SweepScrub's used Tennant 3640 is a productive walk-behind sweeper that is easy to use for anyone in any environment including on uneven surfaces. The used Tennant 3640 walk-behind sweeper picks up anything from sand to light litter in the toughest industrial and manufacturing environments. This walk-behind sweeper is remarkably faster than sweeping by hand. The machine can be configured with an LP engine or battery and has a simple no-tool brush change. SweepScrub also stocks Tennant and Nobles replacement parts, spare parts and aftermarket parts such as brushes, filters and squeegees for used Tennant 3640 sweepers and other Tennant, Nobles, Advance, NSS and Pioneer Eclipse floor cleaning equipment.
