Taking the iRobot Roomba 560 Robot Vacuum for a Spin

Friday, April 3rd, 2009

Most people, by now, are familiar with the iRobot Roomba. It’s a small robot that vacuums your floor on its own. It’s a concept that brings us a step closer to the robot maids of the movies. Finally, we can have an army of robots whirring around the house cleaning up after us without a care in the world.

Well, almost.

iRobot Roomba 560

The best way to really get to know and love (or not love) a Roomba is to have one running around your house for a week, but for those without that option, I’ll try to bring you into the experience with me. My wife and I borrowed one from iRobot for a couple weeks and here’s what we learned.

What it does for you
In short, it’s a robot vacuum that makes its way around your floors, cleaning up any dirt it finds along the way. While it can just randomly run around picking up dirt, it can be set to move in a spiral pattern, which could be optimal in terms of efficiency, depending on your scenario. It also comes with two lighthouses to keep it from wandering into rooms you’d rather it avoided. These aren’t needed to keep it from going off the stairs, though. Although I don’t have stairs in my own home, I asked some friends about their 560 and they assured me that it indeed won’t go bouncing down the stairs.

iRobot Roomba 560 - beconGetting a Roomba to clean is easier than getting me to clean, because it only had to be told once after giving it a full charge. I just touched the Clean button on the top and it started cleaning. This little guy can clean up carpet or hard floors, adjusting its brushes accordingly and has a bumper to let it gently realize physical boundaries. However, a bumper just means it will retry in another direction and keep retrying if it keeps hitting a wall or object. It did seem smart enough to get going in the right direction pretty quickly. It also returns itself to it’s home base when it’s done or you tell it to dock for charging. Not all models include the scheduling feature, but the 560 does. This feature is ideal for a household with hours of downtime while everyone is at work, like mine. Initially, I was worried that a Roomba would be a big threat to a house full of cats, but they did OK with it. One of them tried to eat the poor little Roomba and the other two just cautiously got used to it.

I’ve discovered another model series called the Pet Series, which this 560 is not a part of. The Pet Series promises a deeper cleaning to grab all that pet hair my cats leave all over the place. Unfortunately, not being a part of that series, the 560 had to make many passes to get things really clean. I don’t vacuum once a day or even once a week, and the Roomba works best when it’s allowed to run frequently. This seems like a downside at first, but it’s really the ideal way to keep your floors clean all the time. After I let him run for a couple days, he seemed to do much better.

What you still have to do
The Roomba is a cleaning robot, but it can’t clean itself. The folks at iRobot have made cleaning pretty easy, but you still have to do it pretty often to keep him running smoothly. When I talk about cleaning, I mean not only the obvious dumping of the removable tray, but also the more arduous cleaning of the brushes and under a couple parts.

Before using the Roomba, it’s probably a good idea to pick up a little, too. With an upright vacuum, you can sometimes be lazy and just work around an ottoman or other objects on the floor, but the the idea is to be even lazier with the Roomba. Pick up some things before he starts his shift and you can relax until he’s done.

Using the Roomba
Using the Roomba was really simple. Even without a manual, it would have been pretty easy to figure out that you press the clean button and it cleans. When button throbs orange, it means he’s running low on energy and red means he’s in desperate need of a charge. Just hit the Dock button and he aligns himself with his charging base and heads home. At first, it looked like he was going the wrong way, but he needs to get a couple feet away first to line up properly.

Don’t force him. With a little patience, he’ll get the job done and get home just fine.

Some pros and cons
Let’s start with the obvious advantage to having a robot vacuum… less work for you. If the Roomba does all the vacuuming, you can come home to nice clean floors every day. One of the things I almost overlooked when writing this is the fact that it’s cordless. There’s something to be said for not having to constantly move around an electrical cord to the vacuum to avoid running over it.

Conclusions
At a reasonable price, this is a great alternative to pushing around an upright vacuum. If you don’t clean often, the Roomba might create more work for you, having to clean the tray pretty often, but you’ll have a cleaner floor. If you vacuum a lot, the Roomba will save you a lot of energy. Just schedule it to do its work while you’re at work and empty the tray when you get home or before bed. The 90 seconds it takes to empty the tray is a worthwhile daily routine for a constantly clean home. If I hadn’t already just spent a lot of money on another unnamed upright, I’d have bought this for half the price.

