[HELP] Arduino Wifi Controller [URGENT]

Thanks Florinc.
Here are my details of my vacuum cleaner.
There should be 3 buttons, 1 for choosing mode (Wifi, Auto, Manual), 1 for selecting the mode, and the other 1 is for turning ON the mode.
And of course those Mode will be shown on a LCD screen.

I have done the Auto part. Now left for the Manual and Wifi.
For Wifi part, it should be controlled through the internet. For example, I am at the far distance from the vacuum cleaner and would like to turn it ON in order to help me to clean the places I want. By using the specific IP address, I could run my device.

For Manual part, it should be controlled by the laptop keyboard. For example, by pressing at the number pad, "8" for forward, "4" for left, "6" for right, "2" for backward and "5" for stop.

Anyone could help me?
Thanks a lot :~
