with its open first end at a higher elevation than its closed second end. The removable dirt cup includes a handle adapted for being held by a user, and the dirt cup defines or includes a spout to facilitate emptying dirt therefrom.

摘要： A bagless canister vacuum cleaner (A) includes a selectively removable dirt cup (D), and an airstream (S) flows rotationally through the dirt cup (D) between an interior wall (31) of the dirt cup (D) and a filter assembly (F) selectively mounted in the dirt cup (D) so that entrained contaminants are separated from the airstream (S) flowing through the dirt cup (D) and collected by the dirt cup (D). The filter lies substantially parallel to the support surface on which the vacuum cleaner (A) is supported. A cover member (74) is connected to the main housing (B), and the cover member (74) is selectively movable to and held in an operative position in covering relatio n with an open first end (32) of a dirt cup (D). The main housing (B) defines a base (150) conformed to self-support the main housing (B) on a support surfa ce with the dirt cup (D) arranged with its open first end (32) at a higher elevation than is closed second end (34). The removable dirt cup (D) include s a handle (80) adapted for being held by a user, and the dirt cup (D) defines or includes a spout (58) to facilitate emptying dirt therefrom.

摘要： An upright vacuum cleaner includes an upright housing section (B) and a nozz le base section (C). A cyclonic airflow dirt and dust separating chamber is defined in the upright housing section. A suction source pulls air and entrained dirt, dust, and other contaminants through a main suction opening formed in the underside of the nozzle base section and into the cyclonic airflow chamber. The cyclonic airflow chamber (42) causes the suction airstream to travel in a cyclonic path such that the entrained contaminants are separated therefrom and deposited into a dirt container (44) that define s the chamber (42). A main filter element (K) filters residual contaminants fr om the suction airstream between the chamber and the suction source. An exhaust filter housing includes an airstream suction duct in fluid communication wit h an outlet of the airflow chamber and an inlet of the suction source (32). An outlet (36) of the suction source is in fluid communication with an exhaust plenum of the exhaust filter housing. An exhaust filter (82) is positioned radially outward of the exhaust plenum (80) such that exhaust air is forced radially outward through the exhaust filter from the exhaust plenum to ensur e that the air discharged into the atmosphere is contaminant free, including those contaminants introduced into the airstream by the suction source itsel f.

摘要： An upright carpet extractor for solution cleaning of floor and above floor surfaces has a low profile base assembly (A) including a base housing (10) and a recovery tank and nozzle assembly (18) removably mounted on the housing. The recovery tank and nozzle assembly includes a recovery tank (120, 552) for collecting recovered cleaning solution and a nozzle cover (134) which is attached to a forward portion of the recovery tank exterior to define a nozzle flowpath (138) therebetween. Working air and recovered cleaning solution are drawn through the nozzle flowpath and into the recovery tank by a motor and fan assembly. (20,534) mounted to the base housing, rearward of the recovery tank. The nozzle flowpath is removed from the base together with the recovery tank when the recovery tank is to be emptied, allowing the nozzle flowpath to be rinsed conveniently to remove trapped dirt. A carrying handle (250), pivotally mounted to the recovery tank, selectively locks the recovery tank to the housing and locks a removable lid (204) of the recovery tank to the tank to seal a discharge opening (200).

摘要： The present invention relates to an upright vacuum cleaner including a housing and a nozzle base having a main suction opening. The housing is pivotally mounted on the nozzle base. The housing comprises a cyclonic separator including a dirty air inlet and a sidewall. A lower end of the separator being secured to a lower skirt. A dust collector section is located beneath the separator and includes a sidewall. A perforated tube is disposed within the separator. The perforated tube includes a shroud extending away from a closed lower end of the perforated tube. A diameter of the shroud is larger than a diameter of the separator lower end. The lower skirt and the shroud define a first air channel for directing air from the separator into the dust collector section. The first air channel has a substantially constant volume for maintaining airflow velocity.
