The AD 4 Premium ash and dry vacuum cleaner in energy class A+ (scale A+++ to D), with a 600 W turbine and exhaust air filter, impresses with its high and long-lasting suction power. Its integrated filter cleaning system cleans the additional filter at the touch of a button, so that the suction power is immediately increased again. The one-piece filter system (with robust flat-fold filter and filter for metals and coarse dirt) as well as the practical handle on the tank ensure quick and convenient emptying of the dirt container without contact with dirt. In addition, the high-quality, non-flammable materials offer maximum safety when collecting ash. Thanks to the curved hand tube, ash residues are completely sucked up - even in corners and hard-to-reach places in the fireplace. Together with the included floor nozzle for cleaning hard surfaces and the high-quality chrome-plated suction hoses, the AD 4 Premium can be used as a high-quality dry vacuum cleaner.

Same summary

The Karcher AD4 Premium 1.629-731.0 ash vacuum cleaner is designed for users who regularly clean ashes from fireplaces, stoves or grills and need an effective solution for removing fine dust and particles. Due to the emphasis on the appropriate dust container and power, it is suitable for households where ash cleaning is frequent, as well as for users who want simple maintenance and easy handling. The model is less suitable for people looking for a versatile vacuum cleaner for textile surfaces or deep cleaning of other materials, as it specializes mainly in vacuuming ash and coarse particles. The advantage of the product is better filtration and adaptation to tasks where air cleanliness after ash cleaning is important.

Answers to frequently asked questions

Can I use this vacuum cleaner to vacuum anything other than ash?

The vacuum cleaner is designed primarily for removing ash from fireplaces, stoves and grills. We recommend that you do not use it for wet materials or liquids, as the filter design is adapted to fine dust and ash, not for wider use than with classic vacuum cleaners.

When should the filter on an ash vacuum cleaner be replaced or cleaned?

It is recommended to clean the filter after each use or at least regularly to maintain suction power and effective filtration of fine particles. This is especially important when vacuuming large amounts of ash or very fine dust.

Is this vacuum cleaner suitable for use with warm ash?

The ash vacuum cleaner is intended exclusively for vacuuming completely cooled ash. Use with hot material may damage the filter or internal parts of the device and is unsafe for the user.

What should I look for when choosing an ash vacuum cleaner?

When choosing, the most important factors are the container capacity and the quality of filtration, to reduce the frequency of emptying and prevent fine dust from returning to the room. For more detailed recommendations, our vacuum cleaner selection guide can help you.

Is vacuum cleaner maintenance difficult?

Maintenance is simple – empty the ash container regularly and clean the filters according to the manufacturer's instructions. This ensures a long service life and continued efficiency of the device.
