I've been using these bucket vacuums for six years now. I heard about them from another business owner in the same field who has been using them for a long time. This is the best vacuum cleaner for technicians. This vacuum cleaner conveniently fits a 5 gallon bucket for easy waste disposal. The vacuum cleaner works in both wet and dry places. Example: Can range from vacuuming lint out of a dryer cabinet to vacuuming water out of a washing machine with a faulty drain pump. For use in all locations we can have 120v. A 6.5 amp motor provides enough power to drive the suction fan. This vacuum cleaner never loses power and is very durable. I always give this vacuum cleaner a 5. We expressly recommend this vacuum cleaner for use in the field of repair and maintenance.
