Skitter Bot came into this world as result of a chain reaction of exploded of cosmic energy. By current estimates, this chain reaction took roughly 13.7 billion years to complete. When put into such context, it becomes quite clear just how long it takes for near-perfect walking scrub brush bot to come into being.
Do not be fooled. Scrub Bot was not the simple sort of bot that materializes overnight when I zip tie a bunch of scrub brushes together. No! There was an ineffable cosmic plan that led up to this bot's creation, going back well beyond the day when man, through genetic mutation, first evolved the ability to manufacture zip ties and scrub brushes. This bot is a bona fide cosmic child.

Step 3: Attach
Next, pass them through the two adjacent center-most holes in the corner bracket.
Then, pass the zip ties through the hanging holes in the brush handle.
Finally, zip tie everything firmly together.
Step 4: Drill
Step 5: Secure
For extra support, zip tie the brush handle mounting ring to the unused back holes of the servo horn.
