Replacing Power Switch - Bob PetHair Plus

To replace Bob's power switch, you’ll need a Phillips head screwdriver, a flat head screwdriver, and a new power switch.

Before starting any repair on Bob, turn his side power switch OFF.

Then, remove his dustbin.

Flip Bob over onto a flat surface. Remove his main brush using the flat head screwdriver. Save all screws and parts for later reassembly.

Use a Phillips head screwdriver to remove the 6 screws on Bob's underside that hold him together.

Hold Bob's top and bottom together as you flip him onto his wheels. Grip Bob's cover from the back and lift up to expose his mainboard.

Slide the power inlet down and tuck it somewhere safe to avoid compressing its wires.

To detach Bob's cover completely, disconnect 4 circuit plugs:

  • 2 at the bottom of the mainboard
    • 1 on the far left
    • 1 with a thick white wire

  • 2 at the top of the mainboard
    • Disconnect the 2 center plugs

Bob's cover is now completely detached and can be set aside for the rest of the repair.

To access the power switch, you'll first need to remove the mainboard. Disconnect all remaining 12 circuit plugs from the mainboard.

Remove 3 screws from the mainboard.

Lift the mainboard out of Bob.

Slide the power switch up and out of its space located on Bob's side.

The wires feed into Bob's battery compartment. Remove the screw holding the small wire cover, then lift it up and keep aside.

Gently pull the wiring through the gap and you’ll see the circuit junction that connects the switch to Bob's battery. Pull to unplug.

Now you can slide the new power switch straight down into the space on Bob's side. Make sure the switch is turned to OFF before connecting it to the battery.

Push the circuit junction into the side of the battery compartment so it is not stuck underneath. Then, place the switch’s wiring into the small indent on the battery compartment.

Replace the wire cover and re-tighten the screw that secures it.

Align the holes on the mainboard with the 3 screw posts on Bob’s interior.

Ensure that the mainboard sits flat before replacing the 3 screws.

Now reconnect all the circuit plugs correctly.

Order of plugs on the left side of the mainboard (top to bottom):

  • Small plug with black and yellow wires
  • Plug with two pairs of twisted wires
  • Plug with multi-colored wires
  • Small plug with blue and black wires

Order of plugs at the top of the mainboard (left to right):

  • Small plug with red and green wires 
  • Wide plug with multi-colored wires
  • Two empty spaces for now
  • Small plug with black and orange wires

Order of plugs on the right side of the mainboard (top to bottom):

  • Wide plug for Bob’s power switch
  • Plug with black and orange wires for Bob’s power inlet

For now, the bottom of the mainboard will have two open spaces on the very left.

Then, the order from left to right is:

  • Small plug with a red wire
  • One more open space
  • Small plug with yellow wires
  • Plug with multi-colored wires

Now you’re ready to begin re-attaching the cover.

Reattach all 4 circuit plugs connecting Bob's cover to the mainboard:

  • 2 at the top of the mainboard

  • 2 at the bottom of the mainboard

Remember to slide the power inlet back into its space on Bob's cover.

Align the cover’s edges precisely. Ensure that no wires are compressed in the main brush compartment or visible at the edges of the bumper. If so, take a step back and lift the cover to tuck the wires into the appropriate spaces inside Bob.

Then, flip Bob over onto a flat surface. Replace all 6 screws previously removed from Bob's underside.

Replace the main brush and dustbin before your next use and Bob is completely reassembled!
