Pushing is the heaviest part of a floor washer, and the NEW400 takes it away. A self-propelled function carries the machine forward on its own, so the user guides it rather than shoving it, and a loaded tank does not turn a hallway into a workout. That one feature is why it ranks first for effort.
Its dual-tank system keeps clean water and dirty water separate, which means the floor is not rewetted with grey water and the dirty tank is the only one you need to carry to the sink. A self-cleaning system looks after the roller. Eighth cheapest of seventeen, it holds a middling position on the price ladder that keeps it reachable.
The effort that remains is emptying the dirty tank. Do it at a laundry sink or a utility tub rather than a bathroom basin so you are not bending far, and tip rather than lift the whole machine, which a lightweight build makes easy. If the tank still feels heavy, fill the clean tank only partway for a small room, since half a tank is enough for a kitchen and keeps the machine easier to guide. Many owners overfill out of habit and then wonder why the machine feels cumbersome.
