1.Weak Airflow, Extremely Low Drying Efficiency
Problem Description: After turning on the machine, the airflow is weak. The inner fur layer of thick-coated dogs and long-haired cats takes a long time to dry, and damp fur remains in localized areas.
Solution:
Check whether the air inlet is blocked: Obstruction of the air inlet by pet hair, curtains, or debris will lead to insufficient air intake. Clear the obstructions to ensure the air inlet is unobstructed.
Switch the air nozzle and gear: The flat air nozzle concentrates airflow more effectively, which is suitable for drying thick fur locally; adjust the gear to high airflow to avoid insufficient power in low gear mode.
Clean the air duct and fan blades: After prolonged use, hair and dust may accumulate in the air duct. Disassemble the air nozzle and hose assembly, and clean internal debris with a brush; at the same time, wipe the motor’s fan blades to prevent hair entanglement from reducing rotational speed. If the airflow remains weak after the above steps, contact customer service for inspection and repair.
2.Excessively High Air Temperature, Prone to Scalding Pets
Problem Description: The air emitted during hair drying is too hot, with an obvious burning sensation when close to the pet’s skin, and may even cause redness of the pet’s skin and resistance to being dried.
Solution:
Immediately switch to low-temperature gear: Stop using the hot air gear and switch to cool/warm air gear; some models have a constant temperature control function, so ensure this function is enabled to avoid loss of temperature control. Clean dust on the
heating wire: Accumulated hair and dust on the heating wire will affect heat dissipation, leading to local overheating. After powering off and cooling down, gently clean surface impurities on the heating wire with a soft brush.
Check if the thermostat is malfunctioning: A faulty thermostat will cause the temperature to become unadjustable. If the temperature does not change after switching gears, contact after-sales service to replace the thermostat. Maintain distance between the air outlet and the pet: Keep the air outlet 10-15cm away from the pet’s skin, and avoid directly blowing on the same area for more than 30 seconds at close range.
3.Hair Flies Everywhere During Drying, Polluting the Environment
Problem Description: During the drying process, the pet’s loose hair is blown all over the room, adhering to furniture and clothing, making it difficult to clean.
General Solution:
Use hair suction tools: Comb the pet’s loose hair with a pet comb before drying, and use a small vacuum cleaner while drying to promptly suck up the blown-off hair.
Use an air-collecting hood/anti-flying hair nozzle: Choose a nozzle with an air-collecting function to reduce the air outlet range and minimize hair diffusion; some models are compatible with anti-flying hair accessories, which can be installed for use.
Control the hair drying environment: Dry the pet’s hair in a closed space (such as a bathroom), close doors and windows, and use a vacuum cleaner to thoroughly clean any loose hair in the room after drying. Blow along the direction of hair growth: Blow according to the direction of the pet’s hair growth to avoid fluffy hair that flies caused by reverse blowing, and also reduce the pet’s discomfort.
4.Insufficient Suction of the Hair Vacuum, Unable to Pick Up Pet Loose Hair
Problem Description: After turning on the machine, the suction is weak. The pet’s loose hair and dander on sofas and carpets cannot be picked up, and hair may even be sucked up and then fall off.
Solution:
Empty the dust box/dust bag: An overfilled dust box or dust bag will block the air-flow channel, which is the most common cause of reduced suction. Empty the internal hair timely, and wipe the residual dust on the inner wall of the dust box during cleaning.
Clean/replace the filter: HEPA filters and primary filters are easily blocked by fine dander. Remove the filter and rinse it with clean water (do not scrub with a hard-bristled brush to avoid damaging the filter fibers), and reinstall it only after it is completely dry; if the filter is damaged or has been used for more than 3 months, directly replace it with the same-model accessory.
Unblock the air duct and suction head: Disassemble the suction hose and brush head, and clean the tangled hair and debris in the hose with a long rod or tweezers; check the rolling brush of the head. If it is entangled with a lot of hair, carefully cut it off with scissors and clean it to ensure the rolling brush rotates smoothly.
5.Hair Blockage in the Hair Vacuum Air Duct Causing “Back Blowing
Problem Description: During hair suction, the hair does not enter the dust box but instead blows back from gaps in the machine body or air inlet, polluting the surrounding environment.
