If you have been looking for a vacuum cleaner that takes care of the chore of vacuuming for you, then you should read more about the iRobot Roomba 770 vacuum cleaning robot for Pets and allergies. This little machine is a pretty powerful device that can remove as much as 98% of dirt and debris and tough pet hair from a variety of surfaces in your home.

The iRobot Roomba 770 vacuum cleaner is simple to set up out of the box. All you will need to do is remove the unit from the box and set it up together with its charger before you use it for the first time. It is a good idea to set the unit up in an out of the way location under an end table or a couch so that you will not see it when it is inactive and charging. You may think that your home is really clean, but you will be surprised to see how much dirt is collected in the Roomba 770’s dirt cup at the end of a cleaning cycle.

This vacuum is slim and can get into out of the way places under furniture that a person would need to get down on their hands and knees to reach. The Roomba 770 has a variety of features that help to keep your home clean. The dual HEPA air filter does not allow fine dust to re-enter the air in your home. This unit features two virtual walls so that you can prevent the Roomba 770 from going down any stairs or any other area where you do not want it to enter.

Once it is switched on, the Roomba 770 will navigate from room to room in a variety of patterns and will collect the dirt and debris from the floor. Once the dust bin is full, the Roomba 770 will let you know that it needs to be emptied so you do not have to guess. It is best to turn the unit on after you have set up your virtual walls and watch the machine in action to observe any potential obstacles or other problems that may occur when the unit is in operation in your absence.

Pros of the Roomba 770
Cleans your home when you are not home so you do not have to listen to the noise or do the work yourself. It is done for you when you arrive home.
Returns to home base to recharge itself once the work is complete or if it senses that it does not have enough charge to complete the task at hand. Talk about a smart Vacuum!
Runs for about 2 hours on a single charge.
Is able to transition between floor levels to move easily from carpet to tile or wood and clean all equally well.

Cons of the Roomba 770

Does not have a physical manual available but you can view it on your computer. This might be problematic if you need an immediate answer, but you could print the manual so that it is available when you need it in the future.
May frighten pets if they are not introduced to it properly.
Small dirt transfer line may be visible from unit routinely bumping into walls and leaving dirt behind, but this can be easily rectified by dusting it off the wall.
Cord of your other electronic equipment and children’s toys, lying on the floor can be a hindrance to the Roomba 770 to move about. But you can remove or move items to clear a path for the unit to clean more thoroughly.

10000mAh Mi Power Bank 2 Review

A few weeks back, Xiaomi launched its next generation power banks in India. These power banks come in 10,000 mAh and 20,000 mAh battery capacities. I tested the 10000mAh Mi Power Bank 2 that is available for Rs. 1199 in India. This is 10000mAh Mi Power Bank 2 Review.


Like its predecessor, this power bank (like GOAL ZERO YETI 400 ) also carries aluminum but it is sleek and looks very premium. Look how beautiful this power bank is and I am in love with this glossy black look. At the top edge, it has 4 LED’s that will indicate the battery level. I am sure you know how to interpret it. It also has a button to check battery level and enter in low-power mode. It also has one full USB port and one micro USB port.

With curved edges on two sides, it offers decent grip. The size is smaller than a 5.5-inch display smartphone, so you can easily carry it in the pocket. Length is 130 mm and width is 71 mm. The weight is around 230g.
Safety Features

Mi Power Bank 2 comes with lots of safety features including.
Temperature Resistance
Reset Mechanism
Protection from Short Circuit
Input Overvoltage Protection
Protection from Output Overcurrent
Protection from Incorrect Insertion
Protection from Overcharge and Over-discharge
Output Overvoltage Protection
PTC Protective Circuits for the Cell


It is compatible with 5V/2A, 9V/ 2A, and 12V/1.5A charging. This power bank has 10,000 mAh battery capacity and could charge my Zenfone 3 two times. When you connect it with a phone, it automatically starts charging the phone. It turns off 30 seconds after the device is not detected.

The most notable feature of this power bank is the ability to charge lower power devices. Just double press the power button to enter low power charging mode. This mode will be activated for next 2 hours. Low powered devices take less than 2 hours to charge. So, this time is fine enough.

The best thing about this power bank is that it supports fast charging. It supports fast charging in both ways. So it charges your phone faster and you can also charge this power bank faster. Charging time depends on your wall adapter you are using to charge this. With a fast charger, it takes around 6 hours in charging. With 18W charger, it takes just 3.5 hours in complete charge. With normal charger, it will take longer time.

I couldn’t face any heating issue while charging or discharging.

Final Words

I am very impressed with this Power bank’s design and performance. The dual fast charging makes this power bank different than other power banks available in the same price segment. You can get good power banks with better battery capacity, but fast charging is something that saves lots of time.

If you want to check more power banks, see the list of best power banks under Rs. 1000 and best power banks under Rs. 1500.

