So my Scooba 450 died with the pump not working. Pulled it apart and sure enough the pump seals were not only ripped, they were bad. Apparently this was a really crappy design and has ended the life of many Scoobas.
After staring at it for awhile, I realized it “Ain’t gonna lick itself” and decided it was time to repair it once and for all.
So, I did. The way they have the pump set up is that the hose that the pump works on is not really good. It tends to go flat and stick together which pretty much kills the priming function. This would be an easy fix with a new 1/4 hose, but the bigger problem is they used an absolutely crappy sealing system to connect the pump to the scooba pipes. It’s junky silicone, it leaks, and worst of all it rips apart when you try to remove the pump. Then you’re dead.
Solution is this: Pull the plumbing on the pump, put a new longer 1/4 food grade line in, and route the line right to the scooba’s plumbing. It doesn’t quite fit, but a little force can make wonders work….
Some pictures (note: this forum doesn’t display high detail images well. Posting the links).
The space you have to work with is minimal but there
Putting in and plumbing the pump. Yaay, it fits without kinks.
Well, sort of. Have to put the blower exhaust stack back in….
Looks like it’s routed well enough. Now to see if it works tomorrow once I charge up the battery…..
