(Mini) Handheld vacuum cleaner with a pet hair brush

Posted in Bagless vacuum cleaner, Feature, Handheld vacuum cleaners | 0 Comments

Due to its limited performance, cordless handheld vacuum will never 100% replace the standard vacuum cleaner but as a second vac in the household (weighing under 1 kg) it is ideal mainly for cleaning the kitchen sideboard, plug sockets or bookcase. Usually, the handheld vacs are not equipped with motorized brush but Shark SV736 is something completely different. Mini vac from shark

iRobot 560 Roomba Vacuuming Robot, Black and Silver

Posted in Bagless vacuum cleaner, Robotic vacuum cleaners | 0 Comments

PROs:new, improved navigation, much better cleaning coverage and vacuum pickup than before, omproved particle filtration;
CONs: robot will never clean better than a human, but who cares if that human is you…

Three-stage cleaning

This smart, powerful, and autonomous vacuum features iRobot’s proven and patented three-stage cleaning system.
First, innovative spinning side brushes grab dirt and debris from corners and along wall edges, then two high-speed, counter-rotating brushes pick up pet hair, food crumbs, and other debris.
The powerful vacuum sucks up the debris and deposits it into a large, easy-to-empty bagless dust bin.

Automatically adjusting cleaning head

The improved fine-filtration system traps dust, pollen, and other allergens inside the robot, reducing infiltration into your living environment. The cleaning head automatically adjusts to transition from wood, tile, and linoleum to carpets and rugs.
Improved anti-tangle technology ensures it won’t get stuck on cords and rug fringe. If Roomba begins to pick up a cord or carpet tassel, it will automatically reverse the direction of its brushes to extract the item.

Sixth sense vacuuming… and when hungry, goes back home!

Roomba senses dirtier areas and spends more time cleaning them, and it uses built-in cliff sensors to avoid stairs and other drop-offs. When the job is done, Roomba returns to its self-charging Home Base to dock and recharge between cleaning cycles or when the battery is running low.

Roomba tells you when it needs maintenance

The Roomba 560 features a friendly and informative audio voice demonstration that walks you through initial setup and alerts you when Roomba requires maintenance or assistance. Starting a cleaning cycle is simple–just press the “Clean” button and Roomba does the rest. First it will calculate the size of the room, the obstacles in the room, and the cleanliness of the floors. Then it goes to work all by itself. At the end of each cleaning cycle, the Roomba 560 returns to its Home Base to dock and recharge. Yes, it’s that simple. Routine maintenance is a snap. The large-capacity bagless bin is easy to slide out, empty, and click back into place. The brushes and filters can be easily removed by hand for routine cleaning and maintenance.

Features

  • A powerful vacuum: Two counter-rotating brushes and a powerful vacuum remove dirt, dust, pet hair, and other debris from your carpets and floors
  • Robot intelligence: Navigates throughout your home, cleaning under and around furniture, covering each area an average of four times
  • Avoids off-limit areas: Virtual Walls tell Roomba where to clean by restricting off-limit areas
  • Efficient room-to-room cleaning: Lighthouses ensure thorough completion of one room before vacuuming the next
  • Self-charging and docking: Automatically returns to its Home Base to dock and recharge between cleanings
  • Detects dirt: Senses dirtier areas and spends more time cleaning them
  • Cleans beneath furniture: Cleans under tables, beds, chairs, and other hard-to-reach places
  • Edge-cleaning capability: Follows wall edges and reaches deep into corners to remove dust, dirt, and debris
  • Self-adjusting cleaning head: Automatically adjusts from carpets to hard floors and back again
  • Light-touch bumpers: Roomba slowly approaches obstacles, gently touches them, then redirects to clean around them
  • Anti-tangle system: Roomba effectively extracts itself if it picks up cords, carpet fringe, or tassels
  • Simple operation: Roomba keeps itself charged and ready to go–simply press the Clean button and Roomba does the rest
  • What’s in the box: 1 iRobot Roomba 560, 2 Virtual Wall Lighthouses (each requires 2 C batteries, not included), 1 self-charging Home Base, 1 power supply (3-hour charge time), 1 brush cleaning tool, 1 rechargeable battery, 1 extra filter

Vacuum cleaning time calculation

Roomba 560 calculates the appropriate cleaning time and pattern for each room and adjusts its behavior over 67 times per second to achieve the most thorough cleaning result. On average, Roomba covers every part of the floor four times! A gentle-touch bumper system senses obstacles so Roomba automatically slows its approach, gently touches the obstacle, then redirects to continue cleaning under or around the object. Because it cleans under furniture, Roomba actually vacuums more of the floor than a standard upright can–and you don’t even have to push it around.

