We were starting to have some issues where the suction hose was bending in and not working on our tennant scrubber. Replacement was easy and we saw a huge difference in suction just changing out the hose. When turning right the machine presses on the hose and overtime it weakens it. This fixed that and the machine runs much better. Only note is that the end in a little longer on this hose vs the original one, but there was no functional difference, I just noticed because I had them side by side when replacing. Make sure to have a zip tie when doing the replacement.
