>> announcer: the following is a paid advertisement for the all-new shark rocket powerhead brought to you by shark/ninja. vacuums designed to have more power are built bigger, heavier, and more difficult to maneuver. >> my other vacuum was huge and bulky. >> it doesn't go, like, under the sofas and the couches and the chairs. >> announcer: and those light, compact vacuums are convenient, but don't come close to giving you real cleaning performance. >> my other vacuum didn't have enough power. >> i have to go over the same surfaces two and three and four times. >> announcer: traditionally, in order to provide deep-cleaning power with powerful suction, vacuums were made large and heavy because, until now, powerful has meant big. but hold on, because shark is about to take the impossible and make it possible. shark has done it again! introducing the high-powered, super-light shark rocket

breakthrough that delivers huge deep-cleaning power... >> it has more suction than any vacuum i've ever used. >> with the powerhead, as small and compact as it is, it still it blew me away. >> announcer: in a no-loss-of-suction upright that weighs only one pound in your hand as you use it... >> i cannot believe how light it is. i can get really close to my furniture, and i can just do it one-handed. >> announcer: ...with effortless maneuverability... >> the powerhead was so easy to maneuver. it was just a flick of the wrist that i was able to go around furniture >> announcer: ...and offers a radically new way to complete-clean your hard floors. >> the powerhead has the gentle brush that dusts the floor and has enough power to get it clean. i love it. it is fantastic. >> announcer: so, how did shark create a vacuum so incredibly powerful and yet so light and convenient? they started with one of their most powerful full-size uprights and brought all of that incredible deep-cleaning power

creating a deep-cleaning vacuum that is shockingly lightweight in your hand and exceptionally maneuverable. there is simply no comparison to today. on carpets, the shark rocket powerhead brings tremendous suction together with a deep-cleaning brush roll to pull out the ground-in dirt buried deep within the fibers, every time you use it. on delicate bare floors, the shark powerhead is extraordinary. many other vacuums that recommend turning off the brush roll leave you with suction alone. but suction alone isn't enough to remove that stuck-on layer of dust, so your floors are left looking dull and dingy. but the shark powerhead gives you both incredible suction plus direct floor engagement with a unique gentle-touch hard-floor brush roll, removing that stuck-on layer of fine dirt to give your floors a true complete clean. on hard wood, suction alone leaves that dusty layer behind, but not the powerhead. on tile, suction alone can't do

it all and makes it shine. >> with the softer brush that comes with the shark powerhead, it just sweeps up that real fine dust and makes a nice, polished-looking floor. >> the gentle brush roll is great at polishing up after it pulls up all of the hair and dirt, which was amazing. >> announcer: and the powerhead solves a problem that stops other vacuums in their tracks -- furniture. but the sleek and agile powerhead goes wherever the dirt is without moving the furniture. i've never been able to get under this table with a vacuum. this is perfect. >> announcer: the powerhead is more than just muscle. it's super lightweight and so easy to carry. but its breakthrough design will amaze you because you only feel one pound of weight-in-hand when you use it. this thing is a breeze. there's no effort. it goes by itself. >> announcer: for pet owners everywhere, the shark rocket powerhead is a dream come true. >> the powerhead is the absolute perfect vacuum for people who have pets. i have a long-haired golden retriever. with the powerhead, i can go

quickly, and it sucks all the hair up. >> i can get in those nooks and crannies and really get out all that pet hair that's lurking everywhere. [ chuckles ] >> announcer: the powerhead pulls so much dirt up from carpets and up from the floors. to empty the dust cup, you just pop, lift, and empty. it's like no other vacuum you've ever used before. compared to dyson's latest cinetic, both have no loss of suction, both have deep carpet cleaning, but only the new shark powerhead gives you one pound weight-in-hand at a third of the cost. shark c.e.o. mark rosen is so sure you'll love the powerhead, he's going to do something shark has never done before. when you purchase the powerhead, mark is going to give you an additional shark vacuum, free! everyone is familiar with shark's top-rated lift-away vacuums that retail for up to $350. they offer incredible portable cleaning performance. now you can have that same portable, above-floor cleaning

