Legee 668 Robot Mop

The Bottom Line

The Hobot Legee 668 is a robot vacuum and mop two-in-one. While the design idea is great, the execution leaves much to be desired. The Legee 668’s performance on our cleaning tests was among the worst we have tested to date (both as a vacuum and a mop). The Legee 668 would work okay as an exclusive sweeper and light dust mop. Even so, there are a number of other robot vacuums and robot mops that offer significantly better performance for less money.

Pros

  • Mop and vacuum in one robot means less work for the user
  • Good at dusting / light mopping hard floor surfaces

Cons

  • Vacuum’s performance was extremely disappointing
  • Not great for deep cleaning
  • Doesn’t work on carpet

Hobot Legee 668 Design

The Hobot Legee 668 is a robot mop and vacuum combination. While the design is similar to most other robot vacuums, there are some key differences as well.

First up, the display on top:

When you take a first look at the Legee 668, you automatically assume it is a robot vacuum. The shape, size, and general build of the unit resemble a robot vacuum.

The display on top has two buttons; stop / go, and return home. Both of these buttons are easy to understand, as they are labeled clearly on the 668.

What’s under the hood?

On the top of the Legee 668 is also a flap that opens up. Under the flap is a dustbin, which houses the filter within the Hobot Legee 668, a water reservoir, and a main power switch.

The dustbin can be removed from the robot, but the water reservoir has to be unscrewed in order to be taken out.

I’m sure you’re curious about how the bottom looks…

Once you flip the Legee 668 over, the bottom is where you will notice the biggest differences, as compared to a robot vacuum. The bottom of the unit is home to two cleaning pads, a spinning brush, two wheels, two misters, and a vacuum suction vent.

Unlike a more traditional robot vacuum, this Hobot has cleaning pads and misters that allow is to mop directly after vacuuming.

Most robot mops do not have the vacuum suction vent that this Hobot Legee does. Therefore, the differences in design on the 668 definitely separate it from the more traditional robot floor cleaners.

Accessories

The Hobot Legee 668 comes with a nice assortment of extra parts and accessories. Each of the following are included:

Filter included with the Legee 668

FILTER | One extra filter is included with the Legee 668. The filter can be used as a replacement once the original filter is no longer functioning properly.

Spinning brush included with the Legee 668

SPINNING BRUSH | Two extra spinning brushes are included with this robot mop / vacuum. The spinning brush is used to sweep dirt and debris into the cleaning path of the vacuum. The brush should be replaced when the bristles start to fan out or deteriorate.

Charger included with the Legee 668

CHARGER | The charger included with the Legee 668 should be plugged into the wall, allowing the robot to drive up to it. From there, the positive and negative ends of the charging pins will touch to the Hobot, charging it up.

Hobot Legee 668 cleaning pads

CLEANING PADS | The Hobot Legee 668 has two cleaning pads on its underside. These pads are held on to the unit by velcro and can easily be pulled off for washing and replacement. Hobot includes an extra set of these pads as well.

Remote included with the Legee 668

REMOTE | A small remote included with the Legee 668 allows users to control the unit without having to actually touch it. The remote has all of the same functions as the robot itself, but give the user a bit more control over the unit.

Water bottle included with the Legee 668

WATER BOTTLE | In order to fill up the water reservoir in the Legee 668, Hobot includes a small water bottle with a pointed tip in order to make filling the tank much easier and less messy.

Cleaning brush included with the Legee 668

CLEANING TOOL | The final accessory included is a cleaning tool. This tool has soft bristles attached to it that give users the opportunity to dust off the filter or another area of the robot, as they please.

Features

The Hobot Legee 668 is an advanced robot mop and vacuum that has some neat features.

What all does it offer?

  1.  Vacuuming – The Legee 668 has the ability to vacuum light debris off of your floor.
  2. Dry mopping – In addition to vacuuming, this Hobot can dry mop your floors. The front cleaning pad on the 668 will agitate your floor by creating a vibrating motion back and forth, lifting the dust or dirt off of your floors.
  3. Wet mopping – If you would like to use water to mop your floors, the Legee 668 can do this as well. Two small misting sprayers located on the bottom of the unit will spray water on the floor in front of the secondary mopping pad. The 668 will then drive over the water and mop it up with the same vibration method used on the dry mopping mode.
  4. Spot cleaning – If needed, the Hobot can also be placed in spot cleaning mode. This means the unit will focus on a more specific area when vacuuming and mopping.
  5. Edge cleaning – Users also have the option of having the Hobot 668 run along the edges of their walls.
  6. Automatic cleaning – The most frequently used cleaning method is the automatic mode. If users turn the Legee on and set it free without choosing a mode, the robot will vacuum and mop in a random fashion.

Cleaning Performance

Overall, the cleaning performance of the Hobot Legee 668 was a bit underwhelming.

First up, mopping tests:

To begin with, the mopping tests we put the Legee 668 up against are our standard tests. We spread mud (dirt with water), honey, and water (dyed green for visibility) across our tile floor testing lane, and give the robot an opportunity to mop each of the debris up.

For the purpose of this testing series, we decided to spead each of the debris on the lane individually, maximizing the opportunity for the Hobot 668 to perform well.

First, mud:

Our first test was the mud test. After spreading the mud across the testing lane, we set the Hobot free and watched it work. Long story short, the robot was not able to mop up all of the mud.

We allowed the unit to run until it believed the job was done and this was the result after the test:

We even ran the Hobot a second time without adding any more mud and the result was virtually identical.

Next up, honey:

The honey was by far the biggest issue for the Legee 668. Once the robot hit the honey, it got stuck in the honey and was not able to drive around our testing lane.

