What are the advantages and disadvantages of having a heat pump dryer?

Living in the woods offers both benefits and drawbacks.  The view is lovely, and the trees that block the sun protect my house from the summer heat, but producing vegetables and drying clothing outside has not worked out.  I considered all the features when purchasing my current dryer in 2017 and ultimately settled on a sizable, mid-range model (I wanted to be able to wash and dry comforters at home rather of sending them to the laundry or dry cleaners).  Despite the accusensor's "eco" settings, I usually use the "most dry" option to make sure my clothes are completely dry as they frequently remain in the dryer for 12 to 24 hours after usage because of forgetfulness.

There is a "new" dryer appliance on the street.  I use the word "new" because although this kind of dryer has reportedly been in use for a very long time in Europe and other nations, it has only been available in the US for a little under five years.  One of two varieties of ventless dryers is the heat pump model; the other kind is the condenser model.  In terms of electricity use and waste heat output into the laundry room, heat pump dryers outperform conventional dryers.

This video provides a useful explanation of how heat pump dryers operate, and it also demonstrates how frequently a heat pump dryer has to be maintained.

Regular dryers, whether electric or gas, have the following issues:

Employing a lot of energy to heat the air and then releasing it outside

Drawing conditioned air from your house to flow through the dryer (resulting in a loss of energy and around 200 cfm of conditioned air due to negative pressure)

Ultra-fine particle (UFP) release into the atmosphere inside and outside of your house

These issues could be resolved by the heat pump dryer by:

Recycling warm air as opposed to throwing it away

little to no air is drawn from the remainder of your house.

Without a dryer vent, there won't be any dusty air leaks or UFPs dumped outside.

Advantages:

Energystar.gov estimates that operating costs are at least 28% lower and as much as 50% lower than those of conventional vented dryers.

The fact that a heat pump dryer won't attempt to create a negative pressure by venting conditioned air will be welcomed by homeowners of more energy-efficient houses.

Some versions (at least those made by Miele) run on 120v, making them more adaptable.

There is no need to build a vent!  They work effectively regardless of the temperature or humidity levels in the home and may be fitted in extremely tiny places.

Because the temperature is often lower than that of conventional dryers, heat pump dryers are better at caring for fabrics.

Disadvantages:

Heat pump dryers vary in how well they work. According to this review of the Whirlpool YWED7990FW from 2019, it took significantly longer to dry clothes and significantly increased the temperature and humidity in the small laundry room and surrounding area. However, a respondent claimed that his Miele dryer, made by the well-known German company Miele, only slightly increased the temperature with a conventional dryer's drying time.  After 4 years, another Whirlpool WED99HEDW owner was content with his purchase.

The heat pump dryer requires more care to keep it operating well; a soft-head vacuum may be required periodically to clean the heat exchanger coils, and extensive cleaning by a professional may be required every few years to remove lint from the machine's interior.

In order to properly dispose of the condensed water from the garments, some heat pump dryers must be situated next to a drain.Others have periodic reservoirs that can be drained.

If you reside outside a big metro area, it could be challenging to locate a qualified technician because heat pump dryers are still rather uncommon.

Compared to traditional dryers, heat pump dryers have a greater initial cost.