$350, because when you order the powerhead, you're going to receive the shark rocket lift-around, free! there is simply no easier way to clean above the floor and throughout your home -- bookshelves, furniture, shutters, drapes, perfect for the car. and the lift-around is yours to keep even if you return the powerhead. the powerhead is the first and only of its kind. it's the most powerful, deep-cleaning, no-loss-of-suction vacuum with only one pound weight-in-hand convenience. >> i literally am doing the whole house in half the time it took me before. >> announcer: prove it to yourself by taking the shark powerhead 60-day challenge. if you don't agree it's the most powerful, lightweight, best-cleaning vacuum ever, then shark wants you to send it back for a full refund. they'll even pay the return shipping, no questions asked. >> i don't think i could go back to another vacuum. >> the powerhead is definitely the best vacuum that i've ever had. >> i'll never go back.

it because it's so great. >> hi. i'm amy motta, and i'm here with the c.e.o. of shark, mark rosen. and mark, i know you've got a big announcement to make, so let's just get right to it. >> amy, you know that we've spent the past few years in what i'll call a friendly rivalry with dyson, and i'm proud to say that now, compared to dyson, twice as many americans choose shark vacuums. >> mark, that's huge news. congratulations! >> here is the original shark rotator professional. it's been one of our best-selling, five-star-rated uprights. but i challenged my engineers to take all the incredible shark technology and magic that went into creating this, and put that winning shark mojo into something really compact and lightweight. now, take a look at the new shark rocket powerhead! look at this! it weighs only about nine pounds! it's amazing! >> i cannot believe how light it

>> this is awesome. >> it was so light but so powerful. >> this has got to be the lightest weight vacuum with the most power that i've ever experienced. >> now, check out this mess. there's sand, there's potting soil, there's crackers, but look at what happens when the shark powerhead meets this challenge. look at that. >> wow! >> look how wonderful this is able to deep-clean your carpets. >> this is unbelievable. >> i'm amazed. >> i was shocked at the amount of power. >> to have that much power coming out of such a small product is an engineering marvel. and it's so maneuverable. >> let's talk about maneuverability. the powerhead has only one pound weight-in-hand when you use it. can you believe that? look how easily i can maneuverer the vacuum. look how easily i can get underneath furniture. this is simple. >> it looks so easy to use. >> we call this dynamic power steering.

phenomenal. >> one flick of the wrist will get me into any little corner that i need to. >> it's so easy to get around into the places where i need to go without having to move all the furniture. >> announcer: to prove that the lightweight and compact shark rocket powerhead can pick up what other vacuums leave behind, we asked people to first vacuum with their own bigger, heavier uprights on their own carpets. these folks did the same thorough job vacuuming they normally do, and they were completely satisfied with the results. but then we asked them to try the rocket powerhead for the first time and vacuum the same area. once they tapped the lever and removed the dust cup, well, they just couldn't believe how much dirt the powerhead was still able to pull out of the very same carpets they just vacuumed with their current vacuum. >> oh, my gosh. this weighs nothing, and it still was able to get all of that. >> i would have never imagined that we would be able to pick up this much dirt in this area,

so, i'm just shocked. i'm shocked and embarrassed. [ chuckles ] >> okay. >> now first, have you ever seen anything like this? >> no, i haven't. >> it's a brush-roll garage, and it makes cleaning or changing your brush roll so simple. look how easy it is to pop out >> nice. but wait. there's something different about this brush roll. >> this is our exclusive gentle-touch hard-floor brush roll. this is going to change hard-floor cleaning forever. other vacuum brands advise you to turn off the brush roll when you're doing hardwood floors, so you're left with suction only. but suction alone doesn't get all the dust. there are actually two layers of dirt on your floors -- the top loose layer of debris and that stubborn, stuck-on layer of fine dust. suction can pick up the loose, larger particles, but it can't

dust, so your floors are left dull and dingy. but look at the powerhead handle that same mess. its gentle-touch hard-floor brush roll keeps turning. you have incredible suction pulling up the larger, loose dirt and the direct engagement of those soft filaments that buff away that thin layer of stuck-on dust to give you a complete clean. just take another look at this. which do you want for your home? >> the really nice thing about the powerhead, in addition to picking up all the particles and the hair, it also dusts the floor and gives it a very polished look. >> i don't have to worry about the powerhead scratching the floors with the soft bristles. it's vacuuming and dusting the floors at the same time, which i love. >> with the shark rocket powerhead, we've created something really special -- a lightweight, compact vacuum for everyday use that is designed to truly deep-clean carpets and complete-clean all your hardwood floors.