Solution:
Check the filter installation: If the filter is not installed, installed incorrectly, or damaged, the hair cannot be effectively intercepted. Install the filter correctly according to the instruction manual, ensuring the edge of the filter is completely fitted into the slot.
Clean the one-way valve: Some models have a one-way valve in the dust box to prevent air backflow. If the one-way valve is blocked by hair, back blowing will occur. Clean the hair and dust from the one-way valve with a cotton swab to ensure the valve opens and closes smoothly.
Check the dust box seal: If the dust box cover is not tightly closed or the sealing ring is aging, air leakage will cause back blowing. Reclose the dust box cover and confirm the buckle is in place; if the sealing ring is aging, contact customer service for replacement.
6.Noticeable Odor from the Hair Vacuum (Musty Smell/Burnt Smell/Pet Odor)
Problem Description: After turning on the machine, it emits a musty smell, rotten pet hair smell, or burnt smell, polluting the indoor air and potentially affecting health.
Solution:
Thoroughly clean and dry: After emptying the dust box each time, clean the dust box and filter with a neutral detergent, rinse them thoroughly, and place them in a well-ventilated place to dry completely to prevent mold growth from moisture.
Regular disinfection: Wipe the inner wall of the dust box with a diluted pet-specific disinfectant every week to kill residual bacteria; the filter can be placed in sunlight for 1–2 hours to remove odors and any mold.
Replace the filter in a timely manner: If the filter has mold spots or is damaged, it cannot be fully cleaned. Replace it with a new filter immediately to avoid odor diffusion and bacterial spread.
7.Severe Heating of the Body/Handle of the Blowing-Suction 2-in-1 Machine, Even Too Hot to Touch
Problem Description: After using it for a few minutes, the temperature of the machine body or handle rises rapidly, and it feels too hot to hold, raising concerns about motor burnout.
Solution:
Control the continuous use time: These blowing-suction 2-in-1 machines are prone to overheating when working continuously. It is recommended to rest for 10 minutes after every 20–30 minutes of use to avoid motor overload.
Clean the heat dissipation port: Blockage of the heat dissipation port on the machine body by hair and dust will hinder heat dissipation. Gently clean the heat dissipation port with a brush to keep it well-ventilated.
Use the original power supply: Non-original power supplies with voltage mismatch will cause abnormal motor operation and generate excessive heat. Be sure to use the original power supply to avoid voltage instability.
8.Failure to Switch Between Blowing and Suction Modes of the 2-in-1 Machine, Function Stuck
Problem Description: After pressing the mode switch button, the machine still stays in the current mode; or the function is abnormal after switching (such as blowing air containing hair when in blowing mode, or no air when suctioning).
Solution:
Power off and restart to clear program faults: Unplug the power supply (remove the battery for wireless models), let it stand for 10 minutes, and then reconnect power/install the battery. Most temporary program freezes can be solved by this method.
Confirm that the accessories are installed in place: If the suction head and blowing head of some models are not fully snapped into the port, the safety lock will be triggered, preventing mode switching. Reinstall the accessories until the buckle makes a “click” sound, ensuring that the duct switching component is in place. If the problem persists after restarting, contact after-sales service for inspection and repair.
9.Excessively Loud Operation Noise, Emitting Sharp Abnormal Sounds
Problem Description: After turning on the machine, it emits sharp whistles, friction sounds, or vibrational noises. The noise difference between blowing and suction modes is obvious, scaring pets and affecting the home environment.
Solution: Whistling is mostly caused by poor air duct sealing, through which high-speed air flows via gaps. Check the installation status of the dust box, filter, and hose; replace aging sealing rings, and ensure all components are tightly fitted without loosening. Eliminate friction sounds (due to foreign object entanglement): After powering off, remove the side cover of the machine body, clean tangled hair from the motor fan blades and rolling brush bearings; check for foreign objects stuck in the blowing head and suction head, clean them, and manually rotate to test smoothness. Shock absorption and noise reduction: Place the machine on a flat, hard surface, and put a silicone shock absorption pad under it to reduce resonance noise during operation; avoid using it on resonance-prone surfaces such as hollow wood floors and fabric sofas.