WowWee’s Tri-Bot is a Perfect Mix of Mobility and Character

Thursday, March 12th, 2009

Since the release of the original Robosapien, WowWee has been well known for making cool robots that won’t cost an arm and a leg. Always working on new robots to entertain kids and adults alike, they came out with the Tri-Bot some time ago and they put one in my hands last week to review.

A fun design
Whenever I buy a robot that you expect to act like a robot, I’m of the opinion that it should look the part. I think WowWee has accomplished this with the Tri-Bot. He certainly looks like a robot, but he also looks like a fun robot. His eyes and grin are always wide, hinting at his excitement, his face in general makes me think he’s about to tell a joke, and he’s bright red, which is a bold step away from the white, grey and other subtle colors normally found on robots.

His three-wheel design is also a nice switch, too, apart from being functional. It’s another reminder that while he has personality, he’s still a robot and can zip around pretty quickly. On the back, he bears a large handle which seems a bit out of place like when you see those over-sized spoilers on little suped-up cars. Maybe that’s the point, or maybe it’s just because it’s really handy, but that was the only visual aspect of this little guy I didn’t find appealing.

Programming, mobility and accelerometer-base controls
The first thing you notice about Tri-Bot is his three big omniwheels. An omniwheel is a wheel that includes smaller wheels around its edges that are perpendicular to the larger wheel’s rolling direction. This gives Tri-Bot a lot more directional mobility than any other wheeled robot I’ve experienced. I hate that these wheels are a magnet for carpet lint and cat hair, but they operate well on carpet, wood, and tile, so it’s a fair trade-off.

Another new feature is the remote, itself. It makes good use of an internal accelerometer. If you’ve ever seen how a Wii remote works, this is nothing new… except that it’s in a robot’s remote control. Like any other accelerometer-controlled device, it takes some practice. To move Tri-Bot forward, you just lean the remote forward while holding the trigger on the bottom and to make him back up, lean it back. Leaning the remote to either side makes him move sideways in that direction. It’s about time we see this is a recreational robot, and the timing is perfect with all the iPhone games that work in the same way.

For those not yet comfortable with this new-fangled control system, this remote still has the expected front/back/left/right directional buttons as well as buttons in between those to accommodate forward-right, left-reverse and similar diagonal movements. The omniwheels allow him to spin around, too, so they’ve thrown in a couple spin buttons. He spins fast, too. So fast, that it’s a little hard to be precise with it. Above the cluster of directional buttons is the HOME button. When the HOME button is pressed, Tri-Bot searches for his beacon (the remote) and will try to return to it, which seems to work pretty well. Below the directional buttons are the program record and playback buttons which let you, you guessed it, record and play back a series of movements. Following those is the little brain button. Really, that’s his roaming button. When you press it, you’re telling Tri-Bot to wander around on his own, exploring and making comments.

The bottom half of the remote has four buttons: DEMO, GAME, GUARD, and ALARM. The DEMO button should be pretty obvious. It tells him to perform a demonstration for you, which you can see in the video below. The GAME button lets you enter game mode and choose a game. The GUARD button activates his guard mode, which mostly meant he sat there waiting for something to happen and the ALARM button activates his alarm mode and allows you to set his alarm. The alarm mode (also demonstrated in the video below) is a neat idea, but I don’t know when I would realistically use it. The reason for this is that you can set the alarm to go off anywhere from one to twelve minutes after setting it, but not more. When it goes off, Tri-Bot runs around randomly, flashing and making all kinds of noise. If Tri-Bot had a little digital clock and I could set the alarm for an actual time, it would be a great feature. All three games are driving games where you have to complete a series of navigational actions to complete a game and are good for getting real practice moving Tri-Bot around.

Before reading my final thoughts on this little guy, take a look at the video below of him in action. You can also see the full photo set here.

The final verdict
While my Robosapien 2 is still my favorite, the Tri-Bot comes packed with everything a toy robot should. It’s designed to be appealing to any age group, gets around quickly, is funny, smart, and seems pretty durable. Aside from the alarm, Tri-Bot is a near-flawless, well thought out winner, smartly priced around $50. As an adult, I get more excited about things like web-based control over wi-fi and a built in camera, but for any child, this would be the gift that could help re-validate your “World’s Greatest _____” mug in that child’s eyes.
