The Stratos ‘DuoClean’ floorhead contains motorised brush rolls which works on both floor and carpet, so you don’t need to keep switching with each room. It also has a slot for anti-odour capsules which keep the dust canister smelling fresh, although it’s more of a neutraliser than a perfumer. Air-Vac also offers Stainless Steel designs for abrasive material and high temperature applications and can do custom designs for your requirements. Air-Vac and AOP Technologies Miele vacuums always come recommended for their supreme AirClean filtration which claims to remove 99 per cent of allergens from the air. That’s obviously hard to prove, but it definitely left my carpets dust free. Utilities – excavates safely around existing water or gas systems, or prepares for installation of new ones. o P.E. pipe extension tube reduces utility damage by 60% compared to other methods of excavation, while providing insulation to vehicles and workers while working in high-risk areas.

Waterlift measures the suction at the foot: if the bottom of the tube was placed in water, this measures how far water would rise up the tube before gravity cancelled out the power of the motor. A vacuum with higher waterlift will be good for deep carpet cleaning. It’s also called sealed suction.Air-Vac Engineering Company is the leading manufacturer of air-operated vacuum pumps worldwide. For over 50 years, the company has provided dozens of industries with reliable products that were made to last. They also offer customized products for clients with special requirements. The best part, and the feature American brand Shark is so famous for, is the incredible anti hair wrap technology. Unlike previous Shark models it’s almost 100 per cent effective, and that’s coming from someone with four long-haired cats and two Labradors. I’d choose this over Dyson’s detangling technology.

Experts say what you should really be comparing is the output power, given in airWatts. This is calculated by multiplying two other measurements (told you this was complicated): Vacuum excavation is the most cost-effective means of moving and collecting debris, soil, and waste material. This is due to the speed and efficiency of the VAC-EX AIR- VAC® machine.In an ideal world all vacuum cleaners would multiply these to give an output rating measured in airWatts. Sadly it is rarely available. Some manufacturers list waterlift (in mm), some airflow (in m 3/h), some nothing. We have listed whatever information is available to help you compare, but our assessment of the vacuum cleaners’ power is based on at-home tests and expert advice. The ground can now be safely vacuumed into the AIR-VAC and stored in the 0.2m cubed integrated skip. Air lance and dig pipe are manufactured from HDPE Plastic which will insulate the user from any live underground cable.

Telecommunications – assists cable-laying efficiency and safety by easily identifying the location of existing utilities. Civil engineering and infrastructure – used in building roads and large-scale construction projects.What are the advantages of the R.G.S range of compressed air-powered vacuums over electrical powered vacuums? Sebo originally manufactured industrial strength vacuums for German hotels and is still the standard for professional floor cleaners. We know from other vacuums that those that started commercially are often the most durable.

Vacuum cleaners have become an unexpected specialist subject of mine as a writer on the Telegraph Recommended product review section, and no vacuum has impressed me more than this. However, a cordless vacuum cleaner may not be the best choice if you have lots of carpet or a large area to clean. Corded upright and cylinder vacuums aren’t limited by battery life, and in most instances they have more powerful suction. Petrova also recommends looking for a vacuum with a HEPA filter, “as they provide the best method of filtration and traps even particles too small to see with naked eye.” Construction – useful for foundation laying in residential, commercial, and industrial construction projects. Landscaping – removes obstructions such as tree roots, transports soil, and works around vegetation. Before vacuum excavation became available in the 1950s, hydro excavators and manual methods were the norms. While the technology has existed for several decades, it has taken time for air vacuum excavators to become globally accessible. Vacuum excavation is now as refined and efficient as ever before, and has a wide range of applications. It is the preferred excavation method for engineering, construction, and utility projects.We’re big fans of the Shark Stratos Cordless Vacuum (also reviewed in our best vacuums for pet hair piece) but the corded just takes the edge for power. This corded model has 450 Watts of power, compared to the cordless which only has a 309 Watt motor. Plus - the corded is cheaper. According to professional cleaner Katerina Petrova of the Happy House Cleaning Company, that largely depends on the area you have to clean, as well as your budget. o A small footprint means the vacuum excavator can be operated in a third less space than a mini-digger. Air-Vac produces a wide range of vacuum pumps for different applications. With two Venturi designs and six concepts, Air-Vac provides the flexibility of design to meet your specific vacuum needs. In our tests it was faster and less ‘dithery’ than other robot vacs, forming a confident map of its surroundings. Trundling around quietly (it’s no noisier than a desk fan), it was impressive on hard floors and while did leave some fine dirt behind on carpets on the first pass, it got it up on a targeted clean.