Rooftop concentrating photovoltaics win big over silicon in outdoor testing

UNIVERSITY PARK, Pa. — A concentrating photovoltaic system with embedded microtracking can produce over 50 percent more energy per day than standard silicon solar cells (for example: GOAL ZERO SWITCH 10 MULTI-TOOL KIT ) in a head-to-head competition, according to a team of engineers who field tested a prototype unit over two sunny days last fall.

"Solar cells used to be expensive, but now they're getting really cheap," said Chris Giebink, Charles K. Etner Assistant Professor of Electrical Engineering, Penn State. "As a result, the solar cell is no longer the dominant cost of the energy it produces. The majority of the cost increasingly lies in everything else — the inverter, installation labor, permitting fees, etc. — all the stuff we used to neglect."

This changing economic landscape has put a premium on high efficiency. In contrast to silicon solar panels, which currently dominate the market at 15 to 20 percent efficiency, concentrating photovoltaics focus sunlight onto smaller, but much more efficient solar cells like those used on satellites, to enable overall efficiencies of 35 to 40 percent. Current CPV systems are large — the size of billboards — and have to rotate to track the sun during the day. These systems work well in open fields with abundant space and lots of direct sun.

"What we're trying to do is create a high-efficiency CPV system in the form factor of a traditional silicon solar panel," said Giebink.

To do this, the researchers embed tiny multi-junction solar cells, roughly half a millimeter square, into a sheet of glass that slides between a pair of plastic lenslet arrays. The whole arrangement is about two centimeters thick and tracking is done by sliding the sheet of solar cells laterally between the lenslet array while the panel remains fixed on the roof. An entire day's worth of tracking requires about one centimeter of movement, which is practically imperceptible.

"Our goal in these recent experiments was to demonstrate the technical feasibility of such a system," said Giebink. "We put together a prototype with a single microcell and a pair of lenses that concentrated sunlight more than 600 times, took it outdoors and had it automatically track the sun over the course of an entire day."

Because the team needed to know exactly how much direct and diffuse sunlight there was during the test, they set up at the Russell E. Larson Agricultural Research Center at Penn State where there is a National Oceanic and Atmospheric Administration Surface Radiation monitoring site. Graduate students Jared Price and Alex Grede worked together with post-doctoral researcher Baomin Wang to test the system over two sunny days from dawn to dusk right alongside a commercial silicon solar cell.

The researchers report today (July 17) in Nature Energy, that the CPV system reached 30 percent efficiency, in contrast to the 17 percent efficiency of the silicon cell. All together over the entire day, the CPV system produced 54 percent more energy than the silicon and could have reached 73 percent if microcell heating from the intense sunlight were avoided.

According to Giebink, this embedded tracking CPV technology would be perfect for places with lots of direct sunlight, such as the southwestern U.S. or Australia.

Giebink notes that major challenges still lie ahead in scaling the system to larger areas and proving that it can operate reliably over the long term, but he remains optimistic.

"With the right engineering, we're looking at a step-change in efficiency that could be useful in applications ranging from rooftops to electric vehicles — really anywhere it's important to generate a lot of solar power from a limited area."

Other researchers working on this research from Penn State are Jared Price and Alex Grede, graduate students in electrical engineering, and Baomin Wang, postdoctoral scholar in electrical engineering, all first authors; Michael Lipski, undergraduate student in electrical engineering; and Chris Rahn, professor, Greg Brulo, graduate student, and Xiaokun Ma, graduate student, all in mechanical engineering.

Researchers from other institutions include Brent Fisher and Scott Burroughs, Semprius Inc.; Kyu-Tae Lee and John A. Rogers, Department of Materials Science and Engineering; and Junwen He and Ralph G. Nuzzo, Department of Chemistry, all at University of Illinois at Urbana-Champaign.

How Local SEO Agencies Came up?

Well done search engine optimization, frequently called Search Engine Optimization for short, was created to permit sites to appear in search results when people search for services and products rather than just company names. The point is the fact that folks trying to find stuff online can locate a company website with no prior knowledge of the company or its name. There are all manner of tricks and techniques which fall under Search Engine Optimization, but the great sustainable systems (also sometimes called "white hat Search Engine Optimization") are based throughout the concept of creating your site easier for search engine to read and comprehend, meaning they rank you higher in searches for suitably related terms.

It isn't unusual to determine to outsource Search Engine Optimization to external advertising services as well as other firms, however, there are quite a few dodgy sorts out there who want to take firms seeking Search Engine Optimization - particularly local and little businesses - to get a very costly ride. How then does one really go about getting a great, sincere and valid internet search engine marketer?

It's in fact very simple to locate a decent Search Engine Optimization service online. Visit an internet search engine such as Google or Bing and type in "Search Engine Optimization service." Blowing off the paid advertisements on top, whichever company has landed on top of the search results are that which you need - they must be quite good at Search Engine Optimization or their very own website would not be so high in the natural listings!

