- a rotary scrubber head in which the pad is circularly rotated against the floor surface
- an orbital scrubber head in which the pad is moved against the floor in an eccentric manner without completely spinning.
- cleaning fluid is conventionally discharged directly onto the floor surface in front of the advancing scrubber head. The cleaning fluid is then worked against the floor surface by the pad of the scrubber head.

A
floor scrubber 30 with anorbital scrubber head 200 for cleaning floors is shown inFIG. 1 , wherefloor scrubber 30 is an operator walk-behind type scrubber havingforward wheels 34 andrear wheels 36 for supporting movement ofscrubber 30 on a floor, as well as various tanks for providing cleaning fluid and suctioning and retaining used fluid from the floor. -
Scrubber head 200 is affixed to scrubber 30 via head arms, with only head arm 48 a shown inFIG. 1 . As discussed in detail below,head 200 includes apad 202 and a fluid applicator or applicator system 204 (FIG. 3 ), whereapplicator 204 is configured to distribute or apply cleaning fluid directly ontopad 202 rather than onto a floor surface located in front ofpad 202.Pad 202 is porous such that the fluid is retained withinpad 202, thereby providing more effective cleaning of a floor surface relative to conventional systems in which fluid is dropped or applied in front of or in advance of the head. The pads of such conventional systems tend to plow or spread the cleaning fluid, including dispersing portions to one or both sides of the pad, thereby wasting fluid and reducing cleaning. - Referring to
FIG. 2 of the disclosed embodiment,head 200 includes acover 206 having a pair ofmounting flanges 149 a, 149 b for receiving head arms 48 a, 48 b fromadjustment assembly 38, andguide wheels 208 that are mounted to cover 206 for aiding movement ofhead 200 adjacent a vertical surface.Cover 206 includes a planartop member 210, with afront member 212 and side members 214 (one shown inFIG. 2 ) depending downwardly fromtop member 210.

When either ofwheels 208 contacts a vertical surface, such as whenhead 200 is brought adjacent a wall adjacent a floor surface that is being cleaned, the force of any such impact is absorbed by being transferred to and throughcover 206 due to the mounting ofwheels 208 to cover 206. In particular, the force is transferred to head arms 48 a, 48 b from mountingflanges 149 a, 149 b and, thereby, to scrubber 30 itself. Notably, the impact force is not transferred tomounts -
Pad plate 220 has anend 228 positionedadjacent applicator 204 whereend 228 comprises a front end in the installed orientation shown inFIGS. 3-6 relative to the forward motion ofscrubber 30 when in use.Front end 228 includes afront edge 230 extending betweenside edges 232 a, 232 b ofplate 220, withfront edge 230 defining a recess orcavity 234 and a pair of extending portions that are formed astabs recess 234 extends betweentabs Front edge 230 comprises a centralfront edge portion 238,angled edge portions 240 a, 240 b and leading edge portions 242 a, 242 b, whererecess 234 is defined by centralfront edge portion 238 andangled edge portions 240 a, 240 b. As understood fromFIGS. 3, 5 and 6 ,pad 202 is mounted topad plate 202 such that afront edge 244 ofpad 202 extends beyondfront edge 230 ofpad plate 202. For example, centralfront edge portion 238 may be recessed fromfront edge 244 ofpad 202 by approximately 0.5 inches.Front edge 230 andrecess 234 thus expose a portion ofpad 202, includingupper portion 246 ofpad 202 betweentabs -
Pad plate 220 also has anend 248opposite end 228, where in the embodiment shownend 248 is substantially identical toend 228 as including anedge 250 defining a cavity orrecess 252 and extending projections 254 (one shown inFIG. 3 ). Accordingly,pad plate 220 may be installed in an opposite orientation relative to that shown in the various views such thatapplicator 204 is positionedadjacent end 248 wherebyend 248 would operate as the front end whenscrubber 30 is in use. - With reference to
FIGS. 3-7 ,applicator 204 is shown to include adistribution conduit 256 having afitting 258, wherefitting 258 is joined to a cleaning fluid delivery line (not shown) that provides cleaning fluid from a tank ofscrubber 30 toapplicator 204.Conduit 256 includes a pair of tubes orpipes fitting 258 comprising a T-fitting andtubes caps tubes elbow fitting 264 having a flaredend 266 to which the cleaning fluid delivery line is connected.Applicator 204 is connected withhead 200 by way of a pair ofclamps 268 that are affixed to cover 206 byfasteners 270. - With reference to
FIG. 4 ,conduit 256 further includes multiple nozzles ororifices 272 out of which cleaning fluid is distributed. In the illustratedembodiment orifices 272 are formed as holes in the undersides oftubes orifices 272 increasing in size from thefitting 258 towardcaps orifices 272 as the cleaning fluid travels alongtubes - As understood with reference to
FIGS. 5 and 6 ,orifices 272 are oriented such that cleaning fluid output from theorifices 272 is distributed substantially directly ontopad 202. That is, rather than discharging cleaning fluid onto the floor in advance or in front ofhead 200, cleaning fluid is caused to be directly distributed or applied ontoportion 246 ofpad 202. In the illustrated embodiment this is achieved bymounting tubes recess 234 withorifices 272 being aligned to distribute or apply cleaning fluid generally vertically downward ontoportion 246 ofpad 202. Distributing or applying the cleaning fluid ontopad 202 promotes entrainment of the fluid within theporous pad 202, with the cleaning fluid then flowing through the pad and to thepad underside 282. As such, the formation of puddles or pools of cleaning fluid on a floor are inhibited, including inhibiting the formation of such puddles that may be formed on either side of a cleaning head as the head would otherwise plow through cleaning fluid deposited on the floor in advance of a forward moving floor scrubber. - It should be appreciated that alternatively configured cleaning heads may be constructed in accordance with the present invention relative to
head 200. Including, for example, with regard to the arrangements, configurations and mounting orientation of the various members, such as the cover, pad backing plate, motor mounting plate, and applicator assembly.Scrubber 30 may also include a head adjustment assembly 38 (FIG. 1 ) for adjusting the position ofhead 200, such as disclosed in U.S. provisional patent application Ser. No. 61/709,786, to which the present application claims priority. - Changes and modifications in the specifically described embodiments can be carried out without departing from the principles of the present invention which is intended to be limited only by the scope of the appended claims, as interpreted according to the principles of patent law including the doctrine of equivalents.