perfect vacuum. it's small, it's lightweight, it's easy to move, but at the same time, it has incredible suction power and incredible cleaning power. i don't think i could go back to another vacuum. >> i am a true believer. i was a little skeptical in the beginning. i said, "how can something so lightweight and so small and so compact be that good?" and i was pleasantly surprised. it's the most amazing product i've ever had. >> announcer: introducing the ground-breaking shark rocket powerhead -- the most powerful, deep-cleaning, no-loss-of-suction vacuum with only one pound weight-in-hand convenience. pure cleaning power plus effortless maneuverability -- the powerhead features shark's exclusive dynamic power steering. with just the flick of your wrist, you can go around, in between, and under furniture with ease. on carpets, the powerhead brings tremendous suction together with a deep-cleaning brush roll to pull out the ground-in dirt buried deep within the fibers.

all of the furniture. and so, it's really easy to clean up the pet hair. >> amy, we developed an ingenious brush roll that allows you to clean your bare floors in a whole new way. we call it the gentle-touch hard-floor brush roll. you see, traditional vacuums use suction alone on hard floors, and while suction picks up loose debris, it can leave behind a stubborn layer of dust and dirt. with the gentle-touch hard-floor brush roll, we combined incredible suction with gentle agitation that allows you to pick up not only the loose debris, but the stuck-on fine dust as well. this is something that no other vacuum has. the shark engineers put together the brush-roll garage. that means no belts, no screws, and the brush roll pops out that easily. now, look over here. i've got the gentle-touch brush roll, and just as easily as the

one pops in, and you're done. let me show you this in action. >> okay. >> this is a great demonstration of hard-floor cleaning. look, see that? we've got some loose dust on top, but underneath we have some stuck-on dust. look at this. >> oh. >> now i want to show you how well the shark powerhead cleans compared to this dyson cinetic. >> okay. >> now, don't forget to shut off the brush roll, because dyson explains that on delicate floors, you got to shut off the brush roll. >> shutting it off. all right. >> all right. here we go. >> here we go. >> look at this, amy. my gentle-touch hard-floor brush roll means you can leave the brush roll on even on delicate surfaces. and look at the powerhead. it's not just getting the top loose layer. it gets it all. >> okay, mine still looks a little dusty, like it just got the surface. >> exactly. you were able to pick up that surface dirt while i picked up everything.

>> yeah, yours is very shiny. >> when you're using the gentle brush roll in the powerhead, it does a great job of not only picking up those particles that are on there, but it's almost like buffing a car. >> when i use the powerhead with the brush roll, i don't have to worry about scratching the floors because all it does is clean the floors and give them a good dusting at the same time. >> announcer: introducing the ground-breaking shark rocket powerhead -- the most powerful, deep-cleaning, no-loss-of-suction vacuum with only one pound weight-in-hand convenience. call or go online right now and the new shark rocket powerhead can be yours for only five payments of $39.95. you'll also receive the one-of-a-kind gentle-touch hard-floor brush roll and the brush-roll caddy. be one of the first 500 to order and you'll receive your shark rocket powerhead with free shipping. with your order, shark will also include their famous five-year v.i.p. service guarantee. if anything goes wrong in the

money laundering is big business. states is no different. criminals turning ill-gotten gains into assets that appear legitimate, they do it by hiring attorneys to set up a maze offshore accounts. how easy it is, steve croft found out for "60 minutes." evidence than changing skyline of new york city where much of the pricey real estate is being

but by anonymous shell companies with secret owners. there is nothing illegal as long as money is legitimate. no way to tell if you don't know who the real buyers are. one of the reasons global witness, london based nonprofit organization that exposed international corruption came to new york city 19 months ago. it wanted to see how helpful u.s. lawyers would be in concealing questionable funds. this hidden camera footage was shot in law firms across manhattan, without the lawyer's knowledge. by the man in the gray coat with the german accent. >> it's ralph? >> ralph kaiser. not his real name. an investigator for global witness, posing as representative of a government official from a poor west african country who wants to move millions of dollars into suspicious fund into the united states. he need the lawyer's help. >> tell me what country?

it is one of those -- mineral rich countries in west africa. >> attorney gerald ross and other lawyers were told seek res was essential because the the african minister had amassed his fortune collecting special payments from foreign companies he helped obtain valuable mineral rights. so companies are eager to get ahold of minerals. >> yes. >> so they pay some special money for it. kaiser said it was all legal. he told attorney james silkenaught that the minister was shopping for a townhouse, a jet and a yacht. but his name must not be connected to the purchases. >> if his name now would appear real estate here and other items, it would look at least very, very embarrassing. >> right. presumably his salary and,

the kind of acquisitions? >> sure, the salary of a teacher here. how can we make sure that he is being able to buy property here? and to live a nice life but his name being out? >> right. any guesses as to how much money we are talking about, for the brownstone and other items? >> for the brownstone, $10 million. for second hand gulf stream, $10 million, $20 million. a yacht would be at least $2 million, $3 million. >> reporter: the fictitious story of the minister was cooked up in global witness's london office based on a money laundering case. the investigator phoned 50 law firms with experience in private asset protection and got face to face meetings with 16 lawyers in 13 firms. >> i would say, gray money.

