The combination of pure water, the Unger indoor pad holder (JRC, Detroit Sponge, et al) the euro to Unger pole adapter the white scrub pad and Gardiner over the top rinse bar with the 100 degree black jets (Detroit Sponge) or build your own over the top rinse… is a force to be reckoned with in pure water cleaning. It has the synergy of the Wagtail dual action pivot, the scrubbing power of the white pads and the genius of the over the top rinse bar.
The 10x 4.5x 1" pads from (Detroit Sponge) work great on this tool. The 9x6x1/4" pads trimmed also work great.
To increase scrubbing power of the pads just reduce the contact footprint of the pad to the glass. With these new holes… now we can have a larger or wider footprint and still retain enough scrubbing power for dirty windows.
Now with the holes in the pad… we should be able to double the surface area of the Unger doodlebug by connecting two pad holders together with some kind of wishbone arm above the two pads.
There is a dual pivot doodlebug with an acme thread that is available from (Detroit Sponge). The great thing with this lessor expensive tool is it can be trimmed or narrowed down to give more scrubbing power.
These doodlebug pad setups, some low cost pure water filters, a back pack sprayer, a water hose to a john guest 8mm pole hose connector, some Gardiner pole hose and some aluminium poles and maybe the 12, 15 and 18" Wave and your gona be in business. (The Waves require the hook side of industrial Velcro strips to hold the white pads (Wal-Mart)).
