Please ask me any questions regarding the efficiency, durability, and value of 99.5% of today's vacuum cleaners, residential and commercial. I am able to help, also, with your residential carpet cleaners and vapor steamers. I cannot answer questions such as "how much should I pay for my vac?" "how often should I change the bag, belt, filter?" or "how often should I vacuum?" , etc. I also will not advise you how to use equipment for other than its original application; including any disassembly or modification not approved by the unit's manufacturer.
I am the owner of a well-established (sixty-plus years), family-owned & operated vacuum retail and repair business. We are a full service/warranty center for 99.5% of vacuums manufactured.
I, personally, have extensive hands-on experience with today's most popular vacuum cleaners, I have not only used the vacs in my own home, I have repaired them. I have been in the floor care industry for over 25 years.
I have attended certification seminars with the industry's trade association. My education, however, has been mostly hands-on, carrying on a sixty year old tradition in a brick and mortar 'mom & pop' location.
