No. A vacuum cleaner works by creating low air pressure inside of itself, which suck in air. That moving air can then carry small objects with it. Things sucked into a vacuum cleaner go to a bag or chamber that is then thrown out or emptied in the trash.
A black hole is an object that has completely collapsed under the force of gravity. Objects near a black hole are not suck in; they fall in due to gravity, just like what makes things fall on Earth, only much stronger. Unlike with a vacuum cleaner, which can be emptied, nothing that enters a black hole can ever leave.

What is the complete absence of matter?
No, the absence of matter would be a vacuum, which is quite different from a black hole. A regular black hole has a fairly large amount of mass (which is basically the same as matter) in a small space.
What president name is the same as that of a brand of vacuum cleaner?
Herbert Hoover and Hoover vacuum cleaners. They are not related and neither is J.Edgar Hoover.
Is a black hole known as a singularity?
No, they are not the same. A singularity would be inside a black hole.
Black holes use suction power to pull things into them?
I can't comprehend how suction would work in a vacuum :-) Black Holes' use their gravitational force to pull matter into them.
Why does a black hole have more gravity then the star it once was despite having the same or less matter?
This is a common cause of confusion. In a way, if no mass got lost in the creation of a black hole, then it will have exactly the same gravity than before. For example, if our Sun converted to a black hole (not that it is planning to do so...), our Earth would continue orbiting this black hole, in the same orbit as before. What makes a black hole different is that the mass is very concentrated; so, it is possible to get much closer to the black hole - and remember that gravity gets stronger at shorter distances.
What is the area beyond a black hole where black hole has stopped expanding and matter will no longer be pulled in?
There is no definite boundary for matter not being pulled toward a black hole. At large distances the effects of a black hole's gravity are not different from that of a different object of the same mass. How far out a black hole's gravity is dominant depends on that black hole's mass and its proximity to other massive objects.
How does one rate vacuum cleaners in Boston?
The experts in Boston rate the vacuum cleaner by first testing the product to see if it works. Then after they test the vacuum cleaner, they evaluate on how effective it picks up dirty based on quality. Then they do the same with other vacuum cleaners. After they finished testing them, they score them. The ones with the highest score gets the highest recommendation that's mostly likely to be sold in markets.
Do a Vacuum cleaner needs a magnet?
If the vacuum cleaner is powered by electricity this is used to turn the electric motor which is needed to create the suction or vacuum. That motor either has permanent magnets inside it, or the current passes through many "turns" of wire to create magnets when you switch the cleaner on. Early experiment in electricity showed that if a wire is moved in a magnetic field some current is created. Similarly, if a magnet is moved near to a wire the same result occurs. So, yes the cleaner does need a magnet.
Can the sun form a black hole and take earth to another galaxy If yes how I no why not?
No. The sun does not have enough mass to form a black hole. A black hole does not lead to another galaxy. Anything pulled into a black hole becomes part of that black hole's mass. Even then, if Earth were to fall into a black hole the same mass as the sun it would be torn apart by tidal forces long before it crossed the event horizon.
What would happen if you jumped into a Kerr black hole?
If you jumped into an "ordinary" Schwarzschild black hole, you would be crushed into a long line of particles, which means death by a black hole. If you jumped into a Kerr black hole, the same process may occur, but the only thing different is that a Kerr black hole spins, and a Schwarzschild black hole does not. That answer needs a bit more detail. Please use the "related link" below.
I am interested in a commercial vaccum cleaner dealer that can repair my Oreck XL can you help me find one?
Many vacuum cleaner dealers that sell certain brand of vacuum usually can repair the same model and brand that they sell. However, some dealers are not repair experts, so you will have to ask around.
Why is the term black hole appropriate?
The term 'black hole' is particularly appropriate in its application to the astrophysical phenomenon of the same name due to the property of the escape velocity exceeding the speed of light. This means that no light or matter escapes a black hole.