>> reporter: global witness says the pitch was designed to to raise red flags and to give the lawyers good reason to suspect that the minister's millions came from official corruption. and they all did. >> i told you the money is a bit tainted. >> tainted. >> pretty much. >> okay. >> you gave another expression. so i have to be frank. how would you name it? >> some people call it bribes. >> no, not bribes. business deals. okay, bribe. bribe. >> the story, the african minister would have raised eyebrows for the average person on the street. >> co-founder of global witness, public advocacy group that exposes. corruption in the developing world. previous undercover investigations, exposed the african blood diamond.

exposes flaws in the u.s. legal system that made it a hub for international money laundering. >> what the lawyers laid out for us in some detail was all the different possibilities and ways in which it could be done. >> reporter: if you want to get dirty money into the united states it is not that hard to do. >> i am saying there is an open door. and pretty shocking and pretty concerning. because, that money could be coming from anywhere. >> reporter: of the 16 lawyers that global witness recorded in the preliminary meetings, only attorney, jeffrey herman flatly declined to participate and showed ralph kaiser the door. >> i have some real questions about that -- under the foreign corrupt practices. >> right. >> under the foreign corrupt practices act, bribing foreign officials is illegal. >> by americans. >> by americans.

involved? so it is money from others, not american entities. >> it's not -- >> aside from one exception. 12 of 13 law firms, including 15 of 16 lawyers, not only heard kaiser out, they suggested ways that the suspicious fund could be moved into the u.s. without compromising the minister's identity. attorney james silkenaught was select by global witness. at the time he was president of american bar association. he and his colleague, provided what prosecutors said was a road map using layers of interconnected shell companies in multiple jurisdictions. >> presumably, set up a little bit of series of owners to tripe to have protect, privacy as much

>> yeah. >> company a owned by b, c, d. and your party owns -- all of the majority of the shares of cc and d. >> create several companies all in new york? >> at some point. probably pretty quickly you go offshore. >> reporter: attorney john jankoff and partner, recommended variations of the same strategy. >> lot of people in africa use the isle of mann, some use liechtenstein, and just take his millions of dollars put it into a swiss bank account. swiss will have it. and then -- he comes to us. >> the attorney also suggested the minister could move his money out of west africa to europe where it could be scrubbed in anonymous corporate

his name? >> it is different names. so it will come as -- different names. >> including his name. >> we have to scrub it at the location. >> how you do this? that means the bank in liechtenstein, luxembourg? >> we'll set up an appropriate called it clientoverseas.com. whatever. that will send money into the united states. >> reporter: if that was a banker talking instead of a lawyer. he could be in serious trouble. that's because under u.s. law, bankers are required to report suspicious financial activity to the authorities. lawyers are under no such legal

banks in america are required to be cognizant of risk and report on it if there is an issue, or money laundering. yet, absolutely bizarrely american lawyers aren't. this is clearly an issue. i think our investigation has shown the potential for what could happen. because of that lack of regulation. >> reporter: global witness says that anomaly is one of the flaws in the u.s. legal system that helps facilitate money laundering. >> another is the ease with which anonymous shell companies can be set up here to conceal ownership of money and assets. last year, 2 million new corporations were set up in the united states, many with no offices, products, or employees. bank account. >> the in many states across america you need less identification to open an anonymous company than a library guard. >> anonymous shell come pans are get away cars for crooks. designed to put them as far away as possible from the scene of

according to a world bank study, the u.s. was the favorite place to set up anonymous shell companies. >> there was a good academic study and the u.s. was easiest place to set up after kenya. >> did the study have anything to do with your decision to do these undercover investigations? >> it inspired us. we thought it can't be this bad, can it? what we found was it is. >> we'll have part two of steve croft's story, tomorrow. or you can see the full report on our website. cbsnews.com. the overnight news will be right back. music introducing new k-y touch gel cr me. for massage and intimacy. every touch, gently intensified. a little touch is all it takes.
