20" ALL-ROUNDER Brush is designed specifically for maximum coverage on commercial glass, and for maximum stability when using Water Fed at extreme heights.
Whilst the 24" has more coverage, the 20" brush has less jets, so if you are not certain that you have enough water pressure to clean above 60FT, this is the better option.
20" ALL-ROUNDER is modified to use RHINO HI-FLO TUBE - ensuring the least resistance, maximum flow possible. If you are using a DELIVERY PUMP, please use at least 1.5gpm, and no more than 2.5gpm. The pressure rating is not so relevant, but 100PSI is ideal.
RHINO-HI-FLO can fit snugly in TUBE-RUNNER, or, if you are old-school, a loop around the pole every 6ft is also effective to ensure the weight of the tube and water is held to the pole structure.
