Vacuum Cleaners Discussions

Here's the latest from Siemens. Expect a Bosch equivalent any time soon: taken from www.appliancist.com/green_appliances/siemens-vacuum-cleaner-offers-green-power.html



"...The new Siemens Z 5.0 is the premium compact vacuum cleaner capable of achieving a very impressive 47-liter per second suction rate. This compact powerhouse comes with the special Siemens motor that employs the latest super efficient XTRM compressor technology, providing the basis for such an incredible performance. With the Z 5.0 Extreme Power edition, you are getting a highly optimized air flow, making it an alternative to the larger Z 6.0 Extreme Power which creates 50-liter power per minute rate...The old equation a lot of watts = more power is no longer valid in modern vacuum cleaners. What ultimately matters is the force that is actually applied to the carpet. The air flow is much more relevant as it indicates how much air is drawn per second. And more air per second means more dust and dirt gets vacuumed. The compact Siemens Z 5.0 Extreme Power has a 4.5 liter dust bag while its hose and intake manifold diameter is 20% larger than those of the regular vacuum cleaners. The result is lesser air resistance, turbulence and fewer bottlenecks that typically slow down the air flow.

The vacuum also comes with the Siemens washable Ultra HEPA filter and the high-quality MegaAir SuperTex filter bag to hold back even the smallest particles. When you change the filter bag, a special hygiene seal ensures that no dust or dirt to return to the outside, making the Siemens Z 5.0 compact vacuum suitable for allergy sufferers..."

The new Siemens Z6.0 comes in two powerful and extremely efficient models, the Z6.0 Power and the Z6.0 Eco. Boasting the symbolic green power cord, these vacuums are setting the bar high in terms of environmental features and operating economy. Using lower wattage but delivering top performance, each energy saving vacuum offers a new dimension in floor care. Siemens Z6.0 cleaners combine the enhanced efficiency, offered by the Siemens compressor technology with a new aerodynamic system, designed to improve airflow within the cleaner. This results in up to 50% savings on electricity plus a significantly increased air throughput. And the new, green tagged air guidance system releases airflow blockages and prevents the air swirls that impair efficiency. To match their advanced aerodynamic system, both models feature innovative and powerful motor fans that resemble an aircraft turbine. Due to their aerodynamically-shaped impellers that reach a top speed of 800 kph, these Siemens vacuum cleaners convey exceptionally high air volumes while minimizing energy consumption..."






Despite the claims its a pity the main exhaust filter is at the top, giving owners a free hot facial not doubt just like Miele.

Dont know the price ranges as yet Carmine - but I'm speculating that since they are based on the expensive Free'e series, they will be highly priced and put into Miele S5 territory.

Tough market and price range to launch new products in now.  S2 venue would be more realistic epsecially in current economic times.  Then move up into the S5 territory.

Carmine D.

Nope. The Siemens/Bosch have a compact line up already - this series would be premium, sitting alongside Miele S5.

An advert for the Bosch with the line '50% energy saving with no loss of performance.' has today been banned in the UK by the ASA, due to lack of evidence to back up the claim.

Hi M00seUK,

As the main factor re vacuum cleaner energy consumption is rate of use time versus power draw, I think there's going to be a lot of back and forth on the issue. Either a high power draw vac that actually shortens vacuuming time by way of single or double-pass deep clean ability OR a high-efficiency vac that runs at half or less todays standard power draw appears. We've already had the latter by way of several American brands, especially the Electrolux G and the Hoover Convertible. However, the low-watt vacuum motor has been long abandoned.

I don't think there's any way to seriously broach energy consumption issues without readapting to simply using less power draw.

Having said all that and even though vacuuming can be a lengthy and labor intensive task, I'll never be quite convinced that it puts all that big a hit on an electric bill. People, even the very fussy frequent cleaners, don't vacuum that long. You far more electricity by way of cooking appliances, refrigerators and clothes dryers.

I'd add be sure to read the consumer reviews included with this article. They were very favorable giving me the feeling that maybe the finger pointing and tattling is just another matter of sour grapes on Dyson's part.

Best,

Venson
