  • the surface cleaner 10 is operable in the upright cleaning mode when the canister assembly 28 is coupled to the body 12 and the second end of the hose 44 is coupled directly to the base 20 in fluid communication with the nozzle 24.
  • the surface cleaner 10 is operable in the auxiliary cleaning mode when the canister assembly 28 is removed from the body 12, and the second end of the hose 44 is coupled directly to the base 20.
  • debris and fluid are vacuumed into the nozzle 24, through the hose 40, and into the recovery tank 36.
  • the recovery tank 36 is configured to contain the debris and/or fluid collected from the cleaning surface.
  • the upright cleaning mode enables the user to use the surface cleaner 10 in a familiar manner, similar to a traditional upright hard floor cleaner or upright extractor.
  • the canister assembly 28 is coupled to the body 12 and the base 20 is moved across the surface by the handle 22.
  • the auxiliary cleaning mode illustrated in Fig. 2 provides a different cleaning experience than in the upright cleaning mode.
  • the canister assembly 28 is removed and the second end 44 of the hose is still coupled to the base 20. This allows the user to use the handle 22 to guide the base 20 along the cleaning surface in the same manner as the upright cleaning mode.
  • the body 12 has a lower profile as well as a lighter weight. This lower profile operates similar to a traditional canister cleaner allowing the surface cleaner 10 to reach hard-to-reach areas, such as under a couch or a coffee table.
  • the surface cleaner 10 is operable in the lift-off cleaning mode when the canister assembly 28 is removed from the body 12 and the hose 40 is uncoupled from the base 20.
  • the nozzle 24 is configured to be removed from the base 20 and the second end 44 of the hose is coupled directly to the nozzle 24.
  • the lift-off cleaning mode allows the user to operate the surface cleaner 10 for spot-cleaning or above-floor cleaning.
  • the surface cleaner 10 may include an accessory cleaning tool 70 connectable to the second end 44 of the hose 40 in the lift-off cleaning mode.
  • the cleaning tool 70 includes a fluid distributor 50'.
  • the fluid distributor 50' is in fluid communication with the supply tank 34 through the fluid line 54', and the fluid distributor 50' is configured to provide a cleaning fluid to the cleaning surface.
  • the fluid line 54' extends along the hose 40. Fluid flows from the supply tank 34, through the fluid line 54', to the cleaning tool 70 and out the fluid distributor 50' to the cleaning surface.
  • the cleaning tool 70 includes an actuator 56 in fluid communication with the supply tank 34, fluid line 54', and the fluid distributor 50'.
  • the fluid distributor 50' is activated by the actuator 56, such as a user-graspable trigger.
  • the cleaning tool 70 is connectable to the second end of the hose 44 to fluidly connect the cleaning tool nozzle 52', 52" to the hose 40 and the cleaning tool fluid distributor 50' to the fluid line 54'.
  • the hose 40 is configured to be uncoupled from the base 20 while the canister assembly 28 is coupled to the body 12, and the second end 44 of the hose 40 connectable to the cleaning tool 70 for above-floor cleaning.
  • hose 40 connecting directly to the base 20 or the cleaning tool 70 is that the hose 40 creates a shorter and more direct airpath to recover debris and fluid from the cleaning surface. Secondly, it allows different constructions of the body 12 that allow a more compact and space efficient surface cleaner 10.
  • the body 12 is a collapsible such that the lower portion 14 and the upper portion 16 are adjacent in a collapsed position. This may be accomplished by having the upper portion 16 and lower portion 14 of the body 12 telescope together. Because there is no airflow to consider in the body 12, the construction of the telescopic body is simplified. In one embodiment, not shown, the body 12 is collapsible by folding, such that the upper portion 16 and handle 22 are folded to be adjacent to the lower portion 14 at a joint. The collapsibility of the body 12 reduces the size of the surface cleaner 10 for storage.
  • the surface cleaner 10 may also include an agitator 26 operatively positioned to engage the cleaning surface.
  • the agitator 26 is driven by an agitator motor 64.
  • the agitator 26 is configured to agitate the cleaning surface in both the upright cleaning mode and the auxiliary cleaning mode.
  • the agitator 26 is operatively positioned in the base 20.
  • the agitator 26 is operable in the upright cleaning mode and the auxiliary cleaning mode.
  • the cleaning tool 70 of Fig. 6 includes suction through the nozzle 52 to draw debris and fluid, but does not include a rotatable agitation feature.
  • the cleaning tool 70 includes bristles to enable manual agitation of the surface.
  • the surface cleaner 10 is powered by household electricity connected by a power cord 65 to the canister assembly 28.
  • Alternating current (AC) is supplied to the suction motor 32 by the cord 65 to power the suction motor 32 and controls of the surface cleaner 10.
  • the cord 65 powers the suction motor 32 when the canister assembly 28 is both coupled to ( Fig. 1 ) and uncoupled from ( Fig. 2 ) the body 12.
  • a power cord runs along or in the hose 40 to supply power from the canister assembly 28 via the power cord 65 to the agitator motor 64.
  • the base 20' includes a battery 62 that powers the agitator motor 64 when the canister assembly 28 is uncoupled ( Fig. 7 ) from the body 12'.
  • the battery 62 is rechargeable.
  • the body 12' includes electrical contacts 67 and the canister assembly 28 includes corresponding electrical contacts that mate with the electrical contacts 67 of the body 12' when the canister assembly 28 is coupled to the body 12'.
  • power is supplied from the cord 65 to the canister assembly 28 and to the battery 62 via the contacts 67 to recharge the battery.
  • the agitator motor 64 is a direct current (DC) motor and the surface cleaner 10' includes an AC to DC converter.
  • the agitator motor 64 is powered by the battery 62 when the canister assembly 28 is both uncoupled from and coupled to the body 12'. In such an embodiment, the battery 62 is charged when the canister assembly 28 is coupled to the body 12'.