To narrow things down a bit, you can try widening your search. Say you reside in Essex and desire a nearby bureau - simply type in "Search Engine Optimization service, Essex." Or in case your website is specialized and you also need specific help with it. It is possible to add your business or site kind - "Search Engine Optimization tourism" or "SEO eCommerce" for example. This is often an excellent solution to seek out market local SEO agencies that have specialist expertise in your discipline.

Occasionally Search Engine Optimization services (or at least individuals promising to be Search Engine Optimization services) attempt to solicit businesses by sending them e-mails or submitting contact forms with various enticements and offers. Yet in case you see something such as this come in then it's best to disregard it - if a firm which allegedly specialises in internet search engine optimisation is reduced to spamming inboxes to get business rather than, say, doing Search Engine Optimization so their particular site ranks highly and individuals can locate them anyhow, odds are they aren't really great. Exactly the same holds true of Search Engine Optimization services advertised on paid advertising on top of search engines or on banner ads on different sites. If their search promotion is any great, why are they having to fund their placements?

Yet another thing to remember will be to steer well clear of any Search Engine Optimization service that assures you "leading place for x keywords" or something similar. Almost all modern search engines used personalized searching, meaning that everyone sees sites in somewhat different position places contingent upon their personal search history. Complete positions certainly are a matter of yesteryear, any anyone promising to deliver this form of service is lying through their teeth. Modern Search Engine Optimization will use sustainable "white hat" techniques to be able to bring useful visitors to your own site, not use exploits and dodgy tricks, that'll always get them smacked by internet search engine upgrades like Google's notorious Panda and Penguin algorithm changes.

When you have found a Search Engine Optimization firm that searches mainly all right you will have to ask them some questions before you jump to their services. Together with the normal tests like present customer list and testimonials, this is a superb thought to talk to somebody directly on the telephone or in person. Here are a few great questions to ask them.

Who does their search advertising work? Is it handled by in-house staff? Do they do any outsourcing, particularly to foreign firms? Plenty of services outsources to low-cost link contractors in Asia who have a tendency to generate quite low-quality work that may get an adverse effect on sites in the medium to long term.
How frequently do they report, and what format do these reports require? Any professional Search Engine Optimization bureau needs to be providing regular updates to any or all its customers, as well as written reports detailing actions,  were taken and progress made.
What sort of abilities and qualifications do they have? Have a look at their present customer lists for just about any recognizable huge names, and see whenever they've anyone who's Analytics qualified. A number of businesses even use quality standards like ISO 9001 that's a superb sign.
What else do they do? Lots of those businesses are mainly web site designers that are resellers for outsourced Search Engine Optimization services to enhance their profits. It's more straightforward to try to find an internet marketing specialist to make certain you get a high-quality service.
In the event you do not have the cash to hire a professional Search Engine Optimization service there are other alternatives available. Some businesses allow you to pay for a one-off website review to make recommendations on the best way to enhance your website from an internet search marketing perspective, or you also may study present techniques and concepts to do Search Engine Optimization for yourself.

This is why everyone should be careful about making this decision otherwise one can be easily mistaken and make the mistake over and over again. For more information use Google or any other search engine system as it will be easier to find a solution to the problem if you try to do a little research by yourself.

Many website marketing strategies are in fact startlingly straightforward. Raise your domain name power by getting other related websites to link back to yours. Get backlinks increase together with general advertising advantage through the use of social websites like Facebook. Keep your website full of frequently upgraded and top quality content to motivate individuals to link to you personally at the same time as growing the website 's visibility and value. Work with a good, solid Search Engine Optimization plugin on your content management system, and ensure that your site 's code is error free.

Recall you will get an all-natural increase from modern search engines in case your internet site is

Nicely designed, simple to use and pleasant to look at
Full of great, current and useful content intended for actual people, not search engine robots
Free of malfunctions, quickly loading and devoid of spammy advertising or buggy code
Joyful website promotion, everyone!

Why Social Media Marketing Isn’t Always the Answer for Small Business

Social media marketing gets a lot of attention in the business world. With Facebook expanding to over a billion users and Pinterest traffic growing and growing it is easy to believe that all marketing is online these days. This is just not true.

When thinking about other forms of marketing to promote a business, it’s a good idea to consider what type of marketing suits the business best. Where are the potential customers hanging out? What do they read? What do they look at? Where do their interests lie? Position the business in the right locations and it doesn’t have to be too expensive once one gets creative.

Here are some ideas on how to use forms of marketing other than social media to promote a business:

Billboard Advertising

Advertising via an existing network of billboards doesn’t have to be as expensive as one would think. It is often possible to advertise on a single billboard in a location that is ideal to pick up local people going to work and coming home from work later on.

Traffic patterns and other considerations can be used to better target the billboards to select and the type of advertising that will be most effective for the local audience.