Give a good ship a lighthouse (or two)

Two Virtual Wall Lighthouses ensure the most efficient room-to-room cleaning. Set each to Lighthouse mode to ensure that Roomba cleans one room in its entirely before moving on to the next. Set it to Virtual Wall mode to create an infrared beam at door openings and other off-limit areas that Roomba will not cross.

A super fast charging capability

The vacuum’s advanced power system consists of a fast-charging battery, a three-hour charger, and a power source that supercharges the unit for up to 120 minutes of continuous cleaning, covering about three to four average-size rooms on a single charge. When the battery is low or when Roomba has completed a cleaning cycle, it automatically returns to the self-charging Home Base to dock and recharge.

As a member of the newest generation of Roomba innovations, Roomba 560 features a more powerful vacuum and redesigned high-speed, counter-rotating brushes that pick up more dirt, pet hair, dander, cat litter, crumbs, leaves, and other debris.

Dyson DC07 All-Floors Cyclone Upright Vacuum Cleaner

Posted in Bagless vacuum cleaner, Upright vacuum cleaners | 0 Comments

PROs: 270 air watts of suction power, not bad for a 12A american standard, 17 feet hose plus 35 feet power cord and of course the 5 years of warranty…
CONs: a bagless vac will never provide such filtration as a bagged one. Simply, the bag (3-5 layers of paper) represents an additional filter…

Dirt doesn’t stand a chance. Using Dyson Root Cyclone(tm) technology, this vacuum doesn’t lose suction, effortlessly destroying dirt with abandon. Safe on all floor types, the brush control system cleans and protects delicate rugs and floors, trapping dirt in its easy-empty bag-free chamber. Dyson DC07 is pictured in yellow. Five-year limited warranty.

Designed by engineering guru James Dyson, inventor of the cyclonic vacuum, the 12-amp Dyson DC07 upright is an inspired combination of power and structural smarts. At the center of the machine’s innovation is the Cyclone air path design, an eight-section chamber that creates powerful, consistent suction. The conical chambers generate 100,000 g of centrifugal force, pushing dust and dirt out of the airflow into the vacuum’s 1-gallon collection cup. With no bag to clog, the vacuum’s 270 air watts of suction remain steady. The large, transparent collection cup is easy to check and empties tidily–pop it off, hold it over a trash bin, and pull the trigger to release dirt without having to touch it. The DC07 also comes equipped with a multipart filtration system to improve overall air quality in the home. The HEPA filter, measuring 412 square inches in surface area, traps microscopic particulates and allergens. Expertly built, the filter is designed to last the lifetime of the machine. Furthermore, Dyson upright vacuums are the first and only vacuums certified asthma friendly by the Asthma and Allergy Foundation.

Suitable for bare floors and carpets, the Dyson upright features a 14-inch cleaning path and edge-cleaning bristles. A simple foot pedal switches off the brush roll for bare floors, and the nozzle automatically adjusts for changes in carpet height. The vacuum is equipped for above-floor cleaning with a cleverly stowed, quick-release 17-foot hose with a reversible, extension-wand handle. Onboard accessories include a crevice tool, a dusting brush, and an upholstery attachment, all designed to function without “sticking” to surfaces. Made from the same material used in crash helmets, the vacuum is unquestionably durable. Plus, the design only puts 4 pounds of weight on the handle, so pushing and turning is easy. This model comes with a 35-foot power cord and a five -year warranty. Emily Bedard (of Amazon)

The most efficient vacuum cleaner in the world?

Posted in Choosing the best vacuum cleaner | 0 Comments

The most efficient (in terms of the ratio of suction power/energy consumption) vacuum cleaner I have ever seen is the Panasonic MC-CG675JC79.

It features 1200W power consumption (almost 11 Amps for my US friends) but really huge, 470 Air Watts of suction. The suction efficiency of this sucker is an unbelievable 39,2%, if the parameters provided by manufacturer are true (which I really don´t think so).

