Cleaning and storage station

I have different type of hard floors. Light coloured laminate floor in the kitchen, solid oak floor in the living room, hard wood in the hall and vinyl flooring in the bathroom. Over the years, I have purchased nearly all kind of cleaning equipment such as steam cleaner, electric mops, powered polishers but none dealt with the cleaning job very well so I can give up my mop. I normally spend 2 hours a week hover the floors, mop, then remove the residue water with a Kärcher window vacuum. The job is one of the chores that I hate the most.

Kärcher’s FC5 promises to wash, scrub, polish and vacuum as it goes. It sounds like a dream machine which can make floor cleaning less cumbersome and even enjoyable. Now I have been using it for 2 weeks and I am happy to report that Kärcher FC5 really is truly a fantastic piece of kit for floor cleaning.

It come nearly fully assembled. All I need to do is to slide the handle into the body and it is ready to roll. The cable is fairly long (~7 meters) and can easily cover a very large room. There is also a nice stand to keep the FC5 upright which is very handy. The stand can also be used to wet the roller prior to cleaning and wash the roller after use. Like all Kärcher product, it’s very yellow and feels very solid and well built. It’s fairly slim so takes up little floor space and is quite stable when stored between uses. When I was using a mop, it kept falling out of the bucket which was extremely annoying.

Kärcher FC5 is very straight forward to use. It’s a bit heavy (5kg with clean water tank full) but once it is going it is easy to move around and the pivoting head does make life slightly easier. The instruction says to hold onto the appliance firmly and I highly advise that you do. It has surprisingly powerful forward-drive momentum and you don’t want it to take off on its own.

On the front of the FC5 is the clean water/cleaning solution mix. A small handle releases the container to allow it to be filled up under a tap. To refit the container, simply push it back into its original position. The container is almost clear so you can see the water/cleaner solution level. The fresh water tank uses the water sparingly and so will be economical if using detergent. It can be used with clean water or any hard-floor cleaning solution made for machine cleaners. Karcher offers a range of solutions that cover all kind of floors.

On the back is the filter and dirty water tank. Emptying the tank is easy to do and you see all the dirt and bits that the FC5 has picked up.

With twin forward-rotating fleece rollers and powerful suction behind, the FC5 glides over surfaces with no effort at all. It also cleans up to edges. The rollers draw clean water from the tank and rotates to collect dust while moistening and scrubbing the floor. At the rear of the rollers, a squeegee and vacuum slot draws dirt and dirty water out of the roller’s fleece surface and into the waste tank. The ease of not vacuuming first does make a significant difference. The rotating motion can easily remove the toughest stains. Fleece on rollers do not get to dirty to continue cleaning like others do and need replacing. They almost clean themselves. If you want to, they can be easily twist off and are machine washable.

It cleans hard floors with enthusiasm, removing loose debris and even the worst dried-on stains, then buffs sealed laminates to perfection. The results are fantastic. I don’t think my floors have ever been this clean. Even after I have just cleaned my floors with mop and feel they are in a reasonable state of cleanliness, the colour of the waste water tank tells me that this have been an illusion. You will be surprised to see how much dirt a mop and bucket leaves behind.

As it does not soak the floor like a mop (only moist), any remaining surface water soon dries leaving a streak free finish. Residual water was something of concern for my sealed solid oak flooring especially in wet England winter but the FC5 doesn't leave much residual water.

Now it takes me around 30 minutes to clean the house.

Final thought

A fantastic all-round hard-floor cleaner that produce fabulous result. Highly recommended.

Cons: 

• No kickstand makes it difficult to use on lap
• SATA III rather than PCIe NVMe SSD
• No windows hello support

Technical specifications:

According to Samsung, the 2017 galaxy book has two versions, a 10 inch and a 12 inch version with various ram and storage configuration. The one featured in this article equipped with an Intel Core i5-7200U processor (seventh-generation, Kaby Lake, 2.50GHz turbo boost to 3.10GHz ), 4GB of RAM, and 128GB of storage. This on current retails on Samsung website at £1,099.00. This price includes the keyboard cover and S pen. For comparison, Surface pro with the same configuration costs £979.00 but the essential type cover will cost your £149.99. If you want the surface pen, that’s another £99.99. Add everything together, the total cost comes at £1,228.98. There is another version of the galaxy book with the same CPU but doubles the RAM and storage that retails at £1,269.00. You can also add LTE to the higher end model for an extra £170.

Design:

The Samsung Galaxy book is a beautiful piece of kit, the overall build quality and ports layout are near perfect.

