A Quick Review Of The Roomba 530 That I Should Have Bought A long Time Ago

July 11th, 2009 Greg Smith No comments

It’s hard to believe but as much effort as I have put into my home automation system I have not had an automated vacuum cleaner. I have always been skeptical of the Roomba’s ability to clean floors adequately. That mostly came from a few friends and reviews I read online.

I have been considering trying one out for myself for sometime and when woot.com had a refurbished Roomba 530 model for $129 I decided it was time give it a try.

My skepticism was unfounded. The Roomba 530 does an excellent job of cleaning my floors. I have been amazed at the amount of lint the Roomba has picked up (no more lint tumbleweeds floating across the floor). It also cleans up all the pieces of plastic and twist ties that the cat uses as toys. I am also impressed with how well it handles itself across uneven surfaces and untangles itself.

It probably helps is that my floors are all solid, no carpet or rugs and my house is pretty small. So far I have been able to have it clean the living room, kitchen, part of the hallway and bathroom in one cleaning session, or mission as the Roomba users call them. I think that the Roomba could also clean the guest bedroom across from the bathroom but so far it has some difficulty finding it’s way.

I have an automatic cat that kills all the bugs in the house and now I have an automatic vacuum that cleans up after the cat. Since the Roomba 530 model doesn’t have scheduling capabilities, I plan to purchase a serial port bluetooth module that will allow me to remotely control the Roomba from my home automation computer. The computer can keep track of how often the Roomba cleans and send it off on cleaning missions when the house is unoccupied.

Would I Fail This 4th Grade Test

Johnny Mango declares that the current APS (Albuquerque Public Schools) assessment test will be too hard. Look at the examples test questions he gives:
  • You go to a party. There are 3 drinks, 2 sandwiches, and 4 kinds of candy. How many combinations of all three are possible?
  • You have the sides of a rectangular prism flattened out. How many faces and how many total cubic inches are there?
  • You have a carpet and a runner of certain dimensions. Is the rug 3 square feet more than the runner?

These test questions or for 4th graders, do they seem like they might be over their heads? I’m not qualified to say what’s good for a 4th grader and what’s not but this seems like they are bit complicated. I even had a hard time understanding exactly what the questions are asking on the first few read through.

Albuquerque schools are in a dismal state. I;m glad to see the school district trying to improve things but this might be a bit more than the kids are ready for right now.

Click through to see if I answered them correctly.

Let’s see if I answered these questions correctly?

  1. 3×2x4 = 24
  2. This question was confusing to me. But it says a flattened rectangular prism. So at one point it was 3 dimensional which mean it has 6 faces. But since it’s flattened out it has no cu inches, otherwise they would have to give some size information.
  3. I have no freaking idea.