It seems that the way the wheels were designed on this robot limit it to less sticky substances. The honey simply grabbed the wheels and held it in one spot on our testing lane.

Additionally, the spinning brush stopped spinning because of the amount of honey it collected on its bristles. The honey stuck to the brush, which then stuck to our testing lane, resulting in a pointless brush.

Last test:

Last but not least, the water mopping test. For this test we spread 1 ounce of water across the lane and set the Legee 668 free. This test was a much greater success.

The robot was able to mop up all of the water we spread across the lane. That said, we ran the test again with 2 ounces of water and the Hobot struggled. Therefore, we came to the conclusion that the mopping pads on the bottom of the unit cannot hold much more than 1 ounce of water at a time.

I’m sure you’re curious about the vacuum tests too…

To test the vacuum cleaning features we took one ounce of rice, kitty litter, cereal, and sugar and spread them across our testing lane.

From there, we proceeded to set the robot free and turned off its mopping capabilities. This was so we could strictly test the unit’s ability to vacuum.

After letting the Hobot 668 run a full cycle, we found that the unit was not able to vacuum up more than 0.17 ounces (out of 4 ounces) of debris.

At this point, we were able to conclude that the Hobot Legee 668 is better used as a dusting mop. Extremely light debris and small spills can be cleaned up, but we would not recommend using this specific unit for much else.

Usability

On the bright side, using the Hobot Legee 668 is simple. There are a few cleaning modes available and the remote makes them easy to operate.

Before using the unit, you must set it up:

The setup for this Hobot robot is quick and painless:

  1. Unbox all parts
  2. Snap on spinning brush
  3. Fill reservoir with water
  4. Charge unit

Once you have completed the steps above, you’re ready to begin using the Legee 668.

What to expect on a daily basis:

Using the Hobot Legee 668 day-to-day is easy. Either press the button on top of the unit itself, or use the remote to select a cleaning mode.

After a mode has been selected, sit back and let the robot do the work for you. The only time you will need to be involved again is when the dust bin is full or the water reservoir is empty.

Aside from these two tasks, there is not much else required by the user.

So what about maintenance?

Maintenance is also a breeze. Change the filter and replace the spinning brush as needed. There are no daunting tasks required by the user to maintain the Hobot.

While the cleaning performance may not be top tier, the usability and maintenance of this Hobot robot mop and vacuum is extremely simple and easy to manage.

Is it a good value?

While the Hobot Legee 668 is a unique product, the value isn’t good. If you’re looking for a unit that only needs to act as a light debris sweeper and dusts more than it mops, this could be an okay option.

Legee 668 ReviewThroughout our cleaning tests, we found that the Legee 668 was not able to vacuum debris well. After placing rice, kitty litter, cereal, and sugar on our testing lane, this robot was only able to suck up a small amount of the debris, leaving quite a mess on our lane.

A similar result came about from our mopping tests. The Hobot proved that it was able to dust well, but mopping was more of a struggle overall.

With regard to usability, it’s quite easy to operate. The remote is clearly labeled and the unit is intuitive to use.

As far as maintenance is concerned, the Hobot Legee 668 does not require a ton of work. The costs are low and the workload is just as low.

All things considered, the Hobot Legee 668 is a great idea, but there are certainly flaws. The price just doesn’t make sense for the level of performance.

Who Should Buy the Hobot Legee 668 Robot?

The design concept behind the Hobot Legee as a 2-in-1 robot mop and robot vacuum on paper looks great, however, in practice it just doesn’t work. Both vacuuming and mopping performance on the Legee 668 are among the worst we have tested to date.

As a result we would not recommend the Hobot Legee 668 for the vast majority of consumers.

In our opinion, it simply makes more sense to get a standalone robot mop and standalone robot vacuum. You can get far better performance by having a dedicated robot for each cleaning chore, while also spending less money.

For example, there are a number of affordable robot vacuums (Roomba 690, Xiaowa Lite, Tenergy Otis, Ecovacs N79) that could be paired with an iRobot Braava 380t or Braava Jet 240. This combination would yield far better performance (in our opinion) and also save you money compared to the Hobot Legee 668.

If you really think the Hobot is the robot you want I would make sure you:

  1. Are okay mediocre vacuum performance – the vacuum doesn’t work on carpet at all, and doesn’t really work well on hard surfaces either. However, if you just need a light debris sweeper it could work.
  2. Are okay with a mop that’s mostly a duster – the mop cannot really deep clean as well as more traditional mops or even other robot mops. However, the larger water reservoirs does allow it to dust and light mop fairly large areas.

Summary

The Hobot Legee 668 is a robot mop and vacuum combined into one unit. By combining these two together, the Legee 668 has the ability to vacuum small amounts of dirt and debris while also mopping the floors. Although a unique combination, the Legee should not be mistaken as a replacement for either your mop of vacuum. While this Hobot can do both of these things, it does them to a much lower level than a dedicated robot completing each task on its own.

Why did the Legee 668 score the way it did?

  • Design – the design concept is there, but the execution isn’t great. Tank track style wheels don’t work as well as expected. Lack of brushroll and small size suction slot for vacuum is a major miss.
  • Performance – Vacuum cleaning performance was severely lacking across all debris types. Mop tests were passable (at best) for mud, while honey literally stopped the Hobot in its tracks. Only limited amounts of liquid could be absorbed (about 1 ounce).
  • Quality – Reasonable quality, but there is room for improvement. Some components felt cheaper than other similar robots we’ve tested.
  • Usability – Overall usability was pretty good. We liked the remote and the large water reservoir.
  • Value – The price point compared to the performance just doesn’t make sense no matter how you slice it. There are a large number of better performing and better value robots available.