The chassis is made of aluminium and is solidly built with no flex or creaks. It is razor thin and the rounded edges make it very comfortable to hold. The power and volume control keys are on the upper left of the tablet and also crafted out of aluminium which gives satisfying feedback when clicked. On the upper right you can find the CPU vent so no hot air blown to your hand. On the right-hand side there are a stereo speaker and two USB-C 3.0 ports. Each USB-C can serve as charging port that supports quick charge but neither is thunderbolt compatible so no heavy gaming using external graphic card. It would have been nice if Samsung has included a USB-C to USB-A adapter as most peripherals are still USB-A. But these are dirt cheap so no harm done. On the left-hand side sits the other stereo speaker and micro SD card slot, which needs a pin open. 

There is a 5.0MP front facing camera that doesn’t support Windows Hello. The rear facing camera is a 13.0MP shooter with autofocus but I really think the law shouldn’t allow people to take pictures with a 12inch tablet. Both cameras support 4x digital zoom.

There is no built-in kickstand so you will need to use the included keyboard stand which has 3 positions. The backlighting keyboard cover is covered with grey plastic. It’s not leather but comfortable to touch and looks good and elegant. Key travel and response are good. Typing is fairly comfortable so long time typing shouldn’t be of any issue. The function keys all carry double function such as display brightness, volume and keyboard backlight keys etc. The functions can be switched using the fn lock key or use as combo with fn key. Backlighting is three stages and works well in low-light situations.

The trackpad is pretty good as well. It's a Precision Touchpad, supporting the full range of built-in Windows touch gestures.

The magnets that hold the keyboard to the galaxy book is very strong. And you have pull really hard to remove the keyboard.

Display

If I was asked to give one reason to pick this over any other tablet/laptop on the planet, it has to be the gorgeous Super AMOLED display. The display without a doubt the star of the show here. It measures at 12 inch and has a resolution of 2160 x 1440 with the ideal 3:2 aspect ratio. It is ten-point multi-touch with glossy edge-to-edge glass. 

The super AMOLED screen on the galaxy book is simply the most stunning screen I have seen on a tablet and this is clear from the moment you press the power button. The colours are vivid with immaculate black and white contrast is immaculate, and everything just looks great. This screen is also support 10bit HDR which makes consuming media like movies movie a dream.

Pen inking

The S Pen is produced by Wacom with 4,096 levels of pressure. It feels very light in hand and doesn’t require charging. There is no place to store the pen so you have to be careful not losing it. The pen only has one button which provides a mouse-like interface. Another usefully feather is Air Command with functions like Smart Select that lets you capture areas of your screen and share them out, or create and animated GIF of an area of your screen with up to 15 seconds of recorded content. Naturally, all Microsoft functions such as Windows Ink, Sketch Pad, Screen Sketch, Sticky Notes etc. are all present and works well.  

The S Pen on the Galaxy book is very fluid and smooth.

Audio

The dual stereo speakers are at both sides of the display. The placement means they are side firing, with good fidelity and stereo separation.

Cameras

The front-facing camera is a 5MP module. It is quite bright and looks good in video – definitely sufficient for those skype calls. The rear 8MP autofocus camera is also good for a tablet camera and you can use it to snap a photo in a pinch and not cringe at the quality.

Benchmarks

I don’t really believe in benchmarks as the differences between various machines with same Intel internals are trivial and can’t really be felt in real life. In addition, modern CPUs are very capable of most of the daily tasks that we throw to them. However, with that said, I do want to show the Crystal Disk Mark Scores as I believe SSD speed is the performance bottleneck of a lot of modern PCs and can really determine the user experience. The SSD in the galaxy book is good, but not good enough. It has the SATA III interface so in that sense it’s not bad but I think Samsung really should have included a PCIe NVMe SSD unit here especially when they make SSDs found in most high end machines. In short, a SATA III SSD in a £1000 plus machine is simply not acceptable.

CrystalDiskMark (higher is better)

Device	Read	Write
Surface Pro 2017	1,284 MB/s	963 MB/s
Dell XPS 13 (9360)	1,287 MB/s	794 MB/s
HP Spectre x360 15	1,128 MB/s	862 MB/s
Galaxy book	523 MB/s	337 MB/s

Battery

The fan did come on more than I would like and was audible, though barely above a whisper with no whine or high-pitch noises. In a room with ambient noise, you shouldn’t find the fan annoying.

For battery life, Samsung claims 11 hours and I have achieved 6.5 hours using a closed-loop video test with 50% brightness and 50% volume with Wi-Fi on. Nothing ground breaking here but for such a thin machine, it’s still respectable.
