Code: TT1000-T-Cleanroom The TT1000-T-Cleanroom is a variant to the TT1000-T, and is especially designed to pull carts and trolleys in a clean room environment. Because of the closed clean room wheels, much less culmination of dirt occurs, and the wheels do not give off dirt. Furthermore, the electric tug consists completely of stainless steel (INOX) and can be easily thoroughly cleaned, making the TT1000-T-Cleanroom a maintenance friendly electric tug. The TT1000-T-Cleanroom is also available in two more powerful editions, the TT1500-T-Cleanroom and the TT2500-S-Cleanroom.