Vacuum cleaner´s amperage vs. wattage

Posted in Choosing the best vacuum cleaner | 0 Comments

Vacuum cleaners manufacturers (and retailers) often try to persuade the prospects to buy their products talking about their amperage (or wattage).

Typically the sales guys say something like „…buy this vac, it has an extra strong 12 Amps motor providing great suction…“. Yet, the truth is that amount of amperes or watts the vacuum cleaner takes from an electric outlet has almost nothing to do with vacuum´s suction power.

To explain it, first, let´s get back to grammar school.

The strength of an electric current is measured in amperes. One ampere is the amount of current that flows through one ohm of resistance with one volt applied. On the other hand, watt is the unit of electric power. One watt of power is used when one ampere of current flows through a resistance of one ohm.

Complicated? Don´t bother with it, you will never need it.

Sure, it is important how much power your vacuum cleaner consumes ( if you want to save on energy bills) but if you are looking for a really strong vacuum cleaner forget about amperage or wattage and ask the salesman how many air watts the vac features and what´s its airflow.

While any strong vacuum cleaner can consume 1700 Watts its actual suction power only will be 320 – 420 Watts which means the suction efficiency is 19 – 25% (the most efficient vacuums can exceed 30%).

How to calculate watts from amperes (and vice cersa)

As the American vacuum manufacturers use amperage and manufacturers from Europe use wattage when describing the vacs´power consumption, it may quite impossible for a prospective customer to compare such products and evaluate their parameters.

Comparing amperes to watts is like comparing apples with pears. No, actually it´s like comparing peanuts with pears so in order to get an overview you need to recalculate them to compare peanuts with peanuts OR pears with pears.

To calculate watts from amps just multiply number of amperes by approximately 110.
To convert amps to watts just divide watts by approx. 110. That´s all, you´re comparing the right fruits to each other…

Amperes, Wats and Air Watts

To make it even easier for all of us, following chart can be applied when comparing the power consumption of vacuum cleaners. I am multiplying amperes by 110 (sharp) to get the wattage so I expect that some accuracy lovers will raise their hands but I think we will not neetd an absolutely accurate number for this purpose.

I also added the expected suction power and I suppose that 90% of all current vacs will not exceed this range (at least not now, which is July 2007). Here we go…

5 Amp US vacuum cleaner equals to 550W European vac. The expected suction power is 105 - 138 Air Watts.
6 Amp US vacuum cleaner equals to 660W European vac. The expected suction power is 125 - 165 Air Watts.
7 Amp US vacuum cleaner equals to 770W European vac. The expected suction power is 146 - 193 Air Watts.
8 Amp US vacuum cleaner equals to 880W European vac. The expected suction power is 167 - 220 Air Watts.
9 Amp US vacuum cleaner equals to 990W European vac. The expected suction power is 188 - 248 Air Watts.
10 Amp US vacuum cleaner equals to 1100W European vac. The expected suction power is 209 - 275 Air Watts.
11 Amp US vacuum cleaner equals to 1210W European vac. The expected suction power is 230 - 303 Air Watts.
12 Amp US vacuum cleaner equals to 1320W European vac. The expected suction power is 251 - 330 Air Watts.

We will stop here as 12 Amps is the US limit for maximum amount of electricity pulled out of a wall socket.
EU doesn´t have such limits (at least I am not aware of any) and you can easily buy 1900W vacuums here (17.3 Amps).

The Army of Dust Nerds

Posted in Uncategorized | 1 Comment

In the future, when buying a Nilfisk vacuum cleaner, be sure to buy it from a certified Nilfisk “Dust Nerd”.
Company recently announced the launch of the Nilfisk Dust Academy and “Dust Nerd” program helping retailers and sales representatives to establish a consumer’s needs and close the sale.

The Dust Nerds will know the differences among particular Nilfisk vacuum models and should be able to explain benefits of important vacuum cleaner features like suction, dust pick-up, filtration or low noise.

Dust Nerds will ask prospective customers series of slick questions e.g. “how large is your home?”, “do you have carpet or hard floors?”, “do you suffery any allergies?”, “do you have a dog?”… and based upon the answers they will recommend customers the best possible Nilfisk appliance.
