Long Exposure Robotic Vacuum Art

iRobot Roomba Long Exposure

(Updated January 30, 2012: Added the Dirt Devil.) I finally got the time, equipment, and software together to make long exposure photos of the different floor cleaning robots to look at the differences between the three. So, above is a long exposure of an iRobot Roomba cleaning up the “hall” in my house. It’s about eight feet long and maybe 5 feet wide. There is a furnace return in the upper left corner that the Roomba avoids, thinking it’s a cliff.

Here you can see the orderly progression of how a Neato Robotics XV-11 cleans an area this small. It does the perimeter, and then precisely vacuums the area inside. You can’t tell from the photo, but the line in the middle is actually from two paths. One going from left to right, and the other from right to left.

Mint Cleaner Long Exposure

This is my favorite of the bunch. The Evolution Mint Cleaner goes back and forth, and then does the perimeter, but much more meticulously than the Neato robot. So it leaves quite a bumpy trail around the room.

The Dirt Devil RoomMate runs around a room pretty much like a Roomba does, with alternating behaviors. It does random bouncing around, spirals, and wall following. In a small area like this, it spends a lot more time doing wall following than anything else. Like all the rest of the robots, it’s not a big fan of the furnace return.

Here’s a photo with the lights on, following a Neato XV-11 through the room again. It took a different way to do it this time, going up and down instead of back and forth.

Did I mention that I made these photos with an Olloclip fisheye lens? I don’t usually talk about things other than robots on this blog, but this thing is really cool. It’s a three-in-one add-on lens for the iPhone 4. It has a fish-eye lens, a wide angle lens, and a crazy macro lens. Here are some other photos I’ve taken recently.

12 Reasons Why Mint Cleaner is Better than the Scooba 230

Mint vs Scooba

Trying to decide between buying the new Scooba 230 and the Evolution Mint? We can help. I was going to write a long article comparing the Mint Robot Cleaner with the iRobot Scooba 230, but the results with the Scooba 230 were kind of unfavorable – see our review. So instead of a Mint vs Scooba post like I did with the Roomba, I decided to make a list of reasons why a person would want to get an Evolution Mint instead. Here they are:

1) The Mint is less work, part 1. The Mint also sweeps as it mops, so it picks up hairs and dirt as it goes. Before running the Scooba 230, you have to sweep first, and even then it will find and deposit hairs around the floor. For me, I would find myself using the Mint to sweep up before running the Scooba, which made me wonder why I even bothered with the second robot.

2) The Mint cleans our bathroom in under seven minutes. The Scooba takes 45 minutes.

3) The Mint can clean more space on one charge. After finishing the bathroom, the Mint is ready to take on three more rooms (about 600 square feet). The Scooba needs to be charged.

4) The Mint cleans silently. In addition to the vacuum noise, the Scooba emits an annoying squeaking noise.

5) Mint works smart, not hard. The Mint maps a room as it goes, and gets every bit of the floor. iRobot fans will doubtlessly debate the relevancy of this topic, but you really need to see how the Mint cleans. It methodically goes back and forth over the whole floor, and then does the perimeters.

6) The Mint comes with everything you need to get started in the box. With the iRobot Scooba, you have to buy a bottle of the cleaning solution and some batteries. Sure the Scooba comes with four soap packets, but that’s only good for four cleanings.

7) Clean floors. According to our informal testing, the Evolution Mint does a better job of cleaning.

8) Clean floors, part 2: The Scooba 230 left a lot of water on the floor, and after the floor dried, a lot of streaks.

9) The Scooba is more work, part 2: When the Mint is done, you grab it by its handle, take off the cleaning pad, put the cleaning pad in the wash, and put the robot away. When the Scooba finishes, you have to open all the ports, rinse it out thoroughly (which means filling it up, closing the holes, shaking it, and then pouring it out several times – which you have to do with both sides), pull the bottom off and rinse the hairs and debris off of it, put the bottom back on, and then you can put it away.

Mint is Shorter

10) The Mint is shorter. It’s only by about 1/2 inch, but even that difference makes the Mint fit under more furniture.

11) Dual membership has its benefits. In addition to mopping, the Mint is also built to sweep. The Scooba just mops.

12) More for your dollar. The Mint is 1/3 less expensive than the Scooba 230.

Tips for using Mint Cleaner for Mopping

Here’s a quick tip on using the Mint as a mop: Before running the robot, pour or flick a little warm water on any dirty or sticky spots on your floor.
