This compact and easy to carry handheld vacuum cleaner is easy to operate and store. Suck up dirt and wet & dry with ease. With a dirt capacity of 410 ml, and a liquid capacity if 140 ml, you can clean more without the need to constantly empty the filter. This handheld vacuum is excellent for cleaning upholstery, small carpets, and little messes.

The Hoover H84-7WD-ZA Wet & Dry Hand Vacuum is a powerhouse packed into a compact design. With its 7.4V lithium battery, you can enjoy 18 minutes of cordless cleaning power, whether you're tackling wet spills or dry messes. Charging it up takes just 5-6 hours, and the handy charging indicator keeps you in the loop. Plus, with accessories like a crevice tool, wet & dry squeegee, and a charging wall mount, this vacuum is ready to handle any mess you throw its way!

Powerful performance: The battery powered CVH 2 handheld vacuum cleaner can easily, effortlessly and powerfully remove existing dirt, including crumbs, dust and hair from furniture, floors and cars. Its compact, lightweight design means that this vacuum cleaner is also easy to operate and store away. In addition, particularly clean exhaust air is ensured by the two-step washable filter system made of fine steel mesh for coarse dirt and hair, and also a downstream HEPA 12 hygiene filter (EN 1822:1998).

Providing examples of applications, Power Vacuum Tubes Handbook, Third Edition examines the underlying technology of each type of power vacuum tube device in common use today. The author presents basic principles, reports on new development efforts, and discusses implementation and maintenance considerations. Supporting mathematical equations and extensive technical illustrations and schematic diagrams help readers understand the material. Translate Principles into Specific Applications This one-stop reference is a hands-on guide for engineering personnel involved in the design, specification, installation, and maintenance of high-power equipment utilizing vacuum tubes. It offers a comprehensive look at the important area of high-frequency/high-power applications of microwave power devices, making it possible for general principles to be translated into specific applications. Coverage includes power grid tubes-triodes, tetrodes, and pentodes-as well as microwave power tubes such as klystrons, traveling wave tubes, gyrotrons, and other high-frequency devices. These vacuum tubes are used in applications from radio broadcasting to television, radar, satellite communications, and more. Explore a Wide Variety of Methods in Power Vacuum Tube Design This third edition includes updates on vacuum tube technology, devices, applications, design methods, and modulation methods. It also expands its scope to cover properties of materials and RF system maintenance and troubleshooting. Explaining difficult concepts and processes clearly, this handbook guides readers in the design and selection of a power vacuum tube-based system. What's New in This Edition Includes two new chapters on properties of materials and RF system maintenance and troubleshooting Contains updates and additions in most chapters Identifies key applications for commercial and scientific research Examines the frontiers of materials science directly impacting construction, reliability, and performance Reviews methods of power tube design for more efficient, longer-lasting tubes Features updated illustrations throughout to clarify and explain fundamental principles and implementation considerations
