I've found a vacuum in my utility room. Since I almost never use it, I thought it was a good idea to see how it works... So let's go!!

-
The 4.8 Rowenta vacuum can be used for a variety of purposes.
-
It is charged through its pedestal. The power of the pedestal is:
-
Input: 230V - 50 Hz - 7W (AC)
-
Output: 7.5V - 300 mA (DC)
-
-
-
This vacuum has several parts:
-
The tip
-
The reservoir which holds the dust and debris
-
The engine (4.8V)
-
The pedestal
-
The power supply
-
From top to bottom, the reservoir contains 3 parts: the housing, container, and filter.
-
-
-
Remove the two outer Philips #00 screws from the bottom of the engine.
-
The back of the circuit board will now be visible.
-
-
-
Remove the two inner screws.
-
Insert a flat screwdriver between the cover and the base of the engine and remove the cover.
-
-
-
-
The wires of the vacuum are now visible.

-
The wires of the vacuum are now visible.
-
The wires connect the charger light, switch,engine, and power wires.
-
The green box labels the engine.
-
The orange box labels one of the four batteries (4*1.2V)
-
-
-
The top of the circuit board contains components including capacitors, resistors, wires, and a chip.
-
The bottom side shows the tracks that connect the components.
-
-
-
Remove the screw securing the handle with a screwdriver.
-
Open the handle to see the inside using the flat screwdriver.
I removed the handle top and I found it to be quite difficult. I needed to use a plastic pry tool to pull the handle cover a bit to the outside (left and right) because there are some plastic holders that grab the handle. These plastic holder are placed two on each side and one at the end of the handle top. Force was required for the removal.
After this the body can be separated by pulling and pressing on the middle to detach the white plastic holders.

-
This is the pedestal that will be torn down.
-
-
-
At the bottom of the pedestal, remove the 4 rubber pieces.
-
Remove screws using a screwdriver.
-
-
-
Lift the plastic piece carefully from the bottom of the pedestal.
-
-
-
Inside the pedestal, the power cable separates into 2 wires. Each wire is connected to a conductive piece.
-
This completes the vacum cleaner teardown

This could use some discussion of how to replace the rechargeable batteries used in portable vacuum cleaners.
