OVO OVO-750ST-35H Central Vacuum System, 750 Airwatts, 35 L Hybrid Filtration

For cleaning several rooms without carrying a portable vacuum from space to space, the OVO-750ST-35H is a central vacuum designed for connection to a home’s piping network. Its 750 airwatts and three power levels support cleaning across carpet, hardwood, upholstery and stairs, as well as picking up pet hair.

The 35 L bottom-load canister gives the system a substantial dust capacity, while hybrid filtration lets you choose between bagged and bagless operation. It’s a practical approach for whole-home cleaning, especially when you already have compatible central-vacuum piping.

What matters most

A 5.7-inch, two-stage Ametek motor delivers 750 airwatts and 140.2 CFM. Soft start/stop technology is designed to add 20% to the motor’s life expectancy. Three power levels let you select a setting for the task, from floor cleaning to upholstery and stairs.

The filtration system works with or without the included triple-layer disposable bag. For bagless operation, use the included permanent, machine-washable filter. The bag offers a contained way to handle dust when emptying the canister, the washable filter provides a reusable option. Buyers often highlight the suction and ease of installation, while feedback on overall performance is mixed.

An integrated muffler and noise-blocking foam in the motor compartment are designed to reduce operating noise. The rolled-steel canister has a bottom-load design, so the dust container can be removed from below for emptying.

How it fits

This is a central vacuum unit for indoor use, intended to connect with an existing piping network that meets ASTM F2158 requirements. Its listed dimensions are 38 L × 38 W × 89 H centimetres, and it can be installed with the air intake at the top to suit the connection layout. The manufacturer describes a 120 V AC system with a regular 15 A plug-in connection, rather than a dedicated circuit.

Compared with a portable vacuum that you move between rooms, a central system uses the home’s inlets for cleaning across multiple spaces. That makes the OVO a useful fit for a household set up for central vacuuming, it can also serve carpeted and hard floors, upholstery, stairs and pet-hair cleanup. Flexible pipes are available separately if needed for installation.

Tips for day-to-day use

Choose bagged or bagless filtration based on how you prefer to empty and maintain the system. With a disposable bag installed, dust is contained in the bag during removal. For bagless use, the permanent filter is machine washable, follow its care instructions before returning it to the unit. The built-in LED indicator provides status information, including when the unit signals that a bag change or attention to the power unit is needed.

Use the three power levels to match the setting to the cleaning task. The system is intended for indoor cleaning, with recommended uses ranging from everyday floors to upholstery, stairs and larger spaces.

Before you decide

Can it run without disposable bags? Yes. Use the included permanent, machine-washable filter for bagless operation, or choose the included triple-layer disposable filtration bag.

Can it connect to an existing central-vacuum network? Yes, provided the piping network meets ASTM F2158 requirements. Flexible pipes are available separately for installation needs.

What helps manage operating noise? The motor compartment has an integrated muffler and noise-blocking foam, both designed to reduce noise while the system runs.

Should you buy it?

The OVO-750ST-35H suits households looking for a fixed central-vacuum system with strong listed suction, a choice of bagged or bagless filtration and a 35 L bottom-load canister. If your home has a compatible central-vacuum network, its multi-surface use, three power levels and noise-reducing features make it a capable setup for regular cleaning across rooms.
