With a 4 gallon dirt tank and 600 air watts of suction power, the Electrolux PU3650 QuietClean Central Vacuum Unit is one vacuum you don't want to miss out on. Clean rooms up to 8000 sq. ft by purchasing our PowerTeam Accessory Kit that includes a 35 dual voltage crushproof hose, 38 inch telescopic wand, 14 inch hard floor brush, dusting brush, crevice tool, upholstery tool, and hose hanger. Unlike some models, this central vacuum unit has a built-in LCD display that always tracks your systems performance and tells you when you need to empty out your dirt tank.

Hate changing filters? Don't worry, the Electrolux PU3650 utilizes a permanent self-cleaning filter that never needs to be replaced. Hate loud noises? No problem! Electrolux built this vacuum with sound-resistant technology. For extra peace of mind, the Electrolux PU3650 comes with a 10 year warranty.

Installing the Power Unit

The power unit is usually mounted on the wall in an "out of the way" location, such as a garage, basement, or storage room. They are installed 48 inches above the floor to allow for easy removal of the dirt tank, but never less than 12 inches from the ceiling because that does not provide adequate space for motor ventilation. Also, you should never install in an area where the temperature exceeds 120 degrees. Depending on wall type, you may need to use mounting bolts or anchors to hold the central vacuum power unit in place. Finally, connect the low voltage wires, tubing, and plug the unit into the wall.

Care and Maintenance

To get the most out of your central vacuum cleaner, you need to perform regular maintenance and safety checks. For example, the motor brushes should be checked by an authorized dealer after every 500 hours of use. You should also keep the power unit free of dust and debris by frequently dusting with a clean, soft cloth. Never use more than one inlet at a time, and never place anything on top of the power unit that could prevent proper motor ventilation. Finally, the Electrolux PU3650 cannot safely pick up construction debris.

If you ever have any trouble with your central vacuum unit, you are more than welcome to dial 1-866-972-8227 to speak with a trained vacuum specialist at absolutely no cost to you.

Local dealer quoted me $2999 to buy / install this exact unit and replace the basic vacuum head I had. I found same thing at eVacuumStore and even bought the SEBO vacuum kit all for under $1000. Installed it myself (very easy) ... amazing quality and performance. Customer Service was exceptional!

I bought this as a replacement unit. The unit is extremely quiet. Sometimes I don't even know the unit is operating.The unit was easy to install.The unit is installed in the basement. I installed the muffler and vented the unit to the exterior. The unit has plenty of power for a 2 story 3000 sf residence. the eVacuunStore was knowledgeable and easy to deal with.The unit arrived in 2 days. This is a better unit than the local dealer and at a much better price.

Q & A

Customers Questions and Answers
Question:We are replacing a AFUERA11 CV3291M wil this be a compatable exchange - (01/02/2020)
Answer:Yes, this will replace your current model.
Question:What is the decibel (db) level of the units motor when on? - (01/26/2019)
Answer:70DB with the muffler installed.
Question:I have an older central vacuum cleaner that I believe the motor has gone bad. It’s a “Signature 900”, I believe it was sold by Montgomery Wards. On the name plate tag it says “Eureka 900, 115 volt, 13 amps. My parents owned this home before I retired from the Navy & purchased it from them. My father installed this vacuum system probably 40+ years ago. It is vented to the outside with 2” pvc and has 2 runs of 2” pvc for suction. The 2 plug in ports are located in the hallway. This is a 3 bedroom rambler home approximately 1800 sq ft on the main level with the basement 3/4 finished. What unit would be best for replacing the old unit? Located alongside the vacuum head is a junction box with a switch as the head has a utility port on the front and you move the toggle switch to switch between upstairs ports and the utility port. I believe this junction box is where it switch’s from low level to 115 VAC. I have looked at various units on your website but am a little confused as to what is best. I worked in electronics in the Navy so I have some knowledge of electrical/electronics. Thank you. - (11/13/2018)
Answer:The nutone pp500 would be a good fit for a home that size:

Question:What type of motor does the PU3650 have? Is it a peripheral by-pass, flow-thru, or tangential by-pass motor? - (07/06/2016)
Answer:The PU3650 uses a tangential by-pass motor.
Question:When you say that the unit has to be 48 inches from the floor, do you mean 48 inches from the top of the unit to the floor to allow for access to the collection tank? You don't mean 48 inches from the bottom of the unit to the floor do you? - (06/11/2016)
