vacuum motor

[electricano]

i have an idea to build an automnous vacuum cleaner but i dont now where to start with.
most important is what type of motor i need to use?the vacuum will be battery-operated.what is the minimum rpm for the motor in order to create powerful suction?

is there any website providing this type of info?i knew that there is a vacuum robot called roomba but it is too small for me. my vacuum cleaner will be used outdoor.

plz give me some suggestion.

The RPM required to develop the suction is dependent on the rotating wheel (fan rotor). You might start by looking at commercially available vacuum cleaners and going from there.

The motor i got from a batery powerd vacum cleaner spind at extreme RPM(and power)

PS:
It had a weel that loced somting like a turbines weel(i think it works on G force)

where u got the motor?

The commercial vacuum cleaner motor RPM is 20000...22000.Most of battery operated v.c. contains same motors as minidrills (Johnson or Mabuchi) the RPM is 18000.
