How can I increase the suction power of my cordless vacuum broom?

Click For Summary

Discussion Overview

The discussion revolves around the suction power of a cordless vacuum broom, focusing on the mechanics of suction, potential modifications to the device, and the implications of such changes. Participants explore the design and functionality of the vacuum, as well as the feasibility of enhancing its performance.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions how suction works and considers increasing the amperage or voltage to improve performance.
  • Another participant cautions against exceeding the design specifications for voltage and amperage, citing potential dangers and reduced motor lifespan.
  • A different participant suggests that the vacuum's design may inherently limit its efficiency, noting that achieving high suction pressure is challenging.
  • A follow-up question is raised about whether increased airflow to the motor would enhance suction capability.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility and safety of modifying the vacuum's electrical specifications. There is no consensus on the best approach to improve suction power, and the discussion remains unresolved regarding the effectiveness of increasing airflow.

Contextual Notes

Participants mention potential limitations related to the design and manufacturing tolerances of the vacuum, which may affect the ability to modify it successfully.

I was wondering about the how the suction works? I got this cordless vacuum broom for free and it has terrible suction. It runs on like 7 or 8 recharge c battery's and I was wondering if i increased the amperage or voltage would the motor run faster and have more suction?

I would not recommend increasing the volts/amps past the design specs, this will likely cause the motor to have a reduced lifetime, and may actually be dangerous to you (electrocution, motor catching fire / bursting).

In terms of how these work, many of them are turbine based - i.e. a radial turbine. But there are many many variations as you can imagine.

In general I would say that you won't be able to fix it yourself. The parts may be very tight tolerance that you can't replicate without CNC machines.

The clue is probably in the word "free". Designing and building an efficent compressor isn't easy. Probably the best you can hope for is that it produces a fairly high volume of air flow, not a high suction pressure with the inlet blocked.
 
So increased air flow to the motor should increase the suction of the vacuum?
