Kenmore 31140 Review

Kenmore Pet Friendly 31140 – 2 Motors for Sustained, High Power on Any Surface

Kenmore 31140

The Kenmore Pet Friendly 31140 is the upright and bagged model with high power and the enhanced HEPA filtering for quality cleaning surfaces of all types. The budget-friendly machine is remarkable for its five height levels, a dirt sensor, direct drive, and two motors.

The product’s size is 14.5 x 14.5 x 45.75 inches. It is fitted with a 30-feet power cord, 10-feet hose, and features a cleaning path of 12.75 inches. The machine weighs 19.5 pounds.


The Kenmore 31140 features great power of 12 amps and airflow to collect small and large debris (cereal, cat litter, flour, rice, sand, etc.) from hard and soft coverings. Besides, it has four adjustable levels of height to make vacuuming effective regardless of the pile’s length:

  • HI is suitable for deep-pile rugs.
  • MED HI is relevant to medium and deep-pile carpets.
  • MED LO does its job on low and medium-pile coverings.
  • LO fits mats, low-pile rugs, and bare floors.

The Kenmore 31140 vacuum cleaner has wheels, meaning no influence on the angle of the powerhead when a user tilts the vacuum handle up and down.

The Power Flow technology ensures no suction power losses when a machine transits from bare floor to a rug. The machine has an 85-decibel level of noise at pick power that is rather quiet for such a large device.

The Kenmore 31140 Pet Friendly upright vacuum is equipped with a suction motor for cleaning hardwood, tile floors, and delicate carpets with one of the accessories. Besides, it has the agitator motor that works paired with a suction one and is necessary for cleaning usual rugs. Note that the branded Thermal Protector switches the machine off automatically once the normal airflow to the suction motor is clogged. Moreover, the By-Pass Valve protects the suction motor from the overheating. The agitator motor is also protected against damage.


The Kenmore 31140 vacuum is fitted with the height adjust selector located on the nozzle. The latter has a headlight that is bright enough to illuminate the carpet well in poorly lit areas. The button to set the machine for carpet and floor vacuuming is on the handle. A full bag indicator underneath prevents the vacuum bag from overfilling.

The machine’s power cord wraps around two hooks on the back of the unit, and the top hook turns 180 degrees to remove the coil effortlessly. It has an extendable aluminum telescopic wand to escape fiddling with multiple parts. The set of attachments also includes the air driven pet/upholstery rotating brush for vacuuming furniture, drapes, and stairs, typical crevice tool, and a Pet HandiMate tool with hard-rubber brushes.

No extra cloth bags in the package (they are rather pricey on sale) and a rigid hose (even with a suction control) are the flaws that might ruin a glimpse of this model.


Summing up the Kenmore 31140 review, I’d like to stress that this model is suitable for those who put strong suction ahead of such inconveniences as big weight and too sturdy hose. An extendable wand and three attachments provide deep cleaning of all the surfaces in the house. A wide cleaning path allows vacuuming in large rooms faster. However, it is a bit awkward in tight areas and doesn’t fit small bathrooms.
