swirlgirl need help to clarify doubt about: : Is a 800w vacuum cleaner more powerful than a 6ampere one?
My mom is trying to choose a vacuum cleaner. She asked me about comparing the two cleaners that I mentioned in my question. Trouble is, I know that watts = amperes (volts), but I still don’t know how to answer her question. Can you help?

800 W is more powerful than 6 amp, regardless of whether you’re using US voltage (115 V) or European (230 V). W (Watts) is a measure of power and A (amps) is a measure of current. Power = amps times volts. So, if you live in the US, 6 amps means 6 A X115 V = 690 W. It’s not a huge difference, so price and features are more important considerations.
Add your own answer in the comments!
In physics we compare add or subtract physical quantities of the same nature. Each electrical device has a label on which you find the tension it requires and the power it delivers. So you compare in the case of a multiple choice the power of the different products. In that case it is better to look for the vacuum the cleaner produces.
If your voltage is 115 that gives 690 watts.[USA]
At 120 volts its 720 watts{USA}
If you are in the UK your voltage is 230 so that is 1380 watts.
So the answer depends on your voltage and whether you are in the UK or USA.
Your house voltage should be 115 v -120 volts. House voltage varies and is never a constant.
So
I = P/V = 800/120 = 6.7 amps
The 800 watt vac draws 6.7 amps and is only slightly more powerful.
I would look at the price and features and then make the decision because the two are about the same in terms of amperage
