Scrape to remove inner lip of the tee with the side edge of a chisel. The inner lip of 1” tee is around 0.5mm, it's not too difficult to remove, and also can sand it down. A mask and glasses are necessary during all of the working.
Cut off 1/2" with a saw on both tee and elbow to get the extension closer to the original wand.
Tip: cut a 1/2" width paper strip and round on the tee robot vacuum cleaner and elbow to help to mark the cutting line.
Clean burrs with a file.Assemble and glue the fittings and pipes. Don't glue the coupling to the elbow yet before the wand is installed.
It depends on length of the extension and wand, if the China Handheld Vacuum Cleaners Manufacturerswant is longer, it need the space to put the wand in to the tee. I choose never glue the coupling with the elbow. Just plug connection.
Slide the wand in until it tight.
In my case, it's tight enough does not need to screw or glue on the wand. Anyhow the original wands and hose also are plugged to connect each other.
Measure the tall of the upright vacuum cleaner. This size is from experience of manufacture. It is the best length from the nozzle to the handle.
For other model vacuum cleaner, if the wand is little bit thick, recommend to try to saw the tee through to open its back so the wand can be slid in and then screw them.
